Abstract

An embodiment of the invention discloses a display panel and a display device. The display panel comprises a touch function layer and a first flexible printed circuit board electrically connected withthe touch function layer, the touch function layer comprises a first bending portion, the first bending portion is positioned in a special-shaped area, the touch function layer passes a fourth edge and extends towards a non-display area from a display area to form the first bending portion, and the first flexible printed circuit board is bound to the first bending portion, passes the first bending portion and is bent to one side of the display panel opposite to a light emitting surface of the display panel from the special-shaped area. The display panel solves the problems that a frame is further narrowed and limited, and wiring on the bending portion has short circuit and circuit breaking risks. Screen-to-body ratio is further increased, and the working reliability of the display panel is further improved.

Description

technical field [0001] The present invention relates to display technology, in particular to a display panel and a display device. Background technique [0002] As display screens are used more and more widely, widescreen technology has become an important technical item. At the same time, the technology of narrow borders of display panels is also becoming more and more important. Advanced electronic products, especially portable electronic products, tend to be more and more narrow bezel design. [0003] In order to increase the screen-to-body ratio of electronic products, the non-display area on the display panel is compressed smaller and smaller. For example, in the display screen of a mobile phone, in order to compress the non-display area as much as possible, a gap (special-shaped area) has been set at the upper end of the display area, and the front camera and handset of the mobile phone and other devices are arranged in the gap. For another example, by bending the pa...
