MULTICOLOR ELECTRONIC DEVICES AND PROCESSES OF FORMING THE SAME BY PRINTING

Document Type and Number:

WIPO Patent Application WO/2010/141699

Kind Code:

A3

Abstract:

There is provided a process of forming a regular array of rows of subpixels on a workpiece. The subpixels having 3 different colors, and a subpixel pitch s. Of the three colors, q colors are formed by printing and r colors are formed by a non-printing method. The process includes the steps: (1) providing a printing head having z nozzles arranged in a row with a spacing between the nozzles of p, where z = 3n1 and p = 2s, the printhead being at a first position relative to the workpiece; (2) providing q different printing inks, one for each of the q printed colors; (3) supplying each of the printing inks to the nozzles in a regular alternating pattern; (4) printing a first set of z rows of subpixels with the printing head; (5) moving and printing in a first pattern with the steps: (a) moving the workpiece laterally relative to the printing head by a distance d1, where d1 = 3n2; and (b) printing a set of z rows of subpixels with the printing head; (6) moving and printing in a second pattern with the steps: (c) moving the workpiece laterally relative to the printing head by a distance d2, where d2 = 3n3, such that d1 + d2 = pz; and (d) printing a set of z rows of subpixels with the printing head; (7) repeating steps (5) and (6) multiple times in the same order; and (8) applying r colors by a non-printing method. Variables include: n1, an integer greater than 0; n2 and n3, odd integers, such that n2 + n3 = 2n1 q, an integer from 1 -3; and r, an integer, such that q + r = 3.
