Abstract

The present application provides a grayscale compensation method, a collection device, and a display panel. The grayscale compensation method is applied to a curved screen, and the grayscale compensation method includes: determining a moving trajectory of a shooting unit according to the curvature of the curved screen, wherein the curvature of the moving trajectory satisfies the curvature of the curved screen; controlling the shooting unit to move according to the moving trajectory, and controlling the shooting unit to collect a display screen of the curved screen, and performing grayscale compensation on the curved screen based on the display screen. The technical solution of the present application can effectively reduce the phenomenon of uneven brightness of the display screen of the curved screen.
