Core Viewpoint - The emergence of Nanjing Gaoguang Semiconductor Materials Co., Ltd.'s G8.6 generation CMM+FMM high-generation product combination at the DIC EXPO 2025 is a significant technological advancement aimed at breaking the barriers to the rise of China's OLED display industry [1][4]. Group 1: Industry Context - The metal mask is a critical tool in the production of AMOLED displays, directly influencing yield and image quality. It is categorized into three types: Common Metal Mask (CMM), Chemical Vapor Deposition Mask (CVD Mask), and Fine Metal Mask (FMM), with FMM being essential for high precision in AMOLED manufacturing [2][3]. - Historically, Chinese OLED panel manufacturers have relied heavily on imported metal masks, with DNP holding nearly 90% of the FMM market share and Korean manufacturers dominating the CMM and CVD Mask sectors [2][3]. Group 2: Company Development - Nanjing Gaoguang, established in May 2013, is one of the few domestic manufacturers of ultra-precision metal masks for AMOLED displays. The company has developed capabilities to supply G6 and lower generation metal masks, and there is a growing demand for domestic G8.6 generation metal masks as higher generation AMOLED lines are being constructed in China [3][4]. - In March 2024, BOE announced the groundbreaking of China's first G8.6 generation AMOLED production line in Chengdu, with a total investment of 63 billion yuan, marking a new era for domestic AMOLED high-generation lines [3][4]. Group 3: Technological Innovations - At the DIC EXPO 2025, Nanjing Gaoguang showcased its full series of G8.6 generation AMOLED CMM, CVD Mask, and FMM, highlighting its capabilities in ultra-precision manufacturing and high-generation adaptation [5][6]. - The G8.6 generation CMM measures 2.5 meters in length and 1.5 meters in width, made from high-purity iron-nickel alloy, which significantly enhances the uniformity of electrical performance in AMOLED panels [5][6]. - The G8.6 generation FMM can achieve a hole precision of ±2.5μm and is suitable for large-size AMOLED panel production, with a maximum width of 600mm and a length exceeding 1.75m [7][8]. Group 4: Market Trends - The global FMM market is projected to grow from $365 million in 2024 to $952 million by 2031, indicating a shift in the industry landscape from Japanese monopoly to multi-polar competition driven by the rise of Chinese companies [8][9]. - Nanjing Gaoguang has established a dual-track system covering both metal masks and organic light-emitting materials, positioning itself as a one-stop supplier for AMOLED production [9][10].
