摘要:
A test apparatus for a Liquid Crystal Display (LCD) device receives a mode input signal representing whether the LCD device is driven in a normal voltage driving mode or a high voltage driving mode. The test apparatus transmits a voltage to the LCD device and transmits a control signal to a high voltage applying module, which turns on to transmit a high voltage to the LCD device or turns off according to a level of the control signal. The LCD device may remain coupled with the high voltage applying module while the LCD device operation is shifted between a high voltage driving mode and a normal voltage driving mode during a manufacturing process thereof, so manufacturing time for the LCD device may be reduced.
