Abstract:
A gray scale correction method for a display device includes a step of setting a target value including a target luminance and a target chromaticity of a color display pixel (S22), a step of measuring tristimulus values of each of a plurality of reference colors and each of a plurality of comparative colors in accordance with a prescribed gamma characteristic (S24), a step of finding a reference value and a comparative value from the measured tristimulus values (S26), and a step of correcting a gray scale based on the target value, the reference value and the comparative value (S28).
