|Title:||ARRAY PANEL AND DRIVE METHOD THEREOF, DISPLAY PANEL AND DISPLAY DEVICE|
An array panel and drive method thereof, a display panel and a display device. The array panel comprises: a substrate (1), and a plurality of pixel units (2) and a plurality of fingerprint recognition units (3) located on the substrate (1). Each of the pixel units (2) comprises a plurality of sub-pixel units (20) having different color filters. Each of the sub-pixel units (20) and each of the fingerprint recognition units (3) are arranged in a matrix in orthographic projection on the substrate (1). During a display time interval, the fingerprint recognition units (3) serve as pixel units (2). During a fingerprint recognition time interval, the sub-pixel units (20) are turned off, fingerprint recognition scan lines are configured to sequentially receive scan signals, and the fingerprint recognition units (3) are configured to read, via fingerprint recognition read lines, fingerprint recognition signals, and detect current signals corresponding to the fingerprint recognition signals coupled to the fingerprint recognition units (3). Therefore, the embodiment can prevent a problem of interference between the fingerprint recognition signals and the display signals.
