Abstract

The invention discloses a driving method of a touch display panel and a readable storage medium. The driving method comprises the following steps: reading image data of a to-be-displayed image; judging whether the read image data meets a set rule for forming a heavy-load picture or not; if yes, polarity adjustment is carried out on the image data, so that the adjusted image data destroys a set rule; and loading the adjusted image data, and displaying the image. The method comprises the following steps: reading image data of a display image before image display; when the image data satisfies aset rule for forming a heavy-load picture, obtaining a heavy-load picture; if yes, polarity adjustment is carried out on image data; according to the touch display panel, the touch electrodes are arranged on the display panel, so that images displayed by the adjusted image data are not changed, potential of the touch electrodes can be prevented from being pulled towards the same direction to deviate from reference potential of the touch electrodes, set rules can be destroyed, cross grains generated by displaying the images can be avoided when the adjusted image data are loaded, and the displayeffect is optimized.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a driving method and a readable storage medium of a touch display panel. Background technique

[0002] Touch and Display Driver Integration (TDDI for short) technology integrates a touch chip and a display chip into a single chip, thereby enabling a display to have a thinner appearance and lower cost.

[0003] At present, TDDI displays usually have multiple touch electrodes, and the touch electrodes and data lines are generally arranged on different layers. TDDI displays can be driven by column inversion. On the contrary, it drives the liquid crystal to turn over to realize image display. However, when the heavy-duty screen is displayed, the gray scale span of the adjacent color blocks above the heavy-duty screen is relatively large, which will cause the touch electrodes to be coupled differently by the data lines at different positions, and some positions can be restored quick...
