LED light source and single chip system will become a nightmare 3LCD?

DLP and LCOS challenge the success and failure of 3LCD

Digital projector technology has formed 3LCD, DLP and LCOS three foot full situation. As the longest can be investigated for 30 years of history of 3LCD projection technology has been rumored to be replaced by news. The first is the challenge of DLP on 3LCD, followed by LCOS turned out, and then I'm afraid there will be other successors to take up such an important task".

Why do we have to talk about 3LCD being replaced? There's a reason. From the global market, 3LCD market share is still more than half. In the history, 3LCD advantage than DLP and LCOS projector technology and the age of the big old. Therefore, to discuss the replacement of projector display technology, only 3LCD can afford to be replaced by the glorious role of the role of the. - if LCOS did not work for two years, we can only conclude that the death, but can not enjoy the honor of being eliminated, because he has not really grown up.

In the mainstream market, excellent gene LCOS technology which pose a threat to 3LCD more than one or two: the theory of cost and lower better color, gray higher aperture ratio and light utilization rate, more delicate, more excellent display resolution and contrast, more manufacturers and technical support etc.. But now LCOS is not to be married girl, not really good genes for adult LCOS are genes only, did not become actually "characters". One of the most significant factor is that the LCOS technology theory is the lowest cost, and the reality of the production process of the finished product rate problem is actually the "highest cost". So, if you want to replace or threaten 3LCD LCOS still has a long way to go, at least until the girl "early growth".

At the other end of the 3LCD projection technology is also facing threats from the DLP. Not to mention the most high-end digital movie projector is a DLP exclusive, even if the price of the ordinary mass products DLP market share is only a little less than 3LCD (global market two about 5% of the market share gap, the domestic market of DLP technology but slightly ahead of 3LCD products). However, the current talk about DLP comprehensive elimination of 3LCD is still too early to fashion.

DLP projection technology in ten years, there must be a magic weapon: the price advantage of single DLP projection system. In addition, DLP also has an advantage in the opening rate, contrast, and the richness of industry support. But the monolithic DLP system also has its fatal if the system brings the color wheel and the noise problem just passable. Although these two shortcomings can be solved by using a three chip system, but the high cost of the three slice DLP is absolutely unacceptable market.

With the 3LCD projector compared ". Clearly" decided at this stage of the DLP projection technology does not have the technology of LCD "instead of" absolute advantage. Two in the market competition is still the norm.

However, when the pace of time did not hesitate to move forward in 2008, but it was to break the current DLP and 3LCD technical advantages of the strength of the situation. He is the LED technology known as the future light source. The scientific name is called "electrodeless light emitting diode" LED technology is not only a great boon to improving the performance of the projector light source, but also will be able to become the ultimate technology of light or other light source to replace any existing "role".

LED light source projection frequency, the market is now a new opportunity to change

In 2008, LED projection light source, DLP or LCOS monolithic chip system projection products showed great market potential. In this year, especially in the second half of the launch of the relevant products of the enterprise is not less than ten: this momentum is never in the past.

DELL released a new projector M109S, which is a portable projector DELL launched a pocket projector. The projector using LED light, with 50 open brightness resolution and contrast are 858X600 and 800:1, size is only 9.25cm * 10.5cm * 3.75cm, the weight is only 260 grams, the interface with VGA and composite video interface.

LG released the HS101 upgrade product HS102 projector, using TI's DLP technology, with a standard resolution of 800*600, the use of LED cold light source, with a maximum of 160 lumens brightness, 2000:1 contrast. With 4:3 and 16:9 two output mode selection, support DivX multimedia format, users can directly through the USB interface to play USB Flash movie files, Dolby audio support, the price of 555 dollars, which can support the built-in battery for 2 hours.

NTT DoCoMo produced a mobile phone equipped with projector function. The product is made of the company's existing mobile phones and ultra small projector integrated. The light source of the projector is red, green and blue LED. Equipped with the United States TI (TI) DLP (digital light processing) chipset Pico. DLP Pico by reducing the size of portable products with DMD and its drive LSI. Pixels 480 x 320 pixels HVGA. Brightness of 7.5lm, projector module power consumption is about 3W.

PLUS (Plus) the latest TAXAN projector released in October, TAXAN KG - PL105S projector is the company's smallest projector ever. Its size is 6.1 inches x 2 inch x 4.6 inches (x x wide high), it weighs only 1.7 pounds. KG-PL105S uses SVGA (800 x 600) resolution, 1400:1 contrast, KG-PL105S uses a LED light source, its brightness is 140 lumens. Price of about 9100 yuan. Strong cooling fan noise up to 28-32 db.
