Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display function layer and a touch function layer, wherein the touch function layer comprises a bridge-crossing connecting layer, an insulating layer and a touch electrode layer; the bridge-crossing connecting layer comprises a plurality of bridge electrodes; the touch electrode layer comprises a pluralityof first touch electrodes and a plurality of second touch electrodes; the first touch electrode comprises a plurality of first electrode units which are electrically connected with one another; the second touch electrode comprises a plurality of second electrode units which are electrically connected with one another, in the same first touch electrode, any two adjacent first electrode units are electrically connected through a bridge electrode; and each first electrode unit comprises a first electrode part, and the vertical projection of the first electrode part on a plane where the bridge-crossing connecting layer is located is located within the coverage range of the bridge electrode. According to the display panel and the display device provided by the invention, the problem of short circuit between different touch electrodes caused by metal residues is solved, and the normal touch function is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the progress of the information age, the touch screen technology has gradually replaced the key technology to become the mainstream technology of mobile terminals and the like. Touch screen technology is a technology that detects the touched position (in the form of coordinates) and sends it to the CPU when a finger, pen, etc. touch the touch screen installed on the front of the display device, so as to determine the input information. At present, the application range of touch screen is very wide, and the main products include mobile terminals such as touch mobile phones and notebook computers, as well as human-machine display interfaces in the industrial automation industry. [0003] In order to realize the touch function of the display device, it is usually necessary to introd...

AI Technical Summary

Problems solved by technology

[0003] In order to realize the touch function of the display device, it is usually necessary to introduce touch electrodes into the display device, and the different touch electrodes are insulated from each other, which requires disconnection of the touch metal layer, but in the preparation of the touch metal layer During the process, due to the process, there will be some metal residues, which will cause a short circuit between different touch electrodes, thus making the touch function invalid.
