| 20100053762 | Intensity-Based One-Way Visible Display System - A one-way display system includes a partially reflective screen with a first image, and a partially absorptive screen with a second image that is an inverse of the first image. The two screens can be stacked on top of each other or separated by a small distance. A portion of ambient light on a first side of the display system passes through the partially reflective screen and exits as intermediate light. A portion of the intermediate light passes through the partially absorptive screen and exits as transmitted light to a second side of the display system. The transmitted light is spatially and chromatically uniform like the ambient light. This allows observers on the second side to see objects on the first side without the first image, and observers on the first side to see the first image. | 03-04-2010 |
| 20090147185 | Reflective One-Way Screen with Chromatic and Transparent Regions - A one-way display system has a display layer with opaque active pixels and transparent inactive pixels interspersed with the active pixels. Each active pixel has a chromatic side and an opaque side. The active pixels is able to form an image visible from a first side of the display layer but not from a second side of the display layer, and the inactive pixels allows objects on the first side of the display layer to be seen from the second side of the display layer. | 06-11-2009 |
| 20090027630 | One-Way Display Using Color Filter - A one-way display system includes a transparent screen and a transparent color filter. An image is emitted by the screen or projected onto the screen. The image is formed from a combination of colored lights. Instead of spanning all the wavelengths of each color, each light only spans a narrow band of the color. The color filter removes the narrow band so the image is only visible from one side of the screen. As the color filter removes only the narrow band, one can still look out and see objects on the other side of the screen minus the colors of the narrow band. | 01-29-2009 |
