Problems solved by technology

[0005] The object of the present invention is to provide a display panel and a manufacturing method. By arranging the metal layer and the first elastic layer in the film layer of the bending area in a shape-matched wrinkle shape, the tensile stress borne by the bending area during bending is reduced. Small, which solves the problem that the film layer in the bending area is easily damaged in the prior art

Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises a bending area used for bending the display panel, the bending area comprises a plurality of filmlayers, and the plurality of film layers comprise a substrate, a first elastic layer arranged on the substrate and a metal layer arranged on the first elastic layer. The metal layer comprises a plurality of metal parts, each metal part comprises at least one arch-shaped part, and each arch-shaped part is in an arch shape. The side, close to the metal layer, of the first elastic layer comprises atleast one curved surface, and each curved surface is matched with the side face, close to the first elastic layer, of the corresponding metal part in shape. According to the scheme, the stress borneby the bending area during bending can be reduced, and the fracture resistance of the film layers of the bending area is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode, Organic Light-Emitting Diode) panels can achieve high screen-to-body ratio and narrow borders due to their bending characteristics. [0003] In the existing technology, such as figure 1 As shown, when the angle between the binding area 01 and the display area 02 of the OLED panel is 180°, the strain of the bending area 03 is 0; as the angle between the binding area 01 and the display area 02 increases or decreases Small, the tensile strain or compressive stress of the bending area 03 increases. When the tensile strain or compressive stress of the bending area 03 reaches a certain threshold, the film layer inside the OLED panel will be damaged, so that it cannot ...
