Printing bead spacers on flat panel display substrates
First Claim
1. A liquid crystal display (LCD) comprising:
- a first substrate;
a second substrate facing the first substrate;
a light blocking member disposed on the second substrate;
a plurality of first bead spacers and a plurality of second bead spacers disposed between the first substrate and the second substrate,wherein the first bead spacers have a different size from that of the second bead spacers, andwherein the first and the second bead spacers are disposed in a region correspond to the light blocking member.

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.
