LED backlight popular drive IC market volume

With LED applications more widely, the LED driver IC market is "light shining". According to China's Taiwan Research Institute IEK data show that the LED driver IC market value will increase from $900 million in 2008 to $2 billion 900 million in 2013, a compound annual growth rate of 26.4%.

LED backlight market as the main driving force

Before LED driver IC is the largest market for application in the mobile phone on 2010, but due to the LED backlight LCD TV boom, used in backlight LED driver IC has become one of the fastest growing application market. At the same time, LEDNB, LED indoor lighting, LED street lights, LED outdoor display will have explosive growth, the rapid growth of the LED application market for LED driven IC has created a huge market. The topology Research Institute research shows that in 2009 the LEDNB penetration rate of 60%, 2010 jumped to 95%, become an important force in the LED industry growth. It is worth noting that, with the penetration of LEDNB will reach 100% in 2011, the focus of the market will turn to LED backlight TV module market.

LED backlight LED driver IC market has become the strong growth of the "fulcrum" and LED lighting will become the third wave". According to TRI statistics, in the development of LED industry, 2010 -2012 large LED backlight will reach the peak of growth, LED lighting is in its infancy; 2013 -2015 large LED backlight will reach maturity, LED lighting will be in a high growth period; 2012-2015 LED entered the peak period.

LED to inject fresh impetus the development of the industry, China's LED driver IC market continues to improve. According to iSuppli expects China's LED drive IC market size reached $127 million 700 thousand in 2013, will reach $139 million in 2010, with a compound annual growth rate of 4.4%.

Driver IC is not a requirement

The application of corresponding to different LED driver IC, there are three basic categories, one is the battery for low voltage and low current LED drive energy, mainly for consumer electronics products, the general demand for 1 to 3; two is the battery energy requires high voltage step-down LED drive IC, mainly used in automotive lighting products, voltage is 48V; three is used for lighting and LED TV etc. large size panel backlight, AC needs to be directly converted into DC LED driver IC. Large size of the general demand for dozens of dozens of stars to drive IC, and the number of LED lighting required to drive the IC depending on the power of the family lighting is generally 1 ~ 2.

Along with the rapid development of LED applications, rely on the quality of LED drive power supply is also rising, so the driving efficiency and the reliability of the power supply itself becomes critical. Wuxi Crystal Technology Co., Ltd. chairman Huang Wei introduction, to meet the above requirements, LED material, the impact of technology is relatively large, this area should be resolved.

Huang Wei also introduced, LED lighting is the most important part of the LED light source and power supply, power supply, transformer and IC including driving resistance, long service life and reliability of the LED light source is not high, but the performance is not stable, the transformer life is less than that of the LED light source. LED lighting performance and design, in ensuring the performance of the premise, the peripheral device is the less the better. General LED lighting required for each voltage is about 3V, while driving the IC output voltage of 60V, when the current is 350mA, can be connected in series 20 lamps; when the current is 700mA, can be parallel to each of the two lights.

And LED TV on the light source of higher quality requirements on the quality and quantity requirements of driving IC is higher. LED backlight module has two main design schemes: one is Direct (straight line), and the other is Edge (side light type).

Side light type LED backlight TV General specifications for 3 ~ 5 LED light string as a group, each LED TV size specifications 4 ~ 6 groups in the overall cost control and quality specifications, the backlight side light type assembly is better.

, OEM manufacturers should padded short board

LED driver IC is currently in the domestic market competitors in addition to veteran foreign enterprises, the backbone of the Chinese enterprises in Taiwan, and China, the bright younger generation. Foreign companies such as TI, ADI, NS, linear, Fairchild, A Morimi, Maxim and NXP, a relatively complete series of products, occupy the mainstream in the market. Dianjing, crystal accumulation, research in Taiwan manufacturers are relatively active, notebook computer is one of the most competitive market. While Chinese mainland enterprises include integrated device manufacturers (IDM) such as Shanghai, Hangzhou belling Silan powtech, Huarun and so on, in addition, there are dozens of IC design companies in the development, but the production scale is small, the application is not too wide, IC vendors in this market will accelerate the padded short board foundry fengeng.

"Because of high voltage LED driver IC dependence on technology, China, in high voltage IC foundry is also less, but technology is not too mature. "Huang Wei said," the technology LED driver IC complex, professional and strong, the mainland manufacturers in the LED driver IC market make a difference, the most important is to solve the bottleneck of the process, must have own foundry process line, to take control of the process.
