Display device and its gamma correction method

A display device displaying a color image made of a plurality of color components, comprising:

• a plurality of pixels for each of the color components;
• a plurality of DA converters, each of the DA converters outputting a voltage to a predetermined number of the pixels;
• a γ-correction voltage switching circuit correcting the voltages outputted to the pixels independently for each of the color components;
• and
• a switching circuit provided for each set of the predetermined number of the pixels, the switching circuit receiving the voltage corrected by the γ-correction voltage switching circuit and outputted by the corresponding DA converter and supplying the voltage selectively to one of the set of the predetermined number of the pixels depending on the color component of said one pixel at a timing of a time sequence different from timings corresponding to other color components.

A γ-correction method of a display device displaying a color image made of a plurality of color components, comprising:

• receiving display signals corresponding to the color components;
• performing a γ-correction on the display signals independently for each of the color components;
• and
• writing the γ-corrected display signals for each of the color components at a timing of a time sequence for displaying the color image, the timings of the writing being different among the color components.
