Problems solved by technology

[0004] In order to realize the touch function of the display device, it is usually necessary to introduce touch electrodes into the display device, and different touch electrodes are insulated from each other, which requires disconnection of the touch metal layer, but if the disconnection density is uneven or the position is different , it will affect the display effect of the display device

Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display layer and a touch control layer which are arranged ina stacked mode, and at least one first touch control electrode, wherein the display layer comprises a plurality of pixel units formed by a plurality of sub-pixels; the touch control layer comprises across-bridge layer, an insulating layer and a touch control metal layer; the touch control metal layer comprises a plurality of metal grid units, and the metal grid units are arranged corresponding to the pixel units; and the first touch control electrode comprises a plurality of metal grid units, and every two adjacent metal grid units are electrically connected through a connecting lead. The first touch control electrode is divided into a plurality of mutually-disconnected metal grid units on the touch control metal layer, so that the edge position and the interior of the first touch control electrode are subjected to the same disconnection treatment, and therefore the possibility that the display effect is poor due to uneven disconnection density or different positions can be lowered,and the display effect of the display panel is further improved; and meanwhile, the fingerprint identification under an optical screen is highly facilitated.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED) has become a very popular flat-panel display industry at home and abroad, and has been hailed as the next-generation "star" flat-panel display technology, mainly because OLED has self-luminescence, Wide viewing angle, fast response time, high luminous efficiency, thin panel thickness, large-size and bendable panels can be produced, simple manufacturing process, and low cost. [0003] In addition, the touch screen technology has gradually replaced the button 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 de...
