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: 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。

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 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.
