Abstract
A liquid crystal grating includes: a first grating period and a second grating period arranged along a first direction, where a quantity of second electrodes in the second grating period is less than a quantity of first electrodes in the first grating period; a first driving structure, electrically connected with the first electrodes, and controlling the first grating period to form a first light-shielding region and a first light-transmitting region by applying voltages to the first electrodes; and a second driving structure, electrically connected with the second electrodes, and controlling the second grating period to form a second light-shielding region and a second light-transmitting region by applying voltages to the second electrodes, where a width of the second light-transmitting region in the first direction is less than a width of the first light-transmitting region in the first direction.
