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: A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display.

Abstract: 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.

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: 使用喷墨工艺将材料层沉积到期望的厚度。 布局数据被转换为每单元格灰度值，每个值表示要本地传送的墨水量。 灰度值用于产生半色调图案，以将可变墨水体积（和厚度）输送到基底。 半色调提供相对连续的层（例如，没有非预期的间隙或孔），同时提供可变体积，并因此有助于可变的油墨/材料积聚以实现期望的厚度。 油墨被喷射成液体或气溶胶，其悬挂用于形成材料层的材料，例如用于形成平板装置的封装层的有机材料。 然后将沉积层固化或以其它方式完成以完成该过程。
