Display control apparatus and method with initialization capability

A display control method for displaying images on a display panel in accordance with information stored in memory, comprising the steps of:

• storing display data in a memory;
• displaying an image on the display panel in accordance with the stored display data;
• detecting a power-off signal;
• rewriting the display data stored in the memory by a predetermined data when the power-off signal is detected;
• initializing the display panel by reading the predetermined data from the memory and displaying a refreshed image on the display panel corresponding to the predetermined data;
• and
• disconnecting the power.

An information processing system comprising:

• display means, including a display panel, for displaying information;
• storing means having memories for storing information to be displayed on said display panel;
• display control means for achieving an image on said display means in accordance with the information stored in said storing means;
• power means for supplying power to said information processing system;
• switch means for switching said power means on and off;
• detecting means for detecting a power-off signal;
• and
• rewriting means for rewriting the information stored in said storing means by a predetermined data when said detecting means detects a power-off signal, wherein the display panel is initialized by reading the predetermined data from said storing means and displaying a refreshed image on the display panel corresponding to the predetermined data thereby erasing the image on said display panel and displaying the refreshed image.

A display control apparatus comprising:

• storing means having memories for storing display data to be displayed on a display panel;
• display control means for achieving an image on the display panel in accordance with the display data stored in said storing means;
• detecting means for detecting a signal which initiates achieving a predetermined refreshed image to be displayed on the display panel by said display control means;
• and
• rewriting means for rewriting the display data stored in said storing means by a predetermined data when said detecting means detects the signal which initiates achieving the predetermined refreshed image on the display panel, wherein the display panel is initialized with the predetermined refreshed image when said display control means reads the predetermined data from said storing means and achieves the predetermined refreshed image corresponding to the predetermined data by displaying the predetermined refreshed image on the display panel thereby erasing the image on the display panel and displaying the refreshed image.
