Embodiment 1

[0046] Such as Figure 5 As shown, it is a flowchart of a dual gate horizontal pixel inversion driving method disclosed in Embodiment 1 of the present invention, which mainly includes the following steps:

[0047] In step S101 , only one gate line is turned on in each preset time period, and a gate signal is sent to the gate of the thin film transistor of the sub-pixel connected to the gate line.

[0048] During the execution of step S101, only one gate line can be turned on within a preset period of time, such as Image 6 As shown, G1 is turned on in the first time period t1; G1 is turned off and G2 is turned on in the second time period t2; G2 is turned off and G3 is turned on in the third time period t3; For a liquid crystal display with column data lines, Gm-1 is turned off and Gm is turned on within the mth time period tn. And sequentially within a corresponding time period, a gate signal is sent to the gate of the TFT of the sub-pixel electrically connected to the gate...

example 1

[0056] In the horizontal direction, starting from the first sub-pixel in the first row, the data line electrically connected to the first sub-pixel inputs a positive polarity signal, and the data line electrically connected to the second sub-pixel in the first row inputs a negative electrode polarity signal, the data lines electrically connected to the first row input the polarity-inverted polarity signal sequentially until the last sub-pixel.

[0057] In the vertical direction, the data lines electrically connected to the sub-pixels in the second row adjacent to the first row are sequentially input with the same polarity signal as that of the sub-pixels in the first row; The data lines electrically connected to the sub-pixels in the third row that are separated from each other by one row are sequentially input with a signal of a polarity opposite to that of the sub-pixels in the first row.

example 2

[0059] In the horizontal direction, starting from the first sub-pixel in the first row, the data line electrically connected to the first sub-pixel inputs a negative polarity signal, and the data line electrically connected to the second sub-pixel in the first row inputs Positive polarity signals, the data lines electrically connected to the first row input the polarity-inverted polarity signals sequentially until the last sub-pixel;

[0060] In the vertical direction, the data lines electrically connected to the sub-pixels in the second row adjacent to the first row are sequentially input with the same polarity signal as that of the sub-pixels in the first row; The data lines electrically connected to the sub-pixels in the third row that are separated from each other by one row are sequentially input with a signal of a polarity opposite to that of the sub-pixels in the first row.

[0061] Through the above-mentioned starting from the data lines with different polarity signals...

Abstract

The invention discloses a bigrid horizontal pixel reversal driving method which mainly comprises the steps of only opening one gate line in each preset time period, and sending grid signals to a thin film transistor grid of a sub-pixel, connected with the gate line; opening a data line in each preset time period, and in transverse, inputting polar signals with opposite polarities to the data line which is electrically connected with two adjacent sub-pixels; and in longitudinal, from a first line sub-pixel, inputting polar signals with the same polarities to the data line which is electrically connected with an adjacent line of sub-pixels, and inputting polar signals with opposite polarities to the data line which is electrically connected to every two alternate lines of the sub-pixels. According to the bigrid horizontal pixel reversal driving method, the polarity-reversal mode is used for driving, corresponding polarity positive polarity and negative polarity of the transverse sub-pixels are enabled to appear alternately, and two-two corresponding polarity positive polarity and negative polarity of the longitudinal sub-pixels are enabled to appear alternately. Therefore, voltage interference between sub-pixels with close distances is lowered, the condition of color cast is improved, and the visual defect of a liquid crystal display is reduced.
