Abstract

The invention provides a display panel and a preparation method of a packaging structure of the display panel. The display panel comprises a side packaging structure and a surface packaging structure. The side packaging structure is located in a non-display area of the display panel. The side packaging structure comprises a first frame adhesive and a second frame adhesive. The second frame adhesive is arranged close to a display area of the display panel. A protruding part is formed on the side, facing the second frame adhesive, of the first frame adhesive, and a recessed part in embedding fit with the protruding part is formed in the position, corresponding to the protruding part, of the second frame adhesive. Compared with an existing packaging structure, the main frame adhesive and the corner frame adhesive of the first frame adhesive of the non-display area are designed in different regions, under the condition that the width of the non-display area is not increased, a water and oxygen invasion path is prevented, the water resistance of materials is improved, the failure time of devices is delayed, the problem that the four corners of the display panel and the peripheral center of the frame are prone to failure is solved, the packaging effect is enhanced, water and oxygen are prevented from invading the light-emitting device layer from the four corners, and the service life of the display panel is further prolonged.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a display panel and a method for preparing a package structure of the display panel. Background technique

[0002] Compared with liquid crystal display panels, the existing OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel has fast response speed, good viewing angle characteristics, thinner and thinner, and excellent color gamut performance. It is gradually becoming the preferred new display technology for the next generation.

[0003] The OLED display panel mainly includes a substrate and a light-emitting device on the substrate. The light-emitting device mainly recombines holes and electrons between the anode and the cathode in the light-emitting layer to form excitons in an excited state, and then releases energy in the form of light or heat. Back to ground state. The life of the light-emitting device is mainly affected by the surrounding gas en...
