Problems solved by technology

[0002] With the development of display technology, the existing display panels tend to be more and more full-screen. However, since the camera, earpiece and other components need to be placed on the front of the screen, slots or holes will be made in the full screen, resulting in grooving or digging. The shape of the touch electrode in the hole area is different from that of other areas, and the touch accuracy is reduced, which cannot meet the demand for touch accuracy.

Abstract

The embodiment of the invention discloses a touch display panel and a touch display device. The touch display panel comprises a touch panel, the touch panel includes a substrate and a plurality of first touch electrode blocks and a plurality of second touch electrode blocks arranged on the substrate, In the direction perpendicular to the substrate, the first touch electrode block and the second touch electrode block are not overlapped; The touch display panel comprises a special-shaped area and a non-special-shaped area. The opposite areas of the opposite surfaces of the adjacent first touch electrode block and second touch electrode block in the special-shaped region are different from the opposite areas of the opposite surfaces of the adjacent first touch electrode block and second touchelectrode block in the non-special-shaped region; and / or the distance between the adjacent first touch electrode block and second touch electrode block in the special-shaped area in the direction parallel to the substrate is different from the distance between the adjacent first touch electrode block and second touch electrode block in the non-special-shaped area in the direction parallel to thesubstrate. The embodiment of the invention ensures that the touch display panel has higher touch detection precision.

Description

technical field [0001] Embodiments of the present invention relate to touch display technology, and in particular, to a touch display panel and a touch display device. Background technique [0002] With the development of display technology, the existing display panels tend to be more and more full-screen. However, since the camera, earpiece and other components need to be placed on the front of the screen, slots or holes will be made in the full screen, resulting in grooving or digging. The shape of the touch electrode in the hole area is different from that of other areas, and the touch accuracy is reduced, which cannot meet the demand for touch accuracy. Contents of the invention [0003] The present invention provides a touch display panel and a touch display device to ensure that the touch display panel has higher touch detection accuracy. [0004] In a first aspect, an embodiment of the present invention provides a touch display panel, including: [0005] A touch p...
