Abstract: A moon phase display includes a frame and a plurality of display elements supported by the frame and rotatable relative to the frame. The plurality of display elements further includes a first side face on which an illuminated moon portion is depicted and a second side face. A first rotational position in which the first side face is arranged along a display plane wherein the first side faces together arranged on along the display plane represent a full moon. A second rotational position in which the second side face is arranged along the display plane. A drive rotates each of the plurality of display elements independently. A controller actuates the drive so that each one of the plurality of display elements is rotated into the second rotational position until all of the plurality of display elements are located in the second rotational position.

Abstract: A display device for displaying a selection of permanently specified display elements with a front panel that has a plurality of windows that form a number of permanently specified display elements, an electrophoretic electronic paper that is arranged behind the front panel so that a partial surface of the electronic paper is assigned to each of the windows, and an electronic control with which a degree of reflection of the electronic paper can be set for each of the partial surfaces.

Abstract: The invention concerns a timepiece that has a single hand, which is movable into a plurality of hand positions. The timepiece has a clockwork for mechanically moving the hand so that the hand is located in a hand position which corresponds to a current time of day and an actuating element connected to the clockwork. The clockwork is designed to change, upon actuation of the actuating element, from a first operating state into a second operating state and to move the hand so that the hand position in the first operating state displays minute information and in the second operating state displays hour information.

Abstract: A device for displaying a text message, comprising a display (10) having a plurality of characters, each of said characters being arranged at a fixed position, not overlapping with any other of said characters, and being adapted to be switched on and off, and a controller being connected to said plurality of characters and being adapted to switch on and off selected characters so that at a given time, a selected sub-group of said characters is switched on, the selected sub-group displaying a text message.
