Abstract:
A method of driving a display device so as to display a gray-scale image by driving pixels disposed at locations corresponding to respective intersections of a plurality of scanning lines extending along rows and a plurality of data lines extending along columns, said method comprising:sequentially selecting said plurality of scanning lines one by one every horizontal scanning period; applying a selection voltage to a selected scanning line during one of two half periods that said horizontal scanning period has been divided into; and applying a voltage to a pixel such that: in the case in which, of said plurality of scanning lines, a scanning line in either an odd-numbered or an even-numbered row is selected, a turn-on or a turn-off voltage is applied to a pixel at a location corresponding to an intersection of said scanning line and a data line belonging to a first group such that in one of said two half periods of each horizontal scanning period the turn-on voltage is applied via said data line to said pixel during a period from the start of one of the two half periods of the horizontal scanning period until a time corresponding to a gray level has elapsed, and the turn-off voltage is applied to said pixel during a remaining period of said one of the two half periods, while, in the case in which, of said plurality of scanning lines, a scanning line in the other one of odd-numbered and even-numbered rows is selected, the turn-on or the turn-off voltage is applied to the pixel at the location corresponding to the intersection of said scanning line and the data line belonging to the first group such that the turn-on voltage is applied via said data line to said pixel during a period from a point of time earlier than the end of said one of the half periods of the horizontal scanning period by an amount of time corresponding to a gray level until the end of said one of the two half periods, and the turn-off voltage is applied to said pixel during remaining period of said one of the two half periods, and in either of these cases, in the other of said two half periods of said horizontal scanning period, the turn-on voltage is applied during a period equal to the period in which the turn-off voltage is applied in said one of the two half periods, while the turn-off voltage is applied during a period equal to the period in which the turn-on voltage is applied in said one of the two half periods.
