The world's first stereo LED
At the opening ceremony of the 29th Olympic Games, China conquered the world with a magical and magnificent visual feast with Chinese characteristics. In fact, this is not only a beautiful opening ceremony, but also an unforgettable moment in the history of LED technology application in the world. LED technology has been thoroughly applied in all aspects of the opening ceremony, especially in the center of the stage, the screen like the Chinese landscape painting, which is even more amazing in the world. As a high-tech technology in the field of international display technology in recent years, LED has been favored by people with its concept of energy saving, environmental protection and technology, and has been applied in more and more occasions. Recently, the leading company in the domestic 3D display industry has created the first stereoscopic LED, which is the first to combine the stereoscopic imaging technology with the LED technology.
In 1923, Lossew ow discovered the light emission in the accidentally formed PN junction in semiconductor SiC, but the use of semiconductor PN junction electroluminescence to make LEDs was rapidly developed in the late 1960s. In the 1980s and 1990s, due to the maturity and improvement of semiconductor fabrication and processing technology, LED (Light Emitting Diode) has its own characteristics: high brightness, high power consumption, high reliability, long service life and environmental adaptability. Strong ability, high price performance ratio, low cost of use, etc., are widely used in weak areas such as signal indication and digital display. Although many display technologies have entered large-scale display fields, such as LCD, PDP, and even emerging display PTAs, LEDs have the following advantages in large-scale display applications, such as water, dust, sunlight, and other harsh environments. High impact, high brightness, high product reliability, can be made up to 500 inches in size, life expectancy of more than 50,000 hours (referring to attenuation of luminance to one-half), this feature is not only difficult for other types of display technology Competing, and make up for the shortcomings of LED applications on large displays (such as the uniformity of each LED, LED heat dissipation, point spacing is still large).
According to the staff of Chuangtuvision, Chuangtuvision is aware of the unique advantages of LED technology in the display field, and then the idea of ​​manufacturing the world's first three-dimensional LED, combining LED with 3D imaging technology. It is a great feat of the global display industry. Although some scientific research institutions in other countries in the world have tried similarly, there are no molded products. This time, Chuangtu Vision has been preparing for R&D for nearly one year, and finally completed the world's first three-dimensional LED production on the occasion of the National Puqing Olympic Games. It has become a major gift of the Beijing Olympics and successfully appeared in Beijing CITIC Guoan Cyberport. Participate in the half-monthly on-site Guoan Cyberport and experience the 3D new technology three-dimensional display month event.
Looking ahead to the future of large-scale LED display, there are also many factors driving the growth of large-scale LED displays. The opening ceremony of this Olympic Games is a model for the successful use of LED technology, and it will certainly drive new demand for LEDs in the application of sports venues. It is estimated that there will be new demands for the 2010 Shanghai World Expo and various major sports events in the future. The large LED display screen will be erected every 10 years. In terms of billboard usage, because the prime location in the big city is still the preferred location for advertising owners, especially in the periphery of the building and on the periphery of the highway, it will be the medium for the owners to effectively use outdoor advertising, so the large LED display There will be a continuing need for additional erections.
According to estimates by DIGITIMES, the LED output value of large LED display screens was 1.18 billion, 1.64 billion, and 2.32 billion US dollars from 2008 to 2010, respectively. The annual growth rate was 34.1%, 39%, and 41.5%, respectively. Among them, the product with the most significant annual growth rate. While everyone is paying attention to the development of LED backlights for LCD displays, the application of LEDs in large-scale displays cannot be ignored. The reason is that they use more pixels, have more irreplaceable characteristics than other display technologies, and have a wide range of applications. Growth potential and so on.
As a combination of high-end technology of 3D imaging and LED, stereo LED will have its unparalleled advantages in terms of technology content and actual display effect. On the basis of inheriting the characteristics and advantages of traditional LED display, the three-dimensional LED screen adds 3D display effect, can truly reproduce the original appearance of the landscape, and has a unique three-dimensional infiltration, which can bring people a unique visual enjoyment. Moreover, in the play mode, the stereo LED can successfully realize the free switching of the 2D/3D program, and the multi-purpose in the true sense can satisfy various display requirements of product display, advertisement communication, game broadcast, stage effect and the like.
