Abstract
A display apparatus has a display region, and the display region includes a texture recognition region. The display apparatus includes: a display panel, a light-shielding layer disposed on a side of the display panel opposite to a light-exit side of the display panel, and a texture recognition structure disposed on a side of the light-shielding layer facing away from the display panel. The light-shielding layer includes a plurality of first through holes. The texture recognition structure is located in the texture recognition region. The texture recognition structure includes a plurality of texture recognition devices arranged in one-to-one correspondence with the plurality of first through holes.
Claims12
A display apparatus having a display region, the display region including a texture recognition region, wherein a size of the texture recognition region is less than a size of the display region;
- the display apparatus comprising:
- a display panel;
- a light-shielding layer disposed on a side of the display panel opposite to a light-exit side of the display panel, the light-shielding layer including a plurality of first through holes located in the texture recognition region and a plurality of second through holes located in a region of the display region other than the texture recognition region, wherein the plurality of first through holes and the plurality of second through holes are arranged in an array, and shapes and sizes of the second through holes are the same as shapes and sizes of the first through holes;
- a texture recognition structure disposed on a side of the light-shielding layer facing away from the display panel, the texture recognition structure being located in the texture recognition region, and the texture recognition structure including a plurality of texture recognition devices arranged in one-to-one correspondence with the plurality of first through holes, wherein a center of the first through hole and a center of the texture recognition device corresponding to this first through hole are on a same vertical line, a shape of the texture recognition device is a circle, and a diameter of the texture recognition device is within a range from 1 μm to 7 μm, inclusive;
- and
- a protective layer disposed on the side of the light-shielding layer facing away from the display panel, wherein
- the light-shielding layer includes a top surface and a bottom surface, and the protective layer directly contacts the bottom surface of the light-shielding layer,
- the texture recognition structure is disposed on a side of the protective layer facing away from the light-shielding layer, and
- the texture recognition structure is located proximate to a side of the protective layer that is facing away from the light-shielding layer.
A manufacturing method of a display apparatus, wherein the display apparatus has a display region, the display region includes a texture recognition region, and a size of the texture recognition region is less than a size of the display region;
- the method comprises:
- manufacturing a display panel;
- arranging a light-shielding layer on a side of the display panel opposite to a light-exit side of the display panel, the light-shielding layer including a plurality of first through holes located in the texture recognition region and a plurality of second through holes located in a region of the display region other than the texture recognition region, wherein the plurality of first through holes and the plurality of second through holes are arranged in an array, and shapes and sizes of the second through holes are the same as shapes and sizes of the first through holes;
- and
- arranging a texture recognition structure on a side of the light-shielding layer facing away from the display panel, the texture recognition structure being located in the texture recognition region of the display apparatus, the texture recognition structure including a plurality of texture recognition devices arranged in one-to-one correspondence with the plurality of first through holes, wherein a center of the first through hole and a center of the texture recognition device corresponding to this first through hole are on a same vertical line, a shape of the texture recognition device is a circle, and a diameter of the texture recognition device is within a range from 1 μm to 7 μm, inclusive;
- wherein
- arranging the light-shielding layer on the side of the display panel opposite to the light-exit side of the display panel, includes:
- providing a protective layer, and manufacturing the light-shielding layer on a side of the protective layer by using a patterning process, wherein the light-shielding layer includes a top surface and a bottom surface, and the protective layer directly contacts the bottom surface of the light-shielding layer;
- applying a transparent adhesive layer on a side of the light-shielding layer facing away from the protective layer;
- and
- bonding a side of the transparent adhesive layer facing away from the light-shielding layer to the side of the display panel opposite to the light-exit side of the display panel;
- arranging the texture recognition structure on the side of the light-shielding layer facing away from the display panel includes:
- arranging the texture recognition structure on a side of the protective layer facing away from the light-shielding layer, wherein the texture recognition structure is located proximate to a side of the protective layer that is facing away from the light-shielding layer.
