Problems solved by technology

[0005] Embodiments of the present invention provide a display panel and a method for preparing a display panel, which prevent external water and oxygen from entering the panel main body through the cut surface of the panel main body through the water-oxygen barrier layer, thereby avoiding the occurrence of damage caused by erosion and corrosion of the components in the panel main body. The problem of permanent dark spots ensures the encapsulation effect of the panel body and the display effect of the display panel

[0048] The present invention also provides a method for preparing a display panel. The display panel has a display area AA, which includes the following steps:

[0049] S110: Provide a panel body 1 to be processed, the panel body 1 has a display area AA, and cut the panel body 1 to be processed so that a part of the edge of the display area AA forms a cut surface and exposes the functional layer of the panel body 1 to the outside, like Figure 4 to Figure 7 shown, where, Figure 4 and Figure 5 It is a schematic structural diagram and a film layer structure diagram of the panel main body 1 before cutting, Image 6 and Figure 7 It is a schematic structural diagram and a film layer structure diagram of the panel main body 1 after cutting. By comparison, it can be seen that the encapsulation layer 14 of the panel main body 1 in the non-display area NA and the film layer in the display area AA are both cut and removed after cutting.

Abstract

The invention discloses a display panel and a preparation method thereof, and the display panel comprises a panel main body, the panel main body is provided with a display area, a part of the edge of the display area is provided with a cutting surface, and a functional layer of the panel main body is exposed outwards; the adhesive layer covers the cutting surface to shield the functional layer; and the water-oxygen barrier layer at least covers the surface of one side, deviating from the functional layer, of the adhesive layer. The cutting face of the panel body is covered with the adhesive layer so as to shield and protect the functional layer, burrs generated during cutting of the panel body can be filled and leveled up, meanwhile, the adhesive layer can provide flat plane attachment for the water and oxygen blocking layer, it is guaranteed that the water and oxygen blocking layer can be stably attached to the adhesive layer in a covering mode, and the water and oxygen blocking effect is improved. According to the display panel, external water vapor is prevented from entering the panel main body through the cutting surface of the panel main body through the water-oxygen barrier layer, so that the problem that progressive black spots are generated due to erosion and corrosion of components of the functional layer is avoided, and the packaging effect of the panel main body and the display effect of the display panel are ensured.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a display panel and a method for preparing the display panel. Background technique [0002] Organic Light Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, continuously adjustable luminous color, low driving voltage, low energy consumption, low cost, lightness and so on, it is widely used in the field of display technology. has been widely used. With the rapid development and mass production of OLED products, the market demand for display panels of different shapes also increases accordingly. [0003] In some special market requirements, it may be necessary to cut the thin-film encapsulated display panel in the display area, and cut it into the shape of other products with similar dimensions but different outlines (bangs / drops / perforations, etc.). Due to the structural limitation of the exi...
