1, the OLED screen can directly control the pixels, so it can directly turn off the light emission of the pixels, so when displaying a pure black picture, it is pure black and will not leak light.

2. Organic light-emitting diodes are very thin because they don't need backlight, so the screen of organic light-emitting diodes is about one third of the thickness of LED screen, or even thinner.

3. Different panels

LED panel can't solve the problem of smear and afterimage, because it takes time for liquid crystal molecules to accept command changes, so the response time is usually very long, with a minimum of 2 ms

Because the organic light-emitting diode itself emits light, the speed of directly controlling pixels is very fast, and it is difficult to observe the afterimage phenomenon.
