Embodiment Construction

[0027] In the process of manufacturing the liquid crystal display device, the inventors of the present invention found that due to the influence of the parasitic capacitance, pixel electrodes with gray scale changes exist in the same column, which causes vertical stripes.

[0028] The inventors of the present invention found that through creative work, adjusting the connection mode between the gate of the thin film transistor of each pixel electrode and the scanning line makes the pixel electrodes with gray scale changes distributed in different columns, thereby avoiding gray scale changes The vertical stripe phenomenon caused by the concentration of pixel electrodes in one column, and the aperture ratio is guaranteed without increasing the distance between pixels in two adjacent columns.

[0029] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail...

Abstract

The invention provides a liquid crystal display device. The liquid crystal display device comprises a pixel array consisting of a plurality of sub-pixel arrays arranged in an array way; each sub-pixel array comprises a structure which contains two rows and two columns of pixels and consists of four pixel electrodes, four thin film transistors, a data line and four sequentially arranged scanning lines; the sources of the four thin film transistors share the data line; the drain of each thin film transistor is connected with a pixel electrode; the grids of the two thin film transistors of one column are connected with the two scanning lines in the middle respectively, and the grids of the two thin film transistors of the other column are connected with the other two scanning lines; and whenthe liquid crystal display device is driven, the four scanning lines are used for scanning sequentially. As the pixel electrodes having gray scale variation are arranged on the different columns, a vertical bar phenomenon due to non-uniform periodic gray scales can be avoided; and the aperture opening ratio can be guaranteed.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a pixel array of the liquid crystal display device. Background technique [0002] see Figure 1 to Figure 3 As shown, the prior art provides a pixel array of a liquid crystal display device, the pixel array includes a plurality of sub-pixel arrays 1 arranged in an array, and each sub-pixel array 1 includes four pixel electrodes 11A, 11B, 11C and 11D , four thin film transistors 12A, 12B, 12C and 12D, one data line S11 and four scan lines G11 to G14 arranged in sequence to form a structure of two rows and two columns, in this structure, the drain of each thin film transistor and One pixel electrode is connected, and the pixel electrodes of each row are respectively connected to two scanning lines through the gate of the thin film transistor to form a dual scanning line structure (dual gate). Specifically, the pixel electrodes 11A and 11B are respectively connected to the Scannin...
