Abstract

A light emitting display device comprising: a sensing means for sensing a brightness of ambient light; and a processing means for mapping input pixel brightness levels to output pixel brightness levels for use in driving an output of the display device, wherein the processing means varies the mapping in response to the sensed ambient light brightness, such that a spacing between adjacent lower output pixel brightness levels is increased and a spacing between adjacent higher output pixel brightness levels is decreased in response to an increase in the sensed ambient light brightness.
