The Effect of DLP Projector White Channel on Perceptual Gamut
  DOI :  10.2352/CIC.2005.13.1.art00038  Published OnlineJanuary 2005

The effect of white channel enhancement as implemented in the Texas Instrument DLP digital projector technology is evaluated theoretically using both the CIELAB and the CIECAM02 color appearance models and experimentally through psychophysical testing using real images. Both theory and the test results confirm a compression of perceptual gamut in both chroma and colorfulness as a result of the added white channel. Hence, while this technology is ideal for viewing graphics and text under ambient conference room conditions, it is necessarily less than ideal for viewing images or in home theater environments.
