Abstract

The embodiment of the invention provides a touch display panel and a display device. The touch display device includes a plurality of grid-shaped first touch electrodes and a plurality of grid-shapedsecond touch electrodes. The first touch electrodes include a first sub-touch-electrode and second sub-touch-electrodes. The first sub-touch-electrode is located in a first display region. The secondsub-touch-electrodes are located in a second display region in a first direction. The first sub-touch-electrode is provided with a groove. The second sub-touch-electrodes are not provided with a groove. Any mesh area of a grid on the first sub-touch-electrode is smaller than any mesh area of grids on the second sub-touch-electrodes. After adopting the above-mentioned design, difference between thecross section area of the first sub-touch-electrode and the cross section area of the second sub-touch-electrodes can be reduced, voltage drop difference generated by the first sub-touch-electrode and the second sub-touch-electrodes under the same voltage is enabled to be reduced, and thus sensitivity degrees of the first sub-touch-electrode and the second sub-touch-electrodes are enabled to be roughly the same.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a display device. Background technique [0002] With the development of science and technology, people have more and more diversified demands on the screen of the display device. Therefore, the display area of ​​the display panel is often designed as a shape other than a regular rectangle. For example, in order to make the display device have a higher screen occupation For example, on one side of the display area of ​​the display panel, an opening for avoiding the earpiece or the camera is provided, and the display panel also includes touch electrodes. A gap will be formed on the touch electrode, resulting in a larger voltage drop of the touch electrode compared with other touch electrodes at the same voltage, making the signal on the touch electrode weaker, resulting in a The problem of lower touch sensitivity than other touch electrodes.
