Projection Screen - Automated

Why choose an Electric Screen? A motorized screen gives your room maximum flexibility. The screen may be chosen to blend with its surroundings, or be recessed in the ceiling to completely disappear when not in use. The screen’s controls are usually integrated with the master control for the home theater.

Electric Screens can be tab-tensioned, or non-tensioned, ceiling-recessed or wall mounted. The tab tensioning system for vinyl surfaces consist of a reflective vinyl with no textile backing. This is tensioned with a complex tensioning system, resulting in a flatter surface and better picture quality. Non-tensioned motorized screens are referred to as free hanging or conventional: 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.

There are 2 additional projection screen enhancements that can give a motorized projection screen “extra sizzle”. The first is an acoustically transparent screen that allows the center channel to be place behind the screen. This adds realism (it seems as though sound is actually coming from the actor … not a different location). The second is vertical and horizontal masking (lengths of black fabric that frame the viewing surface) that allows the screen to be placed perfectly in relation to the viewer and the room.

There are four main categories of screen surfaces:

• Matte white: This represents a surface with less than 5% reflectivity; black is very dark gray to black but the image is not very bright.
• Pearlescent: Surface reflectivity is typically 15%; black is dark gray and image is bright, provides best overall contrast.
• Silver/Gray: 30% reflectivity; black is medium gray and image is very bright, dark colors may seem a little dull.
• Glass bead: This represents the surface with the highest level of reflectivity - typically 40%; black appears as light gray and image is usually too bright. Normally, this type of projector screen surface is used only under special circumstances.

Finally here are a few basic criteria that you have to consider to arrive at the right projector screen surface. This is necessary as different projection screen surfaces are designed to handle each of these basic criteria in a somewhat different manner. These criteria include: Projection Method, Ambient Light Conditions, Display Brightness, Room Configuration and Size, Projected Image Make-up, Projector Placement, and Screen Maintenance.
