In 2007, experimental OLEDs were created which can sustain 400 cd/m 2 of luminance for over 198,000 hours for green OLEDs and 62,000 hours for blue OLEDs. [136] In 2012, OLED lifetime to half of the initial brightness was improved to 900,000 hours for red, 1,450,000 hours for yellow and 400,000 hours for green at an initial luminance of 1,000 ...
A television set, also called a television receiver, television, TV set, TV, or telly, is a device that combines a tuner, display, and speakers for the purpose of viewing television.

Consequently, these systems were nicknamed "big dish" systems and were more expensive and less popular. [170]
Super AMOLED is a more advanced version and it integrates touch-sensors and the actual screen in a single layer. When compared with a regular LCD display an AMOLED display consumes less power, provides more vivid picture quality, and renders faster motion response as compared to other display technologies such as LCD.
Samsung and LG-Display showed 55-inch OLED-Television devices at CES-2012. But both companies had to delay their mass production. Also AUO, Sony and Epson will start AMOLED-TV production in 2014. [22] In June 2013 Samsung announced the Korean availability of a 55-inch curved OLED HDTV. Priced at 15 million Korean won (around $13,500).
Color LCDs based on Guest-Host interaction were invented by a team at RCA in 1968. [42] A particular type of such a color LCD was developed by Japan's Sharp Corporation in the 1970s, receiving patents for their inventions, such as a patent by Shinji Kato and Takaaki Miyazaki in May 1975, [ 43 ] and then improved by Fumiaki Funada and Masataka ...
The ubiquitous television set became the display device for the first recorded media for consumer use in the 1970s, such as Betamax, VHS; these were later succeeded by DVD. It has been used as a display device since the first generation of home computers (e.g. Timex Sinclair 1000) and dedicated video game consoles (e.g., Atari) in the 1980s.
