Abstract: A display apparatus and a driving method therefor. The driving method includes: determining a gaze area and a non-gaze area of a user on a display apparatus in real time; and driving the gaze area for image displaying at a first resolution, and driving the non-gaze area for image displaying at a second resolution, wherein the first resolution is higher than the second resolution. By means of the display apparatus, image resolution can be adjusted according to different areas, so as to realize high-resolution image display in a display area at which a user gazes and realize low-resolution image display in other areas, thereby reducing power consumption and achieving reasonable allocation of resources on the premise of ensuring the user experience.
