3LCD Projector Technology

3LCDWhen it comes to projector technology, image quality is the hallmark of excellence. When powerful images are a must, so is an Epson 3LCD projector. Projectors that use 3LCD technology are easy on the eyes because they reproduce beautiful images in bright, natural colours with smooth motion and no colour break-up.

Broadening the reach of 3LCD projectors

3LCD projectors continue to be the most widely used projectors In the world. More than 11.3 Million front projector units have been sold worldwide over the past 17 years.


Why Choose a 3LCD Projector

  • Bright Images
    Because 3LCD projectors continuously project Red, Green and Blue colours, images are bright and colourful. Our internal testing established that Epson 3LCD projectors consistently yielded brighter Red, Green and Blue colours than 1-Chip DLP™* projectors with similar lumens ratings. Every colour is faithfully reproduced by 3LCD projectors with dynamic brightness, vibrant and accurate colours that breathe life into any presentation, whether for high profile business seminars, movies or the latest gaming console. 3LCD projectors take image quality to its natural best.
  • The Luminance of Colours
    Maximum brightness ( i.e. lumen level indicated on brochures ) is measured by projecting a 100% full white pattern image to a screen. However, in a true presentation scenario, images with colour are projected, meaning that the true lumens of each colour is extremely vital in such situations.
  • 3LCD projectors offer superior colour luminance, producing vivid and sharp colour images. This capability enables them to provide more effective support than ever before in business presentations, which increasingly make use of colour in images such as photographs and charts.
Luminance of Colours
  • Lower Power Consumption
  • 3LCD epson projectors offer greater power efficiency, resulting in energy savings.
  • Many 3LCD projectors use lower wattage lamp (E-Torl) than those of comparable 1-chip DLP projectors with a similar lumen rating. This results in less power consumption and greater energy savings.
Power Consumption
  • Natural Images
    3LCD projectors can project a very wide range of colours. Smooth movement in the microscopic liquid crystals in LCD panels allows for natural colour changes, especially in darker parts of images. Conversely, due to limited gradation of darker shades, many 1-Chip DLP™* projectors cannot faithfully reproduce subtle colour changes, resulting in a visual distraction called "Dither Noise". This is not an issue with 3LCD projectors.
  • Gentle on the Eyes
    3LCD projectors reproduce images that are easy on the eyes. These images will not have colour break-up (or "rainbow effect"), which may be seen with 1-Chip DLP™* projectors. The "rainbow effect" is a result of colour sequential technology which can be distracting to viewers. In short, with 3LCD projectors, you will be sure of thoroughly amazing, enjoyable images.
  • Smooth Motion
    3LCD projectors use three separate liquid crystal panels - Red, Green and Blue - to form a continuous image containing all colours. This means that even rapid motion video will appear smooth. With 1-Chip DLP™* projectors, viewers may see multiple lines or blurry images in rapid motion video.
  • High Reliability
    3LCD projectors use no moving parts in the light control system, which makes it highly reliable over many years of operation.

Inside a 3LCD projector

3-panel LCD System. Technology by Epson

Light is separated into Red, Green and Blue beams by stationary mirrors. Each colour passes through an LCD panel which creates shades of that colour. Single colour images are combined by a prism to create a full colour image in the projector, which then passes through a lens onto the screen. A 3LCD projector has no moving parts in the light control system and projects a full colour image with smooth motion and no colour break-up.

Inside a 1-Chip DLP™* Projector

The second most common projector technology is 1-chip DLP™*. In this system light passes thought a rapidly spinning colour filter, where is is broken down into sequences of Red, Green, Blue and White. The image is formed by each colour in turn reflecting off thousands of tiny hinged mirrors through a lens. A 1 -Chip DLP™* projector has thousands of moving parts. It projects a rapid sequence of Red, Green and Blue images that are combined by the viewer's eye/brain to create the impression of a full colour image.
