Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a 3D cover plate for preventing ink jagged edges of a display area. Background Art
[0002] Since the 3D cover plate is to be equipped with a display screen, there is a hollow area in the middle that does not need to be printed with ink, and the other parts need to be printed with light-shielding ink. However, since the edges of the 3D cover plate are usually irregular curved surfaces, this structure makes it impossible to use a screen printing method for direct printing. Some solutions use a film to mask the lower surface of the 3D cover plate, which will cause the ink on the edge of the display area to be jagged or deformed, seriously affecting the quality and yield.
