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 method for preparing a display panel. The display panel includes a packaging structure and a device to be packaged, and the area to be packaged of the device to be packaged includes a surface to be packaged and a surface to be packaged adjacent to the surface to be packaged. The protrusion, the chamfered area of acute angle is included between the protrusion to be encapsulated and the surface to be encapsulated, the encapsulation structure includes alternately stacked inorganic layers and organic layers, the inorganic layer includes a first inorganic layer, and the first inorganic layer is in contact with the area to be encapsulated adjacent to each other, and the first inorganic layer completely covers the area to be encapsulated. The display panel mentioned in the embodiment of the present invention not only effectively improves the adhesion between the packaging structure and the device to be packaged, but also fully guarantees the ability of the packaging structure to block water, oxygen and other substances, reducing the damage of the display device by water, oxygen, etc. Risk of material damage.
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...
