Disclosed is a pixel circuit structure (20), comprising: a substrate (SS); a to-be-contacted portion (200) provided at a first side (S1) of the substrate (SS) and used for accepting a contact of a finger; and a capacitance detection circuit (CS) provided on a second side (S2) of the substrate, coupled to the to-be-contacted portion (200), and used for detecting a capacitance between the to-be-contacted portion (200) and the finger. A capacitance detection circuit (CS) and a to-be-contacted portion (200) are provided on different sides of a substrate (SS) by a pixel circuit structure (20), so that the parasitic capacitance (CP2) can be effectively reduced, and a fingerprint signal is relatively significant, thereby enhancing the accuracy of fingerprint recognition.
