Problems solved by technology

like figure 1 As shown, the side of the special-shaped touch electrode 5 close to the boundary of the display area 2 is designed as an arc. At this time, the area of ​​the special-shaped touch electrode 5 is smaller than the area of ​​the normal touch electrode 4, resulting in the touch sensitivity of the special-shaped touch electrode 5 and The touch sensitivity of normal touch electrode 4 is inconsistent

Abstract

The present application provides a touch display panel and a touch display device including the touch display panel. The touch display panel is divided into a non-rectangular display area and a non-display area arranged on the periphery of the display area. At the same time, the touch display The panel includes a plurality of first touch electrodes disposed on the display area and a plurality of second touch electrodes disposed on the side of the first touch electrodes close to the non-display area, wherein the second touch electrodes are connected to the first touch electrodes have different shapes, the area of ​​the first touch electrode is S1, the area of ​​the second touch electrode is S2, and 0.85S1≤S2≤1.15S1. The display area of ​​the touch display panel provided by the present invention has a special-shaped design, and the touch uniformity of the touch display panel of the present invention can be effectively improved.

Description

technical field [0001] The present invention relates to the field of touch control, in particular to a touch display panel and a touch display device. Background technique [0002] Usually, the touch electrodes in the touch screen are of rectangular design. Currently, non-rectangular touch screens are more and more widely developed and applied. When the touch electrodes in the non-rectangular touch screen adopt a rectangular design, the touch electrodes may exceed the display area. , affect the display signal transmitted by the signal lines in the peripheral area, etc., so usually the touch electrodes near the edge of the special shape will be specially designed. [0003] like figure 1 shown, figure 1 It is a schematic diagram of a touch display panel in the prior art. The circular touch display screen includes a display area 2 and a non-display area 1 surrounding the display area 2 , wherein the circular dotted frame can be regarded as the boundary of the display area 2 ....
