The invention relates to a protective device for a display unit (DU) of an electric device (CD) having a cover element (AE) which can be rolled up. In a rolled up state, said cover element at least partially exposes the display unit (DU) and in a first unrolled state at least partially covers the display unit (DU). The protective device also comprises a rolling-up device for rolling up and unrolling the cover element (AE) on top of the display unit (DU). The invention also relates to a protective device for a display unit (DU) of an electric device (CD) having a flip-type cover element (AE) which at least partially exposes the display unit (DU) in the flipped up state and at least partially covers the display unit (DU) in the flipped down state. The inventive protective device is characterized in that a keyboard is integrated into the cover element and can be operated in the flipped down state. |
