Скачать или смотреть OLED Color Patterning Technologies and Manufacturing Tools

The provided text offers a comprehensive technical overview of OLED color patterning technologies, which are crucial for achieving cost-effective, high-productivity organic light-emitting diode displays. Initially, the document discusses the limitations of conventional methods, such as the shadow mask technique, and outlines four key criteria for optimal patterning, including high dimensional accuracy and minimal shadowing effect. A significant portion of the text focuses on various patterning alternatives, including the Blue Common Layer (BCL) structure, which relaxes pixel size limitations, and the polychromatic pixel arrangement, which improves lifetime by reducing current density. Furthermore, the source details alternative color display methods like White+Color Filtering and Color Conversion Medium (CCM) Patterning, alongside advanced material transfer techniques such as Laser-Induced Thermal Imaging (LITI) and Radiation-Induced Sublimation Transfer (RIST). Finally, the text explores next-generation manufacturing tools designed to improve material utilization and throughput, specifically covering the Vapor Injection Source Technology (VIST), the Hot-Wall Method, and the Organic Vapor-Phase Deposition (OVPD) method, all aiming to reduce the high cost associated with OLED materials.
