Abstract:
A display element driving device comprising:a D/A converter for applying a voltage based on a given image signal to an electrode line that is electrically connected to a capacitive display element having one side to which a given voltage is applied, wherein said D/A converter includes: first charge storage means for receiving image digital data corresponding to the image signal and for storing a charge corresponding to a value of the image digital data; second charge storage means for receiving correction digital data for compensating for display characteristics of said display element and for storing a charge corresponding to a value of the correction digital data; first connection means for electrically connecting said first charge storage means to said electrode line and for discharging the charge stored in said first charge storage means to said electrode line at a given timing; and second connection means for electrically connecting said second charge storage means to said electrode line and for discharging the charge stored in said charge storage means to said electrode line at a substantially same timing as the given timing.
