ABSTRACT:
A display device includes a display panel, a data line driving circuit, a timing control unit and a parameter output unit. The data line driving circuit drives data lines on the display panel. The timing control unit outputs an input gradation signal based on an image signal to the data line driving circuit at a predetermined timing. The parameter output unit outputs a conversion parameter for executing gamma correction corresponding to characteristics between a driving voltage and a luminance of the display panel. The data line driving circuit includes: a correction circuit which converts the input gradation signal to an output gradation signal based on the conversion parameter and outputs the converted signal, and a D/A conversion circuit which converts the output gradation signal to a data line driving signal of an analog signal and drive the data lines.
