107-408: The key element of the toy is the magnetophoretic display panel, filled with a thick, opaque white liquid containing tiny dark magnetic particles . These particles can be drawn to the drawing surface by a magnet-tipped stylus or optionally-provided shapes, or removed to the hidden back side by a sliding eraser bar. The middle layer is divided into a honeycomb of cells, keeping the liquid static and

214-665: A " keyboard bar " form factor, like the BlackBerry line, Windows Mobile smartphones, Palm Treos , and some of the Nokia Eseries . A few hid their full physical QWERTY keyboard in a sliding form factor , like the Danger Hiptop line. Some even had only a numeric keypad using T9 text input , like the Nokia Nseries and other models in the Nokia Eseries . Resistive touchscreens with stylus -based interfaces could still be found on

321-504: A "devices and services" company. Despite the growth of Windows Phone and the Lumia range (which accounted for nearly 90% of all Windows Phone devices sold), the platform never had significant market share in the key U.S. market, and Microsoft was unable to maintain Windows Phone's momentum in the years that followed, resulting in dwindling interest from users and app developers. After Balmer

428-736: A "smartphone" began as a prototype called "Angler" developed by Canova in 1992 while at IBM and demonstrated in November of that year at the COMDEX computer industry trade show. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator . In addition to placing and receiving cellular calls , the touchscreen-equipped Simon could send and receive faxes and emails . It included an address book, calendar, appointment scheduler, calculator, world time clock, and notepad, as well as other visionary mobile applications such as maps, stock reports and news. The IBM Simon

535-431: A 3.5" capacitive touchscreen with twice the common resolution of most smartphone screens at the time , and introduced multi-touch to phones, which allowed gestures such as "pinching" to zoom in or out on photos, maps, and web pages. The iPhone was notable as being the first device of its kind targeted at the mass market to abandon the use of a stylus, keyboard, or keypad typical of contemporary smartphones, instead using

642-401: A bistable electronic display solely by means of printing. This system may satisfy the practical requirements of electronic paper." This used tiny microcapsules filled with electrically charged white particles suspended in a colored oil . In early versions, the underlying circuitry controlled whether the white particles were at the top of the capsule (so it looked white to the viewer) or at

749-400: A color filter. The colors are cyan, magenta, and yellow , which is a subtractive system, comparable to the principle used in inkjet printing. Compared to LCD, brightness is gained because no polarisers are required. Electrofluidic display is a variation of an electrowetting display that place an aqueous pigment dispersion inside a tiny reservoir. The reservoir comprises less than 5-10% of

856-439: A dependence on third-party sources providing applications for multiple platforms. The advantages of a design with software powerful enough to support advanced applications and a large capacitive touchscreen affected the development of another smartphone OS platform, Android , with a more BlackBerry-like prototype device scrapped in favor of a touchscreen device with a slide-out physical keyboard, as Google's engineers thought at

963-451: A few smartphones, like the Palm Treos , which had dropped their handwriting input after a few early models that were available in versions with Graffiti instead of a keyboard. The late 2000s and early 2010s saw a shift in smartphone interfaces away from devices with physical keyboards and keypads to ones with large finger-operated capacitive touchscreens. The first phone of any kind with

1070-462: A film that can be integrated into architectural design such as "wall, ceiling panel, or entire room instantly." The disadvantage of these current color displays is that they are considerably more expensive than standard E Ink displays. The jetBook Color costs roughly nine times more than other popular e-readers such as the Amazon Kindle. As of January 2015, Prism had not been announced to be used in

1177-424: A hydrocarbon oil. A dark-colored dye is also added to the oil, along with surfactants and charging agents that cause the particles to take on an electric charge. This mixture is placed between two parallel, conductive plates separated by a gap of 10 to 100 micrometres . When a voltage is applied across the two plates, the particles migrate electrophoretically to the plate that bears the opposite charge from that on

1284-404: A large capacitive touchscreen as the sole means of interaction, and led to the decline of earlier, keyboard- and keypad-focused platforms. Later, navigation keys such as the home , back , menu , task and search buttons have also been increasingly replaced by nonphysical touch keys, then virtual, simulated on-screen navigation keys, commonly with access combinations such as a long press of

1391-519: A large capacitive touchscreen was the LG Prada , announced by LG in December 2006. This was a fashionable feature phone created in collaboration with Italian luxury designer Prada with a 3" 240 x 400 pixel screen, a 2-Megapixel digital camera with 144p video recording ability, an LED flash , and a miniature mirror for self portraits. In January 2007, Apple Computer introduced the iPhone . It had

1498-464: A large touchscreen for direct finger input as its main means of interaction. The iPhone's operating system was also a shift away from older operating systems (which older phones supported and which were adapted from PDAs and feature phones ) to an operative system powerful enough to not require using a limited, stripped down web browser that can only render pages specially formatted using technologies such as WML , cHTML , or XHTML and instead ran

1605-481: A limited amount of cellular Internet access. PDA and mobile phone manufacturers competed in reducing the size of devices. The bulk of these smartphones combined with their high cost and expensive data plans, plus other drawbacks such as expansion limitations and decreased battery life compared to separate standalone devices, generally limited their popularity to " early adopters " and business users who needed portable connectivity. In March 1996, Hewlett-Packard released

1712-752: A major partnership with Microsoft, under which it would exclusively use Windows Phone on all of its future smartphones, and integrate Microsoft's Bing search engine and Bing Maps (which, as part of the partnership, would also license Nokia Maps data) into all future devices. The announcement led to the abandonment of both Symbian, as well as MeeGo —a Linux-based mobile platform it was co-developing with Intel. Nokia's low-end Lumia 520 saw strong demand and helped Windows Phone gain niche popularity in some markets, overtaking BlackBerry in global market share in 2013. In mid-June 2012, Meizu released its mobile operating system, Flyme OS . Many of these attempts to compete with Android and iPhone were short-lived. Over

1819-402: A near- lambertian viewing characteristic, result in an 'ink on paper' look. But such displays have to date suffered from short lifetimes and difficulty in manufacture. Here we report the synthesis of an electrophoretic ink based on the microencapsulation of an electrophoretic dispersion. The use of a microencapsulated electrophoretic medium solves the lifetime issues and permits the fabrication of

1926-523: A redesigned user interface, support for gestures such as pinch-to-zoom, and a new web browser based on the same WebKit rendering engine used by the iPhone. The following year, RIM released BlackBerry OS 7 and new models in the Bold and Torch ranges, which included a new Bold with a touchscreen alongside its keyboard, and the Torch 9860—the first BlackBerry phone to not include a physical keyboard. In 2013, it replaced

2033-467: A replaceable battery, and a separate touch-screen color LCD below the main electronic paper reading screen. In 2017, Sony and reMarkable offered e-books tailored for writing with a smart stylus . In 2020, Onyx released the first frontlit 13.3 inch electronic paper Android tablet, the Boox Max Lumi. At the end of the same year, Bigme released the first 10.3 inch color electronic paper Android tablet,

2140-416: A rotary knob ring around the lens and a tripod mount. While screen sizes have increased, manufacturers have attempted to make smartphones thinner at the expense of utility and sturdiness, since a thinner frame is more vulnerable to bending and has less space for components, namely battery capacity. The iPhone and later touchscreen-only Android devices together popularized the slate form factor , based on

2247-456: A technology suited to digital signage applications. Typically, e-paper electronic tags integrate e-ink technology with wireless interfaces like NFC or UHF . They are most commonly used as employees' ID cards or as production labels to track manufacturing changes and status.

2354-433: A thin colored optical filter added to the monochrome technology described above. The array of pixels is divided into triads , typically consisting of the standard cyan, magenta and yellow, in the same way as CRT monitors (although using subtractive primary colors as opposed to additive primary colors). The display is then controlled like any other electronic color display. E Ink Corporation of E Ink Holdings Inc. released

2461-457: A transparent silicone sheet, with each sphere suspended in a bubble of oil so that it can rotate freely. The polarity of the voltage applied to each pair of electrodes then determines whether the white or black side is face-up, thus giving the pixel a white or black appearance. At the FPD 2008 exhibition, Japanese company Soken demonstrated a wall with electronic wall-paper using this technology. In 2007,

2568-579: A variety of wireless communication standards, including LTE , 5G NR , Wi-Fi , Bluetooth , and satellite navigation . By the mid-2020s, manufacturers began integrating satellite messaging and emergency services, expanding their utility in remote areas without reliable cellular coverage . Following the rising popularity of the iPhone in the late 2000s, the majority of smartphones have featured thin, slate-like form factors with large, capacitive touch screens with support for multi-touch gestures rather than physical keyboards. Most modern smartphones have

2675-571: A version of Apple's Safari browser that could render full websites not specifically designed for mobile phones. Later Apple shipped a software update that gave the iPhone a built-in on-device App Store allowing direct wireless downloads of third-party software. This kind of centralized App Store and free developer tools quickly became the new main paradigm for all smartphone platforms for software development , distribution , discovery, installation , and payment, in place of expensive developer tools that required official approval to use and

2782-520: Is a display device that reflects ambient light, mimicking the appearance of ordinary ink on paper – unlike conventional flat-panel displays which need additional energy to emit their own light. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without

2889-410: Is a highly reflective metasurface made by metal-insulator-metal films tens of nanometers in thickness including nanoscale holes. The metasurfaces can reflect different colors depending on the thickness of the insulator. The standard RGB color schema can be used as pixels for full-color displays.

Smartphones are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems , access to

3103-491: Is batteryless design. This means that the power needed for a display's content update is provided wirelessly and the module itself doesn't contain any battery. Other proposed applications include clothes, digital photo frames, information boards, and keyboards. Keyboards with dynamically changeable keys are useful for less represented languages, non-standard keyboard layouts such as Dvorak , or for special non-alphabetical applications such as video editing or games. The reMarkable

3210-572: Is fast enough to display video content. It is a low-power, low-voltage technology, and displays based on the effect can be made flat and thin. The reflectivity and contrast are better than or equal to other reflective display types and approach the visual qualities of paper. In addition, the technology offers a unique path toward high-brightness full-color displays, leading to displays that are four times brighter than reflective LCDs and twice as bright as other emerging technologies. Instead of using red, green, and blue (RGB) filters or alternating segments of

3317-400: Is more similar to LCD but does not need power to retain an image. E-paper displays at bus or trams stops can be remotely updated. Compared to LED or liquid-crystal displays (LCDs), they consume lower energy and the text or graphics stays visible during a power failure. Compared to LCDs, it easily visible under full sunshine. Because of its energy-saving properties, electronic paper has proved

3424-533: Is naturally white. The screen holds microcapsules in a layer of liquid polymer , sandwiched between two arrays of electrodes, the upper of which is transparent. The two arrays are aligned to divide the sheet into pixels, and each pixel corresponds to a pair of electrodes situated on either side of the sheet. The sheet is laminated with transparent plastic for protection, resulting in an overall thickness of 80 micrometers, or twice that of ordinary paper. The network of electrodes connects to display circuitry, which turns

3531-458: Is no longer stable, causing the water to move the oil aside. This makes a partly transparent pixel, or, if a reflective white surface is under the switchable element, a white pixel. Because of the small pixel size, the user only experiences the average reflection, which provides a high-brightness, high-contrast switchable element. Displays based on electrowetting provide several attractive features. The switching between white and colored reflection

3638-613: Is now part of E Ink Corporation. The SiPix design uses a flexible 0.15 mm Microcup architecture, instead of E Ink's 0.04 mm diameter microcapsules. Bridgestone Corp.'s Advanced Materials Division cooperated with Delta Optoelectronics Inc. in developing Quick Response Liquid Powder Display technology. Electrophoretic displays can be manufactured using the Electronics on Plastic by Laser Release (EPLaR) process, developed by Philips Research , to enable existing AM-LCD manufacturing plants to create flexible plastic displays. In

3745-428: Is used on computer monitors like the 13.3 inch Dasung Paperlike 3 HD and 25.3 inch Paperlike 253. Some laptops like Lenovo ThinkBook Plus use e-paper as a secondary screen.

Five billion camera phones were sold in five years, and by 2007 more than half of

3959-1028: The Japanese market , such as mobile payments and shopping, near-field communication (NFC) allowing mobile wallet functionality to replace smart cards for transit fares, loyalty cards, identity cards, event tickets, coupons, money transfer, etc., downloadable content like musical ringtones , games , and comics , and 1seg mobile television . Phones built by Japanese manufacturers used custom firmware , however, and did not yet feature standardized mobile operating systems designed to cater to third-party application development , so their software and ecosystems were akin to very advanced feature phones . As with other feature phones, additional software and services required partnerships and deals with providers. The degree of integration between phones and carriers, unique phone features, non-standardized platforms, and tailoring to Japanese culture made it difficult for Japanese manufacturers to export their phones, especially when demand

4066-580: The Nokia 9000 Communicator , a digital cellular PDA based on the Nokia 2110 with an integrated system based on the PEN/GEOS 3.0 operating system from Geoworks . The two components were attached by a hinge in what became known as a clamshell design , with the display above and a physical QWERTY keyboard below.

In addition, smartphones are equipped to support

4708-475: The " Pocket PC " versions of what was later Windows Mobile , and the UIQ interface that was originally designed for pen-based PDAs on Symbian OS devices resulted in some early smartphones having stylus-based interfaces. These allowed for virtual keyboards and handwriting input, thus also allowing easy entry of Asian characters. By the mid-2000s, the majority of smartphones had a physical QWERTY keyboard. Most used

4815-450: The 1990s another type of electronic ink based on a microencapsulated electrophoretic display was conceived and prototyped by a team of undergraduates at MIT as described in their Nature paper. J.D. Albert, Barrett Comiskey , Joseph Jacobson, Jeremy Rubin and Russ Wilcox co-founded E Ink Corporation in 1997 to commercialize the technology. E Ink subsequently formed a partnership with Philips Components two years later to develop and market

4922-495: The 1990s, or lithium-ion batteries used in modern smartphones. The term "smart phone" (in two words) was not coined until a year after the introduction of the Simon, appearing in print as early as 1995, describing AT&T's PhoneWriter Communicator. The term "smartphone" (as one word) was first used by Ericsson in 1997 to describe a new device concept, the GS88 . Beginning in

5029-514: The 2000s, NTT DoCoMo 's i-mode platform, BlackBerry , Nokia 's Symbian platform, and Windows Mobile began to gain market traction, with models often featuring QWERTY keyboards or resistive touchscreen input and emphasizing access to push email and wireless internet . In the early 1990s, IBM engineer Frank Canova realised that chip-and-wireless technology was becoming small enough to use in handheld devices . The first commercially available device that could be properly referred to as

5136-532: The Bigme B1 Pro. This was also the first large electronic paper tablet to support 4g cellular data. In February 2006, the Flemish daily De Tijd distributed an electronic version of the paper to select subscribers in a limited marketing study, using a pre-release version of the iRex iLiad . This was the first recorded application of electronic ink to newspaper publishing. The French daily Les Échos announced

5243-546: The Estonian company Visitret Displays was developing this kind of display using polyvinylidene fluoride (PVDF) as the material for the spheres, dramatically improving the video speed and decreasing the control voltage needed. An electrophoretic display ( EPD ) forms images by rearranging charged pigment particles with an applied electric field .

Since

5778-533: The appropriate voltage to each region of the display to create a pattern of reflecting and absorbing regions. EPDs are typically addressed using MOSFET -based thin-film transistor (TFT) technology. TFTs are often used to form a high-density image in an EPD. A common application for TFT-based EPDs are e-readers. Electrophoretic displays are considered prime examples of the electronic paper category, because of their paper-like appearance and low power consumption. Examples of commercial electrophoretic displays include

5885-635: The base requires a thin, flexible material tough enough to withstand considerable wear, such as extremely thin plastic. The method of how the inks are encapsulated and then applied to the substrate is what distinguishes each company from others. These processes are complex and are carefully guarded industry secrets. Nevertheless, making electronic paper is less complex and costly than LCDs. There are many approaches to electronic paper, with many companies developing technology in this area. Other technologies being applied to electronic paper include modifications of liquid-crystal displays , electrochromic displays, and

5992-601: The bottom of the capsule (so the viewer saw the color of the oil). This was essentially a reintroduction of the well-known electrophoretic display technology, but microcapsules meant the display could be made on flexible plastic sheets instead of glass. One early version of the electronic paper consists of a sheet of very small transparent capsules, each about 40 micrometers across. Each capsule contains an oily solution containing black dye (the electronic ink), with numerous white titanium dioxide particles suspended within. The particles are slightly negatively charged , and each one

6099-483: The company announced that it would also exit the hardware market to focus more on software and its enterprise middleware, and began to license the BlackBerry brand and its Android distribution to third-party OEMs such as TCL for future devices.

6634-416: The electromigration of highly scattering or absorbing microparticles (in the size range 0.1–5 μm), quite distinct from the molecular-scale properties that govern the behavior of the more familiar liquid-crystal displays. Micro-particle-based displays possess intrinsic bistability, exhibit extremely low power d.c. field addressing and have demonstrated high contrast and reflectivity. These features, combined with

6741-476: The electronic equivalent of an Etch A Sketch at Kyushu University. Advantages of electronic paper include low power usage (power is only drawn when the display is updated), flexibility and better readability than most displays. Electronic ink can be printed on any surface, including walls, billboards, product labels and T-shirts. The ink's flexibility would also make it possible to develop rollable displays for electronic devices. In December 2005, Seiko released

6848-469: The electronic ink 'on' and 'off' at specific pixels by applying a voltage to specific electrode pairs. A negative charge to the surface electrode repels the particles to the bottom of local capsules, forcing the black dye to the surface and turning the pixel black. Reversing the voltage has the opposite effect. It forces the particles to the surface, turning the pixel white. A more recent implementation of this concept requires only one layer of electrodes beneath

6955-471: The first "YotaPhone" prototype and was later released in December 2013, a unique double-display smartphone. It has a 4.3-inch, HD LCD on the front and an electronic ink display on the back. On May and June 2020, Hisense released the Hisense A5c and A5 pro cc, the first color electronic ink smartphones.

The Pebble smart watch (2013) uses a low-power memory LCD manufactured by Sharp for its e-paper display. In 2019, Fossil launched a hybrid smartwatch called

7276-600: The functionality of standalone PDA devices with support for cellular telephony , but were limited by their bulky form, short battery life , slow analog cellular networks, and the immaturity of wireless data services. These issues were eventually resolved with the exponential scaling and miniaturization of MOS transistors down to sub-micron levels ( Moore's law ), the improved lithium-ion battery , faster digital mobile data networks ( Edholm's law ), and more mature software platforms that allowed mobile device ecosystems to develop independently of data providers . In

7383-485: The high-resolution active matrix displays used in the Amazon Kindle , Barnes & Noble Nook , Sony Reader , Kobo eReader , and iRex iLiad e-readers. These displays are constructed from an electrophoretic imaging film manufactured by E Ink Corporation . A mobile phone that used the technology is the Motorola Fone . Electrophoretic Display technology has also been developed by SiPix and Bridgestone /Delta. SiPix

7490-466: The iPhone; Palm unveiled a new platform known as webOS for its Palm Pre in late-2009 to replace Palm OS , which featured a focus on a task-based "card" metaphor and seamless synchronization and integration between various online services (as opposed to the then-conventional concept of a smartphone needing a PC to serve as a "canonical, authoritative repository" for user data). HP acquired Palm in 2010 and released several other webOS devices, including

7597-582: The image appearing to fade. Technologies include Gyricon , electrophoretics , electrowetting , interferometry , and plasmonics . Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane.

Electronic paper

7704-447: The image on the electronic paper has been set, it requires no power to maintain, so the readout can be seen even when the flash drive is not plugged in. E-paper based electronic shelf labels (ESL) are used to digitally display the prices of goods at retail stores. Electronic-paper-based labels are updated via two-way infrared or radio technology and powered by a rechargeable coin cell. Some variants use ZBD (zenithal bistable display) which

7811-526: The increasing use of smartphones with rapidly improving camera technology for casual photography, easier image manipulation , and abilities to directly share photos through the use of apps and web-based services. By 2011, cell phones with integrated cameras were selling hundreds of millions per year. In 2015, digital camera sales were 35.395 million units or only less than a third of digital camera sales numbers at their peak and also slightly less than film camera sold number at their peak. Contributing to

7918-533: The legacy BlackBerry OS with a revamped, QNX -based platform known as BlackBerry 10 , with the all-touch BlackBerry Z10 and keyboard-equipped Q10 as launch devices. In 2010, Microsoft unveiled a replacement for Windows Mobile known as Windows Phone , featuring a new touchscreen-centric user interface built around flat design and typography, a home screen with "live tiles" containing feeds of updates from apps, as well as integrated Microsoft Office apps. In February 2011, Nokia announced that it had entered into

8025-535: The main image with a macro focus shot . In 2007 the Nokia N95 was notable as a smartphone that had a 5.0 Megapixel (MP) camera, when most others had cameras with around 3 MP or less than 2 MP. Some specialized feature phones like the LG Viewty , Samsung SGH-G800 , and Sony Ericsson K850i , all released later that year, also had 5.0 MP cameras. By 2010 5.0 MP cameras were common; a few smartphones had 8.0 MP cameras and

8132-400: The microcapsules. These are commercially referred to as Active Matrix Electrophoretic Displays (AMEPD). This technology is similar to common LCD while the backlight panel is substituted by a reflective surface. A comparable technology is also obtainable in backlight LCDs by software or hardware deactivating the backlight control. Electrowetting display ( EWD ) is based on controlling

8239-526: The mid-to-late 1990s, many people who had mobile phones carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS , Newton OS , Symbian or Windows CE / Pocket PC . These operating systems would later evolve into early mobile operating systems . Most of the "smartphones" in this era were hybrid devices that combined these existing familiar PDA OSes with basic phone hardware. The results were devices that were bulkier than either dedicated mobile phones or PDAs, but allowed

8346-517: The official launch of an electronic version of the paper on a subscription basis in September 2007. Two offers were available, combining a one-year subscription and a reading device. The offer included either a light (176g) reading device (adapted for Les Echos by Ganaxa) or the iRex iLiad . Two different processing platforms were used to deliver readable information of the daily, one based on the newly developed GPP electronic ink platform from Ganaxa , and

8453-631: The optically active layer can be less than 15 micrometres thick, there is strong potential for rollable displays . The technology used in electronic visual displays that can create various colors via interference of reflected light. The color is selected with an electrically switched light modulator comprising a microscopic cavity that is switched on and off using driver integrated circuits similar to those used to address liquid-crystal displays (LCD). Plasmonic nanostructures with conductive polymers have also been suggested as one kind of electronic paper. The material has two parts. The first part

8560-612: The other one developed internally by Les Echos. Flexible display cards enable financial payment cardholders to generate a one-time password to reduce online banking and transaction fraud. Electronic paper offers a flat and thin alternative to existing key fob tokens for data security. The world's first ISO compliant smart card with an embedded display was developed by Innovative Card Technologies and nCryptone in 2005. The cards were manufactured by Nagra ID. Some devices, like USB flash drives , have used electronic paper to display status information, such as available storage space. Once

8667-532: The particles evenly distributed across the panel. The liquid is formulated so that the floating particles can be pulled through it in response to the magnetic forces , but not due to gravity . Because the Magna Doodle uses no ink or graphite , it is used by scuba divers as an underwater whiteboard when instructing students, and by divers who wish to pass short notes. The Magna Doodle is not specifically designed to work underwater and many of its components can rust or otherwise deteriorate over time. The toy

8774-451: The particles. When the particles are located at the front (viewing) side of the display, it appears white, because the light is scattered back to the viewer by the high-index titania particles. When the particles are located at the rear side of the display, it appears dark, because the light is absorbed by the colored dye. If the rear electrode is divided into a number of small picture elements ( pixels ), then an image can be formed by applying

8881-403: The plans for any e-reader devices. Several companies are simultaneously developing electronic paper and ink. While the technologies used by each company provide many of the same features, each has its own distinct technological advantages. All electronic paper technologies face the following general challenges: Electronic ink can be applied to flexible or rigid materials. For flexible displays,

8988-671: The platform such as online shopping. NTT DoCoMo's i-mode used cHTML , a language which restricted some aspects of traditional HTML in favor of increasing data speed for the devices. Limited functionality, small screens and limited bandwidth allowed for phones to use the slower data speeds available. The rise of i-mode helped NTT DoCoMo accumulate an estimated 40 million subscribers by the end of 2001, and ranked first in market capitalization in Japan and second globally. Japanese cell phones increasingly diverged from global standards and trends to offer other forms of advanced services and smartphone-like functionality that were specifically tailored to

9095-447: The polymer on the plasmonic metasurfaces, the reflection of the metasurfaces can be modulated by the applied voltage. This technology presents broad range colors, high polarization-independent reflection (>50 %), strong contrast (>30 %), the fast response time (hundreds of ms), and long-term stability. In addition, it has ultralow power consumption (< 0.5 mW/cm2) and potential for high resolution (>10000 dpi). Since

9202-530: The price of the panels, Mattel ended the licence agreement in 2003, but then began selling a new product called the Doodle Pro which used third-party panels and similar packaging. This led to Pilot suing Mattel unsuccessfully in 2004 for infringement of its trademark and trade dress , while relicensing the brand to the Ohio Art Company . Ohio Art, in turn, eventually dropped the license as well, later producing

9309-570: The reservoir. The technology can potentially provide greater than 85% white state reflectance for electronic paper. The core technology was invented at the Novel Devices Laboratory at the University of Cincinnati and there are working prototypes developed by collaboration with Sun Chemical , Polymer Vision and Gamma Dynamics. It has a wide margin in critical aspects such as brightness , color saturation and response time . Because

9416-518: The rest of the world. Phones that made effective use of any significant data connectivity were still rare outside Japan until the introduction of the Danger Hiptop in 2002, which saw moderate success among U.S. consumers as the T-Mobile Sidekick. Later, in the mid-2000s, business users in the U.S. started to adopt devices based on Microsoft's Windows Mobile , and then BlackBerry smartphones from Research In Motion . American users popularized

9523-412: The rise in popularity of smartphones being used over dedicated cameras for photography, smaller pocket cameras have difficulty producing bokeh in images, but nowadays, some smartphones have dual-lens cameras that reproduce the bokeh effect easily, and can even rearrange the level of bokeh after shooting. This works by capturing multiple images with different focus settings, then combining the background of

9630-408: The shape of a confined water/oil interface by an applied voltage. With no voltage applied, the (colored) oil forms a flat film between the water and a hydrophobic (water-repellent) insulating coating of an electrode, resulting in a colored pixel. When a voltage is applied between the electrode and the water, the interfacial tension between the water and the coating changes. As a result, the stacked state

9737-560: The similar Doodle Sketch until 2016 when it sold that brand along with Etch A Sketch to Spin Master . The current licensee of the Magna Doodle brand is Cra-Z-Art. In the TV comedy Friends , a Magna Doodle is visible in Joey and Chandler's apartment, with various messages written on it throughout the series, referencing plot points, current events, inside crew jokes, or just random drawings. A version of

9844-555: The standalone handset can when necessary be inserted into a tablet -sized screen unit with integrated supportive battery and used as such. In 2013 and 2014, Samsung experimented with the hybrid combination of compact camera and smartphone, releasing the Galaxy S4 Zoom and K Zoom , each equipped with integrated 10× optical zoom lens and manual parameter settings (including manual exposure and focus) years before these were widely adapted among smartphones. The S4 Zoom additionally has

9951-542: The task key to simulate a short menu key press, as with home button to search. More recent "bezel-less" types have their screen surface space extended to the unit's front bottom to compensate for the display area lost for simulating the navigation keys. While virtual keys offer more potential customizability, their location may be inconsistent among systems depending on screen rotation and software used. Multiple vendors attempted to update or replace their existing smartphone platforms and devices to better-compete with Android and

10058-411: The technology. In 2005, Philips sold the electronic paper business as well as its related patents to Prime View International . "It has for many years been an ambition of researchers in display media to create a flexible low-cost system that is the electronic analog of paper. In this context, microparticle-based displays have long intrigued researchers. Switchable contrast in such displays is achieved by

10165-467: The term "CrackBerry" in 2006 due to the BlackBerry's addictive nature. In the U.S., the high cost of data plans and relative rarity of devices with Wi-Fi capabilities that could avoid cellular data network usage kept adoption of smartphones mainly to business professionals and " early adopters ." Outside the U.S. and Japan, Nokia was seeing success with its smartphones based on Symbian , originally developed by Psion for their personal organisers, and it

10272-445: The three primary colors, which effectively result in only one-third of the display reflecting light in the desired color, electrowetting allows for a system in which one sub-pixel can switch two different colors independently. This results in the availability of two-thirds of the display area to reflect light in any desired color. This is achieved by building up a pixel with a stack of two independently controllable colored oil films plus

10379-432: The time that a touchscreen could not completely replace a physical keyboard and buttons. Android is based around a modified Linux kernel, again providing more power than mobile operating systems adapted from PDAs and feature phones. The first Android device, the horizontal-sliding HTC Dream , was released in September 2008. In 2012, Asus started experimenting with a convertible docking system named PadFone , where

10486-429: The ultrathin metasurfaces are flexible and the polymer is soft, the whole system can be bent. Desired future improvements for this technology include bistability, cheaper materials and implementation with TFT arrays. Other research efforts into e-paper have involved using organic transistors embedded into flexible substrates , including attempts to build them into conventional paper. Simple color e-paper consists of

10593-439: The viewable pixel area and therefore the pigment is substantially hidden from view. Voltage is used to electromechanically pull the pigment out of the reservoir and spread it as a film directly behind the viewing substrate. As a result, the display takes on color and brightness similar to that of conventional pigments printed on paper. When voltage is removed liquid surface tension causes the pigment dispersion to rapidly recoil into

10700-603: Was announced in September 2011 that was the Kindle's first departure from keyboards and page turn buttons in favor of touchscreens. In September 2012, Amazon announced the fifth generation of the Kindle called the Paperwhite, which incorporates a LED frontlight and a higher contrast display. In November 2009, Barnes and Noble launched the Barnes & Noble Nook , running an Android operating system. It differs from other e-readers in having

10807-413: Was first developed in the 1970s by Nick Sheridon at Xerox 's Palo Alto Research Center . The first electronic paper, called Gyricon , consisted of polyethylene spheres between 75 and 106 micrometers across. Each sphere is a Janus particle composed of negatively charged black plastic on one side and positively charged white plastic on the other (each bead is thus a dipole ). The spheres are embedded in

10914-401: Was manufactured by Mitsubishi Electric , which integrated features with its own cellular radio technologies. It featured a liquid-crystal display (LCD) and PC Card support. The Simon was commercially unsuccessful, particularly due to its bulky form factor and limited battery life , using NiCad batteries rather than the nickel–metal hydride batteries commonly used in mobile phones in

11021-402: Was originally invented at Pilot Corporation , which registered "Magna Doodle" as a trademark in the U.S. in 1986, and has owned the underlying rights to the brand ever since. Magna Doodle toys were produced under license by Tyco , using panels produced by Pilot, until 1997, when Tyco was purchased by Mattel . Mattel then sold the toy under its Fisher-Price brand. Following a dispute over

11128-536: Was so high in Japan that the companies did not feel the need to look elsewhere for additional profits. The rise of 3G technology in other markets and non-Japanese phones with powerful standardized smartphone operating systems , app stores , and advanced wireless network capabilities allowed non-Japanese phone manufacturers to finally break in to the Japanese market, gradually adopting Japanese phone features like emojis , mobile payments, NFC, etc. and spreading them to

11235-710: Was succeeded by Satya Nadella (who has placed a larger focus on software and cloud computing) as CEO of Microsoft, it took a $ 7.6 billion write-off on the Nokia assets in July 2015, and laid off nearly the entire Microsoft Mobile unit in May 2016. Prior to the completion of the sale to Microsoft, Nokia released a series of Android-derived smartphones for emerging markets known as Nokia X , which combined an Android-based platform with elements of Windows Phone and Nokia's feature phone platform Asha , using Microsoft and Nokia services rather than Google. The first commercial camera phone

11342-471: Was the Kyocera Visual Phone VP-210 , released in Japan in May 1999. It was called a "mobile videophone" at the time, and had a 110,000- pixel front-facing camera . It could send up to two images per second over Japan's Personal Handy-phone System (PHS) cellular network , and store up to 20 JPEG digital images , which could be sent over e-mail . The first mass-market camera phone was

11449-646: Was the most popular smartphone OS in Europe during the middle to late 2000s. Initially, Nokia's Symbian smartphones were focused on business with the Eseries , similar to Windows Mobile and BlackBerry devices at the time. From 2002 onwards, Nokia started producing consumer-focused smartphones, popularized by the entertainment-focused Nseries . Until 2010, Symbian was the world's most widely used smartphone operating system. The touchscreen personal digital assistant (PDA)–derived nature of adapted operating systems like Palm OS ,
