Problems solved by technology

[0002] The touch display panel includes a self-capacitive touch panel and a mutual-capacitance touch panel. However, the touch performance of the self-capacitive touch panel is not uniform, especially for the touch control of the in-cell touch display panel due to the connection of each touch electrode. The number of lead wires is different, resulting in uneven display colors on the display screen, which affects the display effect
