Abstract:
1. An apparatus for driving an electro-optical device comprising: a plurality of scanning lines; a plurality of data lines that intersect the plurality of scanning lines; the plurality of data lines including a plurality of groups of data lines; each of the plurality of groups of data lines including a predetermined number of data lines of the plurality of data lines; a plurality of pixels that are disposed at position corresponding to intersections between the plurality of scanning lines and the plurality of data lines; a driving circuit that output a first image signal and a second image signal to at least one of the plurality of data lines; and a pre-charge circuit that output a first pre-charge signal and a second pre-charge signal to at least the one of the plurality of data lines, the first image signal which having a positive polarity with respect to a predetermined potential, the second image signal which having a negative polarity with respect to the predetermined potential, the first pre-charge signal having a first potential which has any one of the positive polarity and the negative polarity, the first pre-charge signal being outputted before the first image signal being supplied to at least the one of the plurality of data lines, and the second pre-charge signal having a second potential which has same polarity with the first pre-charge signal with respect to the predetermined potential, the second pre-charge signal being outputted before the second image signal being supplied to at least the one of the plurality of data lines, an amplitude of the first potential being lower than an amplitude of the second potential when the first and second potentials have the same polarity with the second image signal, the amplitude of the second potential being lower than the amplitude of the first potential when the first and second potentials have same polarity with the first image signal.
