OLED
THE SCIENCE
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.
STRENGTHS
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 ...
