OLED panels are made from organic materials that emit light when electricity is applied. Different from the LCD which needs backlight, the OLED does not need any backlight to display. Basically, the LCD does not emit light, it only “select ” the right color and intensity from the backlight and thus to display, while for OLED, each pixel of the OLED emits the light by themselves, the customer control all the pixels on/off and the intensity to show the images.
Compares to LCD, the OLED advantage is:
Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range and much faster refresh rates.
2. Lower power consumption
3. Simpler design that enables ultra-thin, flexible and transparent displays
4. Better durability - OLEDs are very durable and can operate in a broader temperature rangeOf course some drawbacks:
Lifespan, normally 5,000 hours, shorter than the LCD;
Color balance problems;
