Method and device for driving touch display panel

A device for driving a touch display panel, comprising:

• an acquisition circuit, configured to acquire image data of an image to be displayed;
• a judgment circuit, configured to judge whether the acquired image data is a reloaded picture with a default polarity mode, wherein the default polarity mode comprises:
• polarities of the image data corresponding to each two adjacent data lines are opposite, and polarities of the image data corresponding to a same data line are the same;
• an adjustment circuit, configured to perform polarity adjustment on the image data when the image data is judged to be the reloaded picture with the default polarity mode;
• and
• a display driving circuit, configured to drive the touch display panel to display image according to the image data after polarity adjustment.

A computer device, comprising a memory, a processor, and computer programs stored on the memory and capable of running on the processor, wherein the processor is configured to read and execute the computer programs to perform following operations:

• acquiring image data of an image to be displayed;
• judging whether the acquired image data is a reloaded picture with a default polarity mode, wherein the default polarity mode comprises:
• polarities of the image data corresponding to each two adjacent data lines are opposite, and polarities of the image data corresponding to a same data line are the same;
• performing polarity adjustment on the image data when judging that the image data is the reloaded picture with the default polarity mode;
• and
• driving a touch display panel to display image according to the image data after polarity adjustment.
