Patent ID: 6940484

Claim:
A method for driving a display device driving a pixel provided corresponding to each of intersections between a plurality of scanning lines and a plurality of data lines, wherein: one scanning line in said plurality of scanning lines is selected every one horizontal scanning time period, and a selection voltage is applied to the selected scanning line in one of time periods into which the one horizontal scanning time period is divided; the polarity of said selection voltage is reversed at least every two or more horizontal scanning time periods on the basis of an intermediate value of an ON voltage and an OFF voltage applied to said data lines; and when a pixel belonging to a specific data line in said plurality of data lines is put into a display state, and pixels belonging to other data lines are put into a non-display state, an ON voltage is applied to said specific data line in one horizontal scanning time period, in which one scanning line in said plurality of scanning lines is selected and a selection voltage is applied to the selected scanning line according to the contents to be displayed by a pixel corresponding to an intersection between the selected scanning line and the specific data line, and an ON voltage and an OFF voltage are applied to said specific data line for substantially the same period over one horizontal scanning time period in which the selected scanning line is selected, while an OFF voltage is supplied to data lines other than said specific data line according to the polarity of the selection voltage applied to the selected scanning line, and by reversing the polarity every polarity reversal period of said selection voltage; when a scanning line is selected, a selection voltage is applied to the selected scanning line in the second half time period of one of time periods, into which one horizontal scanning time period is divided; when the next one scanning line is selected, a selection voltage is applied to the selected scanning line in the first half time period of one of time periods, into which one horizontal scanning time period is divided; and the selection voltage is alternately applied in one time period and in the other time period every one horizontal scanning time period.
