ATLANTA, GA - JUNE 17, 2009 - Digital Projection International (DPI), an Emmy® Award-winning manufacturer of high-performance projection systems, announced today that their entire single-chip projector line is now available with VIDI technology. DPI offers over 35 products within their iVision 20 and iVision 30 projector platforms, along with seven distinct dVision models. Incredibly bright for their small size, iVisions produce up to 3700 lumens and 5000:1 contrast while the dVisions produce up to 6500 lumens and contrast ratios of up to 7500:1.
VIDI is a Philips innovation developed in close cooperation with Texas Instruments in order to optimize the image performance of DLP-based projectors for both video and data applications. VIDI electronics activate the UHP lamp by way of a two-pulse system: one brilliant pulse and one dark pulse. The dark pulse enhances contrast, providing a smoother, more vivid image, while the brilliant pulse boosts brightness by up to 25% to 30%. The brilliant pulse ensures there is a noticeable increase in the brightness of the projected image.
The engineering collaboration between Texas Instruments and Philips in VIDI technology equips the projection electronics to pulse either an individual color or mix of colors by synchronizing the pulsing of the lamp with the cycling of the projector's color wheel. For example, if more red is desired, an integrator can choose to "boost" the lamp output (pulse the lamp output) during the red interval of the color wheel. Therefore, red illumination energy can be 25-30% brighter without increasing the demands on the lamp or impacting lamp life. By creating a "dark" pulse, grey scale can be improved by up to 2 bits, along with an increase in projected contrast ratio and a reduction of dither noise by as much as 75%.
Different pulse combinations can be created to optimize projector performance for specific applications. VIDI technology allows color wheel-based projection systems, like DPI's iVision and dVision series, to improve performance and flexibility without negatively affecting projector thermal output, power consumption or lamp life.
Digital Projection International will be exhibiting their full range of powerful, efficient and responsible DLP projectors, including the new iVision and dVision VIDI units, at the upcoming InfoComm tradeshow in Orlando, Florida at booth number 2861.
