Abstract:
1. A method of driving a display device carrying out frame-reversal drive of a display section which comprises a plurality of pixels each including an active element, the method comprising: setting at least two refresh rates with respect to the plurality of pixels; writing data into pixels in the display section in each frame at a first rate that is a fastest rate among the at least two refresh rates; and writing data with both polarities, when data is intermittently written into pixels in the display section, at a second rate that is lower than the fastest rate among the at least two refresh rates, wherein the display section is divided into at least two areas including a display area and a non-display area, and data is intermittently written into pixels in the non-display area at the second rate, wherein, when data is intermittently written into the non-display area pixels at the second rate, a difference between (i) the number of times of writing into the non-display area pixels with one polarity and (ii) the number of times of writing into the non-display area pixels with the other polarity is set to be not more than a predetermined value, during a period of applying a voltage to the non-display area pixels, wherein on occasion of writing the data into the non-display area pixels at the second rate, a scanning operation timing signal for generating a drive signal for carrying out the frame-reversal drive and a scanning non-operation timing signal for generating no drive signal are set for each frame, wherein the scanning operation timing signal causes polarities of the drive signal to be reversed between a frame and a previous frame to the frame, and the scanning non-operation timing signal causes the polarities of the drive signal to be unchanged between the frame and the previous frame, and wherein an interval between frames of the scanning non-operation timing signal is equal.
