Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] As mentioned in the background, with the development of display technology, touch display devices are increasingly used in various display devices. Nowadays, display devices tend to be thinner and lighter, and the thickness of display devices is getting thinner and thinner, which is one of the inevitable key development directions in the future. The anti-static ability of the existing touch panel needs to be improved.

[0038] Based on this, the embodi...

Abstract

The invention provides a touch panel and a touch display device. The touch panel comprises: a substrate; the first touch electrode and the second touch electrode that are located on the substrate and are arranged in a crossed mode, the first touch electrode comprising a plurality of first sub-electrode blocks arranged in the first direction, the second touch electrode comprising a plurality of second sub-electrode blocks arranged in the second direction, every two adjacent first sub-electrode blocks being connected through a connecting electrode in the first direction, and every two adjacent second sub-electrode blocks being connected through a bridging electrode in the second direction; the conductive protection layer that is connected with the bridging electrode on different layers in an overlapped mode, wherein the conductive protection layer extends along a second direction. By arranging the conductive protection layer which is in different layers with the bridging electrode and is overlapped with the bridging electrode, a coupling capacitor is formed between the conductive protection layer and the bridging electrode and / or the connecting electrode, so that static electricity attracted by the coupling capacitor formed by the bridging electrode and the connecting electrode is shunted, and the static electricity resistance of the bridging electrode and the connecting electrode is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a touch panel and a touch display device. Background technique [0002] A touch display device is a display device that integrates touch control and display, so that the display device has a touch function. Generally, a touch display device can provide a human-computer interaction interface and allow input through a touch medium such as a finger, which is more direct and humanized in use. With the development of display technology, touch display devices are increasingly used in various display devices. Nowadays, display devices tend to be thinner and lighter, and the thickness of display devices is getting thinner and thinner, which is one of the inevitable key development directions in the future. The anti-static ability of the existing touch panel needs to be improved. Contents of the invention [0003] In view of this, the present invention provides...
