Patent number: 11203207Abstract: Improved manufacturing using a printer that deposits a liquid to fabricate a layer having specified thickness includes automated adjustment or print parameters based on ink or substrate characteristics which have been specifically measured or estimated. In one embodiment, ink spreading characteristics are used to select droplet size used to produce a particular layer, and/or to select a specific baseline volume/area or droplet density that is then scaled and/or adjusted to provide for layer homogeneity. In a second embodiment, expected per-droplet particulars are used to interleave droplets in order to carefully control melding of deposited droplets, and so assist with layer homogeneity. The liquid layer is then cured or baked to provide for a permanent structure.Type: GrantFiled: December 2, 2016Date of Patent: December 21, 2021Assignee: KATEEVA, INC.Inventors: Conor F.

TECHNIQUES FOR PRINT INK DROPLET MEASUREMENT AND CONTROL TO DEPOSIT FLUIDS WITHIN PRECISE TOLERANCES
Publication number: 20210167339Abstract: 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.Type: ApplicationFiled: February 10, 2021Publication date: June 3, 2021Applicant: Kateeva, Inc.Inventors: Nahid Harjee, Lucas D.

Publication number: 20210040595Abstract: 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.Type: ApplicationFiled: October 28, 2020Publication date: February 11, 2021Applicant: Kateeva, Inc.Inventors: Sass Somekh, Eliyahu Vronsky, Conor F.
