Abstract

The invention discloses a touch control display panel, a driving method thereof and a touch control display device. The touch control display panel comprises multiple touch control electrodes and a touch control drive circuit. The touch control drive circuit comprises a plurality of touch control drive units, the output end of each touch control drive unit is electrically connected with at least one touch control electrode, and the input ends of the touch control drive units are correspondingly and electrically connected with shift signal lines on to one; each touch control drive unit comprises a gating control unit, a public voltage signal output unit and a touch control scanning signal output unit, wherein the input end of the gating control unit is electrically connected with the corresponding shift signal line and used for gating the public voltage signal output unit or the touch control scanning signal output unit on the basis of signals input by the shift signal lines. According to the scheme, alternative output of touch control scanning signals and public voltage signals is achieved by means of few electric components, the layout area occupied by the touch control drive units on the touch control display panel is reduced, and narrow bezel realization of the touch control display panel is benefited.

Description

technical field [0001] The present disclosure generally relates to the field of display technology, and in particular, to a touch display panel, a driving method thereof, and a touch display device. Background technique [0002] The touch display device can detect the coordinate position of the finger in the display screen plane of the touch display device through the touch electrodes, and perform corresponding display according to the coordinate position. [0003] In the current touch display device, the touch function is usually realized by two touch electrode layers, wherein each touch electrode layer has a plurality of touch electrodes arranged in parallel to each other (respectively touch driving electrodes and touch sensing electrodes). ), the extending directions of the touch electrodes in the two touch electrode layers intersect. Apply a touch scanning signal to each touch electrode (touch drive electrode) on one of the touch electrode layers. When a person's finger...
