Abstract: A drop placement analyzer for an inkjet printer is described herein. The drop placement analyzer comprises a film support that has an opaque, optically non-interfering vacuum surface for immobilizing a film against the optically non-interfering vacuum surface and photographing drops disposed on the film from the same side of the film on which the drops are disposed.

Abstract: A coating can be provided on a substrate. Fabrication of the coating can include forming a solid layer in a specified region of the substrate while supporting the substrate in a coating system using a gas cushion. For example, a liquid coating can be printed over the specified region while the substrate is supported by the gas cushion. The substrate can be held for a specified duration after the printing the patterned liquid. The substrate can be conveyed to a treatment zone while supported using the gas cushion. The liquid coating can be treated to provide the solid layer including continuing to support the substrate using the gas cushion.

Abstract: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different printhead/substrate scan offsets, offsets between printheads, the use of different nozzle drive waveforms, and/or other techniques. These combinations can be based on repeated, rapid droplet measurements that develop understandings for each nozzle of means and spreads for expected droplet volume, velocity and trajectory, with combinations of droplets being planned based on these statistical parameters. Optionally, random fill variation can be introduced so as to mitigate Mura effects in a finished display device. The disclosed techniques have many possible applications.

Abstract: Apparatus and techniques for use in manufacturing a light emitting device, such as an organic light emitting diode (OLED) device can include using one or more modules having a controlled environment. The controlled environment can be maintained at a pressure at about atmospheric pressure or above atmospheric pressure. The modules can be arranged to provide various processing regions and to facilitate printing or otherwise depositing one or more patterned organic layers of an OLED device, such as an organic encapsulation layer (OEL) of an OLED device. In an example, uniform support for a substrate can be provided at least in part using a gas cushion, such as during one or more of a printing, holding, or curing operation comprising an OEL fabrication process. In another example, uniform support for the substrate can be provided using a distributed vacuum region, such as provided by a porous medium.
Abstract translation: 用于制造发光器件（例如有机发光二极管（OLED））器件的装置和技术可以包括使用具有受控环境的一个或多个模块。 受控环境可以保持在大气压或大气压以上的压力。 这些模块可以被布置成提供各种处理区域并且便于打印或以其他方式沉积OLED器件（例如OLED器件的有机封装层（OEL））的一个或多个图案化的有机层。 在一个示例中，可以至少部分地使用气垫来提供对基底的均匀支撑，例如在包括OEL制造工艺的一个或多个印刷，保持或固化操作期间。 在另一个实例中，可以使用诸如由多孔介质提供的分布式真空区域来提供对基底的均匀支撑。

Abstract: A printer includes a substrate support, a printhead assembly, first and second actuators, and a controller. The printhead assembly deposits material on a substrate supported on the substrate support. The first actuator is disposed at a side of the substrate support and coupled to a first linear track disposed along the side of the substrate support and oriented in a first direction. The second actuator is disposed at an end of the substrate support and coupled to a second linear track disposed along the end of the substrate support and oriented in a second direction perpendicular to the first direction. The first and second actuators are positioned to engage with the substrate simultaneously. The controller moves the first and second actuators together to rotate the substrate.

Abstract: A method of forming a material layer on a substrate comprises loading a substrate into a printing zone of a coating system using a substrate handler, printing an organic ink material on a substrate while the substrate is located in the printing zone, transferring the substrate from the printing zone to a treatment zone of the coating system, treating the organic ink material deposited on the substrate in the treatment zone to form a film layer on the substrate, and removing the substrate from the treatment zone using the substrate handler.
