Abstract: The present application discloses a display optimization method. The method includes setting a light-emitting substrate including a first plurality of unit regions. Each unit region is associated with a luminance produced by one or more light-emitting diodes. The method further includes determining a sensitive area having a second plurality of unit regions in part of the light-emitting substrate in association with eyeball position of viewer relative to the light-emitting substrate and a non-sensitive area having a plurality of combined-regions in remaining part of the light-emitting substrate. Additionally, the method includes transferring local variables including information about the sensitive area and the combining factor k to a processor. Furthermore, the method includes operating the processor based on the local variables to individually control a first luminance of the one unit region in the sensitive area and to commonly control a second luminance of one combined-region in the non-sensitive area.
