摘要： The present teachings relate to various embodiments of a gas enclosure system that can have various components comprising a particle control system that can provide a low-particle zone proximal to a substrate. Various components of a particle control system can include a gas circulation and filtration system, a low-particle-generating motion system for moving a printhead assembly relative to a substrate, a service bundle housing exhaust system, and a printhead assembly exhaust system. In addition to maintaining substantially low levels for each species of various reactive species, including various reactive atmospheric gases, such as water vapor and oxygen, for various embodiments of a gas enclosure system that have a particle control system, an on-substrate particle specification can be readily met. Accordingly, processing of various substrates in an inert, low-particle gas environment according to systems and methods of the present teachings can have substantially lower manufacturing defects.

摘要： An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.

摘要： The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.
