Dehumidifying TFT-LCD (Thin Film Transistor-Liquid Crystal Display) display screen capable of preventing influence of ambient lighting

Abstract

The invention discloses a dehumidifying TFT-LCD (Thin Film Transistor-Liquid Crystal Display) display screen capable of preventing the influence of ambient lighting, which comprises a thin film transistor substrate layer arranged at a middle position, the thin film transistor substrate layer comprises a bottom transparent substrate layer, an amorphous silicon plate layer is formed upon a protective plate layer, dehumidifying cartridges are fixedly arranged at the positions of both screen ends of the TFT-LCD display screen, the cavity of each dehumidifying cartridge is arranged as a hollow structure and a moisture-absorbing sponge block is arranged in the cavity, and shock-absorbing springs are arranged on the bottom sections of the bodies of the dehumidifying cartridges. The invention can effectively prevent the problem that light fluid can be generated by a thin film transistor substrate layer when a liquid crystal display screen is under the lighting effect of strong light, so that a series of problems, such as the influence of irradiation of outside light on the current and voltage of the whole display screen in use, are prevented. During use, the invention effectively ensures that the interior of the TFT-LCD display screen is always in a dry state and cannot be affected by a humid environment.

Description

Problems solved by technology

As one of the important core basic components of the electronic information industry and the replacement of traditional picture tube display technology in the future, liquid crystal display technology plays an important role in promoting the transformation of economic development mode, promoting the optimization and upgrading of industrial structure, and driving the development of high-tech; However, once the traditional TFT-LCD display screen is under the action of strong light, the substrate layer of the thin film transistor will produce light fluid problems, which will cause the current and voltage instability of the entire display screen, and the actual use effect of the user will be affected. During use, it is easily affected by the humid environment. Once the moisture vapor in the external environment enters the inner cavity of the TFT-LCD display, the display will be short-circuited, damaged and cannot be used normally, and needs to be resolved.
