Novel LED driver for multichannel / wide dimming ratio simplified HDTV backlight

To strengthen LED TV in local dimming advantage, innovation LED drive through multiple channels and has a wide dimming ratio independent dimming, to control the light intensity, color and contrast, because it can reach the simplified HDTV backlight design goal, has become the industry new LED driver selection scheme. In order to strengthen LED TV in local dimming advantage, innovation LED drive through multiple channels and has a wide dimming ratio independent dimming, to control the light intensity, color and contrast, because it can reach the simplified HDTV backlight design goal, has become the industry of new LED drive options. With light emitting diode (LED) driver view of the market, currently used to drive white LED driver accounted for about 50% of the white LED is widely used on the back of the display type, with a small portable battery powered lighting products of many hands, but this application has to mature, not in the future 5 years and a very high compound annual growth rate (CAGR). A light emitting diode (LED) driver view of the market, currently used to drive white LED driver accounted for about 50% of the white LED is widely used on the back of the display type, with a small portable battery powered lighting products of many hands, but this application has been relatively mature, not in the next 5 years and is very high the compound annual growth rate (CAGR). LED lighting applications, the growth rate is far greater than the three largest market area on the palm type backlight lighting field interval, one for the car headlights lighting, and large high-definition television (HDTV), the last is the general lighting.

Similarly, 20 mA white LED sales price has been significantly reduced. Similarly, 20 mA white LED sales price has been significantly reduced. Initially launched, the amount of the purchase price of $1. Initially launched, the amount of the purchase price of $1. Today, it is possible to purchase price of less than 20 cents, you can buy a 20 mA white LED. Today, it is possible to purchase price of less than 20 cents, you can buy a 20 mA white LED.

LED TV CCFL TV LED TV to replace CCFL TV as a represent the general trend instead represent the general trend

HDTV for the growth of one of the consumer electronics market is the highest, in the past the large flat screen TV has been using a cold cathode fluorescent lamp (CCFL) backlight. HDTV is one of the largest consumer electronics market growth in the past, large flat-panel TVs have been using cold cathode fluorescent lamp (CCFL) backlight. However, in order to eliminate the toxic mercury vapor in CCFL lighting, while improving efficiency and performance requirements, LED backlight has been pushed into the new HDTV design. However, in order to eliminate the toxic mercury vapor in CCFL lighting, while improving efficiency and performance requirements, LED backlight has been pushed into the new HDTV design. In addition, many governments have adopted new green measures to eliminate toxic materials such as mercury commonly used in CCFL, but also contributed to this trend. In addition, many governments have adopted new green measures to eliminate toxic materials such as mercury commonly used in CCFL, but also contributed to this trend.

As consumers need more HDTV and higher resolution, the television demand has rapidly from high quality plasma (PDP) shift to high-definition LCD TV (LCD TV). As consumers demand greater HDTV and higher resolution, the demand for televisions has rapidly shifted from high quality plasma (PDP) to High Definition LCD TV (LCD TV). According to market research company, high quality PDP sales peaked in 2008, revenue of about $24 billion, while high-definition LCD TV has a $75 billion market value to 2010 will grow to $93 billion. According to market research company, high quality PDP sales peaked in 2008, revenue of about $24 billion, while high-definition LCD TV has a $75 billion market value to 2010 will grow to $93 billion. However, there are still many shortcomings of high-definition LCD TV, including fast motion blurred images from the color reproduction is not accurate. However, there are still many shortcomings of high-definition LCD TV, including fast motion blurred images from the color reproduction is not accurate. As far as HDTV is concerned, it is not possible to achieve true black, and the dynamic range of all colors has room for improvement, such as high-definition LCD TV
