The voltage induction pattern is formed on the substrate adjacent to the voltage-applying pattern, and is spaced apart from the voltage-applying pattern to sense an induced voltage corresponding to the driving voltage. The induced voltage is induced by the voltage-applying pattern. The protection part detects the induced voltage to control the driving voltage output by the voltage transformer.	06-25-2009

20090115956	DEVICE FOR COOLING LCD PANEL AND HEAT TREATMENT APPARATUS HAVING THE SAME - A heat treatment apparatus for manufacturing a liquid crystal display panel through an in-situ process includes a body and a hardening unit, an annealing unit, and a transferring unit disposed on the body. The hardening unit heats a sealing member within a liquid crystal display panel to harden the sealing member. The annealing unit anneals liquid crystal within the liquid crystal display panel sealed by the sealing member. The transferring unit transfers the liquid crystal display panel between the hardening unit and the annealing unit. Therefore, the sealing member may be hardened and the liquid crystal may be sealed through an in-situ process to enhance productivity.	05-07-2009
