LED driven IC demand increases, Taiwan manufacturers active action

As people continue to pay attention to environmental protection, energy saving characteristics of LED has been paid more and more attention, and therefore drive the opportunity of LED driven IC. The IC design industry in Taiwan throughout the number of input LED driving field of IC peaked in 2008, especially the simulation of the IC industry has the technology advantage, almost all have been driving the layout of LED IC field, and the industry estimated LED market in 2008 and 2009 years will be the breakthrough growth is the relationship between. Overall, the current LED driver IC lock market can be divided into high and low-end market, the three level, which is mainly in the high-end large LCD panel backlight, automobile lighting; in the end mobile phone backlight, indoor lighting, traffic signs, billboards, GPS and other portable white light products; low-end part includes landscape lighting, portable lighting and light shows etc.. Notebook computer is one of the most important battlefield in the area of LED driver IC industry in Taiwan.

NetBook LED backlight penetration of nearly one hundred, indoor lighting prospects can be expected

Research Report of Morgan Stanley pointed out, LED in the NetBook backlight penetration will reach 95% in 2009, in 2010 it will reach 100%, and for the 45 million NetBook LED driver IC shipments will be by the year of 21 million to 2012, priced from $0.35 in 2009 to $0.26 in 2012. From 2009 to 2012 the compound growth rate of 21%. As for the general notebook computer in LED backlight has more than ten percentage points from last year to 32% this year, and then will be a way to grow, in 2010 55%, 2011 70%, 2012 reached 90%, driven IC in the compound growth rate of 39% for 2009~2012 years.

It is also worth noting that in the indoor lighting, LED driven IC shipments this year's forecast for 34 million, to 2012 will be increased to 125 million, the compound growth rate of 39%, is also potential market for LED driver IC industry can not be ignored.

On the design of the IC industry in Taiwan, the investment situation, the current lock in the field of mobile phone LED backlight, LED backlight, etc., in addition to the layout of the interior has also been in the field of lighting. However, due to the LED drive technology still has a certain threshold, so the starting speed difference large suppliers.

On the whole, the characteristic requirement of LED driver IC is the consistency and constancy of current output. LED driver IC need to control one or more pieces of LED, LED and brightness by electrical flow linearly proportional relationship, so to make LED emit the same brightness, the amount of current LED must keep consistent together, and this is the LED driver, IC quality is bad. Furthermore, the LED itself is still possible because of the temperature or the use of time and other issues resulting in reduced efficiency, the driver must be designed to effectively detect the LED IC internal error mechanism. These features can be seen from the characteristics of the LED driven IC products of metallocene electronics.

It is understood that since the beginning of 2007 Maoda into the LED driver IC, the initial focus on GPS mobile phone and portable device, and cut the notebook computer market since last year, has begun to enter the indoor lighting, the other in the fourth quarter of this year the bottom will enter the billboard market.

ANPEC Electronics Marketing Department deputy director Gu Qiongjing introduced the company's white LED driver IC pointed out that the product has the advantages of small volume, low calorific value, low power consumption, long service life, fast response, environmental protection and plane package etc.. Overall, the LED product line is characterized by a complete product line, including AC-DC to DC-DC, mobile phones, laptops and indoor lighting, etc., can provide complete protection.

LED outdoor billboard business opportunities

When it comes to outdoor LED panel market can not ignore the accumulation of science and technology, one of the leading manufacturers of the company driver IC for LED in Taiwan, the main application is the outdoor billboards, this part of the company's overall revenue accounted for more than 90%, and in 2008 the global market share of 47%, the company's other products include LED backlight and lighting etc.. Accumulation is able to achieve good results in the outdoor billboards, mainly because of the development and management of power supply and the power supply circuit of the company's conversion technology, such as the development of the S-PWM patent technology can increase the overall visual refresh rate, reduce flicker phenomenon.

It is estimated that in 2009 LED large outdoor advertising market value will increase to $8 billion in 2010, held in Shanghai, World Expo will also for outdoor application of LED waves, coupled with the recent governments have launched major projects such as the expansion of domestic demand, so this year is expected to outdoor billboard LED drive IC will continue to grow. In addition to outdoor billboards, the accumulation is also actively into the LED lighting and backlight market.

Integrated product reduction system to reduce costs

The notebook computer is almost in Taiwan LED driver IC industry's military a hotly contested spot. The director of the business simulation technology company Zhu Xiaowei said the company does not push independent LED driver IC products, but the main integrated solutions, combined with the power management and LED driver IC, the main lock notebook computer LED backlight module market, is expected in the second half will start large shipments. He believes that compared to stand-alone LED driver IC, integrated solutions can provide benefits include simple design, low cost.

In addition to notebook panel backlight module, analog technology companies are also quite optimistic about the LED lighting market, is expected to launch the corresponding product at the end of the second quarter. However, at this stage, due to the LED indoor lighting market is still limited, it will still be assisted lighting applications. In addition, although the LED backlight in LCD TV penetration is still very low, but the company is currently working with some LCD TV manufacturers to integrate
