Abstract

A current driver circuit includes a DA conversion part for generating a display current whose magnitude corresponds to a value of a displayed data, a timing control part for generating a write controlling signal, and a plurality of electric current latching parts, each of which generates a driving current. Each of the electric current latching parts having a capacitor generates a display current whose magnitude corresponds to a magnitude of a voltage to which the capacitor is charged. Each of the elective current latching parts performs a reset operation that once discharges the capacitor in response to a reset signal generated by the timing control part. The current driver circuit can generate the driving current with high accuracy and improve the speed of response to the display device.
