“In 2009, the LED-backlit LCD TV market was officially launched. The LED-backlit LCD TV reached 3.3 million units, but it only accounted for 2.4% of the 140 million LCD TVs. In 2010, it will reach 26 million units, accounting for 16% of LCD TVs. "Fang Zhilie, a professor at Fudan University, said recently.
For large-size LED backlight applications, LED backlight LCD displays of more than 25 inches are mainly used for flat-panel TVs. Professor Fang believes that with the continuous improvement of LED efficiency in recent years, new technologies and solutions are also being proposed in LED selection and secondary optical design, LED backlight module design, thermal management design, and drive control technology. By utilizing the characteristics of the LED point light source, the problem of large power consumption and heat dissipation caused by insufficient luminous efficiency of the LED light source is gradually solved, and the overall performance of the LCD TV is greatly improved, and the cost is also greatly reduced, which is a large quantity. Entering the market is ready for technology and cost. In addition, the current LED backlight in the (12 ~ 15 inch) range can not only save power, but also make the computer thinner, the weight can also be reduced, coupled with a better display effect, so that the LED backlight is already The notebook market is spreading rapidly. Many companies' laptops will be fully integrated into LED backlights. Professor Fang said that the technology development in this size field is mainly thinner, lighter and more power efficient. The LEDs used are also white LEDs, the main improvement being the use of thinner light guides.
In addition to the backlight application, in the indication display application, Professor Fang believes that the automotive lighting market has great potential and should increase the research and development of this type of automotive lighting. Another type of LED lamp on the car is the headlamp. The international development has made breakthroughs. Many brands of LED car headlights have been put into mass production and loading. Audi 6.0 is the first day of the car. The light was introduced and in 2007 Toyota's Luxus LS 600h was used as a low beam headlamp. In December 2009, Audi released the new A8 with full LED headlights, including low beam, high beam and daytime running lights, as well as yellow LED directional lights. The white color temperature is 5500k. With an annual output of 60 million vehicles in the world, China's automobile production and sales volume reached the highest in the world in 2009, and the potential market is very impressive. In addition, the development and market of LED car signal lights have made great progress and began to enter the market expansion stage. Whether it is high brake lights, brake lights, direction lights, position lights, and interior lights, it has grown steadily every year. In 2009, the output value reached 1.2 billion yuan. In terms of display applications, the market size of LED displays reached 12 billion in 2009. Product technology and standards have been perfected. In 2007, due to the business opportunities of the Beijing Olympic Games, it achieved an annual growth rate of 44%. The construction of major projects for the 2010 Shanghai World Expo is expected to increase significantly. At present, there are nearly 400 LED display manufacturers, with nearly 20% of exports. There are 20 companies with an annual output value of more than 100 million, and some of them currently have a tendency to extend to landscape lighting and general lighting such as LED tunnel lights and LED street lights .
In addition, landscape lighting application is one of the current concerns in the industry. In this regard, Professor Fang pointed out that with the further expansion of Shanghai World Expo construction and urbanization, the proportion of landscape lighting applications will further increase. At present, landscape lighting has become an emerging industry, technology has matured, construction and acceptance have also become standardized, and it is developing in the direction of intelligence, art, and human culture. According to statistics, the average investment of 37 megacities in China is 150 million yuan, over 100 million in 51 large cities, more than 8 million yuan in nearly 600 small and medium-sized cities, and an average of 2 million yuan in more than 2,000 county-level and other small cities and towns. The application of LED landscape lighting will reach 500 million yuan. With the construction of Shanghai World Expo and the further acceleration of urbanization, the proportion of landscape lighting applications will further increase. Professor Fang also said that the market potential of tunnel lights, subway stations, gas stations and underground parking lot lighting and indoor lighting LED bulbs in the field of general lighting is huge.
