Da-Lite releases selection of screen surfaces

Da-Lite Screen Company, Inc. announced the availability of the widest range of high-contrast gray projection surfaces to the marketplace. Now, choosing the correct high-contrast screen for a fixed pixel projection device is even easier by selecting one of the following gray-based screen surfaces.

High Contrast Da-Mat

The first of Da-Lite's gray based surfaces has a gain of 0.8 and a 45 degree half angle. High Contrast Da-Mat is ideal for use with today's high-output LCD, LCoS(tm), D-ILA(r) and three-chip DLP(tm) projectors. This surface improves the perceived contrast levels by lowering black levels in settings where ambient lighting is controlled. High Contrast Da-Mat is available on Da-Lite's fixed frame and tab tensioned electric screens.

High Contrast Audio Vision

With the same optical characteristics as High Contrast Da-Mat, High Contrast Audio Vision is perforated to allow placement of a center-channel speaker behind the screen surface with less than a 5 dB loss at the 20k frequency and less than 1 dB at the 10k frequency.

High Contrast Cinema Vision

With a gain of 1.1 and a 45 degree half angle, High Contrast Cinema Vision is the perfect choice for installations utilizing single-chip DLP or LCD projectors with moderate output. With a gray-colored base material and a specially designed reflective coating, the High Contrast Cinema Vision fabric is designed to enhance the black level of projected images without sacrificing the white-level output. In addition, with enhanced contrast levels, the High Contrast Cinema Vision is good for settings where ambient lighting is moderately controlled. High Contrast Cinema Vision is available on Da-Lite's fixed frame and tab-tensioned electric screens.

High Contrast Cinema Perf

With the same optical characteristics as High Contrast Cinema Vision, High Contrast Cinema Perf surface is perforated to allow placement of a center-channel speaker behind the screen surface with less than a 5 dB loss at the 20k frequency and less than 1 dB at the 10k frequency.

High Contrast Matte White

The latest of Da-Lite's High Contrast surfaces has a gain of 1.1 and a 45 degree half angle much like the High Contrast Cinema Vision. With a fiberglass-based gray material substrate and a specially designed reflective coating, the High Contrast Matte White fabric enhances the black level of projected images while maintaining the white-level output. High Contrast Matte White is designed for use in applications where a tensioned screen is not needed.
