When it comes to REAR-PROJECTION, the POP-contrast screen supply the best overall picture by NORMAL circumstances.
Normal circumstances will be:
-
Distance (focal lengh) from projector to screen is minimum 1:1,2
-
The projector shoot in an angle of approx. 90° to the screens surface in both directions
-
The grey tint of the screen enhance the images contrast an supply better colour-saturation than a white screen
-
Mat surface toward the viewer secure no reflections from surroundings disturb the image
-
Mat surface toward the projector secure the "incoming" light from the projector in the screen-corners will be "soaked" and not reflected. By long projection-distance a mat surface toward the projector is a disadvantage, because the mat surface also "soaks" lights from surroundings.
If circumstances are not normal, DAF Screens A/S as MANUFACTURE, can adjust many of the parametres when casting the screens from liquid acrylic:
-
The tint can be changed
-
The "diffusion-particles" can be changed
-
The quantity of "diffuusion-particles"
-
The size of "diffusion-particles" can be adjusted
-
The surfaces can be changed
Projectors and applications has been changed during years and as a consequence, DAF Screens A/S has made a line of screens for different circumstances. Kind look at our other POP-screens.
The manufacturing up on requst implify extra work and attention, so minimum-quantity is required. If you have an interest for such OEM-products, do not hesitate to contact kim@dafscreens.com |
