Comparing 1-chip DLP with 3LCD technology

A 1-chip DLP projector relies on a single microdisplay chip and a spinning color wheel. At any given instant, the system displays either red, green or blue. Shown rapidly, our brain combines these individual colors into one image. However, viewers may see flashes of individual colors – the rainbow effect – particularly across dark areas or fast action in a video.

Has this happened to you? You look forward to an important presentation – only to find yourself struggling through a series of poor quality projected images? Perhaps under dimmed lights, with drawn shades? Under these conditions, it’s difficult to read text and make out images. Concentration tends to wane – not only spoiling your focus, but also your understanding of the subject.

What’s more, you may have suffered with tired, irritable eyes – which is the unfortunate consequence of what’s known as the “rainbow effect”. Read on for details of this effect. This problem is inherent in 1-chip DLP projectors and, with prolonged viewing, might also cause headaches.

With a 3LCD projector, white light is first split into red, green and blue beams. Each beam is then filtered through its own individual LCD, which gives images the exact brightness for each color. The color beams are then perfectly recombined in a prism before being projected as a complete image. No spinning wheel. No rainbow effect. Just a comfortable viewing experience.

More benefits of 3LCD over 1-chip DLP

A wider range of colors for a more lifelike display. The range of colors displayed by a projector is called a “color gamut”. The wider it is, the better the images. 3LCD projectors have a color gamut 3 times wider than 1-chip DLP projectors.

Superior color balance for 3x brighter images. The specifications of the 1-chip DLP projector may only reflect its white light output. Even if a projector has high white brightness, it may have low color brightness where your images would turn out dull and dark. 3LCD projectors have equal color and white output levels; ensuring faithful images with superior color balance.

The high color brightness of a 3LCD projector delivers images with vibrant and realistic hues – and there’s no need to dim the room. So, be it at work, in the classroom or at home, users can have a better experience when viewing with 3LCD projectors. All of these benefits add up to projections that are exceedingly vibrant, clear and realistic.

However, with customer budget restraints and confusion about what’s available in the marketplace, the tendency is to go for cheaper 1-chip DLP projectors. A demonstration of a 3LCD projector will quickly highlight its advantages.

3LCD projectors – the technology that people prefer

In an independent study conducted by Radius Research in the US the high color brightness advantages of 3LCD projectors were overwhelming. When tested against 1-chip DLP projectors, nine out of 10 people preferred the images achieved with Epson 3LCD technology.

So, why compromise your vision, when you can enjoy bright, realistic images in all your projected presentations? Do away with 1-chip projectors and wow your audiences with a new level of projected excellence.
