Light emitting diode (LED)
It can be seen everywhere in our daily life and is extremely common and well known.
LED has the characteristics of high efficiency, good light quality, power saving, long service life, etc. It is mainly used in downstream application product markets such as plane display field, portable equipment display, lighting and infrared LED field.
Compared with the traditional light source, LED light source is small in size, light in weight, good in directivity and can withstand various harsh conditions, and has incomparable advantages in power consumption, service life and environmental protection, enough to have a major impact on the traditional light source market.
With the increasing application scope of LED, more and more attention has been paid to the importance of LED.
A ColorYourLife seminar held near Taiwan has conducted extensive discussions on various possible applications of LED.
Zhuang Shiren, director of the research and development department of Yiguang Electronics, a major LED manufacturer in Taiwan, pointed out in his speech that the full-color LED light source LCD screen of mobile phones, which is indispensable in daily life, the LED outdoor full-color super-large display screen set up in the World Cup venue has changed the visual experience of modern human life.
Therefore, our vision has the angle of observing things in full color. With the improvement of photoelectric semiconductor LED technology, our quality of life will enter a new era of truer and more beautiful.
Zhuang Shiren's words pointed out the wide application of LED, and also pointed out the business opportunities of LED.
LED is composed of semiconductor materials and is a luminous component that emits photons of different spectral frequencies by combining electrons and holes in semiconductors.
The application field of LED in the early stage was limited to the indication application of monochromatic light, but in recent years, with the improvement of monomer brightness and luminous efficiency of full-color LED, its application field has shown a trend of gradual expansion.
In particular, the development trend of LED in lighting applications has attracted more attention.
Zhuang Shiren pointed out that because traditional fluorescent lighting lamps contain heavy metals such as mercury, LED has the advantages of power saving, long service life and environmental protection under the increasing awareness of environmental protection, it is bound to make it an ideal choice to replace the current lighting fixtures.
Although the luminous efficiency of LED cannot exceed that of ordinary fluorescent lamps at present, White LED applied in special lighting market still has considerable potential, such as solar LED lamps, portable lighting sources, etc.
Furthermore, with the improvement of chip efficiency and fluorescent powder technology, it is predicted that LED will gradually develop from the application of local lighting to the general space lighting market in the next few years.
Zhuang Shiren even took the Shanghai Oriental Pearl TV Tower as an example to illustrate. He pointed out that the luminous point on the facade of the Shanghai Oriental Pearl TV Tower was originally a traditional light source, and the power of a luminous point was 200 watts.
The brightness of traditional light sources will gradually weaken.
Therefore, since the early 2005 s, the TV tower has replaced the original light source with LED.
Compared with the original light source, the front luminous area of the LED is expanded by five times, the luminous efficiency is also increased by five times, and the power of a luminous point is only 50 watts, it can save nearly 160 thousand degrees of electricity a year.
On the whole, LED has three primary colors of red, blue and green, which can be mixed into various colors. Compared with the four-color light of the original traditional light source, it is easier to show the combination of full-color patterns and characters.
Furthermore, the photoelectric semiconductor LED light source technology developed by human beings in the process of developing high-quality light sources has quickly cut into various aspects of life applications, even biomedicine, from different angles.
For example, capsule endoscope is one of the applications.
In general, endoscopy cannot perform a complete examination of the small intestine, so capsule endoscopes equipped with LED light sources and cameras are required when more precise diagnosis is needed.
The application of LED is not far away, and other business opportunities such as the application of household electrical appliances and automobile products are even more expected, not to mention the application of panel backlight.
Although the notebook computer panel backlight application originally expected to erupt in the second half of the year is slightly delayed, the market growth of LED in panel backlight application in the next three years is unquestionable. At this stage, LED is at 3.
The penetration rate of small-sized panel backlights below 5 inch has reached 100. This year, LED backlights are rapidly fermenting in the 7 inch panel market, with an estimated LED share of about this year.
In the second half of the year, the application of LED backlights in notebook computer panels increased. In addition to Japanese manufacturers, Taiwanese notebook computer manufacturers such as Quanta, Compal, Asus, etc. will launch LED backlit laptops.
It is estimated that the penetration rate of LED backlights in notebook computer displays between 11 inch and 13 inch will increase from 3 this year to 8 next year.
On the price level, LED applications have increased and prices have continued to decline.
Overall, the average price of mobile phone button products has fallen by 50 this year, coupled with the slowdown in the growth of the mobile phone market, resulting in a decline in revenue contribution.
While products such as panel backlighting are in short supply, the unit price has also dropped by 20% under the strong leadership of downstream manufacturers.
However, the industry generally believes that although the LED unit price has dropped rapidly, other applications such as digital cameras, MP3 players and other portable products have increased, and it is estimated that the LED output value will continue to grow this year.
According to the statistics of IEK of Taiwan Industrial Research Institute, the market size of light emitting diodes reached 57. 5% in 2005.
0. 3 billion US dollars, a slight increase of 6. From 2004.
Due to the rapid expansion of Asian LED manufacturers in recent years, the supply and demand are out of balance.
However, according to IEK's observation, the expansion plan of emerging Asian countries will slow down in 2006, which will balance supply and demand. Therefore, it is predicted that the market size of light emitting diodes in 2006 will grow by 8 to 62 compared with 2005. $0. 3 billion.
