Summary excerpts
Color Brightness: What It Is, Why It Matters
“Color brightness, color light output, or simply CLO...has an excellent pedigree, as part of the
Information Display Measurements Standard ”
“Differences in image brightness are a big part of why color
brightness is worth knowing about”
“What these results confirm is that, as a practical matter, if you're showing primarily black and
white images like word processing documents or spreadsheets, DLP and LCD projectors with the
same ANSI lumen measurements will both be equally bright. For color images however, whether
PowerPoint slides or photos, the LCD projector will be brighter.”
“The difference in color brightness, however, was huge, with the LCD projector delivering essen-
tially the same number for color brightness as for white brightness, and the DLP projector
coming in at just 680 lumens, or about 21 percent of its measurement for white light.”
“Almost all (DLPs) boost their brightness for white light-
-which is what ANSI lumens measures--by adding one or
more additional panels beyond red, green, and blue”
“[The standard] was developed by the International Committee for Display Metrology (ICDM),
which is part of the Society for Information Display (SID), in cooperation with the Video Elec-
tronics Standards Association (VESA). All of which makes it a pretty definitive standard.”
1-chip DLP3-chip 3LCD

only 21 percent as much as the 3-chip
