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 manufacturing an electronic display screen having an array of pixels, the method employing a printhead having nozzles that eject droplets of a liquid onto a substrate, the liquid carrying a material that is to form a permanent layer of the electronic display screen, the method comprising: for each nozzle of the printhead, receiving an expected volume for a droplet of the liquid produced by the nozzle in response to a nozzle drive waveform appli…
