EpsonEpson Mini LED projector introduction using LED light source : Epson today announced that it had succeeded in developing a prototype postcard-sized mini-projector using an LED light source. With a footprint of just 13.8 centimeters by 10.3 centimeters (just smaller than a sheet of A6 paper) and a slender profile, the 500-gram prototype can fit easily into the palm of your hand. The Epson LED mini-projector can be viewed at first hand by visitors to the IFA 2005 trade show to be held in Berlin, Germany, from September 2 to 7. Although the company has no immediate plans to market the mini-projector, company representatives believes that the prototype demonstrates just how compact mobile 3LCD projectors could one day become.

"Projector using 3LCD technology have advantages in terms of bright, natural images that are easy on the eyes," said Koichi Kubota, general manager of projector marketing at Epson. "This development is yet another example showing the potential of Epson projectors and Epson projector technology." With 11.3% of the share for front projectors in 2004, Epson's popular range of projectors for education, business and home entertainment make the company the global market leader.

Epson Mini Projector - LED advantages
In addition to allowing ever more compact design, LED light sources provide several advantages over conventional lamps including immediate projection readiness, a long running time, and swift switch-off. The use of an LED light source in a projector is a first for 3LCD. The current development is the latest in a long series of technical breakthroughs for Epson projectors. One of the very first companies to enter the projector market, Epson has stayed ahead of its competition by continually providing features and technologies that offer users real benefits. Recent developments include Crystal Clear Fine (C2 Fine) technology that dramatically enhances aperture ratios, definition, and image quality to enable the development of 3LCD projection TVs offering an even more realistic viewing experience. The company will continue to place top priority on developing market leading projection projects for a wide variety of applications and locations.

Mini 3LCD projector - What is a 3LCD projector?
Liquid Crystal Display (LCD) projectors pass light through LCD panels about the size of a postage stamp; the LCD panel is made up of miniscule panels ('pixels') that can be clear, opaque or some semi-clear point in between. These pixels take the form of the image to be created, and the light passes through the clear or partly-clear areas in the same way that light passes through the clear or gray parts of a negative. The projector's lens, in turn, expands the image and directs the light onto the screen or viewing surface. This enlarges all the tiny details and creates clear, detailed and beautiful images with ultra-smooth movement.

Epson Mini-Projector - DLP projector
After the 3LCD projector system, the second most common type of business projector is the 1-chip DLP projector system. These 1-chip DLP projectors create pulses of colored light by shining lamplight through red, green, blue and white parts of a rotating wheel. These rapid pulses - thousands per second - are then reflected by a DMD device. The DMD device has one tiny mirror for each pixel in the image. It is on a hinge, and flickers rapidly. The series of rapid color bursts are then projected on the screen and seen in rapid succession. The viewer's brain can't pick out the individual flickers, but instead mixes the basic colors that appear one after the other in each pixel to come up with the final color the viewer sees.

Epson projector - Bright Images
Enjoy beautiful color in clear, defined images that are easy on the eyes, even in a bright room. In internal testing we found that Epson 3LCD projectors consistently yielded brighter red, green and blue over top selling 1-chip DLP projectors using similar lumens ratings. 3LCD projectors can project bright, vivid images with a low output lamp that uses less electricity. And that means less heat and less cost to run. That's technology that is also friendly to the environment.
