Abstract
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.
