CES 2009: LED projector to develop more possibilities for consumer markets

The projector for human use, with 3LCD, DLP and LCoS projection technology, although the color projection principle is different, but most of the high pressure mercury lamp or a halogen lamp is white light, and then through the dichroic mirror, a panel or color wheel etc. will be separated into R, G, white B color. But in the face of modern "portable" demand, the traditional projection method has been unable to reduce the size of the projector. Therefore, LED replace the traditional light bulb is one of the solutions to the miniaturization of the projector.

As the projector to change the use of R, G, B tricolor LED light source, LED light source is small, with DLP, LCoS and other technologies can effectively simplify the structure of the optical system, making the projector to achieve thin. In addition, the use of LED light source in addition to the appearance of the projector becomes more compact at the same time, also has many traditional light sources do not have the advantage, such as the LED semiconductor characteristics, can quickly switch with projection and no noise, LED life is long and the traditional light bulb, the user does not need to replace the light bulb.

However, the brightness of the problem is still the biggest obstacle to the application of LED in projector. At the same time, the requirements of the screen resolution and light seems to be both can not have both, the future with the LED luminous efficiency is possible to achieve.

In 2009 1/8~1/11 in Las Vegas at the CES 2009 Exhibition, the projector manufacturers have demonstrated the micro projection technology of LED, most weight below 1Kg, very suitable for business people to carry out brief use. Even some manufacturers can also be combined with the use of projection technology mobile phone, so that portable and portable projectors to bring more possibilities for the consumer market.

CES 2009 Toshiba to showcase the latest LED projector TDP-F10U in CES 2009 Exhibition, Toshiba TDP-F10U mobile LED projector display debut, nothing like it in two, and other pockets of the size of the projected SVGA, 800 x 600 resolution, 800:1 contrast and color color projection of up to 16.77M. Toshiba TDP-F10U weighs 1.4 pounds (about 1.4 pounds) of about 635 grams, size for a paperback novel size. With LED light source can provide 100 lumens brightness. From the use of the situation, 100 lumens brightness projection of about 50 inches of the screen is still possible, a little attention to shading can be.

Toshiba TDP-F10U can provide users with reliable projection enjoyment on the trip. It is reported that the product will be listed in 2009 of March, the price of $599.

CES 2009 hung rhenium Technology (honlai) display pocket size miniature LED projector MP-100 hung rhenium technology in the CES conference released a model for the MP100 LED Mini projector. LCoS micro projection technology, with the 5W LED light source provides 15 lumens brightness, projection of the size of 5 to 37 inches VGA resolution (640 x 480) screen. With AV / VGA image input, can be used with NB/Mobile Phone/DVD Player and other products, although the contrast value is only 200: 1, but the weight is only 300g, it is worth looking forward to. CES 2009 Atlantis released the first palm sized micro LED projector APSE-10AAtlantis released the first micro LED projector APSE-10A. Although only palm size, weight of about 100g, but it can be projected 50 inch screen, resolution of about VGA level (640*480), suitable for business people out of the briefing purposes, or outdoor movies and other purposes. Atlantis also published a venue with GSM mobile phone mini projector APMP-N70, but there is no detailed specifications. CES 2009 Vivitek display LED source enterprise 1080p projector though there are many projectors to start using LED thought source, but the vast majority have seen, are compared in micro fields. In the 1080p rating of the projector, it is rarely seen, let alone the enterprise grade 1080p projector.

Vivitek in the launch of the first LED light source using the 1080p projector HC 7500A, this DLP projector, with a curve, lens design, asking price $13999. Brightness of 700 lumens, compared to 35000:1, LED light source life of more than 20000 hours, will begin in June 2009.

LEDinside view

The long term, LED projectors will have more applications not only in the mobile phone, portable digital playback devices such as portable consumer electronics market space, notebook computer, projector and projector with the office, home, or even business projector, there will be more and more high visibility.

With the improvement of the efficiency of the LED light source, it is inevitable that the projection light source is becoming more and more mature. As the problem is overcome, the light source of the LED projector will become one of the new exports of LED output in the LED.
