DMD (digital micromirror device) panels that provide digitized red, green, or
blue color information. Light from the ON pixels of each panel is reflected,
converged and then projected to the screen through a single front lens, where all
pixels are perfectly superimposed as a sharp full-color image.
The projector enclosure is comprised of a combination of metal panels,
extrusions and polymer bezels. Separate access doors and grill panels are easily
removed for...

Curved screens have gains larger than 1 (due in part to the screen material) and
viewing angles much less than 180°. Most curved screens have different
horizontal and vertical viewing angles. Incident light does not reflect equally in
all directions. The reflected light concentrates in a conical volume or viewing
cone. Audiences within the viewing cone see...

To summarize, optical screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone. Diffused screens are best suited
when a wide viewing angle is required but there is low ambient room lighting.
Screen size may be from 6 to 40 feet diagonal, depending on the lens you are
using. For instance, a 1:1 lens produces a 6-30 foot image size, whereas a 4-7:1
zoom lens produces a 10-40 foot image size. Choose a screen...

Even with all lighting removed it is still possible that room reflections within the
room can slightly degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to
the screen. Again, keep reflective surfaces to a minimum.
Here are some other considerations and tips which can help you improve your...
