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.
Claims20
A display screen comprising:
- 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 has a pattern.
A method for manufacturing a display screen, the method comprising the steps of:
- forming a reflective layer on the light-exiting surface of a Fresnel lens layer to reflect image light incident from a projector;
- forming a protection layer on the light-incident surface of the Fresnel lens layer;
- and
- forming an embossed pattern on one surface of the protection layer.
The method of claim 19, wherein, in the step of forming a pattern, a pattern is formed to reduce the phase difference between the lens layer and the protection layer.
