Patent Images
1. An electronic rear screen projection display device comprising:
- a light source producing an image, a screen having a rear surface for receiving light from the light source, and a front surface adapted to be viewed, and at least one mirror disposed in a light path between the light source and the screen so that it reflects the image produced by the light source, the mirror comprising a multilayered, non-metallic, polymeric optical film with a reflectivity of at least 96% from 400 nm to 700 nm.

2. A method of enhancing the optical quality of an image to be viewed in a projection display device comprising the steps of:
-
producing an image from a light source, providing a screen having a rear surface for receiving light from the light source, and a front surface for viewing, placing at least one mirror in a light path between the light source and the screen, the mirror comprising a multilayered optical film, and reflecting at least 96% of light in the wavelength range from 400 nm to 700 nm in the mirror, and receiving the reflected light on the back surface of the screen.
