Digital Projection International (DPI) projectors are now available with VIDI technology, a Philips innovation developed in cooperation with Texas Instruments to optimize the image performance of DLP™-based projectors for both video and data applications. The 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 smooth, vivid image, while the brilliant pulse boosts brightness by 25% to 30%. The brilliant pulse ensures there is a noticeable increase in the brightness of the projected image. The 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. Different pulse combinations can be created to optimize projector performance for specific applications.
