From PHILPS to invest at high brightness LED development prospects

Lighting market is a long-term development direction. Many people are optimistic about the future of LED in the lighting market opportunities, as in Taiwan, Japan, forecast related units manufacturers, if LED can replace general lighting, can build several nuclear power plants. But because the price is far lower than the general lighting lamp LED lamp, it is estimated that American families around the lighting should be more than $12 thousand by LED, so full replacement may at least have a chance after 2030, the short term LED is used in lighting are still biased in favor of decorative lighting and special occasions such as surgical lamp etc.. Because commercial lighting LED the service life of the general requirements in 50 thousand hours, as if the traffic sign theory 3~4 years does not need to be replaced, so save labor costs and avoid delays from the traffic point of view, the future application of LED in traffic signs will be gradually popularized.

In the future LED TV market development has been looking forward to, because of the use of LED as a backlight LCDTV, the color reproducibility (ColorReproduction) can easily reach NTSC specifications more than 100% level, but the CCFL lamp in general, most can only provide a level of 72%, so LCDTV is not in the ornamental quality can be far beyond the other display where is the key of LED backlight. SONY in the fourth quarter of 2004 about the commercialization of QUALIALCDTV as an example, the 46 inch products using LED backlight, which is the use of Lumileds products, the products need to use more than 400 groups of LED (R, G, each containing B), so the LCDTV price of more than $10 thousand, belong to the most high-end LCDTV. Although the sales volume is limited, but it is the indispensable commodity flagship SONY display LCDTV technology and brand image.

Samsung Electronics (SamsungElectronics) seven generation line production of 46 inch LCD, part of the high file products in the future will be the same as the SONY QUALIALCDTV, using LED as backlight. According to the LCD leader in product development blueprint and technology forecast, the past 2002~2004 years LCDTV is entering the market stage, so try to improve the viewing angle is too narrow, low contrast, slow response and cause consumers to discuss is the main topic, the problem has been resolved and generally reach the commercial standard. Now many people buy LCDTV not because digital TV trend or is the image to catch up with CRTTV, but LCDTV in the price for a few years after a sharp decline, with light quality performance thin appearance and to a certain extent, has been enough to attract consumers early (about 10% 5~ overall consumer purchase).

Expected in the 2005~2008 stage, will be LCDTV and PDPTV two thin TV in the competition in the cost of the war, both sides believe that there are a lot of the decline in the cost of space, so who can drop faster, will be the size boundary and quality difference gradually under fuzzy winning key. In addition, estimation of the backlight module manufacturers, in 2008 to LED backlight backlight module of large size the size of the market will grow to $160 million, compared with $2 million in 2005 to grow 80 times, we can see the growth of this market potential.

If after 2008 LCDTV win, LCDTV itself will face technical challenges, the use of LED backlight LCDTV, and the plane light source and the further development of the traditional CCFL (FFL) will launch a new confrontation, 2012~2015 estimated to be FPDTV LCDTV OLEDTV challenges the mainstream is still a threat. However, emerging display technology emerging, the future of FED technology is also trying to grab one of the threats to the TV market. In short, the application of mobile phone, car and LCD backlight is the points of development stage LED, the long term is the permanent direction of LED lighting applications, LED has been selected as one of the 100 great inventions of mankind in twentieth Century, whether the reform in twenty-first Century, believe that PHILPS is not only, but also involves a revolution of tens of thousands of people daily life the.
