An electronic device and a driving method therefor. Thicknesses of color resist and a black matrix in a first area, at a corresponding position of a light-transmitting area, of a color film substrate are smaller than the thicknesses of color resist and a black matrix outside the first area, a backlight module is defined with a through hole corresponding to the light-transmitting area, and a photographing module (30) is disposed corresponding to the through hole, so that external light rays can be obtained by means of the through hole and the light-transmitting area, thus under-screen photographing is achieved, and 100% full-screen design is satisfied.
