Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of generating control data for nozzles of a print head to deposit an aggregate volume of ink in at least one target region of a substrate, the aggregate volume to be within a predetermined volume tolerance range, each of the nozzles generating at least one respective droplet volume, the method comprising: receiving information representing the droplet volumes; calculating a combination of droplets for which corresponding droplet volumes sum to a v…
