Display panel, bending method of display panel and display device

Abstract

The invention discloses a display panel, a bending method of the display panel and a display device. The display panel includes a display region, a wire arrangement region, and a bending region used for connecting the display region with the wire arrangement region. The bending region includes a first edge and second edges, the first edge refers to the edge on which the bending region is connectedwith the display region or the wire arrangement region, and the second edges refer to the edges, besides the first edge, of the bending region; at least one second edge includes inflection points, and the second edges are concaved toward the inside of the bending region at the positions of the inflection points. According to the display panel, at least one second edge of the bending region includes the inflection points, the second edges are concaved toward the inside of the bending region at the positions of the inflection points, thus the width, at the inflection points, of the bending region is thus very small, the inflection points easily become bending centers, and the situation that the bending centers are formed on the border of a protection layer is avoided; the stress effect applied by the protection layer on metal wires in the bending region in the bending process is reduced, and thus breaking of the metal wires in the bending region can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, its bending method and a display device. Background technique [0002] With the development of display technology, the application of display technology is becoming more and more extensive. Among them, Organic Light-Emitting Diode (OLED) display has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, thin and light, etc. Therefore, OLED displays are widely used. [0003] Such as Figure 1a As shown, the polyimide (Polyimide, PI) substrate of the OLED display is provided with a display area A and a wiring area B, and the width of the wiring area B is relatively wide. B is bent to fold the wiring area B to the back of the display area to reduce the width of the frame. A bending area C can be set between the display area A and the wiring area B, so as to fold the wiring area B to the back of the display area, but...
