Projection Graphics Using One-Way Vision Screens

Abstract

A method and apparatus for one-way graphics using a projector that projects an image onto a screen, wherein the screen is comprised of a non-transparent material, and the screen contains voids sufficient in size and distribution to allow clarity of vision when viewed through from the side opposite the projection, and wherein the area of the screen substantially reflects the projected image so that on observer viewing the screen from the projection side of the screen sees the image that is projected onto the screen. The apparatus and method may further comprise a light-absorbing layer on the back of the screen, wherein the voids in the screen extend through the light-absorbing layer. The one-way screen may include additional transparent layers for mounting and adhesion.

Description

[0001]This invention relates to materials and methods for one-way graphics involving projected images. This application claims benefit under 35 U.S.C. §120 of the filing date for application No. 61 / 656,681 filed Jun. 7, 2012.BACKGROUND OF THE INVENTION[0002]One-way graphic materials are materials that have an image on one side, yet permit vision through the material from the other side. Optical properties are manipulated such that the material appears opaque from the image side, but appears substantially transparent when viewed from the non-image side. Generally, one-way graphic materials are light permeable, with one relatively dark side and one relatively light side. Images are typically placed on the light side of the one-way material. People viewing from that side will see the image. People viewing the material from the back side of the material do not see the image, but instead see the environment on the far side of the one-way graphic. Other forms of one-way graphics use trans...

AI Technical Summary

Benefits of technology

Enables easy introduction of new images without replacing the screen and allows for the display of moving images, enhancing the visual appeal and engagement in commercial and retail settings by utilizing projection technology, creating a dynamic presence that can attract customers.

Problems solved by technology

One-way graphics typically use expensive perforated substrates, upon which an image is printed using digital printers or silk screening.

Furthermore, existing technology for one-way graphic displays is entirely static, and does not allow for any movement of the image on the one-way graphic display.

Thus, the prior art fails to take advantage of many of the advantages associated with motion pictures, television, and other video arts based on projection of images, where a single projection panel can be used to display many different types of images, and can portray motion.

Similarly, although perforated screens are known in the visual arts, these generally involve screens with very small and or infrequent perforations, such that the screens are non-transparent under any circumstances.

They are not suitable for use in window displays or any other types of display where the user desires the screen to be essentially transparent when the user is viewing outward from behind the screen.
