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印刷或以其它方式沉积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 inkjet printer is described herein that has a substrate staging portion with a discontinuous gas float system comprising a plurality of gas float members separated by gaps. The gaps enable interoperation with an end effector to deposit and retrieve substrates on a gas cushion provided by the gas float members.

Abstract: A method for providing a substrate coating comprises transferring a substrate to an enclosed ink jet printing system; printing organic material in a deposition region of the substrate using the enclosed ink jet printing system, the deposition region comprising at least a portion of an active region of a light-emitting device on the substrate; loading the substrate with the organic material deposited thereon to an enclosed curing module; supporting the substrate in the enclosed curing module, the supporting the substrate comprising floating the substrate on a gas cushion established by a floatation support apparatus; and while supporting the substrate in the enclosed curing module, curing the organic material deposited on the substrate to form an organic film layer.

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 translation: 油墨印刷工艺采用每喷嘴液滴体积测量和处理软件，其计划液滴组合以达到每个目标区域的特定聚集油墨填充，从而保证符合规格设定的最小和最大油墨填充量。 在各种实施例中，通过不同的打印头/衬底扫描偏移，打印头之间的偏移，使用不同喷嘴驱动波形和/或其他技术来产生不同的液滴组合。 这些组合可以基于重复的快速液滴测量，其基于这些统计参数来计算液滴的组合，从而为每个喷嘴的装置和预期的液滴体积，速度和轨迹展开了理解。 可选地，可以引入随机填充变化，以便减轻完成的显示设备中的Mura效应。 所公开的技术具有许多可能的应用。
