Abstract

According to the LED display circuit and the LED display screen, when a video signal is received through a control circuit, a display signal and a display data compensation signal are output according to the video signal; the video encoding and decoding circuit decodes the display signal into a plurality of groups of sub display signals and outputs the sub display signals; the plurality of display modules display according to the power supply voltage and the sub display signals; the sub-display signals are input to the display modules in a one-to-one correspondence manner; the compensation circuit compensates the power of the power supply voltage according to the display data compensation signal; the display data compensation signal is generated according to the video signal, and the compensation circuit compensates the power of the power supply voltage according to the display data compensation signal, so that the fluctuation of the power of the power supply voltage is reduced, and electromagnetic radiation is reduced.

Description

technical field [0001] The present application belongs to the field of display equipment, and in particular relates to an LED display circuit and an LED display screen. Background technique [0002] The traditional LED display circuit includes a control circuit, a video codec circuit, and multiple display modules; when the control circuit receives a video signal, it outputs a display signal according to the video signal; the video codec circuit outputs multiple groups of sub-display signals according to the display signal; A display module displays according to the power supply voltage and sub-display signals; since the LED display circuit is driven by current, the current and power consumption fluctuate violently as the pattern changes, and the changing current will generate a fluctuating magnetic field, which will cause the entire The device works in a fluctuating electromagnetic environment. The electronics industry has higher and higher requirements for electromagnetic ...
