ABSTRACT:
A liquid crystal which self-generates a high voltage for a high voltage stress test, a connector for testing the liquid crystal display and a method of testing the liquid crystal display include an internal connector having an input pin which receives a power supply voltage from an outside source, a no-connect pin, a ground pin and a power supply unit connected to the no-connect pin and the ground pin. The power supply unit receives the power supply voltage and outputs a gate-on voltage and a gate-off voltage whose levels are adjusted according to whether there is an electrical connection between the no-connect pin and the ground pin. Agate driving unit receives the gate-on voltage and the gate-off voltage and outputs a gate signal and a liquid crystal panel having a plurality of pixels receives the gate signal and displays images in response to the gate signal.
