“It is based on “low-temperature polysilicon,” a technique also used in TFT-LCD production, where active components are integrated across the display glass. This lets the OLED display be made using modifications of existing techniques and production lines. Because OLED displays do not need a separate backlight, the power consumption of the finished unit should be lower than that of an LCD counterpart. “
We were able to see some smaller OLED display’s at the 2003 Consumer Electronics Show (CES). When comparing an OLED display to a regular TFT flat panel display, there were very clear differences. First of all, OLED displays do not use a transistor behind the pixels being shown, so there is a much deeper black and contrast ratio on the OLED display. Colors are also much brighter while the physical dimensions of the OLED display are much thinner.
