Abstract

The invention discloses a touch panel, a touch display panel and a touch display device. The touch panel comprises a sensing layer which comprises a first sensing part and a second sensing part, the first sensing part being arranged in a special-shaped area of a substrate, and the second sensing part being arranged in a non-special-shaped area of the substrate; wherein the first sensing part comprises a plurality of first touch electrode blocks distributed in the first direction and arranged in a mutual insulation mode and a plurality of second touch electrode blocks distributed in the seconddirection and arranged in a mutual insulation mode, the first direction and the second direction are mutually crossed, and the second sensing part comprises a first conducting layer and a second conducting layer; and an insulating layer, covering the plurality of first touch control electrode blocks and the plurality of second touch control electrode blocks on the first sensing part, the second sensing part being located between the first conducting layer and the second conducting layer, and the first touch control electrode blocks and the second touch control electrode blocks being located onthe same layer as the first conducting layer. According to the touch panel provided by the embodiment of the invention, the touch accuracy of the touch panel can be improved.

Description

technical field [0001] The invention relates to the field of touch sensing, in particular to a touch panel, a touch display panel and a touch display device. Background technique [0002] With the continuous development of touch screens, touch panels are gradually and widely used in the field of terminal equipment. Touch panels can be classified into resistive, capacitive, optical, acoustic, etc. according to different sensing technologies, among which capacitive touch panels include self-capacitive and mutual-capacitive. [0003] In the special-shaped touch panel, the surface area of ​​the touch electrode at the edge of the special-shaped area in the special-shaped area is different from that in the non-special-shaped area, so that the amount of touch signals generated on the touch panel is uneven, affecting the touch panel. touch accuracy. Contents of the invention [0004] The invention provides a touch panel, a touch display panel and a touch display device, which ca...
