ABSTRACT:
A backlight control method and apparatus adapted for use in, for example, aircraft passenger entertainment systems are described. The apparatus includes a present brightness/pre-determined brightness and comparator, and a brightness controller which limits present brightness to a selected level in a system deployed in a discrete space (such as a passenger cabin) having a plurality of displays. The method includes steps of comparing present brightness and predetermined brightness and generating one or more control signals to control backlight brightness based on the comparison to provide more uniform brightness in a display system including many displays co-located in a common space.
