Patent ID: 7592044

Claim:
A method for manufacturing a patterned layer on a substrate using at least one print head, comprising the steps of: providing a substrate having a plurality of banks formed thereon, the substrate and the banks cooperatively defining a plurality of accommodating spaces, wherein each of the accommodating spaces has a first edge and a second edge parallel to the first edge, and a distance between the first edge and the second edge is “b;” providing at least one print head comprising a first nozzle and a second nozzle, the first nozzle and the second nozzle being arranged in a nozzle line, the nozzle line being parallel to the substrate; moving the at least one print head along a first path, wherein the first path is slanted relative to the nozzle line, an angle between the nozzle line and the first path is θ, and θ satisfies 0<θ<90°, and wherein the first path is located between the first edge and the second edge of an accommodating space, the first path is parallel to the first edge, and a distance between the first path and the first edge is “a;” jetting ink into the accommodating space from the first nozzle during movement of the at least one print head along the first path; moving the at least one print head along a third path perpendicular to the first path; moving the second nozzle along a second path, wherein the second path is parallel to the first path, a distance between the first path and the second path is “c,” and the distance c satisfies at least one of the two equations: 0<c<b−a, and 0<c<a; jetting ink into the accommodating space from the second nozzle during movement of the at least one print head along the second path; and solidifying the inks in the accommodating space so as to form a patterned layer.
