Abstract

The touch display panel provided by the invention comprises a touch electrode wiring layer, the touch electrode wiring layer comprises a plurality of touch electrodes, and the plurality of touch electrodes are arranged in an array; the signal transmission wiring layer is arranged on one side of the touch electrode wiring layer, the signal transmission wiring layer comprises a plurality of signal transmission line groups, and the signal transmission line groups are electrically connected with the touch electrodes in a one-to-one correspondence mode; wherein the signal transmission line group comprises at least two signal transmission lines, the at least two signal transmission lines are arranged at intervals, and the at least two signal transmission lines are electrically connected with the corresponding touch electrodes. According to the touch display panel and the touch display device provided by the invention, one touch electrode is electrically connected with at least two signal transmission lines, and the at least two signal transmission lines are arranged in parallel, so that the total resistance of the at least two signal transmission lines electrically connected with the touch electrode is reduced; therefore, the resistive and capacitive load on the signal transmission line can be reduced, and the touch precision of the touch display panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel. Background technique [0002] Touch technology has developed rapidly in recent years, and various touch display panels have been put into mass production. A design structure of an existing touch display panel is to provide a touch electrode wiring layer and a signal transmission wiring layer. Wherein, the touch electrode wiring layer includes a plurality of touch electrodes; the signal transmission wiring layer includes at least two signal transmission lines. The plurality of touch electrodes are electrically connected to at least two signal transmission lines in one-to-one correspondence. Existing touch display panels use signal transmission wiring layers to transmit touch signals. [0003] However, as the size of the touch display panel becomes larger, the length of the signal transmission line will become longer, so that the resistive capac...
