In a display apparatus, a display panel includes touch sensors that make contact with a common electrode by an external pressure to output a common voltage, and a sensing driver receives the common voltage from the touch sensors to generate a sensing signal. A controller receives the sensing signal from the sensing driver and calculates position information to which the external pressure is applied based on the sensing signal. The sensing driver includes a switching circuit that receives a switching signal from the controller to switch the common voltage. Thus, the display apparatus prevents the common voltage from being input during a period where a voltage level of the common voltage is abnormally high, thereby preventing a logic circuit of the sensing driver from being damaged. |
