It is understood that the display is completed by more than 10 years of scientific and technological research by the researcher of Changchun Xida Electronic Technology Co., Ltd. of Changchun Institute of Optics and Physics, Chinese Academy of Sciences. According to researcher Wang Ruiguang, the person in charge of the development, the core technology of the LED display screen is “the brightness and color point-by-point uniform correction technology for LED display screens suitable for large-scale mass production†with completely independent intellectual property rights. The international LED display design ideas have made China stand at the forefront of the world LED display industry for the first time. At present, this achievement has applied for 12 patents, including 9 national invention patents, marking that China's LED display has ranked among the world's first.
At present, the world LED display market is dominated by products such as “three-in-oneâ€, but its inevitable defect is that the LED display with surface-mounting process has to be single-tube packaged and twice in the production process. Two processes of welding, the temperature requirements for secondary welding are more stringent. Too high a temperature can easily damage the die, and if the temperature is too low, it is easy to produce a virtual solder. The secondary welding requires high precision in the manufacturing process. The welding temperature, the alignment accuracy of the placement machine, the welding materials used, and the thickness of the stencil all have a great influence on its reliability.
According to reports, the emergence of "integrated three-in-one" will change the current pattern of the world's LED display market dominated by "three-in-one". Compared with the "integrated three-in-one" raw material cost and production equipment input cost is very low, and in terms of display effect, process achievability, product reliability, etc., the product cost-effective, will become the mainstream of the future.
