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.
