DISPLAY PANEL DRIVING DEVICE AND DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a driving device which maximally brings out representing capabilities of respective colors of RGB of an organic EL panel while securing white balance.

SOLUTION: The driving device which supplies an analog driving signal to a display panel to drive the display panel includes; a digital video signal supply part for supplying a digital video signal; a hue signal generation part for generating a hue signal representing hue of the digital video signal; a saturation signal generation part for generating a saturation signal representing saturation of the digital video signal; a gain control signal generation part for generating a gain control signal controlling a gain of the analog driving signal, on the basis of the hue signal and the saturation signal; and an analog driving signal generation part for generating the analog driving signal from the digital video signal on the basis of the gain control signal.
