Abstract
A luminance compensation system of a display device and a luminance compensation method thereof are disclosed. The luminance compensation system includes a display panel including a plurality of pixels, a TFT and an OLED, a luminance meter configured to measure luminance at a plurality of positions and obtain a plurality of measure values for each of the plurality of positions in a state where modeling voltage patterns are applied to the plurality of positions, a first modeling unit configured to model the plurality of measure values to derive a first luminance characteristic approximate equation, and a second modeling unit configured to obtain a luminance error between the measure value and a luminance value in accordance with the first luminance characteristic approximate equation, after calculating an offset correction parameter, and apply the offset correction parameter to the first luminance characteristic approximate equation to derive a second luminance characteristic approximate equation.
