OLED vs LCD in Video Glasses


With OLED (organic light emitting diode), a stack of organic polymers, including both emissive and conductive layers, is deposited on a substrate containing a thin-film transistor (TFT) array. An electrical charge passing between the bottom electrodes and an additional transparent layer on the surface of the display stimulates the emissive organic layer, which in turn creates light.

Like LCD, OLED requires no backlight or projection lamp. But unlike most LCD 's we've seen to date, an OLED doesn't need to keep its pixel cells partially fired up at all times to be ready to respond to the signal. That's because OLED cells respond so quickly, they can be fully turned off until needed. Signal response time in an OLED is measured in microseconds (a far cry from the several millisecond response times in today's LCDs). Bottom ...
