Display panel, display apparatus and preparation method for display panel

Abstract

The invention discloses a display panel, a display apparatus and a preparation method for the display panel. The display panel comprises a substrate, an organic light emitting device, a thin film packaging layer, and a metal layer, wherein the substrate comprises a display region and a non-display region; the organic light emitting device is arranged in the display region of the substrate; the thin film packaging layer covers the organic light emitting device; the metal layer is positioned in the non-display region of the substrate; grooves are formed in the metal layer; and the grooves are filled with an organic layer. By virtue of setting the metal layer in the non-display region of the substrate, forming the grooves in the metal layer and filling the grooves with the organic layer, bending stress resistance and cutting stress resistance of an edge region are improved, so that risk of cracks on the edge is relieved, and crack expansion can be effectively prevented.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device including the display panel, and a manufacturing method of the display panel. Background technique [0002] With the continuous development of display technology, the display panel manufacturing technology is becoming more and more mature. Existing display panels mainly include Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), A plasma display panel (Plasma Display Panel, PDP) and the like. The flexible display panel is a deformable and bendable display panel made of materials such as polyimide or polyester film. Compared with the traditional display panel, the flexible display panel has the advantages of small size, low power consumption, With the advantages of being bendable and flexible, it is a display panel with broad application prospects. [0003] Existing flexible display panels usually use thin film packaging ...

Problems solved by technology

Because the inorganic layer has a dense film structure, it mainly plays the role of blocking water and oxygen, but because the elastic modulus of the inorganic layer is small, bending cracks or cutting cracks are prone to occur, so an organic layer is arranged between the inorganic layers to relieve the inorganic layer. interlayer stress, figure 1 It is a structural schematic diagram of a display panel in the prior art, including a substrate 10', an organic light-emitting device 20' and a thin film encapsulation layer 30', wherein the thin film encapsulation layer 30' includes a first inorganic encapsulation layer 31', an organic encapsulation layer 32' In direct contact with the second inorganic encapsulation layer 33', the two inorganic encapsulation layers 31' and 33' are in direct contact with the edge area 1 of the display panel. As the number of times of bending of the flexible display panel increases, cracks are more likely to occur in this area, affecting Encapsulation effect
