A touch screen apparatus based on an ultrasonic wave is provided. The touch screen apparatus includes a display, ultrasonic sensors, and a processor. The ultrasonic sensors irradiate ultrasonic signals. The processor, in response to the ultrasonic signals being irradiated from the ultrasonic sensors, reflected from an object touched on the display, and received by the ultrasonic sensors, determines a touch point of the object based on Time of Flights (ToFs) of the received ultrasonic signals.
