High pixel mobile phone to send Biao LED flash bullish demand

Thin, high pixel camera mobile phone trend, LED flash will spur a surge in demand, in order to seize the market opportunities, this year will launch the LED supplier of higher brightness, higher driving current products; LED driver IC vendors are competing: small size, high efficiency white LED current and high conversion drive IC program.

This year, the world's top five mobile phone manufacturers such as Motorola, Sony Ericsson and NOKIA are invariably overweight launched high pixel camera and eight million pixel camera mobile phone, mobile phone is either hot on the occasion, the April SHARP wins while chasing, released the industry's first ten million pixel camera mobile phone, for the industry to cast a heavy bomb, the concern is in addition, Sony Ericsson has always maintained the traditional xenon lamp, Motorola, NOKIA, SHARP, Le Jin (LG) and other mobile phone suppliers has launched a light emitting diode (LED) flash photography hand machine.

With the mobile phone manufacturers have launched a high pixel camera phone, coupled with the appearance of thin trend, so LED flash widely favored by mobile phone manufacturers. In addition, compared to the traditional xenon flash, LED flash still has the ability to save energy, fast charging and lighting for a long time, so it can support the use of mobile video lighting light source, the potential development of the potential. In view of this, to attack LED flash photography mobile phone market opportunities, LED components and LED driver IC manufacturers also have launched layout.

PHILPS Lumileds overweight LED Flash Market

LED flash has PHILPS Lumileds's main product line, after the potential, optimistic about the LED flash before the PHILPS Lumileds code introduced a new generation of LUXEON Flash series of LED products, more emphasis on high brightness and high driving current, is expected to be officially mass production before the end of this year.

PHILPS Lumileds lighting product manager MichEL Zwanenburg said that tens of millions of pixels camera mobile phone has been the company's latest represent the general trend, and published LUXEON Flash series LED drive current can reach 1 amp market requirements, and the maximum drive current can be as high as 2.5 amperes.

With thin and million pixel camera mobile phone is popular, with more high brightness LED flash is imperative, therefore, South Korea mobile phone manufacturers have launched LED mobile phone brewing flash photography 1000 Ma drive current, the design of LED flash will face more stringent challenges in the future, in addition to using high brightness and high driving current of LED, Zwanenburg that, at 1000 Ma drive current LED flash scheme, power conversion efficiency and power management for two key design.

In addition, Zwanenburg analysis, the future of high power LED to achieve the purpose of heat dissipation will require greater cooling area, therefore, LED will flash toward the development of large size, but also to take into account the market for LED light source color accuracy and consistency requirements.

Not only is the LED manufacturer, aimed at the new rise of LED flash camera mobile phone market opportunities, LED driver IC vendors have long been ready, ready to take off.

Camera mobile phone business opportunities appear to drive IC manufacturers to do

STMicroelectronics analog / power and MEMS components product marketing manager Yu Zhengde believes that white LED flash will be more opportunities than RGBLED flash into the mainstream.

Thin million pixel camera, mobile phone is becoming the trend, driven by the rising market demand IC LED flash drive, and a keen sense of smell LED driver IC manufacturers have launched the first small size, high efficiency white LED current and high conversion driver IC, in order to seize market opportunities.

Compared to the traditional xenon lamp, LED flash energy saving, thin advantages, so that it replaced the xenon lamp as the main mobile phone camera program is increasing. STMicroelectronics (ST) analog / power MEMS components and product marketing manager Yu Zheng stressed that although the brightness is still far higher than the LED xenon flash flash, but the power conversion efficiency of defects, has been unable to meet the mobile phone manufacturers to the stringent requirements of battery life. In contrast, the rapid progress in the promotion of LED lighting brightness, but also both energy saving and miniaturization characteristics, the future has the opportunity to stand out.

In addition to the characteristics of the component itself better, LED flash is also a lot of simple design. The traditional xenon flash insulated gate bipolar transistor with high voltage switch component (IGPT), in printed circuit board (PCB) produces high pressure, so the designer must take many insulation measures, lead to the design complexity is increased; in contrast, LED is the highest operating voltage of only 4 volts, a low voltage drive, can greatly simplify the design difficulty.

In view of lightweight, high pixel mobile phone camera has to represent the general trend, including STMicroelectronics, National Semiconductor (NS), Adno (ADI) and A Morimi (ON Semiconductor) and other power chip makers have to launch with a small size, high current characteristics of LED flash drive IC program. Among them, STMicroelectronics scheme using thin fine pitch ball grid array (TFBGA) package, in June this year. Anson's first use of micro quad flat no pin (QFN) 3.5 mm x 3.5 mm x 0.55 mm, 10 ampere capacitor LED flash drive IC; July National Semiconductor (NS) and Adno (ADI) launched by the micro surface mount component (Micro SMD) is less than 23 mm x 23 mm, 1.2 amp and 12-ball wafer level chip size package development package (WLSCP), 500 mA LED IC flash drive.

In addition, in order to achieve the purpose of adjusting the brightness, the current LED driver IC suppliers are in the LED flash drive IC built-in internal integrated circuit (I2C) interface. Experts say today
