OLED Universal Layer Materials: Supply Landscape and Domestic Competition

On the supply side, overseas suppliers of Prime materials include LG Chem, Tokuyama, and Doosan (Solus); domestically, LeiTe Optoelectronics’ Red Prime and HaiPuRunSi’s Green Prime have entered mass production supply to panel manufacturers. Overseas suppliers of HBL materials are primarily LG Chem and Doosan (Solus); domestically, HaiPuRunSi has achieved mass production supply of HBL. 4. Light Extraction Layer (CPL): Affects light extraction efficiency, brightness, and viewing-angle color performance The Light Extraction Layer (CPL) is neither conductive nor emissive; its function is to extract photons trapped inside the device by total internal reflection through refractive index matching, while simultaneously leveraging microcavity effects to calibrate chromaticity coordinates and improve viewing-angle color shift—especially at wide angles—and providing both anti-reflection and cathode protection functions. Once the CPL fails, a large number of photons remain trapped within the device, causing a marked drop in maximum brightness; changes in emission angle further exacerbate brightness and color degradation when viewed from the side. The key technical challenge lies in developing materials that simultaneously exhibit a high refractive index (typically requiring n > 2.1) and near-zero absorption across the visible spectrum—a formidable challenge for organic molecules. Additionally, materials must possess a high glass transition temperature (Tg) to withstand thermal evaporation, and the refractive indices across red, green, and blue wavelengths must be as uniform as possible. Process-wise, the optical performance of the CPL is extremely sensitive to thickness, with an extremely narrow optimal thickness window; achieving uniform thickness control over large-area substrates becomes increasingly difficult with each successive generation. As a result, the industry has evolved two main approaches: single-layer and double-layer structures—the latter separates the ‘light extraction’ and ‘anti-reflection’ functions, and is regarded as a key developmental direction. At a stage where efficiency gains from RGB emissive materials are plateauing, the leveraged impact of CPL on overall device efficiency and color gamut is further amplified. Overseas CPL suppliers include Doosan (Solus), Tokuyama, and Nippon Soda; domestically, HaiPuRunSi and SanYue Technology have achieved mass production and commercial supply of CPL materials. IV. Market Demand and Localization Stage: From “Functional” to “High-Performance” Reviewing recent growth dynamics, 2022–2023 marked a critical period during which China’s Gen-6 OLED production lines began large-scale shipments and ramped up output significantly; in 2023, China’s total OLED material consumption grew nearly 80% year-on-year. Subsequently, as panel makers completed their capacity ramp-up and downstream end-device demand faced temporary pressure, overall market growth slowed. However, starting in 2027, with the gradual commissioning of Gen-8.6 production lines targeting IT products and accelerated adoption of tandem architectures in mid-sized terminals, the OLED materials market is expected to enter a new growth cycle. More notably, this market expansion is driving domestic competition beyond mere functionality (“can it work?”) toward high-performance readiness (“does it work well?”). In early stages, panel manufacturers’ primary requirement for domestic materials was simply to resolve supply availability—materials mainly served as critical backups and cost-optimization tools. As domestic materials progressively entered actual production processes, evaluation criteria have shifted toward comprehensive comparisons encompassing performance, stability, cost, mass-production yield, and supply capability. Specifically, performance evaluation no longer focuses solely on whether a material passes qualification tests, but rather compares key metrics—including driving voltage, current efficiency, LT95 lifetime, chromaticity coordinates, and viewing-angle color shift—under identical device architectures. Stability assessment covers raw-material purity, impurity profiles, sublimation recovery rates, batch-to-batch consistency, and long-term evaporation behavior. Cost considerations extend beyond unit price to include material utilization rate, evaporation loss, and supply-chain proximity.
