Samsung OLED Displays in 2003
Samsung SDI said this week that it expects to begin selling handheld-sized OLED screens by late 2003. They won't be selling them in notebook sizes until 2005.
The main advantages of OLED over current ones is the screen itself glows so there is no need for a back- or side-light. This means they require less power and take up less space, two important factors in a handheld. They also cost less to make.
Organic light emitting diodes (OLEDs) are made up of thin films of organic materials that give off light of various colors when voltage is applied to them.
They have many other advantages over LCDs, too. OLEDs have a faster response time so they are better able to show video. They can be seen from wider viewing angles. They are less susceptible to heat and cold. OLEDs have fewer manufacturing steps and use both fewer and cheaper materials than LCDs do.
Like LCDs, OLEDs have both active matrix and passive matrix forms. The first to be released are likely to be passive matrix, in which each pixel is an OLED and to make a particular pixel glow, current is applied to its row and column. In the active matrix version, each pixel is made of on OLED and a thin-film transistor. The TFT acts as a switch that controls how much power goes to the OLED.
OLED is a term for a whole group of possible screen types. FOLEDs are flexible and can be applied to curved surfaces like the insides of helmets. TOLEDs are 70% transparent when turned off and can be used on car windshields.
Research scientists at Kodak invented the OLED in the early 80s.
