Accumulation of science and technology: the mainland market to drive the market thermal technology breakthrough

In October 15, 2008, Taiwan accumulation of science and technology held in 2008 to the latest LED driver technology seminar "in Shenzhen, industry trends, technical problems, market driven dynamic aspects of technology from the company's LED display and LED lighting field, in-depth exchanges with hundreds of enterprises participating representatives.

LED display market presents new trends

As the founder of the company, Yang Lichang, chairman of the cumulative technology has been closely watching the LED display market every move. He believes that the current LED display market presents two major trends, first, the Chinese market will maintain a strong momentum of growth, the European and American manufacturers will continue to shift the production of two processing plants in china.

The first trend, Mr Yang Lichang thinks that the Beijing Olympic Games on the demonstration of large-scale LED application brings, will greatly promote the application of the scale of the LED display, and the upcoming opening of the 2010 Shanghai World Expo will drive the next wave of growth in demand. The second tier cities in China, a huge market space, but also for the LED display market to provide greater prospects for development.

At the same time, based on cost considerations, more and more international LED display manufacturers will seek to OEM in China, which can also greatly enhance the output value and scale of China's LED display. According to Yang Lichang analysis, in 2008 the output value of China's LED display will reach 10 billion yuan, in 2011 will be doubled to $about 20000000000, which can account for the total share of the world's total of 60%.

Color and energy has become the development direction of products

The direction of development about the product, Yang Lichang believes that the color will be the market focus, and its penetrating screen, screen mesh and strip screen does not interfere with the line of sight, light structure, easy assembly and other advantages, will make the LED display in the rental market, suggestions on the stage and get a large number of applications, and will expand to more application areas. In terms of product performance, to use more bits and color contrast, high refresh frequency, point by point correction, temperature compensation and other direction.

In addition, the use of the LED screen, the city began to focus on energy-saving lighting and light damage. This requires the LED chip itself and the drive circuit has a higher performance. The current adjustment function has gradually become the driving chip producing function, power consumption and heat dissipation of the chip itself also needs to be further improved, the following 45 Ma small current driving chip will become the mainstream market, all of which will reduce the current and the temperature can improve the overall performance of the product.

LED display driver chip seek technical breakthrough

As LED display driver chip manufacturers and suppliers, accumulation of science and technology has been deeply rooted in the mainland market for many years, in the competition with Toshiba and TI gradually strong. Since its inception in 1999, the accumulation of science and technology to seize the LED display driver of this emerging product, growing. 2006 set up a subsidiary in the mainland of China Poly letter optoelectronics, in Taiwan in October 2007 successfully listed, when the turnover exceeded 1 billion 200 million nt.

Accumulation of scientific and technological development, Yang Lichang will be attributed to the company's emphasis on technology, it is a breakthrough in technology in the competition with the international manufacturers to win a place.

According to the accumulation of science and technology product development director Mr. Lin Rongzong introduced, in order to satisfy the consistency of LED display uniformity and brightness of the performance, accumulation of science and technology of the LED driving circuit chip has greatly exceeded the market demand, whether it is the consistency of tube current between pins, or chip between consistency, have reached a higher the level of. The error between the pins is not more than 1.5%, the error between the chip does not exceed 3%, support for the 65563 gray color, refresh frequency has reached 3000HZ, these indicators are the world's leading level.
