Summary of LIPO Technology and Investment Opportunities Industry Overview - The document discusses the LIPO (Low-Pressure Injection Molding) technology, primarily used in mobile phone screen packaging, enhancing waterproof performance and drop resistance while reducing costs in other processes [2][4][5]. Key Points on LIPO Technology - LIPO technology allows for ultra-narrow bezels, reducing the width from over 2mm to below 1.5mm, and improves the overall aesthetics and functionality of mobile devices [5][6]. - Apple was the first to adopt LIPO technology in 2021 for the Apple Watch and has since integrated it into the iPhone 15 Pro series in 2023, with Android devices expected to follow suit starting in 2025 [2][6][7]. - The technology incurs an additional packaging cost of 20-30 yuan but offsets this by reducing costs associated with glue application and testing processes [2][5]. Market Potential - The global sales of small and medium-sized OLED smart terminals are projected to exceed 1.1 billion units by 2025, with smartphones accounting for approximately 660 million units [2][8]. - The penetration rate of OLED packaging technology in smartphones is expected to rise from 12% in 2025 to 55% by 2028, indicating significant growth potential for related companies [9]. Investment Opportunities - Key investment opportunities are identified in two areas: packaging processes (represented by Longli Technology) and photosensitive resin materials (represented by Debang Technology) [3][10]. - Longli Technology is positioned to benefit from the LIPO technology's adoption in smart terminals and is expected to see profits grow by 89% in 2025 and 52% in 2026 [4][13][14]. - Debang Technology, a major supplier of photosensitive resins, is projected to maintain high growth rates, with profits expected to reach 150 million yuan in 2025, a 72% increase year-on-year [12]. Competitive Advantages - Debang Technology has a strong position in the photosensitive resin market, with a market potential estimated between 1 to 2 billion yuan, and is involved in high-end electronic packaging materials, particularly in integrated circuits [11][12]. - Longli Technology holds a first-mover advantage in LIPO packaging processes and is also a leader in the automotive mini backlight business, which is expected to grow rapidly due to trends in automotive display technology [13]. Impact of Tariffs - Both Longli Technology and Debang Technology are minimally affected by U.S. tariffs due to their low direct export ratios (below 1%) [15]. - The potential for domestic substitution may actually benefit these companies in the long term, making current stock price corrections an attractive buying opportunity [15].
