LED display grayscale and brightness
The gray level of the LED display can also be called the brightness of the LED display. Gray scale is also called midtone, which is mainly used to transfer pictures. There are 16 levels, 32 levels and 64 levels respectively. It adopts a matrix processing method to process the pixels of files into levels of 16, 32, and 64 levels so that they can be transmitted. The picture is clearer. Whether it is a single-color, two-color, full-color LED display, to display an image or an animation requires adjusting the luminance of each LED constituting the pixel, and the fineness of its adjustment is what we commonly call gray scale.
The ED control system usually consists of three main parts: the main control box, the scan board, and the display and control unit. The main control box obtains the brightness data of each color of the one-screen pixel from the display card of the computer, and then re-assigns it to several scanning boards. Each scanning board is responsible for controlling several rows (columns) on the LED display screen, and each row (column) ) LED display control signal is transmitted in a serial manner.
LED display screen gray and brightness is one of the important parameters of the product, in order to better use the LED display, we need to understand the relationship between the LED display brightness and brightness.
