Grayscale is the so-called gray scale, refers to the brightness of the degree of shade. For digitized display technology, grayscale is the determining factor in the number of colors. In general, the higher the grayscale, the richer the color is, the more delicate the picture, the more detailed the rich details.
The grayscale level depends primarily on the number of digital-to-analog conversion bits of the system. Of course, the system's video processing chip, memory and transmission systems must provide the corresponding number of bits of support. LED display currently used:
One, 8-bit processing system, that is, 256 (2 of the 8 power) level gray. Simple understanding is from black to white a total of 256 kinds of brightness changes.
Two, 10-bit processing system, that is, 1024 (2 10 power) level gray. Simple understanding is from black to white a total of 1024 kinds of brightness changes.
Three, 12-bit processing system, that is, 4096 (2 of the 12 power) level gray. Simple understanding is from the black to white a total of 4096 kinds of brightness changes.
Four, 14-bit processing system, that is, 16384 (2 of the 14th power) level gray. Simple understanding is from the black to white a total of 16384 kinds of brightness changes.
Grayscale is the determinant of left and right color, and the improvement of system processing digit will involve the change of system video processing, storage, transmission, scanning and so on. In general, private use of the display can be used 8-bit or 10-bit system, commercial or broadcast products can be used 12-bit system or even higher level system.
