Definitions

  • the present invention relates to a device for visualizing images, information and the like.
  • Different types of screen are already known for displaying images, information or the like, such as for instance LCD screens, plasma screens, TFT screens, LED screens, OLED screens, LCD projectors, DLP projectors and the like.
  • a drawback of the known screens is that they display a two- dimensional image and that a spatial dimension is consequently lacking in the image .
  • the present invention has for its object to provide a solution to the above stated drawback and other drawbacks in that it provides a device for visualizing images, information or the like, wherein the device is provided with a housing, an image-generating element which comprises a light-emitting surface, and an at least partly reflecting mirror with a front side, wherein the light-emitting surface is situated on the front side of said mirror and is disposed relative to the mirror such that the light reflected by the mirror forms a virtual image which is situated behind the mirror.
  • the inner wall of the housing (2) is at least partially light-absorbing.
  • the whole inner wall of the housing is light-absorbing.
  • a part of the inner wall of the housing is light-reflecting.
  • the side walls (6) of the housing (2) are light-absorbing.
  • the upper wall (5) and side walls (6) of the housing (2) are light-absorbing.
  • one or more walls, or layers arranged on these walls, are light-absorbing can mean that more than 50%, or more than 60%, or more than 70%, or more than 80%, or more than 90%, or more than 95%, or more than 99% of the light incident on the wall or layer is absorbed. The better the light absorption, the less undesirable interference by this scattered light there is in the display mechanism.
  • the upper wall (5) and side walls (6) of the housing (2) are provided with a light-absorbing layer .
  • the upper wall of the housing is at least partially light-reflecting.
  • the upper wall can be wholly light-reflecting. It can for instance be provided with a mirror surface or mirror. In such embodiments the image also becomes visible from the rear (i.e. to a viewer looking into the device from the rear) .
  • An advantage of such embodiments is that the device can fulfill the same function on two sides and that multiple viewers can thus view the images simultaneously.
  • Some or all parts of the inner wall which are light- absorbing in determined embodiments of the present invention can be covered for this purpose with a light-absorbing layer .
  • Some or all parts of the inner wall which are light- reflecting in determined embodiments of the present invention can be covered for this purpose with a light- reflecting layer.
  • one or more walls, or layers arranged on these walls, are reflective can mean that more than 50%, or more than 60%, or more than 70%, or more than 80%, or more than 90%, or more than 95%, or more than 99% of the light incident on the wall or layer is reflected.
  • An advantage is that the image seen by a viewer has a depth dimension .
  • Another advantage is that the device is easy to manufacture.
  • a further advantage is that the viewed image is projected onto the partly transparent mirror, so that the viewer located on the front side of the mirror can likewise see, through the viewed image, what is situated behind the mirror .
  • Another advantage is that it is possible to obtain an image which is apparently free-standing in space, wherein the viewer gains the impression that the projected image of an object is for instance floating in space, thereby achieving a special effect which will draw the attention of passers- by, whereby it can be used for all kinds of applications, such as for advertising messages, safety signs or signals, special effects and the like.

  • a housing 2 which is embodied in the shown embodiment as a hollow cube 3 with a bottom 4 and an upper wall 5, which are mutually connected by two upright side walls 6, and the front side 7 and rear side 8 of which are at least partly open so that the view through hollow cube 3 is unobstructed for a viewer.
  • front side 7 and rear side 8 are closed by a wall transparent to visible light, this so that a viewer can still see through hollow cube 3.
  • These optionally present walls on the front and/or rear side are preferably made non-mirrored or anti-reflective so that a viewer would not see him/herself or other external objects on the outside when looking into the cube (or device) .
  • These walls further provide protection against dust and fingerprints on the mirror, which could blur the image and could thus have an adverse effect on image quality. They are preferably also made non-mirrored so that a double projection image would then not occur due to reflections on the surface of the walls directed toward the interior of the cube .
  • housing 2 is embodied as a hollow cuboid or in other suitable form.
  • Housing 2 is provided with an image-generating element 9 which comprises a surface which emits light, which surface is preferably embodied in the form of a screen 10 situated on the bottom 4 of housing 2.
  • Screen 10 is preferably concealed from a viewer located on the front side 7 of device 1, for instance by means of an upright wall 11 which is arranged in front of screen 10 and which covers a part of the open front side 7 of housing 2, and the upper edge 12 of which in the shown example is folded inward at an angle .
  • the inner side of opaque wall 11 is 1ight-absorbing .

  • Device 1 is further provided with an at least partially transparent mirror 15, which is understood to mean that mirror 15 allows through a part of the light, reflects a part and absorbs or diffuses preferably the smallest possible fraction.
  • the mirror can comprise a sheet of glass or consist of a sheet of glass.
  • mirror 15 comprises a sheet of plastic or can consist of a sheet of plastic.
  • Plastic sheets can be light and strong, which is safer and reduces transport costs. They can further span large areas.
  • the plastic sheets are moreover easier to process, for instance for the purpose of rounding off corners of the sheet or mirror. This latter can for instance be provided with rounded corners when the four main surfaces defining the cube (side walls, top and bottom wall) are connected to each other by means of rounded corners (in other words, when a cube is considered with rounded corners) .
  • Plastic sheets of small thickness of for instance about 2 or about 3 mm, preferably a thickness less than 4 or less than 3 mm
  • a ghost effect double edge effect
  • This effect can be a result of reflections on both front and rear surfaces of the mirror or sheet 15.
