Abstract

The present invention discloses a touch display panel and a touch display apparatus comprising the touch display panel. The touch display panel comprises a first touch electrode array and multiple first touch signal lines. The first touch electrode array comprises M*N first touch electrodes. Each first touch electrode column in the first touch electrode array is divided into at least two touch electrode groups. Each first touch electrode in the same touch electrode group is electrically connected by using at least one first touch signal line, and first touch electrodes of different touch electrode groups are insulated. One frame period comprises K touch detection periods. In each touch detection period, at least two first touch electrode columns receive a touch drive signal. First touch electrodes in each first touch electrode column are grouped and connected, so that a drive load driving multiple first touch electrode columns simultaneously is lowered.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel and a display device. Background technique [0002] In a mutual capacitive touch display screen, the touch transmitting electrodes and the touch receiving electrodes on the touch display panel are generally disposed across the display area, and a mutual capacitance is formed at the intersections. Upon touch, the amount of charge stored by the mutual capacitance at the touch location changes. Therefore, the touch position can be determined according to the intersection point where the signal intensity sensed by the mutual capacitance changes, thereby realizing the touch function. [0003] The touch emitter electrodes on the touch display panel are usually strip electrodes, that is, extending along one direction and arranged along a direction perpendicular to the direction. The driving unit generally sends a touch driving signal from one end of th...
