Abstract
A projection kiosk for a multi-projector digital signage system includes an enclosure and a frame disposed therein. The frame includes attachment points which can hold in position a plurality of projectors. The projectors may be aligned with sub-pixel-resolution accuracy to enable projection of pixel-aligned images onto a screen. The enclosure includes a heat ducting subsystem configured to direct air into the enclosure, duct air through the projectors, and discharge air away from a projection path between the plurality of projectors and the screen.
Claims20
A projection kiosk for a multi-projector digital signage system, comprising:
- an enclosure having a supporting base;
- a frame disposed within the enclosure having attachment points configured to hold in position a plurality of projectors configurable to be aligned with sub-pixel-resolution accuracy to enable projection of pixel-aligned images onto a screen;
- and
- a heat ducting subsystem disposed within the enclosure and having (i) an intake to accept air external to the enclosure, (ii) baffles to direct air through the plurality of projectors, and (iii) an air discharge positioned to direct air away from a projection path between the plurality of projectors and the screen.
A method of making a projection kiosk, comprising:
- forming an enclosure;
- installing a frame within the enclosure having attachment points configured to hold in position a plurality of projectors configurable to be aligned with sub-pixel-resolution accuracy to enable projection of pixel-aligned images onto a screen;
- mounting a plurality of projectors within the frame;
- and
- installing a heat ducting subsystem within the enclosure, the heat ducting subsystem having an intake to accept air external to the enclosure, baffles to direct air through the plurality of projectors, and an air discharge positioned to direct air away from an area between the plurality of projectors and the screen.
A method of projecting images onto a screen using a plurality of projectors, comprising:
- providing an enclosure having a supporting base and a plurality of projectors mounted therein;
- projecting an image onto the screen having image components projected from the plurality of projectors;
- aligning the image components with sub-pixel-resolution accuracy;
- and
- guiding heat generated by the plurality of projectors away from a projection path between the plurality of projectors and the screen.
