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: 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.
