Principle of grayscale imaging

The gray level of the High definition led screen mainly depends on the digital to analog conversion number of the system. Of course, the video processing chip, memory and transmission system of the system must provide the corresponding digit support. At present, led display screen mainly adopts:

An 8-bit processing system, that is, 256 (2 to the eighth power) level of grayscale. The simple idea is that there are 256 variations in brightness from black to white.

Two, 10-bit processing system, that is, 1024 (2 to the tenth power) level gray. The simple idea is that there are 1024 variations from black to white.

Three, 12-bit processing system, that is, 4096 (2 to the 12th power) level grayscale. Simply put, there are 4,096 variations from black to white.
