摘要

The electrically operated display device (10) has an electrically operated display element (11), a movable, light reflecting shielding element (12) and a detector unit (13) for determining the power supply condition of the display device. A control unit (14) is designed in such a way to guide the shielding element before the display element depending on the power supply condition of the display device. The display element is a display screen, particularly a liquid crystal display. An independent claim is included for a method for protecting an electrically operated display element of a display element from overheating.
