ABSTRACT:
In order to display the information useful for a user on a display screen at all times while saving the power for displaying, a CPU re-edits an image data stored in a VRAM into a 1/4 screen and activates a display driver for the 1/4 screen if the display of one frame of image has been completed. The CPU sets the values of a clock required to scan one line and one frame to a first register and a second register respectively. A load timing controller and a frame signal controller determine the size of screen displayed by the values set in the registers. Thus, there is provided a device on which appropriately edited data is displayed in a small screen.
