An electronic device (100) and a driving method therefor. The color resistance and the thickness of a black matrix in a first area (120), at a corresponding position of a light-transmitting area (110), of a color film substrate (102) are smaller than color resistance and the thickness of the black matrix outside the first area (120), a backlight module (20) is provide with a through hole (210) opposite to the light-transmitting area (110), and a photographing module (30) and the through hole (210) are oppositely provided, so that external light rays can be obtained by means of the through hole (210) and the light-transmitting area (110), thus under-screen photographing is achieved, and 100% full-screen design is satisfied.
