abstract:-
Lighting efficiency
Incandescent bulbs are inefficient
Fluorescent bulbs give off ugly light
LEDs (ordinary light emitting diodes) are bright points; not versatile
OLEDs may be better on all counts
Displays: Significant advantages over liquid crystals
Faster
Brighter
Lower power
Cost and design
LEDs are crystals; LCDs are highly structured; OLEDs are not –
Malleable; can be bent, rolled up, etc.
Easier to fabricate
In general, OLED research proceeds on many fronts
