Abstract
A thin film reflective screen includes a surface layer, a transmission layer, a diffusion layer and reflection layers, which are formed in a single screen, which has functions such as an image forming on a surface, scattering, transmission, diffusion, and reflection, which are duplicated by re-reflecting light such that an image signal of pixel unit of an electronic image projected from a DLP projector or an LCD projector is enlarged to increase definition and brightness of the image. A dark color layer is formed on the surface of the screen such that contrast of the image is increased during the diffusion and the reflection, and as a result, resolution of the image is increased by two to nine times.
Claims9
A high definition thin film reflective screen comprising:
- a surface layer on which an image is formed;
- a diffusion layer and a transmission layer formed as one layer at the rear side of the surface layer;
- and
- reflection layers formed at the rear side of the diffusion layer;
- wherein
- transmittance, diffusion, and reflection of light which is incident upon the screen from a projector occur such that the area of a unit pixel which is produced upon the screen is doubled.
A high definition thin film reflective screen comprising:
- a dark color layer;
- a surface layer defined at the rear side of the dark color layer to form an image;
- a diffusion layer and a transmission layer formed as one layer at the rear side of the surface layer;
- and
- reflection layers formed at the rear side of the diffusion layer;
- wherein
- transmittance, diffusion, and reflection of light which is incident upon the screen from a projector occur such that the area of a unit pixel which is produced upon the screen is doubled.
A high definition thin film reflective screen comprising:
- a surface layer on which an image is formed;
- a transmission layer through which light is transmitted and diffused;
- and
- a reflection layer through which light is diffused and re-reflected;
- wherein image light that is transmitted and diffused by the transmission layer is subsequently reflected and diffused by the reflecting layers so that the light is caused to be diffused and transmitted through the transmission layer again and combined with the image formed on the surface layer such that the signal of a unit pixel is enlarged more than twice.
