Abstract
Disclosed is a processing on a host side and a panel side, thus optimizing a work load of the whole of a system including a graphics chip. Provided is an image display system which comprises a host side for executing an application and a panel side connected to the host side, and displaying an image on the panel side, the host side transferring undeveloped image data to the panel side when an image display is requested of the panel side having a panel memory for developing the image, the panel side developing the image in the panel memory based on the image data transferred from the host side and displaying the image developed in the panel memory on the panel.
