Apparatus for applying OFF-state stress to P-MOS device

A method for applying an OFF-state stress to a P-MOS device of a liquid crystal display (LCD) device, comprising:

• loading a plurality of array substrates for an LCD device into a plurality of jigs, each of said array substrates having a gate line, a data line, and a common line;
• applying a source power from a power supply unit to the gate line, data line, and common line of a plurality of the array substrates loaded into the jigs;
• modulating the source power voltage of the gate line, data line, and common line of each of the plurality of array substrates via a voltage control unit;
• and
• modulating the frequency of an AC voltage component of the voltage-modulated source power via a frequency control unit.

A liquid crystal display (LCD) device loading unit comprises:

• at least one panel jig for holding a LCD device, said LCD having a gate pad, data pad, common pad, and at least one P-MOS device;
• said panel jig including first, second and third power input terminals;
• said first power input terminal corresponding to said gate pad, said second power input terminal corresponding to said data pad, and said third power input terminal corresponding to said common pad;
• said first, second, and third power input terminals contacting said gate, data, and common pads, respectively, when said LCD device is loaded into said panel jig;
• and
• said panel jig supplying an OFF-state stress to said P-MOS device of said LCD device via said first, second, and third power input terminals and said gate, data, and common pads.
