Abstract
A device includes a first display, a second display, a battery, a control processor, and a second processor. The second display consumes less power than the first display. The control processor changes a display mode of the device between a first display mode and a second display mode. In the first display mode the first display displays information, and in the second display mode the second display displays information. The control processor switches from the first display mode to the second display mode to give the battery a longer life. The control processor is operated by an “Operating System” (OS), and the second processor is operated by a “Basic Input Output System” (BIOS).
Claims20
A device, comprising:
- a first display;
- a second display which, in operation, consumes less power than the first display;
- a battery;
- a control processor which, in operation, changes a display mode of the device between a first display mode and a second display mode, wherein in the first display mode the first display displays information, and in the second display mode the second display displays information;
- and
- a second processor;
- wherein the control processor switches from the first display mode to the second display mode to give the battery a longer life, and
- wherein the control processor is operated by an “Operating System” (OS), and the second processor is operated by a “Basic Input Output System” (BIOS).
A device, comprising:
- a first display;
- a second display that has a lower resolution than a resolution of the first display;
- a first processor;
- a second processor that has lower performance than a performance of the first processor,
- wherein the first processor is operated by an “Operating System” (OS), and the second processor is operated by a “Basic Input Output System” (BIOS),
- wherein the first processor or the second processor controls a light-emitting status of a light source at least in a state in which a first image is being displayed on the first display,
- wherein the second processor controls the light-emitting status of the light source in a state in which a second image is being displayed only on the second display,
- wherein the second display is located on an upper side of the first display closer to a viewer than the first display,
- wherein the first processor sends data for changing information displayed on the first display, and
- wherein the second processor sends data for changing information displayed on the second display.
