From 1998 when China began to try to independently produce display panels to 2018, a full 20 years have passed. China's display panel industry has gone from catching up to following and gradually leapfrogging to the position of the largest production scale. Especially in recent years, "Made in China" is gradually transforming to "Smart Manufacturing in China". In this context, the LCD industry, as one of China's emerging industries and also as a technology industry in the physical manufacturing industry, has a long and arduous road to transformation and a long way to go to achieve intelligence.

In terms of production technology, the development of LCD panels towards large size and ultra-high definition has become an inevitable trend, and driven by consumer demand for large-screen TVs, the average size of global TV panels has steadily increased, and the process of large-size has accelerated, driving the continued growth of demand area. In particular, for LCD panel products above 65 inches, the most economical cutting efficiency is the 10.5-generation line.

Another thing we can see is that most of the newly expanded OLED production lines at home and abroad are flexible OLED production lines. Take a well-known domestic company as an example. The two 6-inch OLED production lines in Chengdu and Mianyang, which cost nearly 100 billion yuan to build, are both flexible OLED production lines. It is expected that the increase in flexible OLED production capacity of newly opened production lines after 2018 will be more than twice that of rigid OLED. It is expected that by 2020, the proportion of flexible OLED will increase from 27% in 2016 to nearly 62%.

Whether it is the 10.5-generation large-screen panel or the OLED flexible screen, the factory environment is undoubtedly very demanding, especially the chemical volatile pollutants in the air, which will affect the manufacturing process of flat panel display products, thereby reducing the yield rate. So it is no exaggeration to say that pollutants in the air are the enemy of all electronic industries, and a closed production environment that can block all kinds of particulate dust, moisture, harmful gases and substances is needed.

AAF Microelectronics Industry Solutions

As a global leader in clean air solutions, AAF has been committed to developing efficient and energy-saving filtration solutions for the microelectronics industry for more than 90 years, including particulate matter and AMC (molecular gaseous contaminant) filtration. The full range of products covers coarse, medium and high efficiency air filters, chemical filters, high efficiency air outlets, FFU/EFU, laminar flow hoods and other purification equipment. With advanced production, rigorous management, excellent quality, efficient performance, complete testing services and ultra-high TCO (total cost of ownership), it is widely used in various industries such as semiconductors, electronics, flat panel displays, photovoltaics, etc., providing a full range of purified air solutions to meet customers' requirements for different purification levels.

AAF launches new filtration technology to improve product yield

As the world's largest manufacturer of air filtration solutions, AAF is also the only factory that has the entire production supply chain and full quality traceability from raw materials to finished products. Its products not only combine the world's leading clean technology, but also continuously develop new high-tech products on the existing basis, catering to the needs of various fields and receiving unanimous praise from customers from all walks of life.

Through continuous investment in research and development, AAF has launched MEGAcel ^® ePTFE filtration technology, with the highest filter efficiency being U17. The filtration efficiency for 0.1-0.2um particles exceeds 99.99999%, ensuring high cleanliness in the factory and greatly improving the product yield.

除此之外，在同样条件下，MEGAcel ^® ePTFE 产品的阻力为传统玻纤过滤器的50%。而强度则达到玻纤的数倍甚至打摺后的数十倍。并且由于MEGAcel ^® ePTFE 过滤器阻力低，阻力上升速度慢，从而可以降低HVAC整体系统阻力、降低系统能耗，节能超30%。

In terms of products, AAF will not even miss any details. In order to provide a precise and reliable sealing system, AAF uses a fully automatic polyurethane PU sealing gasket machine. Through the process of precise dispensing and foaming, the sealing material is poured on the part of the filter that needs dispensing to achieve waterproof, dustproof, flame retardant and other effects. The entire automatic sealing edge sealing process is efficient, safe and fast. After the polyurethane PU foam sealing material is cured, there is no joint gap, and the sealing effect and comprehensive performance are higher than the EPDM rubber sealing gasket currently commonly used in China.

Excellent products come from rigorous testing

In addition, in order for AAF to continue to maintain its leading position in the supply of high-end air filtration products in China, three of the world's most advanced fully automatic HEPA&ULPA filter scanning and leak detection test benches, AstroScan, were recently installed in AAF's Suzhou and Shenzhen factories. This not only allows AAF to more strictly comply with the current EU EN1822:2009 standard and the ISO29463 standard that will be implemented globally, but also ensures the ability to automatically scan and test 1,000 HEPA&ULPA high-efficiency and ultra-high-efficiency filters one by one every day.

AstroScan Leak Detection Scanning Test Bench

AAF also has a world-leading chemical laboratory equipped with high-end large-scale analytical testing instruments such as gas chromatography-mass spectrometry and ion chromatographs, allowing AAF to collect gas samples directly at the customer's site and analyze the sample gas composition. This not only greatly shortens the time for gas sampling and analysis, but also facilitates the provision of follow-up tracking services to customers, enabling AAF to serve customers more efficiently and with higher quality, and provide customers with more complete solutions.

Gas chromatography-mass spectrometry, ion chromatography

The FFU testing laboratory jointly established by AAF Suzhou Factory and Shanghai Tongji University, combined with the AstroScan fully automatic leak detection scanning test bench and chemical laboratory, makes AAF the only filter manufacturer in China that can provide chemical testing capabilities from high-efficiency filters to FFU equipment.

AAF has always taken protecting the environment, reducing corporate risks and reducing air purification expenses as its mission. It continues to challenge itself in technology, improve and perfect the process, and strive to provide customers with a perfect product and solution, contributing to the Made in China 2025 plan.
