Abstract: Provided in the present disclosure are a driving method for a liquid crystal grating, and a display apparatus and a display method for a display apparatus. The driving method for a liquid crystal grating comprises: determining the real-time position of the center of a pupil; according to the real-time position, and a pre-established correspondence between the position of the center of the pupil and the position of a light-transmitting region in a liquid crystal grating, determining the position of the light-transmitting region in the liquid crystal grating that corresponds to the real-time position; and driving the liquid crystal grating, such that the liquid crystal grating only transmits light at the position of the light-transmitting region that corresponds to the real-time position.
