In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have.

Meanwhile, the controller 180 may calculate the position of the wave generating source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference between the time that the ultrasonic wave arrives using light as the reference signal.

The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the movement of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensor using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target can be obtained.
