Abstract

The invention discloses a touch control display panel and a touch control display device. The touch control display panel comprises a plurality of touch control areas which are sequentially arranged in the first direction or the second direction, and each touch control area comprises a plurality of touch control electrodes; the touch display panel further comprises a substrate, the first direction and the second direction are both parallel to the plane where the substrate is located, and the first direction intersects with the second direction. The working stage of the touch display panel comprises a touch detection stage, and in the touch detection stage, the sequence of touch signals received by the touch electrodes in the touch areas is not completely the same as the arrangement sequence of the touch areas. According to the technical scheme provided by the embodiment of the invention, the touch signal receiving sequence of the touch electrodes in the touch area is not completely the same as the arrangement sequence of the touch area, that is, the touch detection rate is improved by adjusting the touch signal receiving sequence of the touch electrodes in the touch area, and the touch sensitivity is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] Touch operation is a simple and convenient way of human-computer interaction, and more and more products integrate touch functions into display devices. The existing touch display device includes a plurality of touch electrodes, touch wires electrically connected to each touch electrode one by one, and a touch chip electrically connected to the touch wires, wherein the touch wires are used for The touch scanning signal of the touch chip is transmitted to the touch electrode. With the continuous increase of the size of the touch display device or the continuous improvement of the touch precision, the touch electrodes and the touch traces gradually increase, and the signal pins of the touch chip increase accordingly. [0003] In order to simplify the touch control method, the touch scanning s...
