The development of domestic LED light guide plate industry bottlenecks

LED China is the fastest growing region in 2010, but the momentum did not continue in 2011, many companies operating conditions are not ideal, even collapse phenomenon, but it is undeniable that lay a solid foundation for China's LED lighting industry, is still the world's largest development area.

LED guide the development trend of light industry sectors, as one of the LED lighting accessories, plays an important role in the development of the industry, is also one of the industrial sectors in China have the scale and cost advantages in the global semiconductor lighting industry chain of division of labor.

With the continuous promotion of backlight and lighting and other applications, the market demand for the LED of the light guide plate is continuously changing, the current and future market demand, backlight and lighting will become the main application, more and more high request to the LED light guide device, low level screen light guide plate is difficult to meet the needs of the quality of LED the field of application.

With the gradual expansion of China's light guide enterprises, many companies have started competing for the market, the opportunity for financing. LED light guide plate industry, the degree of concentration, the size of a single enterprise and the degree of automation will be greatly improved. With the change of the LED light guide plate pattern, the laser light guide plate also has the prominent characteristic.

Although the light guide plate industry is facing a bright future, but because of its own light, mixed light difficult to hinder the development of the LED industry is also hindered the development of their own.

First, in the light of the LED design, a very vexing problem is how to point the LED light source to enlarge the surface imaging, and through the LED array design and diffusion micro architecture to achieve high brightness and high uniformity. These techniques are often closely related to the design and fabrication of optical microlenses, the planar LED packaging technology (mainly to improve the light emitting angle), and the research and development of uniform hybrid optical technology.

Second, LED can be designed into any shape flexibility, but the complexity of the shape it will restrict the LED itself, causing power design difficult, double-sided nature of the characteristics of the shape design must have a good grasp of the scale LED.

Third, LED is a point light source, it must be repeated reflection in the light guide plate. When the light reflection occurs, there will be a part of the light diffusion from the convex dot, from surface illuminate the screen, so it must be light as thin as possible, so as to get higher brightness. At present, the industry's thinnest LED light guide plate thickness is about 0.8mm, the demand for thinner, better reflection light guide plate is more and more urgent, but the current processing technology can not meet the requirements.

To sum up, the nature of the LED thin light determines the market demand. However, in the face of technical difficulties at present, producing more thin light guide plate cost efficiency will increase, the efficiency will be reduced, and the cost is high, which in the competition with CCFL is definitely not "positive factors". So manufacturers will be how to deal with? Whether through the light guide plate processing risk? These problems placed in front of the light guide plate manufacturers, these issues will be resolved, but what specific time can be eliminated, we continue to focus on.
