Latest Patents

Tang holds a patent for "High-resolution shadow masks." This invention involves a shadow mask designed for patterned vapor deposition of OLED materials. The mask features a ceramic membrane under tensile stress, equipped with multiple through-apertures that form an aperture array. This design allows vaporized deposition material to pass through effectively. Additionally, a multilayer peripheral support is attached to the rear surface, with a hollow portion beneath the aperture array. A compressively-stressed interlayer balances the tensile stress of the ceramic membrane. The patent also describes a shadow mask module that includes multiple shadow masks, each positioned within a rigid carrier that has plural windows. The process of creating this module involves affixing shadow mask blanks to each carrier window, followed by etching apertures and support layers. This results in extremely flat masks with precise aperture patterns.
