Claim Text:
1. A pixel luminance compensating unit configured to receive input-data comprising an input luminance curve having a plurality of luminance values measured from pixels of a display panel during light emission and to process the input-data prior to generating output-data, the compensating unit comprising: an uncompensated gray-level region processing unit configured to generate first output-data by processing first input-data corresponding to a first portion of the measured input luminance curve corresponding to an uncompensated gray-level region; a compensated gray-level region processing unit configured to generate second output-data by processing second input-data corresponding to a second portion of the measured input luminance curve corresponding to a compensated gray-level region; and an interpolated gray-level region processing unit configured to generate third output-data by processing third input-data corresponding to a third portion of the measured input luminance curve corresponding to an interpolated gray-level region, wherein the interpolated gray-level region processing unit is configured to generate the third portion by interpolating between the first portion and the second portion, wherein the first output-data, the second output-data and the third output-data are continuously connected along a gray level axis of the measured input luminance curve and are generated based on the luminance values of respective first, second and third portions, and wherein the interpolated gray-level region is between the compensated gray-level region and the uncompensated gray-level region with respect to the gray-level axis.
