Abstract

The present application discloses a liquid crystal display common voltage control method, circuit, equipment and medium, wherein the liquid crystal display common voltage control method includes first obtaining the current environmental parameters of the liquid crystal display, and then determining the The target voltage value at the common electrode of each pixel in the liquid crystal display screen, and then adjust the voltage of the common electrode of each pixel according to the target voltage value. Thus, the flickering of the display screen due to the influence of the environment is avoided, not only the performance of the display screen is improved, but also the damage to the user is reduced, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a liquid crystal display common voltage control method, circuit, equipment and medium. Background technique [0002] Two sheets of polarized material are used in an LCD, with a liquid crystal solution between them. Passing an electric current through the liquid rearranges the crystals to allow light to pass through them, creating an image. Each crystal acts like a shutter, allowing light to pass through and blocking it. [0003] Thin-film transistor liquid crystal display is a display that uses transistors to generate voltage to control the direction of liquid crystal. When working specifically, the gate (Gate) drive circuit sequentially drives the transistors in each row of pixels to turn on, and then the source (Source) drive circuit provides the pixel electrode voltage for the pixels of the same row, and each liquid crystal molecule The difference between the ...
