Abstract
An image display device may have a display portion, a signal-processing portion, a power supply portion that supplies power to the display portion and the signal-processing portion, a user interface portion, and a control portion that controls the display portion, the signal-processing portion, and the power supply portion. An operation mode may include a waiting mode in which power supply to the display portion and the signal-processing portion stops, an image-display-waiting mode in which power is supplied to the signal-processing portion but power supply to the display portion stops, and an image display mode in which power is supplied to the display portion and the signal-processing portion. The control portion may switch the operation mode, based on the operation signal, from the waiting mode or the image-display-waiting mode to the image display mode or from the image display mode to the image-display-waiting mode.
