Problems solved by technology

With the development of smart wearable devices, touch devices with non-rectangular (special-shaped) shapes such as circles and octagons are more and more popular with users. Matching, resulting in incomplete or uneven coverage of the touch electrodes on the edge of the panel, which reduces the touch accuracy and cannot meet user needs

Abstract

The embodiment of the invention discloses a touch display panel and a display device. The touch display panel comprises a plurality of first touch electrodes which are insulated from one another and are concentrically arranged; The plurality of second touch electrode groups and the plurality of first touch electrodes are concentrically arranged, each second touch electrode group surrounds one first touch electrode, and the first touch electrodes and the second touch electrode groups are insulated from each other; Each second touch electrode group comprises a plurality of second sub-touch electrodes which are sequentially arranged in the direction of the first touch electrodes in an insulating manner; and the areas of the second sub-touch electrodes are equal. According to the embodiment ofthe invention, the problem of low touch sensitivity caused by incomplete coverage of the touch electrodes at the edge of the non-rectangular touch display panel is solved, the touch sensitivity of the edge of the non-rectangular touch display panel is effectively improved, and the risk of touch failure is reduced.

Description

technical field [0001] Embodiments of the present invention relate to touch display technology, and in particular, to a touch display panel and a display device. Background technique [0002] The touch display panel can generally be divided into a self-capacitive touch display panel and a mutual-capacitance touch display panel according to its touch control principle. Since the mutual capacitive touch display panel can realize multi-point touch, the mutual capacitive touch display panel has become the mainstream in the current capacitive touch display market. [0003] Since the existing touch electrodes are mostly quadrilaterals of the same size (such as rectangles, rhombuses, etc.), the touch driving electrodes and touch sensing electrodes are respectively arranged on the substrate along the X and Y directions perpendicular to each other to form a touch pattern. . Since the driving electrodes or the sensing electrodes on the rectangular substrate are equidistantly arrange...
