OLED uses organic compounds that illuminate when exposed to electric currents. So backlights aren't required for OLEDs, and hence they're significantly thinner than usual LCDs.
Popular variants of OLED include
Active-matrix OLED (AMOLED)
This type of display is found in modern high-end smart phones and are making progress toward low-power, low-cost and large-size applications. The key advantages of such displays are:
· High Perceived Luminance
· Contrast ratio
· Wide Viewing Angle
· True Colors
· Faster Response
One major disadvantage is the difficulty in viewing under direct sunlight.
A variant to the AMOLED display, this display addresses the issue of sun reflection. Other improvements include:
· Brighter screens
· Reduced power consumption
