When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object with a change in electric field according to the proximity of the conductive object. 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 allowing the object to be recognized as being located on the touch screen without being touched on the touch screen is called a "proximity touch", and the touch The act of actually touching an object on the screen is called "contact touch". The location where an object is touched close on the touch screen refers to a location where the object is perpendicular to the touch screen when the object is touched close. 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, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141, and further, visual information corresponding to the processed data.

Accordingly, the control unit 180 can know which area of the display unit 151 has been touched, and the like. Here, the touch controller may be a separate component from the controller 180, or may be the controller 180 itself.

Meanwhile, the control unit 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 generator can be calculated by using a property in which light is much faster than ultrasonic waves, that is, a time when light reaches the optical sensor is much faster than a time when ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave generating source may be calculated by using a time difference from the time at which ultrasonic waves reach the light as a reference signal.

The photo sensor may be stacked on a display element, which is configured to scan the movement of the sensing object close to the touch screen. More specifically, the photo sensor mounts photo diodes and TRs (transistors) in rows/columns to scan the contents loaded on the photo sensor using electrical signals that change according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the sensing target according to the amount of change of light, and through this, location information of the sensing target may be obtained.
