Title: METHOD FOR DRIVING DISPLAY, DRIVING CIRCUIT THEREFOR, DISPLAY, AND ELECTRONIC APPARATUS
Abstract:
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 reduced.
