A gate-off voltage generator provides a gate-off voltage to a gate line of a display panel. The gate-off voltage generator includes a transistor having a base terminal, a collector terminal, and an emitter terminal, the emitter terminal configured to output the gate-off voltage to the gate line. A controller is connected to the base terminal. A feedback circuit is connected between the gate line and the controller, the feedback circuit configured to provide to the controller a feedback voltage based upon the gate-off voltage outputted from the emitter terminal. The gate-off voltage from the emitter terminal is compared with a desired gate-off voltage in the controller and the voltage at the base terminal is controlled by the controller to provide the desired gate-off voltage to gate line.

A power source circuit of a display apparatus includes a voltage divider, an operational amplifier, a first switch, a second switch, and a protector. The voltage divider generates a divided voltage between a first driving voltage and a ground voltage. The operational amplifier receives the divided voltage and outputs the divided voltage as a second driving voltage. The first switch is connected between a first supply voltage terminal to receive the first driving voltage and a common node. The second switch is connected between the common node and a second supply voltage terminal to receive the ground voltage. The protector is connected to the common node to limit a voltage output of the first supply voltage terminal in response to a voltage of the common node.
