Abstract: 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.

Abstract: Provided are a low-power ultrasound sensor that detects whether an object exists at a high speed, an object detecting method of the ultrasound sensor, and a computer-readable storage medium. The ultrasound sensor may include: a transmitter that outputs a plurality of first ultrasound beams having different frequencies; a receiver that receives a first reflection signal that is output when the output plurality of first ultrasound beams are reflected from an object; and a controller that determines a first area in a space, controls the transmitter to respectively output the plurality of first ultrasound beams to a plurality of first sub-areas that are included in the first area, and determines whether the object is included in each of the plurality of first sub-areas, based on the first reflection signal.
