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 (S10); 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 using 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.

Abstract: Provided is a method for transmitting image data. The method includes acquiring initial image data of a to-be-displayed image in a display panel, wherein the display panel includes a plurality of pixels, and the initial image data includes pixel data of the plurality of pixels; compressing pixel data of a plurality of first pixels in the initial image data to acquire at least one piece of compressed pixel data, wherein the plurality of first pixels are disposed in a non-foveal region of the display panel, and a plurality of second pixels are disposed in a foveal region of the display panel; sending compressed image data to a driver chip of the display panel, wherein the compressed image data comprises the at least one piece of compressed pixel data and pixel data of the plurality of second pixels.

Abstract: The present disclosure provides a control method for a display panel, a control device thereof, and a display device. This control method includes: obtaining spatial position coordinates of a pupil of a user; determining coordinates of a gaze point in a display area of a display panel viewed by the user according to the spatial position coordinates of the pupil; determining an area range that the pupil of the user is gazing in the display area according to the spatial position coordinates of the pupil, the coordinates of the gaze point and a preset visual angle; determining a gaze area and a non-gaze area in the display area according to the area range, wherein the gaze area is adjacent to the non-gaze area; and adjusting a first gate driving signal input to the gaze area and a second gate driving signal input to the non-gaze area.
