Patent ID: 7327358

Claim:
A cross-talk correction circuit of an electro-optical apparatus, the electro-optical apparatus including: pixels provided at intersections of a plurality of scanning lines and a plurality of data lines; a scanning-line drive circuit which sequentially selects the scanning lines every one horizontal scanning period and applies a selection voltage to a selected scanning line over a second-half period of the one horizontal scanning period; and a data-line drive circuit which: applies a non-lighting voltage to one data line over a period according to the gradation of a pixel, the period being included in a first-half period in one horizontal scanning period; applies a lighting voltage to the one data line over the rest of the first-half period; applies a lighting voltage to the one data line over a period in the second-half period according to the gradation of the pixel; and applies a non-lighting voltage to the one data line over the rest of the second-half period, the cross-talk correction circuit comprising: a detection circuit which detects a spike resulting from switching from one of the lighting voltage and the non-lighting voltage to the other in a first-half period in one horizontal scanning period; a determination circuit which determines whether the level of a detected spike is at least a threshold level; and an addition circuit which adds a pulse with the same polarity as that of the detected spike to the selection voltage in a second-half period following the first-half period if a determination is made by the determination circuit that the level of the detected spike is at least the threshold level.
