Abstract:
An apparatus and method for liquid-phase dispensing of layers onto a substrate of an electronic device. An absorbent material reduces or eliminates splatter of printing material on the substrate during continuous printing operations. The absorbent material can be regenerated by exposure of new surface area or vacuum drawing of printing material through the absorbent material.

A printing head has z nozzles arranged in a row with a spacing p, where z = n1(c) and p = (c-1)(s), the printhead being at a first position relative to the workpiece. There are c different printing inks, one for each of the c colors, and each of the printing inks is supplied to the nozzles in a regular alternating pattern. The method includes steps of printing a first set of z rows of subpixels with the printing head; moving the workpiece laterally relative to the printing head by a distance d1, where d1 = z(s); printing a second set of z rows of subpixels with the printing head; repeating the printing steps n2 times for a total of n2 + 2 sets of z rows of subpixels. Variables include: c, an integer greater than 1; n1, an integer greater than 0, with the proviso that when c is an odd number, then n1 is an odd number; and n2, an integer greater than 0.
