Texture recognition device and display apparatus

A texture recognition device, having a plurality of pixel units, and comprising:

• a base substrate,
• a driving circuit layer on the base substrate,
• a first electrode layer on a side of the driving circuit layer away from the base substrate, and a photosensitive element layer on a side of the first electrode layer away from the base substrate,
• wherein at least one of the plurality of pixel units comprises a pixel driving circuit in the driving circuit layer, a first electrode in the first electrode layer, and a plurality of photosensitive elements spaced apart from each other in the photosensitive element layer,
• the pixel driving circuit is electrically connected with the first electrode,
• the plurality of photosensitive elements are on a side of the first electrode away from the base substrate, and are electrically connected with the pixel driving circuit through the first electrode.
