Abstract:
1. A display unit connected to a computer main unit to display images, comprising: a power supply section which supplies power to the display unit; a display section which performs image display on the basis of an image signal supplied from the computer main unit; a power supply control section which controls, on the basis of a sync signal contained in the image signal, switching between an energization mode in which the power supply section is in an on state and a power save mode in which the power supply section is in an off state; and a power save termination determination circuit which is driven by auxiliary power for peripheral devices supplied from the computer main unit, which makes a determination on the basis of the sync signal as to whether or not a return from the power save mode to the energization mode should be made, and returns at least the power save control section to the on state in the case of determining that a return to the energization mode should be made, and which has a power consumption lower than that of the power save control section.
