Abstract

The invention relates to an array basal plate and an arrangement basal plate of a liquid crystal display device, wherein the array basal plate comprises a plurality of pixels, each pixel comprises a first thin film transistor connected with a corresponding grid line and a corresponding data wire and a pixel electrode connected with the first thin film transistor, and each pixel also comprises a second thin film transistor; and the second thin film transistor is connected with a grid line in front of the grid line connected with the first thin film transistor, and the second thin film transistor is also connected with the data wire and the pixel electrode connected with the first thin film transistor. In the invention, signals remained in a pixel unit are simultaneously released through the first thin film transistor and the second thin film transistor in the pixel unit while powering off, thus, the efficiency of releasing residual signals is effectively improved by a structure that the residual signals are released through one thin film transistor compared with the prior art, thereby effectively the performance of resisting photogene of the liquid crystal display device while powering off and the quality of the liquid crystal display device are improved.

Description

technical field [0001] The invention relates to an array substrate and an arrangement substrate of a liquid crystal display device, in particular to an array substrate and an arrangement substrate of a liquid crystal display device with high anti-residual image during abnormal shutdown. Background technique [0002] The liquid crystal display device is a main flat display device, which is mainly composed of an array substrate, a color filter substrate and a timing controller that provides signals to the array substrate. , the screen is displayed. [0003] In the prior art, a pixel of a liquid crystal display device is usually equipped with a thin film transistor, and when an abnormal shutdown occurs, an afterimage remains on the screen because the voltage cannot be released in time. Or there is a defect in the screen before the screen is displayed when the machine is turned on immediately after an abnormal shutdown. Specifically: when the power of the liquid crystal displa...
