Abstract
A graphic display device for displaying image data provided from a memory includes a transfer memory unit for storing the image data transferred from the memory, a display memory unit for storing the image data transferred from the transfer memory unit, and a display unit for displaying the image data supplied from an image source, the image source being the display memory unit in a first operation mode of the graphic display device. The graphic display device further includes a switching unit for selecting the image source from the display memory unit or the transfer memory unit, so that the display unit can display the image data stored in the transfer memory unit in a second operation mode of the graphic display device.
