The difference between OLED and LED
OLED: OrganicLightEmitTIngDisplay, that is, organic light-emitting display, which is a newly emerging category on mobile phone LCD, is known as "dream display". The OLED display technology is different from the traditional LCD display method. No backlight is needed, and a very thin organic material coating and glass substrate are used. When an electric current passes through, these organic materials will emit light. And the OLED display screen can be made lighter and thinner, the viewing angle is larger, and can significantly save power. However, although more advanced OLEDs will replace LCDs such as TFTs in the future, organic light-emitting display technology still has shortcomings such as short service life and difficulty in increasing the screen size.
LED is the abbreviation of LightEmitTIngDiode.
LED applications can be divided into two categories: one is LED single-tube applications, including backlight LEDs, infrared LEDs, etc .; the other is LED display screens. At present, there is still a certain gap between China and the international in the manufacture of LED basic materials, but As far as LED displays are concerned, China's design and production technology levels are basically in sync with international standards.
The LED display screen is a display device composed of light-emitting diodes arranged. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, few failures, large viewing angle and long viewing distance.
