Abstract

The invention belongs to the technical field of liquid crystal display, and specifically relates to a liquid crystal display module capable of adjusting display brightness. The liquid crystal display module comprises a backboard, a liquid crystal panel and an iron frame. The liquid crystal panel 2 internally comprises a pressure sensor, a photoresistor and a single chip microcomputer control chip. The pressure sensor and the photoresistor are connected with the single chip microcomputer control chip. The single chip microcomputer control chip is connected with a drive circuit in a main control panel. The single chip microcomputer control chip is also connected with a power supply. Through the design of adding the pressure sensor and the photoresistor, the function of automatically adjusting the display screen brightness is fulfilled. Through the design of adding fixing positions and clamping edges to a light guide plate, installation positioning is good and light guide is uniform during the liquid crystal display module assembly process. Accordingly, the liquid crystal display module capable of adjusting the display brightness has the function of automatically adjusting the display screen brightness, and has good application prospect and market value, the installation positioning is good, the light guide is uniform, and the design is scientific and simple.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal display module capable of adjusting display brightness. Background technique [0002] Liquid Crystal Display, known as LCD (Liquid Crystal Display) in English, is a kind of flat-panel display used for TV and computer screen display; LCD is a display used for digital clocks and many portable computers Type, LCD displays use two sheets of polarized material with a liquid crystal solution between them, passing an electric current through the liquid causes the crystals to rearrange so that light cannot pass through them. At present, the most commonly used liquid crystal displays are TFT-type liquid crystal displays, and TFT-type liquid crystal displays are relatively complex: the main components include fluorescent tubes, light guide plates, polarizers, filter plates, glass substrates, alignment films, liquid crystal materials, thin-mode tr...
