Abstract: An inkjet printer is described. The inkjet printer has a substrate holder assembly that includes a base member having a long axis in a first direction and a short axis in a second direction perpendicular to the first direction; a contact member coupled to the base member, the contact member having a long axis in the first direction and a short axis in the second direction; a holder carriage coupled to the base member; a linear extender coupled between the base member and the contact member and extending in a third direction intersecting with the first direction and the second direction from the base member toward the contact member; and a flex member coupled to the base member, extending in the second direction between the linear extender and the contact member, and having a flex direction in a direction perpendicular to the first direction and the second direction.

Abstract: A printer deposits material onto a substrate as part of a manufacturing process for an electronic product. At least one mechanical component experiences mechanical error, which is mitigated using transducers that equalize position of a transported thing, e.g., to provide an “ideal” conveyance path; a substrate conveyance system and/or a printhead conveyance system can each use transducers in this manner to improve precise droplet placement. In one embodiment, errors are measured in advance, with corrections being “played back” during production runs to mitigate repeatable transport path error. In a still more detailed embodiment, the transducers can be predicated on voice coils, which cooperate with a floatation table and floating, mechanical pivot assembly to provide frictionless, but mechanically-supported error correction.

Abstract: The present teachings relate to various embodiments of a gas enclosure system that can have a particle control system that can include a multi-zone gas circulation and filtration system, a low-particle-generating X-axis linear bearing system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. Various components of a particle control system can include a tunnel circulation and filtration system that can be in flow communication with bridge circulation and filtration system. Various embodiments of a tunnel circulation and filtration system can provide cross-flow circulation and filtration of gas about a floatation table of a printing system. Various embodiments of a gas enclosure system can have a bridge circulation and filtration system that can provide circulation and filtration of gas about a printing system bridge and related apparatuses and devices. Accordingly, various embodiments of a gas circulation and filtration system as disclosed herein can effectively remove both airborne particulate matter, as well as particulate matter generated proximal to a substrate during a printing process. As such, various embodiments of a gas circulation and filtration system in conjunction with various embodiments of a gas purification system of the present teachings can provide for a controlled manufacturing environment resulting in a high-yield of OLED various devices.

Abstract: A system may include a support surface for supporting a substrate, a plurality of first passages arranged to distribute flows of a first gas to establish a gas bearing to float the substrate above the support surface, and a plurality of second passages arranged to distribute flows of a second gas to convey the substrate along the support surface. A method may include floating a substrate above a support surface of a substrate support apparatus via a gas bearing; and while floating the substrate, conveying the substrate along the support surface by flowing gas toward a surface of the substrate and in a nonperpendicular direction relative to the surface of the substrate.

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.
