A drive order control circuit 14 generates a drive order control signal LR so as to change periodically, such as every frame time or every line time. Based on the drive order control signal LR, a data signal line drive circuit 3 switches between driving data signal lines S1 to Sm in the left-to-right direction in accordance with the disposition order, and driving them in the right-to-left direction in accordance with the disposition order. A memory control circuit 15 switches the order of reading digital video signals Vd from a frame memory 12 in units of one or more lines in accordance with the drive order control signal LR. By changing the order of driving the data signal lines, it becomes possible to disperse any ghost generated on the display screen in the temporal and/or spatial directions, thereby reducing the visibility of the ghost. Thus, it is possible to prevent any ghost from being generated on the display screen of any display device performing dot-sequential drive, in a simple manner other than a two-fold pulse drive method. |
