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.
