Filed: 2002-07-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a display device which sufficiently reduces its power consumption without degrading a display quality.  <P>SOLUTION: Each pixel part 8 is provided with a pixel charge storage capacity varying circuit 15, and each data signal line 5_n is provided with a data signal line charge storage capacity varying circuit 18, and pixel charge storage capacities and data signal line charge storage capacities are varied in accordance with a frame frequency. At the time of driving with a high frame frequency, pixel charge storage capacities are reduced because a charge holding period is short and charge holding capabilities are not required. In this case, data is sufficiently supplied from a data signal line driving circuit 17 by reducing the data signal line charge storage capacities though a charge write period is short. At the time of driving with a low frame frequency, pixel charge storage capacities are increased because the charge holding period is relatively long and high charge holding capabilities are required. In this case, data is sufficiently supplied from the data signal line driving circuit 17 regardless of increase of the data signal line charge storage capacities because the charge write period is long.  <P>COPYRIGHT: (C)2004,JPO
