Methods and apparatus for minimizing the number of print passes in flat panel display manufacturing

Abstract

A system for inkjet printing includes a first set including a first inkjet print head having a first plurality of nozzles adapted to selectively dispense a first ink, and a second inkjet print head having a second plurality of nozzles adapted to selectively dispense a second ink; a second set including a third inkjet print head having a third plurality of nozzles adapted to selectively dispense a third ink and a fourth inkjet print head having a fourth plurality of nozzles adapted to selectively dispense a fourth ink; and a stage adapted to support the substrate and transport the substrate below the first and second sets during a printing pass; wherein the first set is adapted to dispense the first and second inks into respective adjacent color wells of a display pixel on a substrate and the second set is adapted to dispense the third and fourth inks into respective adjacent color wells of a display pixel on a substrate.
