摘要:
A texture recognition apparatus and an opposite substrate are provided. The texture recognition apparatus includes a light source array, an image sensor array and a light shielding layer. The light source array includes a plurality of light sources; the image sensor array includes a plurality of image sensors, an orthographic projection of the light shielding layer on a plane where the light source array is located is between two adjacent light sources, an orthographic projection of the light shielding layer on a plane where the image sensor array is located at least partially overlaps with the plurality of image sensors; the light shielding layer has at least one opening, and at least a part of an orthographic projection of the first opening on the plane where the image sensor array is located is at least on one side of the first image sensor or overlaps with the first image sensor.
