Problems solved by technology

[0004] Choosing a 2Line inversion structure or a 1+2Line inversion driving circuit structure with interleaved polarity can improve the shaking head problem, but as the size of the panel increases, the resolution requirements are higher. Under high demand, the output polarity switching frequency of the drive circuit must also be increased accordingly, which will cause the temperature of the drive circuit to rise, and it is easy to have problems such as abnormal operation of the drive circuit or even stop operation due to overheating.

Abstract

The invention provides a pixel driving circuit structure of a liquid crystal display panel. The pixel driving circuit is of a two-point inversion (2 dot flip) voltage polarity staggered driving circuit structure. The voltage polarity arrangement mode of the vertically adjacent pixel units in the same row is positive and negative sequence switching arrangement; the situation that the polarities ofthe sub-pixels are the same in the whole row is avoided in space, and even if the positive and negative polarity pressure difference of the display panel is actually asymmetric, the phenomenon of Vertical line can be avoided when the liquid crystal display panel displays a pure-color picture.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel display, in particular to a pixel driving circuit structure of a liquid crystal display panel which can improve the phenomenon of shaking head lines. Background technique [0002] Liquid Crystal Display panel (LCD panel) has become a fairly common product. The LCD panel includes a plurality of pixel units (pixels) arranged in a matrix, and each pixel unit includes red (Red, R), green (Green, G), blue (Blue, B) three sub-pixels (subpixel), through the matrix control circuit to apply voltage to the corresponding sub-pixel, so that the corresponding sub-pixel presents the required color, to Display the desired screen on the LCD panel. [0003] In the pixel driving circuit of the liquid crystal display panel, the driving circuit of the column inversion structure is often used to reduce the power consumption of the driving circuit, but the dual gate (Dual gate) driving circuit structure o...
