LED has many advantages such as low volume, low power consumption and long life. With the small-size LED backlight, the penetration rate of mobile phones and consumer electronic products is approaching 100%. The LED backlight application category begins to be in the car, external light source, medium and large size LED backlight. Development, and even replace the traditional lighting source with LED lamps with environmental protection and energy saving concept, the application range continues to extend.
With the continuous application of LED applications, the types of terminal products are also diversified. According to the properties of LED light source terminals, the LED application market can be roughly divided into automotive, communication, information, consumer electronics, industrial, lighting, etc. 5 The large category, based on the difference in the position and penetration ratio of the individual application market, the corresponding LED driver IC application market outlook is completely different.
Looking forward to 2010, as the global economy gradually recovers, the LED driver IC market for automotive and communication in 2009 will be expected to stabilize. The industrial and lighting markets also have a 2-digit growth space for information and consumer electronics. With the market, there will be leap-forward growth. It is estimated that the global LED driver IC market will expand to 3.41 billion in 2010, compared with 2.70 billion in 2009, with a growth rate of 26.0%.
With the increasing acceptance of the market, LED backlights have also begun to develop towards large-scale applications such as LCDTVs and LCD monitors. If viewed on a market scale, the LCD driver IC market for LCDTV will be the first in the market, while the NB and LCD monitor applications will follow in order. If observed by the growth rate, the LCD driver IC market will grow at a higher rate. In order, it is applied to LCDTV and NB.
Based on LED backlight, LED lighting, LED lighting related applications, Constant Current technology to achieve consistent brightness, Pulse Width Modulation (PWM) integration technology with integrated brightness adjustment (Brightness Dimming) function, The high voltage technology of LED indoor lighting and the high current technology of ultra high brightness LED lamps will be an important development trend of future technologies of LED driver ICs.
