Problems solved by technology

[0006] The liquid crystal display panel using the column inversion method, when driving, in a frame of picture, the turn-on sequence of the scan lines is from top to bottom. When the scan line is at a high potential, the thin film transistor connected to the scan line is turned on, and the other scan lines The thin film transistor connected to the line is at a low potential, and the thin film transistor is in the off state, because the off state current I of the thin film transistor off It is impossible to achieve 0. There may be leakage of thin film transistors to the relative positive electrode potential, resulting in excessive brightness in the high-potential display area and too small brightness in the low-potential display area. Crosstalk, which will have a serious impact on the picture taste of the LCD panel

Abstract

The invention provides an array substrate. The array substrate includes at least pixel units of which each is enclosed by two data lines and two scan lines being vertically interleaved and pixel electrodes which are disposed in the pixel units; wherein the center lines of the pixel units are parallel to the data lines, and the pixel electrodes are arranged asymmetrically relative to the center lines. The array substrate has the advantage that a liquid crystal display panel provided by the invention uses the coupling effect of the data lines to affect the voltage values of the pixel electrodes,and the parasitic capacitance values formed between adjacent two data lines and the pixel electrodes do not cancel each other, thus the potential of the pixel electrodes is pulled, the voltage valuesof the pixel electrodes in different areas are kept close to a preset value, vertical crosstalk is reduced, and uniform screen brightness of the liquid crystal display panel is achieved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an array substrate and a liquid crystal display panel. Background technique [0002] In today's information society, thin-film transistor LCD displays have been widely used in all aspects of our lives, from small-sized mobile phones, video cameras, digital cameras, medium-sized notebook computers, desktop computers, large-sized home TVs to large-scale projection equipment, etc., thin film On the basis of advantages of lightness and thinness, transistor LCD, coupled with perfect picture and fast response characteristics, ensures that it is the leader in the display market. [0003] In an active-matrix LCD, each pixel has at least one thin-film transistor (TFT), whose gate is connected to the horizontal scan line, the source is connected to the vertical data line, and the drain is connected to the pixel electrode . [0004] On the same scanning line in the horizont...
