when did the first oled tv come out
OLED DuPont stated in a press release in May 2010 that they can produce a 50-inch OLED TV in two minutes with a new printing technology. If this can be scaled up in terms of manufacturing, then the total cost of OLED TVs would be greatly reduced. DuPont also states that OLED TVs made with this less expensive technology can last up to 15 years if left on for a normal eight-hour day.[104][105]
Television in India In January 1950, The Indian Express reported that a television was put up for demonstration at an exhibition in the Teynampet locality of Madras (now Chennai) by B. Sivakumaran, a student of electrical engineering. A letter was scanned and its image displayed on a cathode ray tube screen. The report said that "[i]t may be this is not the whole of television but it is certainly the most significant link in the system" and added that the demonstration of the sort could be the "first in India".[5]
