Patent ID: 7647959

Claim:
A liquid crystal display (LCD) bonding machine comprising: a one piece bonding chamber for carrying out bonding of first and second substrates, the first substrate having liquid crystal dispensed thereon and the second substrate having sealant coated thereon; an upper stage and a lower stage within the one piece bonding chamber, the upper stage holding the second substrate and the lower stage holding the first substrate a substrate receiver for receiving the second substrate which was held on the upper stage, the substrate receiver supporting a central part of the second substrate in the non-active region, rather than supporting only the corner parts of the second substrate; at least two air outlets for evacuating an interior of the bonding chamber; and at least two vacuum means for evacuating the bonding chamber, at least one vent hole in communication with the bonding chamber for introducing air or gas into an interior of the bonding chamber; and a gas supply means connected to the at least one vent hole for supplying air or gas into the interior of the bonding chamber, wherein the at least two vacuum means include a turbo molecular pump connected to an air outlet and at least two dry pumps, the turbo molecular pump generating a greater vacuum than the at least two dry pumps connected to an air outlet different from the turbo molecular pump.
