Abstract
A method is provided for fabricating a display spacer assembly (100, 400, 500) useful in the fabrication of large-area field emission displays (200, 600). The method includes the steps of: forming slots (12, 22, 32, 33) in a substrate (10, 23, 30) thereby providing a jig; providing spacers (14, 24, 34) having lower rounded edges and upper edges; placing the lower rounded edges into the slots (12, 22, 32, 33) so that the spacers (14, 24, 34) are positioned in a predetermined layout pattern over the slotted jig surface; and placing the upper edges of the spacers (14, 24, 34) in abutting engagement with a display plate (18, 10) of a field emission display.
