Embodiment Construction
[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] In the related art, in order to avoid vertical lines, the polarities of the data signals obtained by the same column of sub-pixels are arranged alternately, such as figure 2 shown. by figure 2 In the nth row (n is a positive integer) and the n+1th row as an example, after the data line provides a high-level data signal to both the subpixel 1 and the subpixel 2 in the first row, it sends a high-level data signal to the subpixel 3 in the second...

The present invention provides a pixel driving method, a pixel driving circuit, and a display device, in which the polarity of a data signal provided to sub-pixels in odd-numbered rows by a data linein the same column of sub-pixels is different from the polarity of a data signal provided to sub-pixels in even-numbered rows by the data line. The pixel driving method comprises the steps that a dataline is controlled to sequentially charge all sub-pixels connected with the data line according to a preset sequence, the duration difference between the charging duration of a first sub-pixel and the charging duration of a second sub-pixel is smaller than a preset duration, and the first sub-pixel and the second sub-pixel are any two sub-pixels connected with the same data line respectively. According to the pixel driving method, the pixel driving circuit and the display device, the display effect of the display device can be improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving method and device thereof, and a display device. Background technique [0002] With the continuous development of electronic information technology, in order to narrow the frame of the display device and increase the screen ratio, a dual gate structure (Dual Gate) is used to drive the sub-pixels to emit light, that is, one data line drives the sub-pixels of two adjacent columns. way to drive sub-pixels, such as figure 1 As shown, in this way, the effect of reducing the border can be achieved by reducing the number of data lines. [0003] However, in the Dual Gate, the polarities of the data signals obtained by the two columns of sub-pixels connected to the same data line are the same, and the polarities of the data signals obtained by the sub-pixels connected by adjacent data lines are different, and there are bright and dark differences in the positive ...
