Under 'Tension'? A Front Projection Tutorial
September 14th, 2010
Da-Lite offers most of its Wall and Ceiling Mounted and Ceiling Recessed screens in both non-tensioned and tensioned configurations. These include the Contour® Electrol®, Cosmopolitan® Electrol®, Advantage® and Advantage Deluxe Electrol®, Professional Electrol®, and Executive Electrol® series of screens.
Why is tensioning important in front projection screens? Without constant tension applied horizontally and vertically, screen surfaces are prone to slight surface non-uniformity. This can result from air movement around the projection screen and non-uniform stretching as the screen ages. With most projection applications, slight non-uniformity doesn't dramatically affect the projected image. In HD projection, home theater, large screen applications and other critical viewing environments, tensioning provides near-perfect surface uniformity.
In tensioned configurations, a tab guide cable system of tensioned screens maintains uniform lateral tension to hold surface flat while the custom slat bar with added weight maintains vertical tension.
