Abstract: A display substrate and a display device are disclosed. The display substrate includes a base substrate and a plurality of shift register units; each of the plurality of shift register units includes an input circuit, an output circuit, a first reset circuit and a frame reset signal connection wire; the frame reset signal connection wire and is configured to provide a frame reset signal to the first reset circuit; the first reset circuit is configured to respond to the frame reset signal, so as to reset a first node and an output end within a time period between two display frames of the display substrate; the first reset circuit includes a first transistor and a second transistor, and the frame reset signal connection wire, a gate of the first transistor and a gate of the second transistor are provided on a first conductive layer.

Abstract: A print recognition module, a method for driving the same, and a display device are disclosed, where a synchronous scan component is added above a sensing surface of a photo sensor array, and the synchronous scan component can be divided into a first light shielding area and a first light transmitting area, both of which are varying dynamically; where the first light transmitting area is formed at least above a photo sensor being scanned to recognize a print, and the first light shielding area can shield the other photo sensors than the photo sensor being scanned to recognize the print, so that these photo sensors will not be illuminated by any light; and as the photo sensors are being scanned, the first light shielding area and the first light transmitting area, in the synchronous scan component are varying in synchronization therewith.
