ABSTRACT:
A display control apparatus and method initializes the display when the power is switched off. The display control apparatus includes a storing unit which corresponds to a display panel and stores display data, a display control unit for achieving an image on the display panel in accordance with the data stored in the storing unit, a detecting unit for detecting disconnection of a power source, and an initializing unit for initializing the storing unit when the detecting unit has determined that the power source is disconnected. The display control method performs display by using information stored in a memory corresponding to the display panel. The method is carried out by detecting a request for power disconnection, writing initialization data into the memory, achieving an image on the display panel by using the initialization data written in the memory, and disconnecting the power.
