Title:
DISPLAY PANEL, PREPARATION METHOD FOR DISPLAY PANEL, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/236364
Kind Code:
A1
Abstract:
Disclosed in the present application are a display panel, a preparation method for a display panel, and a display apparatus. The display panel is provided with a first display area, and a second display area, which at least partially surrounds the first display area, wherein the light transmittance of the first display area is greater than the light transmittance of the second display area. The display panel comprises: a base, which comprises at least two sub-base layers arranged in a stacked manner; a light-shielding layer, which is at least partially located in the first display area, is arranged between any two adjacent sub-base layers, and comprises a patterned first opening; and a conductive layer, which is arranged at one side of the base, and is provided with a second opening corresponding to the first opening. The sub-base layers serve as planarization layers of the light-shielding layer, and the flatness of the sub-base layers is good, such that the overall thickness of the display panel is guaranteed, and a production process is also simplified, thereby reducing the cost. The sub-base layers can effectively absorb the stress generated due to folding or bending of the light-shielding layer, such that the stress of the light-shielding layer itself can be better released, and the light-shielding layer has a better reliability performance.
