Abstract

The invention discloses a display panel having a touch control function and a touch control detection method of the display panel. A gate driver of the display panel executes gate driving actions on gate lines, first time slots are set between the adjacent gate driving actions of the same display frame, second time slots are set between the adjacent gate driving actions of every two adjacent display frames, and a touch control driver executes touch control driving actions on touch control electrodes within the first time slots and the second time slots in sequence. By means of the mode, the display panel having the touch control function and the touch control detection method of the display panel can avoid the mutual interference of display signals and touch control signals, and the display quality and the touch control effect of the display panel can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel with a touch function and a touch detection method thereof. Background technique [0002] Currently, display panels with integrated touch and display functions are becoming more and more popular. Among them, the In-cell technology, which embeds capacitive touch functions into pixels, is becoming more and more popular because of its advantages in realizing thinner and lighter display panels. Trends in this field. In a display panel using in-cell technology, the driving frequency of the touch electrode is usually higher than the scanning driving frequency of the gate line, so that there is overlap between the display signal and the touch signal during the scanning process of the same display frame, thereby interfering with each other , affecting the touch effect and display quality of the display panel. Contents of the invention [0003] The inven...
