43.3: Slot Die Coating for OLED Displays
暂无分享,去创建一个
Slot die coating is a cost-effective, scalable process for applying continuous organic layers in OLED displays. Uniform submicron coatings can be obtained on patterned OLED backplanes from low viscosity fluids. Coating and drying defects can be reduced by adjusting fluid properties, e.g., surface tension, viscosity and concentration.
