Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a display panel and a driving method thereof. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current display field. [0003] The main structure of the liquid crystal display is the display panel, such as figure 1 As shown, the display panel includes an array substrate 10 and a cell-aligning substrate 20 arranged for cell alignment, a liquid crystal layer 30 located between the array substrate 10 and the cell-aligning substrate 20, and a lower polarizer 40 located on the side of the array substrate 10 and a cell-aligning substrate 40. The upper polarizer 50 on the side of the substrate 20 , the array substrate 10 and the cell assembling substrate 20 ar...

Problems solved by technology

[0004] When the display panel with the above structure is in the display state of L0 (gray scale is 0), as figure 2 As shown, the first alignment film 13, the second alignment film 22 ( figure 2 not shown in ), the orientation direction of the lower polarizer 40 (the line with the arrow in the figure) is consistent with the long axis direction of the liquid crystal molecules in the liquid crystal layer 30, when the incident light passes through the lower polarizer 40 to obtain linearly polarized light , when the linearly polarized light enters the liquid crystal layer 30, its polarization direction will not change, and since the polarizing axis direction of the upper polarizer 50 and the lower polarizer 40 is perpendicular, the linearly polarized light cannot pass through the upper polarizer 50, presenting dark state display

[0005] During transportation, testing, and use, the display panel is often subjected to oblique external forces, causing the spacer 21 to move. 13 is damaged, resulting in poor alignment (that is, when the first alignment film 13 is prepared, its alignment is consistent (such as Figure 3a shown), the deflection angle is 0, when the first alignment film 13 is scratched, the alignment disorder in the scratched area (such as Figure 3b As shown), the deflection angle changes), resulting in disordered arrangement of liquid crystal molecules, resulting in light leakage

[0006] Most of the existing solutions are to increase the structural strength of the module and improve the handling process of the production line, but the strength of the module is greatly affected by the material and process and will increase the product cost, while improving the handling process will increase the difficulty of the operation and the effect is unstable. , none of the existing methods can fundamentally solve the problem of light leakage
