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.

Abstract: An audio control method, a control device, a driving circuit and a readable storage medium are provided. The audio control method according to some embodiments of the present disclosure is applicable to the display screen configured with M speakers, and the method includes: obtaining a sound image coordinate of a sound object relative to the display screen; determining N speakers from the M speakers as loudspeakers according to the sound image coordinate and position coordinates of the M speakers relative to the display screen; determining output gains of the N loudspeakers according to distances between the N loudspeakers and a viewer of the display screen and sound attenuation coefficients; and calculating output audio data of the sound object in the display screen according to audio data of the sound object and the output gains of the N loudspeakers, and controlling the M speakers to play the output audio data.
