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 print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

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: A coating can be provided on a substrate. Fabrication of the coating can include forming a solid layer in a specified region of the substrate while supporting the substrate in a coating system using a gas cushion. For example, a liquid coating can be printed over the specified region while the substrate is supported by the gas cushion. The substrate can be held for a specified duration after the printing the patterned liquid. The substrate can be conveyed to a treatment zone while supported using the gas cushion. The liquid coating can be treated to provide the solid layer including continuing to support the substrate using the gas cushion.

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.
