Abstract
A screen for a projection display system. The screen has a Fresnel lens for converting incoming light into parallel light and a Lenticular lens disposed on a surface of the Fresnel lens to change a path of the parallel light from the Fresnel lens, providing a three-dimensional image to a user. The Lenticular lens includes plural pixel lenses corresponding to pixels of the screen. Each of the pixel lenses has a central diffusing portion formed on a light-outgoing portion and a peripheral diffusing portion formed on a peripheral portion of the central diffusing portion.

A screen for a projection display system, comprising:
- a Fresnel lens for converting incoming light into parallel light;
- and
- a Lenticular lens disposed on a surface of the Fresnel lens to change a path of the parallel light from the Fresnel lens, providing a three-dimensional image to a user;
- wherein the Lenticular lens includes a plurality of pixel lenses corresponding to pixels of the screen, each of the pixel lenses having a central diffusing portion formed on a light-outgoing portion and a peripheral diffusing portion formed on a peripheral portion of the central diffusing portion.
A projection display system comprising:
- a projector for generating an image;
- and
- a screen for converting the image from the projector into a three-dimensional image,
- wherein the screen includes:
- a Fresnel lens for converting incoming light into parallel light;
- and
- a Lenticular lens disposed on a surface of the Fresnel lens to change a path of the parallel light from the Fresnel lens and to provide a three-dimensional image to a user, the Lenticular lens including a plurality of pixel lenses corresponding to pixels of the screen, each of the pixel lenses having a central diffusing portion formed on a light-outgoing portion and a peripheral diffusing portion formed on a peripheral portion of the central diffusing portion.
