Abstract
Disclosed are a display screen of an image display system capable of displaying a 3D (three-dimensional) image and providing an image with a high contrast ratio in a bright room and a method for manufacturing the same. The display screen includes: a Fresnel lens layer; a reflective layer formed the light-exit surface of the Fresnel lens layer to reflect image light; and a protection layer formed on the light-incident surface of the Fresnel lens layer, wherein one surface of the protection layer may have an embossed pattern.
Claims22
A display screen comprising:
- a Fresnel lens layer;
- a reflective layer formed on a light-exit surface of the Fresnel lens layer to reflect image light;
- a primer formed on a light-incident surface of the Fresnel lens layer;
- a protection layer formed on the primer;
- a light diffusion layer formed on the protection layer;
- and
- a surface reflection reducing layer formed on the light diffusion layer,
- wherein one surface of the protection layer has an embossed pattern, and the primer is formed between the light-incident surface of the Fresnel lens layer and the protection layer to bond the protection layer and the Fresnel lens layer, and
- wherein the primer has a predetermined thickness less than a thickness of the protection layer and is configured to reduce a phase difference between the Fresnel lens layer and the protection layer.
A method for manufacturing a display screen, the method comprising:
- forming a reflective layer on a light-exiting surface of a Fresnel lens layer to reflect image light incident from a projector;
- forming a primer on a light-incident surface of the Fresnel lens layer;
- forming a protection layer on the primer;
- forming an embossed pattern on one surface of the protection layer;
- forming a light diffusion layer on the protection layer;
- and
- forming a surface reflection reducing layer on the light diffusion layer, wherein the primer is formed between the light-incident surface of the Fresnel lens layer and the protection layer to bond the protection layer and the Fresnel lens layer, and
- wherein the primer has a predetermined thickness less than a thickness of the protection layer and is configured to reduce a phase difference between the Fresnel lens layer and the protection layer.
