Abstract
When the display rate of a plasma display reaches a display rate exceeding the rated maximum electric power of the plasma display, the display mode of the plasma display is switched from a high brightness display mode to a normal brightness display mode. An item for selecting whether or not a battery recharge operation is enabled is provided to a setup menu screen. A user arbitrarily selects a charge mode (a battery charge operation is enabled in the normal brightness display mode) or a non-charge mode (the battery charge operation is disabled in the high brightness display mode). When the charge mode is selected, an electric power value obtained by subtracting electric power necessary for recharging the battery from the rated maximum electric power of the plasma display is set as a reference value, and when the display rate requires electric power exceeding the reference value, the display mode is switched from the high brightness display mode to the normal brightness display mode.
