LED application field continues to expand market size
Light-emitting diodes (LEDs) are everywhere in our daily lives and are very common and well known. LED has the characteristics of high efficiency, good light quality, power saving, long life, etc. It is mainly used in the downstream application products such as flat display field, portable device display, lighting and infrared LED field. Compared with traditional light sources, LED light source is small in size, light in weight, good in directionality and resistant to various harsh conditions. It has incomparable advantages in power consumption, life and environmental protection, which is enough to cause significant impact on the traditional light source market. Shock. With the increasing range of LED applications, the importance of LEDs has received more and more attention. A recent ColorYourLife seminar in Taiwan has extensively explored various possible applications for LEDs. Zhuang Shiren, Director of R&D Department of Everlight Electronics, a major LED manufacturer in Taiwan, pointed out in his speech that from the indispensable mobile phone full-color LED light source LCD screen in daily life, to the LED outdoor full-color super large display screen set up in the World Cup soccer venue. The application of LEDs has changed the visual experience in modern human life. Our vision thus has a full-color view of things. With the advancement of optoelectronic semiconductor LED technology, our quality of life will move into a new era of more true and beautiful. Zhuang Shiren's words point to the wide range of LED applications, but also point out the business opportunities of LED. The LED is composed of a semiconductor material and is a light-emitting component that utilizes electrons and holes in a semiconductor to emit photons of different spectral frequencies. Early LED applications were limited to the use of monochromatic light, but in recent years, with the increase in the brightness and luminous efficiency of full-color LEDs, the field of application has gradually expanded. In particular, the development trend of LED in lighting applications is even more noticeable. Zhuang Shiren pointed out that because traditional fluorescent lighting fixtures contain heavy metals such as mercury, LEDs have the advantages of power saving, long life and environmental protection, which is an ideal choice to replace current lighting fixtures. Although the luminous efficiency of LEDs can't exceed the general fluorescent lamps, the white LEDs used in the special lighting market still have considerable potential, such as solar LED lamps and portable lighting sources. Furthermore, with the improvement of chip efficiency and the improvement of phosphor powder technology, it is predicted that LEDs will gradually develop from the application of local lighting to the market of general space lighting in the next few years. Zhuang Shiren also cited the Shanghai Oriental Pearl TV Tower as an example. He pointed out that the luminous point of the facade of the Shanghai Oriental Pearl TV Tower was originally a traditional light source, and the power of one luminous point was 200 watts. The brightness of the traditional light source will gradually decrease. So since the beginning of 2005, the TV tower has replaced the original light source with LED. Compared with the original light source, the front light-emitting area of ​​the LED is increased by five times, the luminous efficiency is also increased by five times, and the power of one light-emitting point is only 50 watts, and the power of nearly 160,000 degrees can be saved in one year. Overall, since LEDs have red, blue, and green primary colors, they can be mixed into various colors, which is easier to express the combination of full-color patterns and text than the four-color light of the original light source. Furthermore, the optoelectronic semiconductor LED light source technology developed by humans in the process of developing high-quality light sources has been rapidly cut into various aspects of life applications from different angles, even biomedicine. For example, a capsule endoscope is one of the applications. In general, the endoscope cannot perform a complete examination of the small intestine portion, so a capsule endoscope equipped with an LED light source and a camera is required in the case where a more precise diagnosis is required. The application of LEDs is far-reaching, and other business opportunities such as those in home appliances and automotive products are even more exciting, not to mention the application of panel backlights. Although the notebook panel backlight application that was originally expected to break out in the second half of the year is slightly deferred, the market growth of LED backlight applications in the next three years is unquestionable. At present, the penetration rate of LEDs with small-sized panel backlights under 3.5 inches has reached 100. This year, LED backlights are rapidly fermented in the seven-inch panel market. It is estimated that the LED market share will be about 30. The LED backlights in the second half of the year are in the notebook panel. The application has increased, in addition to Japanese manufacturers, Taiwan's notebook computer manufacturers such as Quanta, Compal, Asus, etc. will launch LED-backlit notebook computers. It is expected that the penetration rate of LED backlights on 11-inch to 13-inch notebook screens will grow from 3 this year to 8. Next year, on the price level, LED applications will increase and prices will continue to decline. Overall, the average price of mobile phone buttons has fallen by 50 this year, and the slowdown in the growth of the mobile phone market has contributed to the decline in revenue contribution. While the high-end products such as panel backlights are in short supply, the unit price has also fallen by 20% under the strong leadership of downstream manufacturers. However, the industry generally believes that although LED unit prices fall rapidly, other applications such as digital cameras, MP3 players and other portable products. Under the increase of application, it is estimated that LED output value will continue to grow this year. According to the statistics of the IEK of the Taiwan Industrial Technology Research Institute, the global LED market reached 5.73 billion U.S. dollars in 2005, a slight increase from 2004. In recent years, the expansion of Asian LED manufacturers has been too fast, making supply and demand unbalanced. However, according to IEK's observations by the ITRI, the expansion plans for emerging countries in Asia will slow down in 2006, which will balance supply and demand. Therefore, the global LED market in 2006 is forecast to grow by 8 to US$6.23 billion in 2005.
