According to Strategies Unlimited’s research in 2010, high-brightness LED market is expected to reach $ 8.2 billion, and 2015, is expected to grow to 202 billion U.S. dollars, the annual compound growth rate (CAGR) of 30.6%. Currently used to screen for the LED backlight is the main driver of this growth factor, its applications include high-definition TV, car display, a large number of handheld devices. To maintain high growth rates, LED not only need to provide higher reliability, lower power consumption and smaller / more flat dimensions, but need to improve the contrast, sharpness and color quality accuracy. In addition, automotive, avionics, and marine displays but also for a variety of ambient lighting conditions, such as bright sunlight, dark night and so on. These transistor liquid crystal display (TFT-LCD) is widely used, from the infotainment system, a variety of meter to meter, with LED backlight on the display when these, in order to include a wide variety of ambient lighting conditions to optimize the display legibility, will bring some unique design challenges of LED IC drivers, which requires drivers to provide LED dimming range is very wide and high efficiency, and to withstand the relatively harsh and harsh environment of automotive electrical and physical test. Finally, these solutions must be flat and compact footprint, in order to improve cost-effectiveness. [Read the rest of this entry...]
