Abstract

The invention relates to a display difference correction method and device for an immersive LED display screen, and the method comprises the steps: measuring the brightness values displayed by all display surfaces in the LED display screen at different observation angles, and obtaining the mapping relation between the brightness values and the observation angles; determining the visual range of the user on each display surface according to the size of each display surface and the sight height of the user; determining a target observation angle and a target brightness value contained in the view range in each display surface according to the mapping relation; determining a target correction coefficient of each display area on the display surface according to the minimum target brightness value and the original brightness value of each lamp point; and correcting the lamp points in each display area according to the target correction coefficient. The brightness of each display area in the view range of a user can be corrected according to the view range of the user for each display surface and the mapping relation between the observation angle and the display brightness, and the display effect of the immersive LED display screen is improved.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of display effects of LED display screens, and in particular, to a display difference correction method and device for an immersive LED display screen.
