Abstract
A projection screen is provided, which includes a reflective layer having plural reflective patterns which are spaced apart from one another and each of which includes an image reflective surface having an inclination angle against a horizontal direction so as to guide an image light toward a front of the screen, and plural external light absorption layers absorbing external lights incident to the screen.
Claims19
A projection screen for displaying an image projected from a projector comprising:
- a reflective layer having a plurality of reflective patterns which are spaced apart from one another, wherein each of the plurality of reflective patterns includes an image reflective surface having an inclination angle against a horizontal direction which guides an image light toward a front of the screen;
- and
- a plurality of external light absorption layers which absorb external lights incident to the screen,
- wherein the reflective layer has a plurality of absorption layer seating surfaces on which the external absorption layers are disposed, and
- wherein each of the plurality of the absorption layer seating surfaces is arranged in a space disposed between and separating a base of two adjacent reflective patterns.
A projection system including a screen and a projector projecting an image onto the screen, wherein the screen comprises:
- a reflective layer having a plurality of reflective patterns which are spaced apart from one another, wherein each of the plurality of reflective patterns includes an image reflective surface having an inclination angle against a horizontal direction which guides an image light toward a front of the screen;
- and
- a plurality of external light absorption layers which absorb external lights incident to the screen,
- wherein the reflective layer has a plurality of absorption layer seating surfaces on which the external absorption layers are disposed, and
- wherein each of the plurality of the absorption layer seating surfaces is arranged in a space disposed between and separating a base of two adjacent reflective patterns.
