Problems solved by technology

In order to adapt to the curved edge of the display panel with special shapes, the display area of ​​the display panel and the touch electrodes need to be designed accordingly, so that the area of ​​the touch electrode block closest to the curved edge of the display panel is smaller than other touch electrode blocks area, resulting in low touch sensitivity of the display panel, this problem needs to be solved urgently

Abstract

The invention provides a touch display panel and a display device. The touch display panel comprises a plurality of touch electrode blocks, a plurality of touch electrode wires; each touch electrode block is electrically connected with at least one touch electrode wire; the different touch electrode blocks are connected with the different touch electrode wires; wherein the edge of a display area of the touch display panel comprises a first special-shaped edge; wherein the plurality of touch electrode blocks comprise a plurality of first touch electrode blocks and a plurality of second touch electrode blocks, and the first touch electrode blocks are touch electrode blocks closest to the first special-shaped edges; wherein the second touch electrode block is other touch electrode blocks except the first touch electrode block; wherein the overlapping area of the first touch electrode block and the plurality of touch electrode wires is a first area; the overlapping area of the second touchelectrode block and the plurality of touch electrode wires is a second area; the first area is larger than the second area. The touch control sensitivity is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a touch display panel and a display device. Background technique [0002] At present, as an information input tool, a display panel with a touch function is widely used in various display products such as mobile phones, tablet computers, and information inquiry machines in halls of public places. In this way, the user only needs to touch the sign on the display panel with a finger to realize the operation of the electronic device, which eliminates the user's dependence on other devices (such as a keyboard and a mouse, etc.), and makes human-computer interaction easier. [0003] In order to meet the market demand, special-shaped display panels appear. The edges of the special-shaped display panels are no longer all composed of straight lines, and the special-shaped display panels also include curved edges. The irregularly shaped display panel is, for example, a di...
