Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] In the prior art, the bonding between the packaging structure of the display panel and the device to be packaged (that is, the display device) is mainly achieved by using an adhesive material. Therefore, in the actual bending process, the packaging structure and the device to be packaged are extremely tight. Separation between layers is prone to occur, thereby greatly reducing the encapsulation capability of the encapsulation structure.

The invention provides a display panel, a display device and a display panel preparation method. The display panel comprises a packaging structure and a to-be-packaged device; a to-be-packaged area ofthe to-be-packaged device comprises a to-be-packaged surface and a to-be-packaged bulge adjacent to the to-be-packaged surface; an acute angled chamfering area is arranged between the to-be-packagedbulge and the to-be-packaged surface; the packaging structure comprises an inorganic layer and an organic layer alternately laminated with the inorganic layer; the inorganic layers comprise a first inorganic layer; the first inorganic layer is adjacent to the to-be-packaged area; and the first inorganic layer completely covers the to-be-packaged area. The display panel provided by the embodimentsnot only effectively improves the adhesion force between the packaging structure and the to-be-packaged device, but also sufficiently ensuring the ability of blocking substances such as water and oxygen by the packaging structure, thereby reducing the risk that display devices are damaged by the substances such as water and oxygen.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a display device and a method for preparing a display panel. Background technique [0002] Because Organic Light-Emitting Diode (OLED) has the characteristics of self-luminescence, short response time, high luminous efficiency, flexible panels, and wide color gamut, it is often applied to display devices with flexible bending capabilities. . However, OLED display devices are prone to failure after being affected by substances such as water and oxygen, so a good packaging structure is required for protection. [0003] However, since both the existing packaging structure and the OLED display device include multiple film layers, and the adhesion between the existing packaging structure and the OLED display device is weak, in the actual bending process, the existing packaging structure It is very easy to have interlayer separation between OLED and OLED display dev...
