Abstract

The invention discloses a driving method of a display panel and the display panel. In the driving method of the display panel, the scanning period of each frame of picture comprises a touch scanning stage and a pixel scanning stage, the scanning time of each frame of picture is equal, and in the pixel scanning stage, pixel scanning pulse signals are input into each row of scanning lines in sequence; in the touch control scanning stage, touch control scanning pulse signals are sequentially input into all columns of touch control lines; wherein the touch scanning frequencies of the touch scanning stages of the at least two frames of pictures are different. According to the invention, the problem that the wave crest appears at a fixed frequency point and has a large radiation value to interfere with the work of surrounding electronic equipment can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a driving method of a display panel and the display panel. Background technique [0002] Display panel manufacturers continue to invest in new production lines or expand production, driving the increase in global display panel production capacity. However, the growth of several major consumer application markets such as smartphones, smart TVs, laptops, and tablets has slowed down, and the market size of some applications has begun to decline. Display panel manufacturers are looking for the next fast-growing application, and automotive display applications have become the focus of attention. But in-vehicle display panels suffer from electromagnetic interference (EMI) with everything else in the surrounding environment. Contents of the invention [0003] In view of this, the present invention provides a display panel driving method and the display panel, which...
