Abstract

The invention provides a built-in touch control display device and a driving method of the built-in touch control display device. A shielding layer is arranged between a data line and a touch control driving electrode, a touch control driving signal is transmitted to the corresponding touch control driving electrode when a first grid line set corresponding to a common electrode is in an opening state, and the touch control driving signal stops being transmitted to the corresponding touch control driving electrode when a second grid line set corresponding to the touch control driving electrode is in an opening state. Display driving and touch control detection are carried out synchronously, the touch control detection time is prolonged, the transmitting efficiency of a touch control detection signal is reduced, the noise of the touch control display device is further lowered, and the display quality of the touch control display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an in-cell touch display device and a driving method thereof. Background technique [0002] As an input medium, a touch screen provides users with better convenience than a keyboard and a mouse. According to different implementation principles, the touch screen can be divided into resistive, capacitive, surface acoustic wave, infrared and so on. Currently, resistive and capacitive touch screen technologies are widely used. [0003] Capacitive touch screens may specifically include surface capacitive touch screens, projected self-capacitive touch screens, projected mutual capacitive touch screens, and single-layer capacitive touch screens. Among them, the projected mutual capacitance touch screen, with its high sensitivity and the advantages of multi-touch, has been more and more sought after. The basic principle of the projected mutual capacitance touch screen is: appl...
