Though currently less bright than their lamp-based counterparts, LED displays are perceived as being much brighter than their measured luminance specifications, thanks in part to the Helmholtz-Kohlrausch effect (H-K effect). The International Electrotechnical Commission defines the Helmholtz-Kohlrausch effect as, "A change in brightness of perceived color produced by increasing the purity of a color stimulus while keeping its luminance constant within the range of photopic vision." In layman's terms, the H-K effect describes a situation whereby if two color stimuli sources with the same luminance are compared, the perceived brightness induced by the color stimuli of higher purity will be higher than that of lower purity. LED illuminated projectors produce extraordinarily high color purity and saturation, thus appearing brighter than a lamp-based display with similar measured lumen specifications.
LED projectors are ideal for critical 24/7 projection applications, as well as any application needing long-life projection systems with unmatched color saturation, lumen maintenance and color stability. As LED projectors do not enlist a traditional lamp, applications utilizing DPI's higher-lumen M-Vision LED and dVision LED displays will benefit from their Lifetime Illuminationâ„¢ 60,000+ hour lifespan. DPI's Lifetime Illuminationâ„¢ certification ensures that their LED projectors will deliver many years of consistent, engaging and virtually maintenance-free imagery for the application in which they're installed. Providing 3-chip color saturation from small-form single chip displays, M-Vision LED and dVision LED displays present powerful, capable solutions for a variety of commercial and residential applications including command and control, home media, visualization and simulation where image quality, long-life and low long-term cost of ownership are equally valued.
A combination of consistently stable, long-term light output and a supremely low-maintenance illumination system defines DPI's LED display solutions. In each of Digital Projection's LED displays, the RGB-based LED illumination system eliminates the need for a color wheel to produce primary colors. Instead, red, green and blue LED's produce primary color illumination, rendering a color gamut and color saturation similar to that of a 3-chip DLP projector with no color wheel artifacts. Additionally, certain LED displays in DPI's product line feature their FastFrame technology, which assures fast-moving content appears remarkably sharp and free of motion smear. As is the case with every projector in their catalog, DPI's LED displays utilize Texas Instruments' DarkChip DLP technology, ensuring unmatched black levels, RGB bit depth and dynamic range.
DPI will be demonstrating numerous 2D, 3D and LED precision projectors throughout a completely reconfigured booth (#3454) at CEDIA Expo 2012 from September 6 – 8 in Indianapolis, Indiana.
