Abstract

The widespread use of data projectors in more demanding imaging applications has emphasized the need for accurate methods of their color control. Projectors are relied upon in settings where color reproduction is increasingly important, such as digital cinema, and business applications including advertising and presentations using such color-critical items as corporate logos. We have measured and characterized a set of such data projectors, using both liquid crystal display (LCD) and Digital Light ProcessingTM display technologies. (DLPTM, trademarked Texas Instruments.) LCD projectors are successfully modeled using established techniques for LCD projectors and display screens as typically found in laptop computers. For the DLP devices, the LCD model is extended using a previously-proposed model in combination with a new method for calculating the amount of white channel addition. Colorimetric results are presented for both types of display technology for a series of projectors, with the more complex DLP modeling performing as well as the simpler LCD modeling.
