Abstract
The invention relates to a display device for displaying visual information, comprising: at least one image-forming element; at least one light source for generating a light beam, which in cooperation with the image-forming element produces an illuminated image; optical means for processing the light beam and/or illuminated image; and a projection surface for receiving the illuminated image, wherein the image-forming element is flat and the projection surface forms at least a part of a cylinder wall.
Claims17
A display device for displaying visual information, comprising:
- at least one image-forming element;
- at least one light source for generating a light beam, which in cooperation with the image-forming element produces an illuminated image;
- optical means for processing the illuminated image;
- and
- a projection surface for receiving the illuminated image,
- wherein the image-forming element is flat and the projection surface forms a cylinder wall, wherein the optical means project a cylindrical illuminated image on the projection surface, and wherein the projection surface is manufactured from a transparent material such that an image projected onto the inside of the cylinder wall is visible on the outside of the cylinder wall, and
- wherein the image-forming element is coupled to a computer for control thereof.
A display device for displaying visual information, comprising:
- at least one image-forming element;
- at least one light source for generating a light beam, which in cooperation with the image-forming element produces an illuminated image;
- optical means for processing the illuminated image;
- and
- a projection surface for receiving the illuminated image,
- wherein the image-forming element is flat and the projection surface forms a cylinder wall, wherein the optical means project a cylindrical illuminated image on the projection surface, wherein the optical means comprise a part of a reflecting sphere, and wherein two mutually facing parts of reflecting spheres are disposed in a projection surface in the form of a cylinder shell and have central openings arranged therein for passage of the light cast by two projectors.
A display device for displaying visual information, comprising:
- at least one image-forming element;
- at least one light source for generating a light beam, which in cooperation with the image-forming element produces an illuminated image,
- optical means for processing the illuminated image;
- and
- a projection surface for receiving the illuminated image,
- wherein the image-forming element is flat and the projection surface forms a cylinder wall, wherein the optical means project a cylindrical illuminated image on the projection surface, and wherein the projection surface is formed by a cylinder shell-shaped Fresnel lens.
