EPISTAR chairman Li Bingjie: do not dare not to talk about the change of decision

Change is the need to make decisions! Now the biggest problem in Taiwan society is what want to do, but it is not the practice of making decisions, South Korea and Taiwan are different, they may use 4 years to spend 1 billion yuan to invest in R & D, if achievements do not give up, but Taiwan could be spent 10 years with 400 million yuan to try every way to try to and expects to receive a recovery, but whether business or industrial development, not what should be, must use the limited resources to make a choice.

It may be hard to imagine, luminous flux of LED 30 years ago only 1/100 now, before the equipment has been unable to handle the material technology, 20 years ago LED began from indoor to outdoor, but still red LED, blue LED brightness is still insufficient.

But the real breakthrough in LED research is in 15 years ago, in 1993 the Japanese Association of portrait views, pointed out that the blue LED in a short period of time, fear can not be used in outdoor, and have the opportunity to enhance the forecast in 2000 100 times performance, and achieve the application level, but in November 1993, Nichia MOCVD using science technology to develop epitaxy high brightness blue and green LED, so LED technology officially entered the era of full color. The results from the published Nichia Photographic Society of Japan is still only a few months, visible Nichia R & D confidential home level, more surprisingly, even when other laboratory repeated Nichia blue LED technology to do.

Before Nichia published results are also discussed, ITRI LED material process, will be held in 1993 the theme is prospective, blue LED should be made of what material? At that time will be formed in the two views, because the materials and platforms are key must be a choice, that should be sent by MOCVD, and then it also Nichia technology platform, and another to take MBE, but there was no conclusion, this study makes a settle a matter by leaving it unsettled, ITRI, until 1995 the emergency investment funds of blue LED, don't make decisions, always can only deal with the change results from others.

In the past 30 years, the LED industry either in technology or product applications have undergone significant changes, the impact of the old material and process until now, although LED began in the new lighting applications and TV backlight, but after the pursuers, there are other techniques such as OLED, may instead. Therefore, the reform and innovation of LED industry must always go on the road!

LED backlight applications has become a trend, but the large size of the TV LED backlight products is still in its infancy, if LED is unable to rapidly improve the luminous efficiency and reduce the cost, in a few years, will be replaced by OLED; LED lighting has environmental advantages of energy saving, but if prices fell sharply to 10 times, and the energy saving the effectiveness of energy-saving bulb is not far away, so the next 10 years, the popularity of LED applications must consider the cost rate of decline, it will be LED the challenges facing the industry.

But this is not impossible, to change out of thinking framework, LED industry should be placed in the global view, such as Europe and the United States and other international manufacturers can focus on technological breakthroughs, will enhance the luminous efficiency of LED to the level of 150lm/w, while Taiwan is playing role to reduce the cost, because only the luminous efficiency, the amount of current increase and decrease the cost at the same time to reach LED, enter the general lighting market can be realized, it will influence not only for the benefit of a single company, but for all human beings and the environment and conservation goals.
