摘要： An electro-optical apparatus is provided which corrects a voltage applied to a pixel with high accuracy. An electro-optical apparatus includes a correction circuit. When, for example, a positive-polarity selection voltage +VS is applied to a scanning line during the second-half period of one horizontal scanning period, the correction circuit detects a spike resulting from voltage switching from a voltage −VD/2 to a voltage +VD/2 on the data lines, determines whether the level of the detected spike is a threshold level or more, and if a determination is made that the level of the detected spike is the threshold level or more, adds a pulse with the same polarity as that of the detected spike to a selection-voltage supply line in the second-half period following the first-half period.

摘要： In order to reduce power consumption in halftone display, each horizontal scanning period for which one of a plurality of scanning lines is selected is divided into first and second half periods. A nonselection voltage for bringing a TFD into a nonconductive state for the first half period and a selection voltage for bringing the TFD into a conductive state for the second half period are supplied as a scanning signal to the scanning line. When an odd scanning line is selected, a right shift modulation method is applied to the pixels located on the relevant scanning line; when an even scanning line is selected, a left shift modulation method is applied to the pixels located on the relevant scanning line. Thus a data signal Xi is supplied to the relevant data line. Since only one voltage switching of the data signal Xi per one horizontal scanning period is required for white or black display, and since only two voltage switchings are required for halftone display, the power consumption required for voltage switching is reduce.
