Embodiment 1

[0018] figure 2 For the schematic diagram of the pixel array provided by the embodiment of the present invention, please refer to figure 2 , the detailed structure of the pixel array provided by Embodiment 1 of the present invention is as follows:

[0019] There are multiple pairs of adjacently arranged first scanning lines and second scanning lines, and a row of pixel units is respectively arranged on opposite outer sides of the first scanning lines and the second scanning lines. For example, the first scanning line 11 and the second scanning line 12 are a pair of adjacent scanning lines, and a row of pixel units A1 is arranged on the outside of the first scanning line 11 relative to the second scanning line 12. 12 is provided with a row of pixel units A2 on the outside of the first scanning line 11 . The first scanning line 21 and the second scanning line 22 are a pair of adjacent scanning lines. A row of pixel units A1 is arranged on the outside of the first scanning li...

Embodiment 2

[0037] Please refer to Figure 4 , Figure 4 It is a schematic diagram of the pixel array provided by Embodiment 2 of the present invention. Different from the first embodiment, in the second embodiment, the common electrode lines 101, 102, 103 and 104 are not arranged under the common electrodes but outside the pixel units, specifically, the common electrode lines 101 are arranged on The first pixel unit A1 row is away from the side of the first scan line 11 , and the common electrode line 102 is arranged on the side of the second pixel unit A2 row away from the second scan line 22 . Similarly, the common electrode line 103 is set on the side of the first pixel unit A1 row away from the first scan line 31 , and the common electrode line 104 is set on the side of the second pixel unit A2 row away from the second scan line 42 .

[0038] The two adjacent common electrode lines 102 and 103 plus the width H1 of the gap between them, the two adjacent first scanning lines 11 and t...

Abstract

The invention provides a pixel unit array. A signal of a first common electrode is used for compensating for voltage change of a first pixel electrode, wherein the voltage change of the first pixel electrode is caused by coupling capacitance change resulting from voltage change of a second scanning line; a signal of a second common electrode is used for compensating for voltage change of a second pixel electrode, wherein the voltage change of the second pixel electrode is caused by coupling capacitance change resulting from voltage change of a first scanning line. The pixel unit array solves the problem that the brightness of odd-numbered lines of pixels and the brightness of even-numbered lines of pixels are not uniform in the prior art.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a pixel unit array, a liquid crystal display panel and a method for driving the pixel unit array. Background technique [0002] Liquid Crystal Display (LCD), which is a flat and ultra-thin display device, consists of a certain number of color or black and white pixels, which are placed in front of a light source or a reflective surface to form a display. Due to the advantages of low power consumption, thin body, and low radiation, liquid crystal display devices are favored by the market, and have now become mainstream products in the display field. However, due to product design defects or manufacturing process deviations, abnormal display of the liquid crystal display device, such as uneven brightness and darkness of the display, often occurs. Contents of the invention [0003] Please refer to figure 1 , is a schematic diagram of a liquid crystal display device in the p...
