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 DLP 3-chip 3LCD

The DLP projector’s color brightness is

only 21 percent as much as the 3-chip

3LCD projector.

Color Brightness:

What It Is, Why It Matters

PC MAGAZINE • May 7, 2013

By M. David Stone | May 7, 2013

As you may have noticed, there's a

(relatively) new spec for projectors in town,

variously called color brightness, color light

output, or simply CLO. Whatever you call it, is

has an excellent pedigree, as part of the Infor-

mation Display Measurements Standard

version 1.03 (IDMS 1), dated June 1, 2012.

IDMS 1 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

Electronics Standards Association (VESA). All

of which makes it a pretty definitive standard.

As you may also have noticed, Epson recently

began touting its LCD projectors as having

three times brighter colors than "leading com-

petitive projectors." The claim also applies

more broadly to any projector using 3LCD

technology, which means a light engine with

three LCD chips, with one each for the red,

green, and blue primary colors.

The competition Epson is referring to is the

universe of DLP projectors that use a single

DLP chip (which I'll refer to simply as DLP

projectors). The claim is based on the typical

difference in color light output between a 3LCD

projector and a DLP projector that both have

equal brightness in ANSI lumens, which mea-

sures white light output. The problem with the

claim is that although it's both true and mean-

ingful, it's also easy to misunderstand.
