Title: DISPLAY DEVICE FOR SURFACE TEXTURE RECOGNITION
Abstract:
A display device for surface texture recognition comprises a base substrate (10) and a contact board (20) that are overlapped with each other. The contact board (20) is specifically comprises: a first surface (S1) in contact with a textured surface, the first surface (S1) being located on one side of the contact board (20) back away from the base substrate (10), multiple pixel units (P) located between the base substrate (10) and the contact board (20), at least one pixel unit (P) comprising a photosensitive element (12) located on the base substrate (10); a light concentration element (13), located between the photosensitive element (12) and the contact board (20); and a light shading element (14), located between the light concentration element (13) and the photosensitive element (12), the light shading element (14) being provided with a light transmission hole (H), so that light passing through the contact board (20) and the light concentration element (13) penetrates through the light transmission hole (H) and reaches the photosensitive element (12).
