The same is the self-illuminating display, then the difference between the LED display and the OLED display.

The LED display is a display device composed of an array of light emitting diodes. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, less failure, large viewing angle and long visible distance.

The OLED display, the organic light-emitting display, is a newly emerging category on the mobile phone LCD and is known as the “dream display”. OLED display technology is different from traditional LCD display methods. It does not require a backlight. It uses a very thin coating of organic materials and a glass substrate or a special plastic substrate. When there is current, these organic materials will emit light. Moreover, the OLED display screen can be made lighter and thinner, has a larger viewing angle, and can significantly save power. However, although OLEDs with better technology will replace LCDs such as TFTs in the future, organic light-emitting display technologies have shortcomings such as short lifetime and large screen size.
