The HTC Touch Diamond2 , a mobile phone designed by the HTC Corporation , is the successor to the popular HTC Touch Diamond . It is also known by its codename , the HTC Topaz . It is released with Microsoft Windows Mobile 6.1 , but can be upgraded to Windows Mobile 6.5 . It is the first device to feature a revamped version of HTC's TouchFLO 3D GUI, an interface first seen on its predecessor. The Touch Diamond2 has been announced to be released in Q2 2009 and was first announced at the Mobile World Congress 2009 in Barcelona .
10-585: An AT&T-branded version known as the HTC Pure was released in the U.S. on October 6, 2009. The Pure was released with Windows Mobile 6.5, and featured a redesign of the phone, with a more uniform glossy black surface, and a rounded bottom. The unlocked version went on sale in the UK on April 15, 2009, and in Singapore on April 16. The XDAndroid project makes it possible to run Android on HTC Windows Mobile phones, including
20-577: A few milliseconds, registering the exact touch location as contact is made, provided the screen has been properly calibrated for variations in resistivity. Resistive touchscreens can have high resolution (4096 x 4096 or higher), providing accurate touch control. Because the touchscreen responds to pressure on its surface, contact can be made with a finger or any other pointing device. Resistive touchscreen technology works well with almost any stylus -like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this
30-411: A four-wire touchscreen, a uniform, unidirectional voltage gradient is applied to the first sheet. When the two sheets are pressed together, the second sheet measures the voltage as distance along with the first sheet, providing the X coordinate. When this contact coordinate has been acquired, the voltage gradient is applied to the second sheet to ascertain the Y coordinate. These operations occur within
40-452: A light sensor for automatic backlight adjustment. HTC opted out, however, of including a proximity sensor , a feature prominently featured on their enterprise flagship device, the Touch Pro2. Resistive touchscreen A resistive touchscreen is a type of touch-sensitive display that works by detecting pressure applied to the screen. It is composed of two flexible sheets coated with
50-425: A resistive material and separated by an air gap or microdots. There are two different types of metallic layers. The first type is called matrix , in which striped electrodes on substrates such as glass or plastic face each other. The second type is called analogue which consists of transparent electrodes without any patterning facing each other. As of 2011 analogue offered lowered production costs. When contact
60-410: Is made to the surface of the touchscreen, the two sheets are pressed together. On these two sheets there are horizontal and vertical lines that, when pushed together, register the precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touchscreens are a type of "passive" technology. For example, during the operation of
70-679: Is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens). A resistive touchscreen operated with a stylus will generally offer greater pointing precision than a capacitive touchscreen operated with a finger. Costs are relatively low when compared with active touchscreen technologies, but are also more prone to damage. Resistive touchscreen technology can be made to support multi-touch input. Single-touch screens register multiple touch inputs in their balanced location and pressure levels. For people who must grip
80-578: The Touch Diamond2. The Touch Diamond2 utilizes a 3.2" wide resistive touchscreen , with a resistive zoom bar below the screen to replace the larger capacitive area and navigational pad found on the HTC Diamond and Touch Pro. This device, although thicker than its predecessor (13.7 millimetres (0.54 in) thick), now features a significantly larger screen with a better resolution ( WVGA rather than VGA ). Touch Diamond users complained that battery life
90-586: The active portion of the screen or must set their entire hand down on the screen, alternative touchscreen technologies are available, such as an active touchscreen in which only the stylus creates input and skin touches are rejected. However, newer touchscreen technologies allow the use of multi-touch without the aforementioned vectoring issues. Where conditions allow bare finger operation, the resistive screen's poorer responsiveness to light touches has caused it to generally be considered for use with low resolution screens and to lose market share to capacitive screens in
100-429: Was quite poor. At MWC 2009, HTC CEO Peter Chou announced the Touch Diamond2 would have 50% better battery life. The camera has been upped from 3.2 megapixels to 5 megapixels. The device also includes expandable memory, meaning users are able to insert their own microSD cards, rather than relying on internal storage only, as with the original Diamond. HTC has again included an accelerometer for screen rotation detection and
