Projector Buyers Guide to

Color Brightness by Model

Projector buyers should proceed with caution.

Derived when presentations consisted of a blackfont on a white background, the old lumens metric

only measures white light. Lumens, or brightness,tells the projector buyer little about the brightnessof colors in photos, videos or graphics.

Fortunately, a newer metric gives projector buyers ameasurement for the brightness of colors. ColorLight Output, or more simply Color Brightness,quantifies the brightness of Red, Green and Blue;the primary colors of light.

The photograph below shows two projectors setupside-by-side, set in their brightest mode. Both offer

similar resolution, price and white brightness levels.

The projector on the left exhibits low Color Brightness;only a fraction of its white brightness. The one on the

right shows equal amounts of Color and White Bright-ness. Colors on the right are much brighter, providingmore impact.

This document starts with a listing of projectors wherethe manufacturer specifies both White and ColorBrightness. Second is a table containing projectorsmeasured for their Color Brightness level by a 3rdparty laboratory because the manufacturer did notspecify the color brightness.

Insist on brighter colors. When selecting a projector,

consider both the brightness of White as well as thebrightness of Color.

Low Color Brightness High Color Brightness1

Whats behind this new Color Brightness metric?

Color Light Output, or simply Color Brightness, measures the illuminance of the colorprimaries Red, Green and Blue. The technical details of this measurement methodologyare defined in the newly available Information Display Measurements Standard publishedby the Society of Information displays.

The authors of this important standards document were volunteers from all corners of thedisplay industry. These experts carefully examined each of the nearly 200 display metricsin the document to make sure each was relevant, scientifically valid, and worth including inthe document.

The Society of Information Displays (SID) is a globally recognized organization working tohelp educate technical members of the display industry. SID was founded as a ProfessionalSociety back in 1962. SID is made up today of about 5,000 display professionals.

More information about this document can be found at: http://www.icdm-sid.org/

Why does the metric only measure Red, Green and Blue? What about all the other colors?

Computers and media players define colors as relative levels of Red, Green and Blue. For example, yellow is stored inside tcomputer as bright red, bright green and no blue.

Regardless of how the projector may create its image, the standard input signal is based on Red, Green and Blue and therefore its important to measure these standard color primaries.

What does the Brightness metric weve used for years represent?

Brightness, or technically Light Output, is only a measurement of white light. To measure brightness, projector makers willtake nine brightness readings. The nine readings are made across the entire image. The average of the nine measurementis then multiplied by the screen area in square meters to determine the projectors lumen output.

How is Color Brightness measured?

Color Light Output is measured almost exactly the same way as Brightness or white light outputbut instead of measurinwhite light, the primary colors are measured.

Instead of just nine measurements, there are total of 27 measurements taken, with the three sample images below.

The brightness of Red, Green and Blue are averaged, summed and multiplied by the screen area to determine the totalamount of Color Brightness.

1. Actual photographs of images produced by two competing projectors set to the brightest mode. Price and resolution are the same for both projectors. Projector on the left is a1-Chip projector rated by the manufacturer at 2700 lumens of White Brightness; it measured 700 lumens of Color Brightness. The projector on the right is a 3LCD projector rated at2600 lumens (Color Brightness) and 2600 lumens (White Brightness).

2. The data in Table 1 was obtained from Projector Central based on information available from these manufacturers.

3. The White Brightness data in Table 2 was obtained through Projector Central, as specified by the manufacturers. These manufacturers do not provide Color Brightness (Color LighOutput) data. Color Brightness was determined in compliance with IDMS 15.4 by 3rd party laboratory test ing of a single unit of each model. Serial numbers available on request atTim.Anderson@3LCD.com.
