Problems solved by technology

[0003] The principle of "whitening on both sides" is: figure 1 As shown, the driving voltage of the scanning Gate line 11 is input by the scanning driving electrodes (Gate COF) 12 located on the left and right sides of the liquid crystal display panel 10, because the resistance R and the capacitance C of the scanning line 11 will generate a delay RC Delay, so that The normal input voltage on both sides is distorted when it is transmitted to the middle area A, that is, the Gate waveform is distorted. The distorted voltage will reduce the charging rate of the middle area A, thereby reducing the display brightness of the middle area A. At this time, the areas B1 and B2 on both sides The display brightness of A is higher than that of the middle area A, that is, the phenomenon of "whitening on both sides" occurs

Abstract

The invention provides a liquid crystal display panel and an array substrate thereof. The liquid crystal display panel is provided with a first substrate and a second substrate, wherein the first substrate and the second substrate are oppositely arranged at intervals; the first substrate comprises a plurality of scanning lines, a plurality of data lines and a plurality of pixel units; the pixel units are defined by the scanning lines and the data lines; and the lengths of pixel electrodes of the pixel units are sequentially reduced towards regions on two sides of the liquid crystal display panel along a middle area of the liquid crystal display panel. By the mode, the display brightness of the liquid crystal display panel is uniform, and a phenomenon of white marks on two sides is relieved or eliminated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and an array substrate thereof. Background technique [0002] When the TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film field effect liquid crystal display) panel is displayed in low grayscale, it is very easy to have a bad display phenomenon that the brightness of the two side areas is high and the brightness of the middle area is low. whitening" phenomenon. [0003] The principle of "whitening on both sides" is: figure 1 As shown, the driving voltage of the scanning Gate line 11 is input by the scanning driving electrodes (Gate COF) 12 located on the left and right sides of the liquid crystal display panel 10, because the resistance R and the capacitance C of the scanning line 11 will generate a delay RC Delay, so that The normal input voltage on both sides is distorted when it is transmitted to the middle area A, t...
