DP Announces Brilliant Color Technology For Single-Chip Projectors

May 17, 2007

Brilliant Color, currently available in dVision 1080P projectors, will be rolled out for all DPI single-chip projectors over the next couple of months. The primary benefits of Brilliant Color technology are increased projector brightness and improved color saturation and/or color gamut. These performance improvements are achieved by adding 3 additional colors to the color wheel of single-chip DLP® projectors. DP will offer three different color-wheel implementations of Brilliant Color: Enhanced Color (EC) - Optimized for maximum color saturation and gamut Enhanced Brightness (EB) - Optimized for maximum spectral brightness Balanced (B) - Optimized to strike the best balance between maximum color and brightness. The core principle at work is the same among all 3 versions. In current single chip projectors, the existing color filters for red, green and blue are used to maximize brightness, but don’t allow for high color saturation - especially the yellow and cyan shades found in many natural scenes. By adding cyan, magenta, and yellow filter segments to the color wheel, additional spectral energy from the lamp is captured, thus increasing projector brightness. Also, the projectors’ color space (gamut) can be expanded to allow for a broader range of more saturated colors without sacrificing light output. In fact, depending on the BC color wheel employed, overall projector light output can be increased from 2% to 50% and still produce richer golds, cyans, and reds. Even basic RGB color wheel projectors can benefit from Brilliant Color technology. In typical RGB color wheels, the primary colors are divided into segments separated by small clear spokes. In a Brilliant Color equipped RGB color wheel, these transition areas are a combination of the two adjacent primary colors. For example, yellow is placed in the spoke dividing red and green, cyan in the spoke between green and blue, and magenta between red and blue. Previous technology could not take advantage of these colors, therefore they would not be passed to the DMD. The new Brilliant Color technology captures these transition colors, adding small but significant brightness and color point capability to the light engine. Our current dVision 1080p utilizes Brilliant Color with a 7-segment RGB color wheel, but will migrate to an optional 6 segment RGB-CMY color wheel around infoComm. New versions of the popular iVision20, dVision and a new iVision 30 series will be offered with the 3 Brilliant Color options around infoComm as well. Customers can expect to see the details regarding the various color wheel configurations on DP’s price list at infoComm. We will endeavor to stock projectors equipped with the Brilliant Color performance that offer the broadest application appeal for our customers. The more niche oriented Brilliant Color products will be available on a special order basis.
