OLED HDTVOverviewWeve all seen them in Sci-Fi movies: newspapers being read on paper-thin TVs, mini-TVs in peoples clothing, TVs that curve around power poles. If these Sci-Fi visions are going to come true, then it will be accomplished by OLED(Organic Light Emitting Diode) technology. OLED works by having a positive (anode) layer and a negative (cathode) layer sandwiched between a light producing organic material. When electricity is applied between the cathode and anode, a small controlled current travels through the organic material. The current causes electrons to move from the organic material. These displaced electrons are replaced by “holes” (the opposite of an electron), with light being produced in this process. What color the light is depends on the type of organic material used. ![]()
Production UpdateSony currently has a 11" model out called the XEL-1 and plans on releasing a 27" version in 2009. Samsung plans on producing smaller OLED displays in 2009 and up to 42" in 2010. There is also speculation that Samsung will produce a flexible OLED display in 2010. Toshiba had plans on producing OLEDs in 2010, but decided to cancel them due to high production costs.Upside
