摘要： The present teachings disclose various embodiments of a printing system for printing substrate, in which the printing system can be housed in a gas enclosure, where the environment within the enclosure can be maintained as a controlled printing environment. A controlled environment of the present teachings can include control of the type of gas environment within the gas enclosure, the size and level particulate matter within the enclosure, control of the temperature within the enclosure and control of lighting. Various embodiments of a printing system of the present teachings can include a Y-axis motion system and a Z-axis moving plate that are configured to substantially decrease excess thermal load within the enclosure by, for example, eliminating or substantially minimizing the use of conventional electric motors.

摘要： 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.

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.

摘要： The present teachings relate to various embodiments of an hermetically-sealed gas enclosure assembly and system that can be readily transportable and assemblable and provide for maintaining a minimum inert gas volume and maximal access to various devices and apparatuses enclosed therein. Various embodiments of an hermetically-sealed gas enclosure assembly and system of the present teachings can have a gas enclosure assembly constructed in a fashion that minimizes the internal volume of a gas enclosure assembly, and at the same time optimizes the working space to accommodate a variety of footprints of various OLED printing systems. Various embodiments of a gas enclosure assembly so constructed additionally provide ready access to the interior of a gas enclosure assembly from the exterior during processing and readily access to the interior for maintenance, while minimizing downtime.

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： Apparatus and techniques are described herein for use in manufacturing electronic devices. such as can include organic light emitting diode (OLED) devices. Such apparatus and techniques can include using one or more modules having a controlled environment. For example, a substrate can be received from a printing system located in a first processing environment, and the substrate can be provided a second processing environment, such as to an enclosed thermal treatment module comprising a controlled second processing environment. The second processing environment can include a purified gas environment having a different composition than the first processing environment.
