In 1950 a more efficient 2 + 1 ⁄ 2 inch tube with vastly improved technology and more efficient white phosphor, along with smaller and less demanding screen sizes, was able to provide an acceptable image, though the life of the tubes was still shorter than contemporary direct view tubes. As CRT technology improved during the 1950s, producing larger and larger screen sizes and later on, (more or less) rectangular tubes,
2328-645: A smart phone or tablet. Hospitality spaces are insecure with respect to content piracy, so many content providers require the use of Digital rights management . Hospitality TVs decrypt the industry standard Pro:Idiom when no set back box is used. While H.264 is not part of the ATSC 1.0 standard in North America, TV content in hospitality can include H.264 encoded video, so hospitality TVs include H.264 decoding. Managing dozens or hundreds of TVs can be time consuming, so hospitality TVs can be cloned by storing settings on
2425-414: A television set in 1937 that relied on back projecting an image from a 4 + 1 ⁄ 2 inch tube onto a 25-inch screen. This required the tube to be driven very hard (at unusually high voltages and currents, see Cathode-ray tube § Projection CRTs ) to produce an extremely bright image on its fluorescent screen. Further, Philips decided to use a green phosphor on the tube face as it was brighter than

LCD TVs quickly displaced the only major competitors in the large-screen market, the plasma display panel and rear-projection television . In the mid-2010s LCDs became, by far, the most widely produced and sold television display type. LCDs also have disadvantages. Other technologies address these weaknesses, including OLEDs , FED and SED . LCDs can have quantum dots and mini-LED backlights to enhance image quality. An OLED (organic light-emitting diode)
7178-502: The functions of many transistors. Paul K. Weimer at RCA developed the thin-film transistor (TFT) in 1962, later the idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated the concept in 1968 with a dynamic scattering LCD that used standard discrete MOSFETs. In 1973, T. Peter Brody , J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories demonstrated
