Gain |
A relative measure of a screen's reflectivity. |
Contrast |
The ability to accurately reproduce and differentiate light and dark characters and backgrounds, or light and dark areas of an image |
Ambient Light
Rejection Properites |
The ability to perform well under normal to adverse lighting conditions in the audience area. |
Resolution |
The clarity of the projected image. |
Uniformity |
The screen's performance when viewed from various points off the projection axis (both horizontally and vertically), and when the brightness of the center of the image is compared to the corners. |
Projection
Format |
The height and width of the projected image determines the screen's size and shape (AV, NTSC, HDTV, WideScreen, CinemaScope, overhead, slide or motion pictures). |
Textile Backed Screen Surfaces
In this group, the reflective surface is laminated to a woven textile base. The screen surface hangs suitably flat because of the stability of the material and the weight of the bottom dowel. Good for all types of projection. Commonly used for single lens video projection, as well as for CRT video and data-graphics projection.
Screen Surfaces
Matt White
A matt white surface diffuses projected light in all directions, so image can be seen from any angle. Provides accurate color rendition as well as superior clarity. Recommended for use with all high light output projection devices. Requires control of ambient light in the audience area. Washable, flame and mildew resistant. Seamless in virtually all standard sizes.
Gain: 1.0
Viewing Cone: 180 Degree Cone
Glass Beaded
Spherical glass beads embedded in surface provide brighter on-axis viewing than matt white, within a narrower viewing cone. Glass beaded surfaces have some loss of clarity and perform best with table-mounted projectors. Flame and mildew resistant; cannot be cleaned. Seamless in standard sizes through 10’ high.
Gain: 2.5
Viewing Cone: 45 Degree Viewing Cone
High Contrast Grey
Grey, textile-backed surface offers excellent resolution while enhancing the blacks of LCD and DLP projected images, even as whites and lighter colors are maintained. Performs well in ambient light. Lower gain of 0.8 allows use with even the brightest projectors. Available on most non-tensioned motorized and manual screens, seamless in sizes through 8' high. Viewing cone of 180°.
Gain: .8
Viewing Cone: 120 Degree Viewing Cone
AT1200
The most innovative and versatile acoustically transparent screen material. Similar in gain performance to Matt White and does not require tensioning for flatness. Acoustical properties comparable to the finest speaker grille cloth. Washable, flame and mildew resistant. Available in sizes through 72" x 96" or 10' diagonal. Not recommended for screens smaller than 80" wide when used with LCD or DLP projectors.
Gain: 1.0
Viewing Cone: 180 Degree Cone
AT Grey
Offers the acoustical properties of our popular AT1200, while providing the best optical qualities of both Matt White and High Contrast Grey. It is unique in that it offers both a 180° viewing cone and the vivid color contrast associated with high contrast grey materials. Washable, flame and mildew resistant. Gain of 0.8. Available in sizes through 72" x 96" or 10' diagonal. Not recommended for screens smaller than 80" wide when used with LCD or DLP projectors.
Gain: 1.0
Viewing Angle: 120 Degree Viewing Cone
