Abstract
A display system includes a projection screen and a projector. The projection screen includes a retarder plate between a polarizer and a transparent screen. The projector projects an image through the polarizer and the retarder plate onto the transparent screen. The image is visible from a first side of the transparent screen but invisible from a second side of the transparent screen because any light passing twice through the retarder plate is blocked by the polarizer.
Claims13
A one-way transparent display system, comprising:
- a transparent display that actively emits a polarized image from first and second sides of the transparent display;
- and
- a polarizer on the first side of the transparent display that substantially blocks any light from the polarized image that reaches the polarizer so the polarized image is substantially visible from only the second side of the transparent display;
- wherein any person on the side of the polarizer sees through the display system without seeing the polarized image and any other person on the side of the transparent display sees the polarized image.
A one-way transparent display system, comprising:
- a transparent organic light-emitting diode display that actively emits a polarized image from first and second sides of the transparent organic light-emitting diode display;
- and
- a polarizer on the first side of the transparent organic light-emitting diode display, the polarizer substantially blocks any light from the polarized image that reaches the polarizer so the polarized image is substantially visible only from the second side of the transparent organic light-emitting diode display;
- wherein any person on the side of the polarizer sees through the display system without seeing the polarized image and any other person on the side of the transparent organic light-emitting diode display sees the polarized image.
A method for providing a one-way transparent display system, comprising:
- actively emitting a polarized image from first and second sides of a transparent display;
- and
- from the first side of the transparent display, blocking any light from the polarized image with a polarizer so the polarized image is substantially visible from only the second side of the transparent display;
- wherein any person on the side of the polarizer sees through the display system without seeing the polarized image and any other person on the side of the transparent display sees the polarized image.
A method for providing a one-way transparent display system, comprising:
- actively emitting a polarized image from first and second sides of a transparent organic light emitting diode display;
- and
- from the first side of the transparent organic light emitting diode display, blocking any light from the polarized image with a polarizer so the polarized image is substantially visible from only the second side of the transparent organic light emitting diode display;
- wherein any person on the side of the polarizer sees through the display system without seeing the polarized image and any other person on the side of the transparent organic light-emitting diode display sees the polarized image.
