  • Patent number: 11150505
    Abstract: Display panel and display device are provided. The display panel includes: a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The first substrate includes a first base substrate and an optical sensor disposed on the first base substrate. The second substrate includes a second base substrate, a black matrix disposed on the second base substrate, and a light collecting structure disposed on a side of the black matrix adjacent to the first substrate. The optical sensor and the light collecting structure overlap each other in a direction perpendicular to the display panel. The light collecting structure includes at least one transparent protrusion protruded along a direction perpendicular to a surface of the first or second substrate and from the second substrate to the first substrate. The light collecting structure has a refractive index larger than the liquid crystal layer.

  • Patent number: 10665631
    Abstract: A display panel includes an array substrate and a color film substrate. The array substrate includes a plurality of light-sensing elements. The color film substrate includes a first substrate, a first light-shielding layer, and at least one second light-shielding layer. The first light-shielding layer is located on a side of the first substrate adjacent to the array substrate, and includes a plurality of first hollowed regions. The at least one second light-shielding layer is located on a side of the first light-shielding layer adjacent to the array substrate, and includes a plurality of second hollowed regions. In a direction perpendicular to the first substrate, orthogonal projections of the plurality of first hollowed regions, the plurality of second hollowed regions, and the plurality of light-sensing elements overlap with each other. A first flat layer is disposed between the first light-shielding layer and the at least one second light-shielding layer.
