Flat panel displays & LEDs

Supporting Leading Display Manufacturers with Proven Expertise

As end products continue to elevate the visual experience, display technologies are moving rapidly toward higher resolution, enhanced brightness, and more flexible structures. Widely applied in TVs, smartphones, tablets, and wearable devices, the next-generation transparent OLED displays are driving the demand for gases with even higher requirements. For processes such as deposition, etching, and cleaning, there is growing emphasis on purity, response speed, and process control. As manufacturing precision and process consistency become critical to performance, the challenge of maintaining system-wide gas reliability is also increasing. Messer has become the preferred gas partner for several China’s leading display panel and LED manufacturers. Leveraging its localized production bases and experienced technical team, Messer has supported the major customer projects from fab construction to daily operations. As the gas supplier for the G8.6 production lines, Messer brings deep engineering expertise and practical know-how across the entire supply chain—from bulk gases station to high-purity gas delivery.
