The Need of LED Backlight Technology

Seven Advantages of LED Backlight Technology

The technology of led backlight has become the mainstream, and led backlight is recognized for its no mercury, low energy consumption, excellent color and long working life. Firstly, the expressive force of backlight color is stronger than CCFL backlight, which can make up the lacking of display color for liquid-crystal technology. Secondly, wholesale LED lights can be used for more than 27 years, even it has been used for 10 years, which prolong the using life of liquid crystal display television, and it can achieve great advance in technology. Thirdly, it is easy to achieve the control of led power, therefore, user can easily adjust the brightness of equipment to the best condition. Fourthly, traditional CCFL tube owns low spangle frequency which will make pictures jump in showing dynamic scene. Led backlight can adjust light frequency flexibly, and its frequency is higher than CCFL. Fifthly, because red, green and blue light flash independently, it is easy to control its display color characteristics
Shortages of LED Backlight

As we know, led backlight is in 10.4 inch, even less than 15 inch, for led use direct current, and it is easy to drive without transverter, and the efficiency can be improved greatly. White led is not really white color, but in fact, it is blue led which is added yellow phosphorus to produce white light. There is gap between green parts and red parts in spectral curve. No matter the size of screen, most screens need more than one led to achieve the brightness, and it is difficult to make the brightness well-distributed. Especially when the problem of led ageing becomes more seriously, then efficiency of power should be considered carefully.

Conclusion

Modern world requires portable products which needs the reduction of cost, weight and consumption on one hand, while on the other hand the multimedia function needs to be added. In addition, the excellent appearance should also be put in the first place. And we should try our best to combine the functions and appearance. Led industry definitely will become leading industry in our life for it plays an important role in our daily life.

Analysis of LED Industry Development

LED Lighting Market Continues to Grow
In 2011, energy issues were paid attention to continuously, the LED lighting market is rising rapidly. The size of high brightness LED market grows from $ 8.25 billion in 2010 to $ 12.6 billion in 2011, and the annual growth rate is up to 53%. The policies of the major countries of the world promote significant improvement of LED luminous efficiency and the overall design of the lighting tend to mature. From the replace LED light source in low power residential to full high-power set of led recessed ceiling lights equipment in commercial and industrial use, all kinds of LED lighting applications demand is rising sharply. It is expected that the global LED lighting market is expected to reach $ 21.7 billion in 2015 and is expected to drive the power supply sales to reach 40 million units of the scale in 2016, and the total output value will reach 10 billion U.S. dollars.

Asian LED Industry Ranks the First in the World
In 2010, Asia has become a major production base of LED, the overall market share in Japan, South Korea and China has reached 81.3%. Among Asian countries, South Korea's growth rate is the fastest. Japan takes the leadership in the global LED industry with its strong quality and technical development capabilities, its market share reached more than 50% from 2000 to 2005. As far as China is concerned, only grasp the overall development of the LED industry in Asia can we grasp the global development context of wholesale LED lights industry.

Special Light Culture in Europe Improves LED Lighting Industry
The overall Europe lighting market is relatively mature, but high tariffs and special light culture make mood lighting, commercial lighting and outdoor architectural LED application demand continue to increase. The high tariff policy in Europe as well as special light culture is an important factor in the rapid development of LED industry. High tariff is good the popularity of LED lighting, take the 7 watt LED bulb which can replace a traditional 40-watt incandescent bulb as an example, if it works eight hours a day, a LED bulb can save $ 2 than traditional incandescent, the outdoor lighting or commercial lighting with higher power consumption will be able to save more costs. Light culture in Europe focus on creating a light environment, rather than simply to emphasize the kind of lighting or brightness level. Lyon, France, for example, the government will put some budget into light construction every year, and organizes the Festival of Lights, establishes an international city lighting joint household, combine both lighting and urban culture with both the tourism and economic benefits.
