What is the difference between oled and led screens?

The difference between OLED and LED screens: 1. OLED is the English abbreviation of organic light-emitting semiconductor, and LED is the English abbreviation of light-emitting diode; 2. Each pixel of OLED can emit monochromatic light, so there is no need for a light-emitting layer , the LED panel has a light-emitting layer; 3. OLED can directly turn off the light emission of pixels. LED cannot control all pixels. If you want to display black, liquid crystal molecules need to be used to block the light; 4. OLED screen is three-thirds of the thickness of the LED screen One or so, OLED can bend, LED can't and so on.

The difference between oled screen and led screen:

1. The names are different. LED is lightemittingdiode, the English abbreviation of light-emitting diode: OLED refers to OraanicLight-EmittinaDiode, the English abbreviation of organic light-emitting semiconductor.

2. The luminescence principle is different. The LED panel has a light-emitting layer, which is composed of multiple red light-emitting diodes. It uses the molecular deflection of the liquid crystal layer to display different images. Each pixel of the OLED can emit monochromatic light, so there is no need for a light-emitting layer and current can be passed directly. Driving organic thin films to emit light.

3. The contrast is different. LED cannot control all pixels, so if you want to display black, you have to block the light through liquid crystal molecules. Therefore, some light will always leak out, causing the TV to turn gray when displaying a pure black screen. problem, but because OLED screens can directly control pixels, they can directly turn off the luminescence of pixels.

4. The structure and screen thickness are different. The structure of the LED screen is relatively complex and consists of several layers. However, OLED does not require backlight, so it is very thin. Therefore, the OLED screen is about one-third the thickness of the LED screen, or even thinner. The OLED panel also has a bendable Features, this is something that LED panels cannot achieve at all.

5. The display effects are different. LED screens can generally achieve NTSC72% color gamut, while OLED's colors are more conspicuous and can reach NTSC100%, which can meet the needs of the current more demanding color gamuts such as BT2020, but there may be problems with color temperature and color cast

6The service life is different. There is no screen burn-in in LED screens. OLED screens are prone to screen burn-in after being used for a long time. LEDs have more advantages in terms of service life

7. The use experience is different. Generally speaking, the sensory experience of OLED screens is better than that of LED screens.
