Title:
DISPLAY PANEL, DISPLAY DEVICE AND METHOD FOR PREPARING DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2024/027776
Kind Code:
A1
Abstract:
A display panel (10), a display device and a method for preparing the display panel (10). The display panel (10) comprises a substrate (100), a padded layer (300) disposed on the substrate (100), a light-emitting layer (400), and an encapsulation layer (500) disposed on the side of the light-emitting layer (400) away from the substrate (100). The padded layer (300) comprises a first subdivision (310) and a second subdivision (320). The second subdivision (320) is located on the side of the first subdivision (310) facing the substrate (100), and an orthographic projection area of the first subdivision (310) on the substrate (100) is larger than an orthographic projection area of the second subdivision (320) on the substrate (100), that is, the second subdivision (320) is recessed relative to the first subdivision (310) to form a groove (340). A first encapsulation portion (510) is deposited within an isolation space (330), at least part of the first encapsulation portion (510) being located within the groove (340). Then, a second encapsulation portion (520) is prepared on the side of the first encapsulation portion (510) away from the substrate (100), and the second encapsulation portion (520) is prepared on the entire surface, has relatively good coating properties and further improves the overall encapsulation performance of the encapsulation layer (500). The first encapsulation portion (510) and the second encapsulation portion (520) are prepared in steps, which can solve the problem of the encapsulation performance of the encapsulation layer (500) being reduced due to the formation of holes between the encapsulation layer (500) and the padded layer (300).
