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.
