Document Type and Number:
WIPO Patent Application WO/2022/156299
Kind Code:
A1
Abstract:
Provided is a display panel, comprising: a substrate; a light-emitting structure, which is located on a side of the substrate; an encapsulation layer, which is located on the side of the light-emitting structure that faces away from the substrate; a photoelectric sensing structure, which is located on the side of the encapsulation layer that faces the substrate; at least one of a touch-control function layer and a color film layer, which is located on the side of the encapsulation layer that faces away from the substrate, wherein the touch-control function layer comprises a first metal layer structure, a touch-control insulating layer and a second metal layer structure, which are arranged in a stacked manner in the normal direction of a plane where the substrate is located, and the color film layer comprises a black matrix; and a collimating light path structure, which is located on the side of the photoelectric sensing structure that faces away from the substrate, and comprises at least two light-shielding layers, wherein each light-shielding layer has light-transmitting holes, which are arranged in an array, the light-transmitting holes in the light-shielding layers correspond to each other on a one-to-one basis, orthographic projections of the light-transmitting holes on the substrate are at least partially overlapped, the at least two light-shielding layers comprise at least one first light-shielding layer, which is located on the side of the encapsulation layer that faces away from the substrate, and the first light-shielding layer is arranged on the same layer as the first metal layer structure, the second metal layer structure, the touch-control insulating layer or the black matrix.
