Abstract: A near-eye display includes a display configured to display images, a memory device storing a compensation profile for compensating perceived brightness nonuniformity (e.g., brightness roll-off) of the display, and a display controller for controlling operations of the display. The compensation profile includes compensation values for modifying brightness in regions of the display to compensate the perceived brightness nonuniformity. The display controller is configured to control brightness of the display based on the compensation profile.
