Dispensing of liquid with arrays of tubular quill structures

Abstract

A method of dispensing display fluid into an array of cells loads an array of quills with the fluid. inserts the array of quills loaded with the fluid into the array of cells, such that each quill is inserted into a separate cell, contacts an inner surface of the cells to cause the fluid to transfer from the quills to the cells, and seals the cells. A dispensing system has a first substrate having an array of quills arranged on a first pitch, a first fixture to hold the first substrate, a second substrate having an array of cells, wherein the cells are arranged on a second pitch that is proportional to the first pitch, a second fixture to hold the second substrate, and an alignment system to align the first substrate to the second substrate such that each quill dispenses a display fluid into selected ones of the cells. An array of quills reside on a substrate, the quills having a lateral extent less than a lateral dimension of a cell into which the quills will be inserted, and a vertical extent at least twice the vertical extent of a depth of the cells.
