It may be difficult to imagine today that the luminous flux of LEDs was only one-hundredth of a million years ago. The previous equipment could not handle the current material technology. Only 20 years ago, LED applications began to move from indoors to outdoors, but still use red LEDs. Mainly, the brightness of the blue LED is still insufficient.
However, the real big breakthrough in LED R&D was 15 years ago. In 1993, the Japan Photographic Association expressed its opinion that blue LEDs could not be used outdoors in a short period of time, and it is estimated that in 2000, there will be an opportunity to improve performance by 100 times. At the application level, in November 1993, Nichia Chemical developed the high-brightness blue and green LEDs using MOCVD epitaxial technology, making LED technology officially into the era of full color. The results of the Japanese-Asianization were only a few months away from the publication of the Japan Photo Association. It can be seen that the degree of Nichia's research and development is confidential, and it is even more surprising that other labs have repeatedly repeated the blue LED technology. Can't do it.
Prior to the publication of the results of Nichia, ITRI was also discussing the process of LED materials. In 1993, a forward-looking meeting was held. The theme was what materials should be used for blue LEDs? At that time, two opinions were formed in the meeting, because materials and platforms were the key points that must be chosen. One group believed that MOCVD should be adopted, which is the same as the technical platform of the later Japaneseization, while the other group believed that MBE should be adopted, but at that time No conclusions, no more, this drag, so that ITRI did not urgently allocate funds to the research of blue LED until 1995, no decision-making, and can only deal with the results of other people's changes.
In the past 30 years, the LED industry has undergone major changes in technology or product applications, impacting on old materials and processes. Until now, although LEDs have begun to enter new applications such as lighting and TV backlights, they have been chasing afterwards. Bing, there are other technologies such as OLED, which may be replaced, so change and innovation is the road that the LED industry must continue to go on!
LED backlight applications are gradually becoming a trend, but large-size TV LED backlight products are still in their infancy. If LEDs cannot quickly improve luminous efficiency and reduce costs, it is likely to be replaced by OLEDs in a few years; LED lighting is environmentally friendly. The advantages of energy saving, but if the price can not be drastically reduced by 10 times, and the energy saving effect of current energy-saving light bulbs is only a short distance, so in the next 10 years, the popularity of LED applications should consider the speed of cost reduction, which will be the challenge facing the LED industry. .
But this goal is not impossible. The change needs to break away from the framework of thinking. The LED industry should be placed in the perspective of globalization. For example, international companies such as Europe and the United States can focus on technological breakthroughs and increase the luminous efficiency of LEDs to 150lm/w. The level of Taiwan, while playing the role of cost reduction, because only the improvement of luminous efficiency, current volume and cost reduction, LED can enter the general lighting market can be realized, the impact will not only benefit a single company, but all humans and The goal of environmental conservation.
