Abstract
A texture recognition pixel circuit includes a photosensitive sub-circuit, a potential raising sub-circuit and a driving output sub-circuit. The photosensitive sub-circuit is configured to, under control of a first voltage transmitted by a first voltage terminal and a potential of the reading node, sense an optical signal including texture information, convert the optical signal into a first detection signal, and transmit the first detection signal to a reading node. The potential raising sub-circuit is configured to, due to an action of a second voltage signal transmitted by a second voltage signal terminal, raise the potential of the reading node. The driving output sub-circuit is configured to, due to an action of the first detection signal that is raised, a third voltage signal transmitted by a third voltage signal terminal and a fourth voltage signal transmitted by a fourth voltage signal terminal, generate and output a second detection signal.
