Core Viewpoint - The display glass substrate is a critical component of display panels, accounting for approximately 15% of the cost of TFT-LCD panels, and is facing a shift towards higher pricing due to rising energy costs and market dynamics [2][5][23]. Group 1: Display Glass Substrate Overview - The glass substrate is a core raw material for display panels, with about 80% of display glass substrates used for LCD panels [1][23]. - A TFT-LCD panel requires two glass substrates, while an OLED panel primarily uses one as a carrier glass [1][23]. Group 2: Market Development - Major glass substrate manufacturers like Corning, AGC, and NEG are shifting focus from market share expansion to improving profitability due to rising energy costs, which account for over 50% of production costs [2][38]. - The global market for FPD glass substrates is expected to reach approximately 50 billion yuan (about 7.05 billion USD) by 2025, with a projected revenue growth of 15% from 2024 [2][39]. Group 3: Demand and Supply Dynamics - In 2024, the demand for FPD glass substrates is projected to be 645 million square meters, with a year-on-year growth of 4.34% and a supply surplus rate of 7% [3][39]. - By 2025, demand is expected to increase to 679 million square meters, with a further reduction in the supply surplus rate to 5% [3][39]. Group 4: Competitive Landscape - The market concentration is high, with the top three companies (Corning, AGC, and NEG) holding about 80% of the market share [4][46]. - Domestic manufacturers have accelerated the pace of localization, with companies like Rainbow Technology making significant breakthroughs in high-generation glass substrates [4][48]. Group 5: Investment Recommendations - With China holding 70% of global LCD production capacity, the demand for glass substrates is increasingly concentrated in China, prompting many related companies to establish factories there [5][6]. - Rainbow Technology has shown promising results in mass production of high-generation glass substrates, and as initial investment costs decrease over time, its profit margins are expected to improve [5][6].

Investment Rating - The report recommends a "First-time Buy" rating for the industry [5] Core Viewpoints - The domestic glass substrate industry is experiencing a significant shift towards localization, with major breakthroughs in high-generation glass substrate technology by domestic companies [8] - The global market for FPD glass substrates is expected to reach approximately 50 billion RMB by 2025, driven by price increases and rising demand [3][44] - The competitive landscape is dominated by three major foreign companies, which hold about 80% of the market share, but domestic manufacturers are rapidly increasing their market presence [4][51] Summary by Sections 1. Display Glass Substrate Overview - Display glass substrates are a core component of display panels, accounting for approximately 15.2% of the cost of TFT-LCD panels [2][27] - The demand for glass substrates is primarily driven by the LCD panel industry, with about 80% of glass substrates used for LCD panels [2][27] 2. Development of Display Glass Substrates - Major glass substrate manufacturers, including Corning, AGC, and NEG, have raised prices by over 10% in response to rising energy costs [3][43] - The global market for FPD glass substrates is projected to grow by 15%, from 6.12 billion USD in 2024 to 7.05 billion USD in 2025, equivalent to about 50 billion RMB [3][44] 3. Competitive Landscape - The top three companies (Corning, AGC, and NEG) control approximately 80% of the FPD glass substrate market, with Corning leading at over 50% market share [4][51] - Domestic manufacturers have made significant progress in high-generation glass substrate technology, with companies like Rainbow Technology achieving notable production milestones [8][19] 4. Investment Recommendations - Given the clear trend towards domestic production of high-generation glass substrates, companies like Rainbow Technology are recommended for investment due to their technological and market potential [8][9]
