LCD panel of thin-film transistor

Abstract

The invention relates to a thin film transistor liquid crystal display panel. The thin film transistor liquid crystal display panel comprises a data line drive circuit, and an array basal plate forming a panel display area. A display brightness control device capable of changing the liquid crystal display brightness according to the brightness of the environment is connected in series between a data line output end of the data line drive circuit and a data line input end of the array basal plate. The display brightness control device comprises two thin film transistors which are sedimentated outside the display area of the array basal plate of the liquid crystal display, and two diodes which are integrated in the data line drive circuit. The liquid crystal display panel can control the liquid crystal display brightness according to the brightness of the environment, thereby allowing the liquid crystal display brightness to change with the brightness of the environment.

Description

technical field [0001] The invention relates to a liquid crystal display panel, in particular to a thin film transistor liquid crystal display panel capable of adjusting display brightness according to the brightness of ambient light. Background technique [0002] The liquid crystal in the thin film transistor (Thin Film Transistor, referred to as TFT) liquid crystal display (LiquidCrystal Display, referred to as LCD) is clamped by the array substrate and the color filter substrate, the color filter substrate has a color resin and common electrodes, and the array substrate has TFT and pixels When a voltage is applied between the common electrode and the pixel electrode, the liquid crystal emits light. For a twisted nematic (TN) mode normally white LCD, the smaller the voltage difference between the two sides of the liquid crystal, the greater the brightness of the liquid crystal.

Problems solved by technology

[0003] In an environment that is highly dependent on ambient brightness, the display brightness of the TFT LCD needs to be able to make corresponding changes, that is, when the ambient light is relatively strong, the brightness of the liquid crystal display is strong, and when the ambient light is relatively weak, the brightness of the liquid crystal display is weak. However, in the prior art, the display brightness of TFT LCD cannot be adjusted according to the change of ambient light.
