Evolution of Anhui's manufacturing sector
Inland province has emerged as one of China's fastest-rising production centers
Battle fought in microns
Inside Hefei Lucky, that transformation can be held between two fingers. Place one of its polarizing films over a demonstration LCD screen and an image suddenly appears. Remove it, and the image disappears.
Zhu Yejian, deputy general manager of Hefei Lucky, said the company mainly produces optical films used inside LCD televisions, which include reflective films, diffusion films and composite films, as well as base materials used in polarizing films.
"These products also extend into laptops, smartphones, multilayer ceramic capacitors and protective films for foldable phones," Zhu said. "They may look simple, but making them reliably is not. Twenty years ago, most of these films relied on imports."
The problems were often microscopic: scratches, tiny surface defects, unevenness, thermal instability and optical imperfections. Over two decades, Hefei Lucky repeatedly upgraded equipment and production processes to tackle those issues, Zhu said, allowing the company to substitute domestically made products for imported ones in areas it had targeted.
It captures one of the quieter shifts in Chinese manufacturing.
A generation ago, industrial progress was often measured in tons of steel, kilometers of production line or millions of units rolling from factories.
Now some of the toughest industrial battles are fought across microns.
The accumulated skills that Lucky once used to make photographic film — forming films, coating them and controlling microscopic structures — did not disappear with the camera roll. They migrated into materials buried deep inside modern electronics.
The surrounding district tells a similar story.
Hefei Xinzhan High-tech Industrial Development Zone has gathered nearly 300 companies across the new-display supply chain, including BOE, Visionox and SeeYA Technology, creating a cluster in which panel makers, material suppliers and equipment companies sit increasingly close to one another.
That clustering matters because modern manufacturing competition is increasingly less about a single finished product than about how much of the difficult technology underneath it can be controlled, improved and scaled locally.
