ABSTRACT:
To increase the perimeter seal strength of plastic LCDs, reinforcement holes are formed in the plastic substrate at the maximum stress points. These holes, which are not in contact with any active area of the device, are filled with glue, so that each pair of holes in the upper and lower substrates forms a tensile connection which directly links the two substrates together at the maximum stress points.
