Problems solved by technology

[0009] However, the layout of the plurality of gate lines / data lines 165 and the plurality of wires 167 on the thin film transistor substrate is relatively crowded, and there is basically no space to add more on the thin film transistor substrate. In order to make the light sensor and brightness Some new lines that are electrically connected to the control circuit, and even if new lines can be added, the wiring is too dense, which is prone to electromagnetic interference (Electro Magnetic Interference, EMI) between lines

Abstract

A liquid crystal display, which includes: a liquid crystal display panel, a light guide plate provided with wires, a drive chip and an optical sensor arranged on the light guide plate, the liquid crystal display panel is provided with a connecting portion, the light guide plate and the liquid crystal display The panels are stacked, and the light guide plate is provided with a connecting part opposite to the connecting part of the liquid crystal display panel. The driving chip is connected to the connecting part by the wire, and is connected to the liquid crystal display panel Electrically connected, the light sensor is electrically connected with the drive chip, the light sensor can sense external light, convert the light signal into an electrical signal and send it to the drive chip. The liquid crystal display can automatically adjust the brightness of the backlight according to the change of the brightness of the outside light, and can alleviate the wiring density and prevent electromagnetic interference between the lines.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display capable of automatically adjusting brightness. Background technique [0002] At present, liquid crystal displays have gradually replaced traditional cathode ray tube (Cathode Ray Tube, CRT) displays used in calculators, and because liquid crystal displays are light, thin, and small, they are very suitable for use in desktop computers, Laptop computers, personal digital assistants (Personal Digital Assistant, PDA), portable phones, televisions and a variety of office automation and audio-visual equipment. [0003] The operating environment of LCD monitors will change with certain conditions, such as different locations, the intensity of ambient light, and light switches. Make corresponding adjustments to the display brightness to obtain the most comfortable visual experience. [0004] A prior art liquid crystal display such as figure 1 As shown, the liquid cr...
