COVER PLATE STRUCTURE, MANUFACTURING METHOD THEREFOR, DISPLAY DEVICE AND WEARABLE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159421
Kind Code:
A1
Abstract:
A cover plate structure, a preparation method therefor, a display device, and a wearable display device. The cover plate structure comprises: a cover plate (10), which is provided with a light-transmitting area and an edge area arranged in a circumferential direction around the light-transmitting area, and a recess (11) which is provided in the edge area of one side of the cover plate (10). The recess (11) is arranged in the circumferential direction around the light-transmitting area. The surface of the recess (11) is provided with a first microstructure, and the first microstructure comprises at least one of a first protrusion (12) and a first groove (13). In the cover plate structure, the light-transmitting area is arranged such that the display module displays in the light-transmitting area. The recess (11) is arranged to facilitate the cooperative installation of the cover plate (10) and a frame body (30). The surface of the recess (11) is provided with the first microstructure which comprises at least one of the first protrusion (12) and the first groove (13). The first microstructure is provided on the recess (11) to increase the dyne value of the surface of the recess (11), such that the recess (11) and the frame body (30) are more tightly fitted, the sealing performance can be effectively ensured, and the problem of poor sealing effects caused by the pollution of the surface of the recess (11) is avoided.
