Problems solved by technology

[0003] In the existing large-size liquid crystal display panel, it is generally driven by a double-sided scanning driving method. Due to the influence of the delay circuit, the charging rate of the left and right sides of the liquid crystal display panel near the driver chip will be higher than that of the middle area of ​​the panel. The charging rate makes the left and right sides of the LCD panel brighter and the middle darker, that is, the phenomenon of whitening on the left and right sides of the LCD panel appears, which has an adverse effect on the display quality of the LCD panel.

Embodiment Construction

[0062] see figure 1 , is a schematic structural diagram of the array substrate 1 of the present invention. Such as figure 1 As shown, the array substrate 1 is provided with a plurality of scanning lines and a plurality of data lines, and the scanning lines and data lines are arranged on the side of the array substrate 1 close to the liquid crystal layer, and the plurality of data lines and the plurality of scanning lines cross each other to divide the array substrate 1 into a plurality of pixel regions 2 . Generally, the multiple data lines are arranged parallel to each other, the multiple scan lines are arranged parallel to each other, and the data lines and the scan lines intersect perpendicularly with each other. In other implementation manners, the multiple data lines and the multiple scan lines are also Other arrangements may be used.

[0063] Please refer to figure 2, is an equivalent circuit diagram of the array substrate 1 of the present invention. Each pixel are...

Abstract

The invention discloses an array substrate and a liquid crystal display panel. The array substrate comprises a plurality of scanning lines and a plurality of data lines. The scanning lines and the data lines are crossed to divide the array substrate into a plurality of pixel areas. Each pixel area comprises a main pixel area body and an auxiliary pixel area body. Each auxiliary pixel area body comprises a sharing capacitor, and the capacitance value of the sharing capacitor is sequentially decreased from the edge of the array substrate to the center of the array substrate. During display, the electric potential on each auxiliary pixel area body on the edge of the array substrate is smaller than the electric potential on each auxiliary pixel area body at the center, and therefore the luminance of each auxiliary pixel area body at the center of the array substrate is larger than the luminance of each auxiliary pixel area body on the edge, the aim of eliminating whitening on the two sides is achieved, and display quality is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] Liquid crystal displays have many advantages such as thin bodies, power saving, and no radiation, and are widely used. Most of the liquid crystal displays on the existing market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module; the working principle of a liquid crystal display panel is to place liquid crystal molecules in two parallel glass substrates, Apply a driving voltage to control the rotation direction of the liquid crystal molecules to refract the light from the backlight module to produce a picture. [0003] In the existing large-size liquid crystal display panel, it is generally driven by double-sided scanning driving. Due to the influence of the delay circuit, the charging rate of the left and right sides of the...
