Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only part of the embodiments of the application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0034] During the process of opening the display panel, the cut sidewall is left on the edge of the hole, and water and oxygen can easily penetrate into the display area of ​​the display panel from the cut sidewall, so that the driving layer, light-emitting layer, and packaging layer of the display area are oxidized by moisture, resulting in The display area at the edge of the hole has adverse phenomena such as display black spots and package failure, and the op...

Abstract

The invention discloses a display panel and a preparation method thereof. The display panel comprises a display area, a light-transmitting area and a transition area located between the display area and the light-transmitting area, wherein the light-transmitting area is used for corresponding to a photosensitive element arranged on the side, not provided with a display surface, of the display panel; the display panel comprises an array substrate, a first spiral groove is formed in the position, located in the transition area, of the array substrate, and the first spiral groove surrounds the light-transmitting area and takes the center of the light-transmitting area as the spiral center. The first spiral groove is formed in the transition area, the path of water and oxygen entering the display area through the transition area can be prolonged, and the probability that the light-emitting layer, the packaging layer and the like are affected with damp and oxidized is reduced. Moreover, when the light-transmitting area is formed through cutting, the stress concentration degree can be reduced in the radial direction and the circumferential direction of the first spiral groove at the same time, and therefore the probability that cracks are generated on the display panel under the action of external force is reduced. Therefore, the service life of the display panel can be prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] The rapidly developing display technology has higher and higher requirements for the screen-to-body ratio of the display panel. One solution to increase the screen-to-body ratio is to open a hole in the display panel to form a reserved area for the photosensitive element, but the hole makes the display of the display panel Effectiveness and longevity are affected. Contents of the invention [0003] The technical problem mainly solved by the present application is to provide a display panel, its preparation method, and a display device, which can improve the service life of the display panel. [0004] In order to solve the above technical problems, a technical solution adopted by the application is: [0005] Provided is a display panel, comprising a display area, a light-transmitting a...
