Abstract:
1. A flat panel display device comprising: an array substrate including: an opposing substrate having a common electrode being disposed facing the pixel electrode; a display layer held between the array substrate and the opposing substrate; and a control circuit configured to allow moving image data to be written to the pixel electrode during typical display operation and at the time of switching from a typical display to a still image display, assign as write frames at least initial two frames following the completion of the switching in order to allow still image data to be written to the digital memory, and further, to allow still image data latched in the digital memory to be written to the pixel electrode during still image display operation, wherein the device is further constructed such that at least one of the rise times of a memory control signal supplied to the switch circuit and a common signal supplied to the common electrode is made longer than a vertical blanking period immediately following the completion of the typical display.
