Problems solved by technology

[0003] In a display device, every certain number of scanning lines, the data signal will be inverted, because at least in the process of turning on part of the scanning lines, the polarity of the data signal is converted from negative to positive, or from positive to negative , causing the pixels in these scanning lines to have a long conversion delay when being charged, and the actual charging time of pixels in different scanning lines is different, making the charging effect in the entire display panel uneven. Correspondingly, when the display screen is When the brightness of the gray scale is uniform, the actual display effect is also uneven, which usually appears as faint bright and dark lines on the display screen that are consistent with the extension direction of the scanning line

Abstract

The present application discloses a display driving method and a display device, wherein the display driving method includes the following steps: when the scanning signal connected to the scanning line of the pixel is switched from the off level to the first on level, if the scanning signal connected to the pixel The data signal on the data line is converted from the first polarity to the second polarity, then before the data signal is converted from the first polarity to the second polarity, when the data signal is in the second polarity, the control scan signal is in The second conduction level is used to precharge the pixels with the data signal. The technical solution of the present application can improve the display uniformity and improve the display effect.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display driving method and a display device. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. The display panel is an important part of the display device, which includes a plurality of pixels, and each pixel displays a certain grayscale brightness under the driving action of a switching device to form a display image. Usually, the display is driven in a progressive scanning manner. Under the control of the scanning signal on the scanning line, the pixels in the corresponding scanning line are charged by the data signal on the data line to display a certain grayscale brightness. In order to improve the display effect of the display device, in the process of driving the display, the polarity of the data signal is usually reversed in a certain way. ...
