Problems solved by technology

In order to reduce the cost, the dual gate (Dualgate) pixel structure is more and more widely used in LCD, but the dual gate pixel still needs half of the driver IC (integrated circuit) data line, and the degree of cost reduction is limited

Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0024] figure 2 It is a schematic diagram of the pixel repeating unit structure with quadruple gate wiring in the present invention. Such as figure 2 As shown, each pixel repeating unit has a pixel unit, four gate lines, a data line, and a COM line. The pixel unit is composed of four sub-pixels of R, G, B and W, which is a 2*2 matrix The arrangement is in the shape of "Tian", a thin film transistor (TFT) and a pixel electrode are arranged in each sub-pixel area, and four gate (Gate) traces G n , G n+1 , G n+2 and G n+3 Composed of Zig zag routing and straight routing, it is arranged between the first row of sub-pixels and the second row of sub-pixels, the data (Dn) routing connects 4 TFTs in a pixel repeating unit, and provides R...

Abstract

The invention provides a multi-grid pixel structure and a driving method thereof, and belongs to the technical field of display. The pixel structure with four times of grid wires is innovatively adopted for the pixel layout mode shaped like a Chinese character 'tian', the driving mode of grid driving signals is adjusted, the liquid crystal display driving of the multi-grid pixel structure is realized, the data signal writing-in requirement of each pixel is met, a data wire is shared by four pixels, the opening rate of the pixels is increased due to the sharing of the wires, the number of Source IC is one quarter that of a frequently-used single-grid wire pixel structure, IC driving data signals are further saved, and process cost is reduced. By means of the technical scheme, W / Y pixels andR / G / B pixels are controlled by different grid wires, the control over the displaying of the W / Y pixels is easy, and an IC algorithm is simplified.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a multi-gate (multi Gate) pixel structure and a driving method thereof. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) includes a gate driving circuit, a data driving circuit and a pixel area. Wherein, the gate drive circuit includes a plurality of gate lines, which sequentially generate gate drive signals, and the data drive circuit includes a plurality of data lines, which are used to generate data drive signals, each gate line is a straight line parallel to each other, and each data line are straight lines parallel to each other; the pixels in the pixel area are formed by interlacing gate lines and data lines, and are driven by gate drive signals generated by corresponding gate lines to receive data drive signals generated by corresponding data lines. In order to reduce the cost, the dual-gate (Dualgate) pixel structure is mo...
