Abstract: A display device and a method for driving the same are provided. Touch electrode groups of a display panel of the display device correspond to the touch switch groups in one-to-one correspondence, each touch electrode group includes d touch electrodes subgroups arranged in a first direction, each touch switch group includes multiplexers, and each multiplexers includes m input terminals, and n output terminals electrically connected to the touch electrodes in one-to-one correspondence, where d=n/m. One touch analog front end group corresponds at least two touch pin groups. In one touch pin group and one touch analog front end group corresponding thereto, every two touch analog front ends are electrically connected to a same number of the touch pins. In one touch pin group and one touch switch group corresponding thereto, every two touch pins are electrically connected to a same number of the input terminals.

Abstract: A display panel includes an array substrate, a protective cover, a fingerprint identification circuit, and an optical structure. The array substrate and the protective cover are disposed oppositely, where the protective cover is located at a light exiting side of the array substrate. The fingerprint identification circuit is located at a side of the array substrate facing away or toward the protective cover and is configured to receive detection light and perform a fingerprint detection according to the detection light. The optical structure is located at a side of the protective cover facing away from the array substrate and is configured to increase a reflection amount of the detection light received by the fingerprint identification circuit.
