Abstract

The embodiment of the invention provides a touch display panel and a touch display device, which relate to the technical field of display and are used for improving the bending performance of touch electrodes and further improving the working stability of the touch display panel. The touch display panel comprises a substrate, wherein the substrate comprises a display region and a non-display region, the display region comprises a bent region, the non-display region comprises an upper non-display region and a lower non-display region, and the lower non-display region is provided with a chip binding region. The bending area is provided with touch electrodes, and each touch electrode comprises a plurality of touch electrode blocks. In one touch electrode, two adjacent touch electrode blocks are electrically connected through a connection part. The display area is provided with a plurality of first touch signal lines, and at least part of the touch electrodes are connected with the first touch signal lines. The lower non-display area is provided with a plurality of second touch signal lines one-to-one correspondingly connected with a plurality of first touch signal lines, and the second touch signal lines are also connected with the chip binding area. The touch display panel is used for realizing screen display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. 【Background technique】 [0002] With the continuous development of touch display technology and the diversified demands of users for touch display devices, bendable and foldable touch display panels have been more and more widely used. [0003] A plurality of touch electrodes are arranged in the display area of ​​the touch display panel, and each touch electrode has a planar structure. However, for a bendable and foldable touch display panel, as the number of bendings increases, the touch electrodes may break, resulting in the inability of the touch electrodes to detect touch accurately and affecting the normal operation of the touch display panel. . 【Content of invention】 [0004] In view of this, the embodiments of the present invention provide a touch display panel and a touch display device, which are used to im...
