Abstract
A texture recognition assembly (100) includes: a substrate (1); an optical sensing structure (2) on the substrate; and a light path structure (3) on a side of the optical sensing structure distal to the substrate and including an inclined light transmitting channel (Q) such that light incident on the light path structure can only pass through the light transmitting channel. The light path structure includes at least two light shielding layers (31, 31a, 31b, 31c) and a light transmitting layer (32, 32a, 32b) located between any adjacent two of the at least two light shielding layers, the light shielding layer (31a) closest to the optical sensing structure includes a first light transmitting hole (311a), the light shielding layer (31b) farthest away from the optical sensing structure includes a second light transmitting hole (322b), the first light transmitting hole and the second light transmitting hole define the light transmitting channel.
