Benefits of technology

This patented technology describes an improved way to make displays like lights look better at low-level environments such as homes without glare caused by direct sunshine. These screens have tiny mirrors called prismatic crystals embedded within them. When there're no external light nearer than this screen, it can be seen clearly through these gratings. To prevent reflection towards other people we also coat some materials onto their surfaces to reduce reflections. Overall, this design helps create more comfortable indoor spaces while still displaying high quality images.

Problems solved by technology

Technological Problem: Existing methods such as holograms suffer from imperfections caused by factors like uneven distribution of energy across the entirety of the display screen (the size of each pixel) resulting in blunting effects and decreased resolution. Additionally, existing techniques require high costs and bulbs, making them unsuitable for some uses requiring near darkness imagery.

Embodiment Construction

Those of ordinary skill in the art will realize that the following description of the present invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons.

FIG. 1 illustrates a holographic display system 10 suitable for use as a night light or dim light which is used in darkness or dimly lit environment for safety, security or decoration according to the present invention. In holographic display system 10, a light source 12 for illuminating a hologram 14 for replay of a holographic image previously recorded in the hologram 14 is in close proximity to the hologram 14. Both the light source 12 and the hologram 14 are disposed within a housing 16.

The registration of the light source 12 and hologram 14 within the housing is such that any light from the light source 12 which does not fall upon the hologram 14 remains within the housing. Further, light from the light source 12 which falls upon the surfac

Abstract

A holographic display system provides a holographic image suitable for use as a nightlight in a dimly lit environment wherein the only light in the field of view of the user is essentially the light diffracted into the holographic image being replayed. The holographic display system includes a low watt light source, a hologram recorded with a reference beam matching the beam of the light source employed to replay the hologram, and an enclosing structure for holding the lightsource and hologram in registration wherein the enclosure is configured so that the only light emitted from the display system is emitted from the hologram.
