LED out of the back of the screen to drive the IC mobile phone applications

Because of the efficiency and the overall LED light output increasing, lighting will exceed the mobile phone this year, become the LED driver integrated circuit (IC) of the largest application areas, its operating income from 2012 will grow by more than 50%, five years more than doubled.

According to a report by IHS's IMS Research, this year's LED drive IC market for LED lighting will grow from $214 million in 2012 to $323 million, exceeding the mobile LED drive IC market. This year's mobile phone LED driver IC revenue is expected to be $316 million. The next few years, the overall LED driver IC industry revenue will continue to grow, is expected to reach $519 million in 2015, rose to $666 million in 2018, is expected to reach $810 million in 2014, as shown in figure.

At the same time, this year's mobile phone LED drive IC shipments will continue to be high, is expected to be 1 billion 500 million, while the LED lighting field shipments of 1 billion 100 million. However, in 2014 the field of lighting shipments will exceed the phone, it is expected to reach 1 billion 900 million, while the mobile phone is a field of 1 billion 700 million.

Over the years, the LED backlight is more widely used than lighting purposes, mainly used to illuminate the display, rather than illuminate a variety of places. But LED is now out of the back of the screen, is increasingly used for home and corporate lighting. When a large number of LED used in a light bulb, compared with fluorescent lamps can save a lot of energy.

LED lighting applications include flashlights, streetlights, residential or office lights, as well as retail or commercial establishments such as hotels. With the improvement of its efficiency and overall light output, LED lamp is more and more attractive. In particular, the cost of maintenance may become a problem, such as supermarket refrigerator lights or factory and warehouse high ceiling.
