Problems solved by technology

The control circuit will cause shading and reduce the penetration rate of the sub-pixel, which is not conducive to the specification of the display panel
[0004] In addition, the difference in brightness between the main part and the secondary part will also cause color unevenness such as rhombic patterns and broken colors. Therefore, a solution is really needed in this field to improve the display effect of the display panel.

Embodiment Construction

[0041] figure 1 It is a schematic diagram of pixel arrangement of the display panel 100 according to the embodiment of the present invention. The display panel 100 may include a plurality of pixels, and each pixel may be used to display a color. figure 1 The pixels in are all pixels displaying the same color, and these pixels may include a pixel PH, a pixel PI, and a pixel PL. A plurality of pixels PH may constitute a first group of pixels, a plurality of pixels PI may constitute a second group of pixels, and a plurality of pixels PL may constitute a third group of pixels. The arrangement of the pixel PH, the pixel PI, and the pixel PL can be as follows figure 1 shown. according to figure 1 In this embodiment, in the nth row of the display panel 100, the plurality of pixels PH of the first group of pixels and the plurality of pixels PL of the third group of pixels may be alternately arranged, and in the (n+1)th row, the plurality of pixels of the second group of pixels Th...

Abstract

The present invention provides a method for driving a display panel and a display panel. The display panel comprises a plurality of pixels configured to display one color, and the pixels include a first group of pixels, a second group of pixels and a third group of pixels. The method comprises: when the pixels are controlled to display first data, the first group of pixels provide first voltage, the second group of pixels provide second voltage, and the third group provides third voltage; and when the pixels are controlled to display the second data, the first group of the pixels and the second group of the pixels provide fourth voltage, and the third group of the pixels provide fifth voltge. The first data is smaller than a first threshold value, and the second data is larger than the first threshold value. The first voltage is higher than the second voltage and the third voltage, and the fourth voltage is higher than the fifth voltage.

Description

technical field [0001] The present invention relates to a method for driving a display panel, a display panel, a method for driving a display panel according to a gamma curve, and a display panel. Background technique [0002] Current display panels, such as liquid crystal panels, often suffer from color washout problems, especially when users view them at large oblique angles such as side viewing angles, the color washout problem is more likely to occur. In the side viewing angle, the gamma curve of the display panel is often different from the gamma curve viewed in the front viewing angle, so that when the gray scale to be displayed is increased, the brightness increase is higher than the front viewing angle, so the whitening problem occurs . [0003] In order to improve the whitening problem, the sub-pixel (sub-pixel) of the display panel can be divided into the main part and the secondary part. By turning on the main part first, the main part can reach the predetermined...
