Ten years of grinding a sword. The Changchun Institute of Optics and Physics of the Chinese Academy of Sciences Changchun Xida Electronic Technology Co., Ltd. has successfully developed the world's first "dot matrix module full-color LED ultra-high uniformity display" after more than ten years of scientific and technological research.
Innovative technology wins the market
Researcher Wang Ruiguang, general manager of Hida Company, said in an interview with China Electronics News that the core of this new type of LED display is the brightness and color of LED display screens suitable for large-scale mass production with completely independent intellectual property rights. Degree-by-point uniform correction technology, this result has applied for 12 patents, including 9 national invention patents. Mastering this technology marks that China's LED display has entered the world's advanced ranks.
According to Wang Ruiguang, brightness, chromaticity, sharpness, viewing angle, contrast, and uniformity are the six indicators for measuring the effect of LED displays. Usually, the LED display is composed of hundreds of thousands or millions of light-emitting diodes. Due to the discreteness of the components themselves, it is difficult to achieve high uniformity of the display by sorting, which also leads to domestic LED color. Large display products are difficult to upgrade, and exports are also low-end products.
The brightness and chromaticity point-by-point uniform correction technology for LED display for large-scale mass production not only realizes the brightness of the illuminating base color, but also eliminates various color deviations during display, ensuring uniformity of color and brightness of the whole screen. Consistency, and the use of high-precision display grayscale control technology, the display has 4 trillion color performance capabilities, can reproduce non-linear reproduction of 1.6 billion colors. In addition to technological leadership, lowest raw material costs, and simple production processes, quality stability is another advantage, and its manufacturing cost is about 20% lower than the current “single-lamp discrete LED displayâ€. In the past, the cost of one pixel (red, green, and blue) of the LED display exceeded 1 yuan, and the new technology did not exceed 0.8 yuan.
The market's good and bad market has the final say. At the 2007 China National Exhibition of China and the 2nd China International Optoelectronic Information Technology Expo, Hida used 18 square meters of "single lamp discrete LED display" made by "brightness and chromaticity point-by-point uniform correction technology". "Screen" has become the biggest highlight of the exhibition. This product is comparable to Daktronics in the United States and Barco in Belgium, regardless of its technical level or display effect, and it has a great advantage in terms of application. A number of Russian distributors have signed an intentional cooperation agreement with Hida. China and Hong Kong, Shenzhen and Japan, South Korea and other large domestic and foreign companies have also proposed the willingness to cooperate with Changchun Xida.
The next step is to increase the scale
The market is on fire, but the meat to the mouth can't be eaten. The anxiety can be imagined. Wang Ruiguang said that relying on the technical advantages of the Chinese Academy of Sciences, the company's talent team, research and development capabilities, and technology accumulation advantages are obvious, but due to market development capabilities, weak financial risk tolerance, the company's development is slow, and has not been loaned, sales in 2006 The income is only 10 million yuan. However, he also pointed out that from the current development situation, this small-step and slow-moving strategy may not only restrict the development of enterprises, but may even be eliminated. For this reason, Hida consciously enlarges the enterprise as soon as possible, especially in technological breakthroughs. After maturity, it also has a foundation for rapid development. Many partners are optimistic and want to understand and use this technology. The company will selectively cooperate with it and develop the market with the cooperation of the market and financial resources of the partners.
Wang Ruiguang revealed that the company's scale this year will increase from 10 million yuan last year to 30 million yuan, and will reach 100 million yuan next year. He said that to achieve such a jump, it is also facing a severe test: not only to solve the liquidity and market problems of plant equipment, but also to solve management problems, the company is introducing senior management talents. He further analyzed that nowadays, the domestic market demand for this product has exceeded 6 billion yuan, and in the future it can occupy 20% of the market share. Together with partners, it can account for 30% in the future. Therefore, the annual output value exceeds 2 billion. Yuan is a very worthwhile goal.
It is understood that Hida has built a 5,000-square-meter factory in Changchun Sino-Russian Science and Technology Park. It is expected to be put into use in October this year. At that time, its dot-matrix module full-color LED ultra-high uniformity display can produce up to 10,000 square meters of LED. Screen module. However, Wang Ruiguang said that due to the short supply in the market, the current production capacity is far from enough.
