EPSON 3LCD TECHNOLOGY – FOR BRIGHT, FAITHFUL COLOURS
3LCD projectors offer brighter and more accurate colours as they produce
different shades and hues by filtering, then mixing beams of the three primary
colours (red, green and blue).
In a 3LCD projector, white light is first split into the three beams of primary
colours. Each beam is then filtered through its own LCD that will give each
individual pixel of the image its exact brightness for each colour. The colour
beams are then perfectly recombined in a prism before being projected out as a
complete image.
What is Colour Brightness?
As the term implies, Colour Brightness is a new international standard that
states a projector’s colour light output in lumens. It measures the brightness of a
projector’s red, green and blue light.
These are the measurements to look for:
Colour Brightness - Colour Light Output
White Brightness - White Light Output
How to Find a Projector’s Colour Brightness?
1. Look for separate Colour Brightness and white brightness specification.
2. Projectors with similar white brightness levels can have vastly different and
significantly lower Colour Brightness levels.
3. Manymanufacturersmaynotwantyoutoknowtheirprojectorsareonly1/3
as bright when measuring colour.

3LCD projector : RGB are projected at the same time, which makes the single composite image easy on the eyes.
This compares to projectors using single-chip technology that actually project
individual colours sequentially by filtering their single white light beam through
a colour wheel, and then relying on human colour perception to combine the
colours in the viewers’ minds.
As a result, 3LCD projectors also offer greater detail, smoother gradations, no
“colourbreakup”effect,areeasieronviewers’eyes,andconsumeabout25%
less power to achieve the same brightness compared to a single-chip projector
using a lamp of the same wattage.

A New Specification
Projectors have always had their brightness rated only for white light. However,
they may have very different colour brightness levels. The Colour Brightness
specification provides a new way for buyers to compare the holistic performance
(white and colour light brightness) of projectors to make a more informed
decision.
Why Does Colour Brightness Matter?
Even if a projector has high white brightness, it’s Colour Brightness could be

has high Colour Brightness, you’ll see vibrant, realistic colours; but if Colour
Brightness is low, colours can look dull and dark, skin tones can be reproduced
poorly and important details can be lost.
