China's first full-color LED integrated three in one display"

Technology Daily News October 29, 2007 in October 20th, the world's first full color LED display, integrated three in one "by the Chinese Academy of Sciences Institute of optics Changchun Changchun Hilda Electronic Technology Co., Ltd. successfully developed, and first introduced the concept of integration of the three", the subversion of the previous international LED display design ideas, make the world a new generation of LED display screen display effect, reliability has been a major breakthrough, also make the enterprise Chinese first stood in the forefront of the world's LED display industry. Changchun Hilda company after April 20, 2007 successfully developed the world's first full color display LED dot matrix module ", after six months of research, on the basis of the further development of the" three in one integrated full color LED display screen, the LED material cost greatly reduced, simplified production process, product enhance quality.

Is currently "LED surface mount three in one screen for the high-end products industry recognized, but its defect is: high cost, difficult machining. The process of the LED display screen, in the production process to go through a single tube packaging and two welding process, the two welding temperature requirements are more stringent. If the temperature is too high to damage the tube core temperature is too low, easy to produce. The welding temperature of two times, the alignment accuracy of the machine, the welding material and the thickness of the plate have great influence on the reliability. The manufacturing cost of this kind of light emitting device is very high, and the cost of the LED display with reliable performance after two welding is higher. Moreover, the surface mount light emitting device has a small volume, and is difficult to seal. In addition, the pin of the light emitting device is welded on the circuit board, which is easy to be damaged in the process of installation, use and maintenance. The higher price and more complex production process can not be a large number of promotion.

"Full color LED three in one integrated display" come out, will change the current world LED display market by "LED surface mount three, LED surface mount three spell" and "LED matrix module" and "LED separation line" and other products occupy the pattern. Compared with these products, "full color LED integration of the three one" the cost of raw materials and production equipment into the lowest cost, than the "LED stick three" to reduce the cost of 40%; and in the display process, can realize the reliability, products and other aspects is far better than other products in the world LED display market the.

"Three in one integrated display" is the encapsulation mode LED light tube core IC in a matrix module. A welding process which has the ultrasonic welding technology, to avoid the direct contact pin and the welding torch, solder paste, flux, completely solve the LED display high dependence on the accuracy of the equipment, technology difficult problem of large-scale production. "Three integration" combination package with an integrated block mode with independent intellectual property rights, seal material and seal thickness to fully meet the LED light emitting chip antioxidant requirements to ensure product reliability, thus eliminating the interference of temperature, humidity and electrostatic and other negative factors, to avoid the LED display installation, use and maintenance process easily affected by the electrostatic environment and personnel. In addition, the technology also changes the cooling strategy for heat dissipation design, from the design concept to solve the heat problem.

It is reported that the scientific and technical personnel of each of the 3 million "surface mount three" pixels and 10 million "integrated three" pixels in the same conditions of reliability test. The pixel failure rate of "table three in one" is 4/10000, while the "integration of the three in one" pixel failure rate of less than 3/100000, an order of magnitude difference.

"Full color LED three in one integrated display" is Changchun Hilda company after ten years of scientific research and major innovations achieved, its development of the pointwise consistency of brightness and color correction technology "is one of the world's LED shows a major breakthrough in the field. The production of "high definition and high uniformity of full color LED large screen flat panel display, a recent representative China Academy of Sciences Major Innovation Exhibition exhibition project," 2007 Northeast Asian High Tech Expo ", more than 2000 talent shows itself in the high-tech enterprises in the Northeast Asia, won a gold medal. At present, from the United States, Japan, Russia, Hong Kong and Macao and domestic manufacturers have said around to various forms, extensive cooperation with Changchun Hilda company.
