Printing bead spacers on flat panel display substrates
First Claim
1. A method for manufacturing an flat panel display, the method comprising:
- spraying a first bead spacer group on a first substrate through a first nozzle group of a head unit;
spraying a second bead spacer group on the first substrate through a second nozzle group of the head unit; and
,coupling a second substrate in spaced opposition to the first substrate.

Abstract
An apparatus for printing bead spacers on a substrate of an LCD panel includes a head unit for spraying a plurality of bead spacer groups on the substrate, a transfer unit for transferring the head unit, and a supply unit for supplying the bead spacers to the head unit. Each of the bead spacer groups includes a plurality of bead spacers, and the sizes of the respective spacers of at least two of the spacer groups are different from each other. The invention enables a cell gap of a substantially uniform thickness to be created and maintained in the panel, prevents the occurrence of smear failures in the panel, and increases the allowable tolerance in the amount of liquid crystal material needed to fill the panel correctly.
