1. A texture recognition apparatus, having a touch side surface, and comprising:
a light source array, comprising a plurality of light sources;
an image sensor array, comprising a plurality of image sensors, wherein the plurality of image sensors are configured to be able to receive light emitted from the plurality of light sources and reflected by a texture to the plurality of image sensors for texture image collection,
a light shielding matrix, on a light incident side of the image sensor array, comprising a plurality of light shielding patterns arranged in an array,
wherein each of the plurality of image sensors comprises a photosensitive element; in a direction perpendicular to the touch side surface, the plurality of light sources do not overlap with the plurality of light shielding patterns; and a photosensitive element of each of the plurality of image sensors at least partially overlaps with at least one of the plurality of light shielding patterns, and
the texture recognition apparatus further comprising a light shielding layer between the light shielding matrix and the image sensor array, wherein the light shielding layer comprises a plurality of first openings,
in the direction perpendicular to the touch side surface, a photosensitive element of each of the plurality of image sensors at least partially overlaps with at least two of the plurality of first openings; and the plurality of light shielding patterns are in one-to-one correspondence and at least partially overlap with the plurality of first openings.
