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.
