Abstract
For the purpose of simultaneous presentation of an information on a display array (6) a display means has an image movement device (12,13), with the aid of which the image of the display array can be aimed in different directions, preferably along a circle. In addition, an optical bundling system (15) is provided which aims the image in one certain direction only, depending on the momentary position of the image movement device (12,13). Against the viewer a transparent screen (18;58) is provided.
Claims11
A display means, for directing an image along an angularly movable axis;
- comprising
- a display surface arranged in a plane for displaying an image;
- light source means for emitting light along an optical path comprising the optical axis for illuminating the display surface;
- image movement means for moving the display surface so as to swing the angularly movable axis about a rotational axis;
- and
- aperture means for exposing adjacent portions of the display surface along lines of sight which, for each position of the movable axis, correspond with respective adjacent portions;
- the aperture means comprising optical bundling means which simultaneously transmit light from a plurality of adjacent portions of the displayed image along the movable axis and, at the same time, prevent light from being transmitted from said adjacent portions of the displayed image at an angle to said movable axis, while light reflecting means are provided for deviating the optical path of light emitted by the light source means, the display device further comprising a screen being transparent for transmitting the image which surrounds the moving image.
