Problems solved by technology

[0003] However, when the touch phase ends and enters the display phase, the change of the voltage signal on the data line will impact the touch electrode, causing the voltage on the touch electrode to change suddenly. At this time, the corresponding liquid crystal cannot be deflected to the preset position. Angle, resulting in abnormal display on the display screen, such as abnormal horizontal lines

Abstract

The embodiment of the invention provides a driving method of a display panel, the display panel and a display device, and relates to the technical field of liquid crystal display. After the touch control stage is over and the display stage starts, the probability of occurrence of abnormal display caused by voltage jump of a touch control electrode can be reduced. The driving method of the display panel includes that after the touch control stage is over and the display stage starts, charging voltage corresponding to the front N rows of to-be-charged pixel electrodes in the display stage is compensated, and according to the compensated charging voltage, the front N rows of to-be-charged pixel electrodes are charged, wherein N is an integer larger than or equal to 1. The driving method of the display panel, the display panel and the display device are mainly used in the charging process of the pixel electrodes.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a driving method of a display panel, a display panel and a display device. Background technique [0002] The current touch display device includes touch electrodes distributed in a matrix. The display device works in the touch stage and the display stage. The touch stage and the display stage are alternately performed. For example, in the display stage, the first to nth rows are scanned first. , during the scanning process, the pixel electrodes in the first to nth rows are charged sequentially, and at the same time, in the display phase, the common electrode voltage signal is provided to the touch electrodes; Provide touch signals; after the previous touch stage ends, enter the next display stage, continue to scan the n+1th to mth rows, and charge the n+1th to mth rows of pixel electrodes in turn during the scanning process , at the same time, in the displ...
