ABSTRACT:
A semiconductor device for driving a liquid crystal panel includes an output unit for generating output signals to drive a liquid crystal panel, a terminal for supplying a voltage from a power supply in the outside of the device, a voltage changing unit connected to the terminal for changing the voltage through the terminal into a voltage necessary for a self burn-in test and for supplying the output unit with the changed voltage, and a control unit for controlling the output unit to conduct the self burn-in test when a predetermined control signal is applied thereto from the outside of the device.
