Patent ID: 7079123

Claim:
A driving apparatus for a matrix panel in which a modulation element is arranged in each of intersections of a matrix composed of a plurality of row wirings and a plurality of column wirings, comprising: a row driver circuit adapted to supply a row selection signal to the row wiring selected among the plurality of row wirings; a correction circuit that corrects a voltage of the row selection signal so as to suppress a voltage variation of the row selection signal, which is caused due to at least a resistance of an output stage of the row driver circuit and a current caused to flow into the resistance; and a column driver circuit adapted to supply to the plurality of column wirings a modulation signal having a pulse width and a voltage amplitude with at least the pulse width modulated according to gradation information, the column driver circuit generating the modulation signals different in start reference time in one horizontal scanning period and/or obtained by using pulse width modulation and voltage amplitude modulation in combination.
