The touch sensor may be configured to detect not only the position and area where the touch object is touched on the touch sensor, but also the pressure at the time of the touch. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits corresponding data to the controller 180. Accordingly, the control unit 180 can know which area of the display unit 151 has been touched, and the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of a mobile terminal surrounded by the touch screen or near the touch screen.

The proximity sensor 141 measures a distance between a sensing target (eg, a user's finger or a stylus pen) and a detection surface that applies a touch without mechanical contact using an electromagnetic field force or infrared rays. The terminal uses this distance to recognize which part of the stereoscopic image has been touched. In particular, when the touch screen is a capacitive type, it is configured to detect the degree of proximity of the detection object by changing the electric field according to the proximity of the detection object, and to recognize a 3D touch using the proximity degree.

The three-dimensional touch sensing unit 142 is configured to sense the intensity or duration of a touch applied on the touch screen. For example, the three-dimensional touch sensing unit 142 senses the pressure applied to the touch, and when the pressing force is strong, recognizes it as a touch on an object located farther from the touch screen toward the interior of the terminal.

The ultrasonic sensing unit 143 is configured to recognize location information of a sensing target using ultrasonic waves.

The ultrasonic sensing unit 143 may be formed of, for example, an optical sensor and a plurality of ultrasonic sensors. The optical sensor is configured to sense light, and the ultrasonic sensor is configured to detect ultrasound. Since light is much faster than ultrasound, the time for light to reach the optical sensor is much faster than the time for ultrasound to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source by using the time difference from the time that the ultrasound reaches the light as a reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. When distance information detected by a laser sensor is added to a 2D image photographed by a camera, 3D information may be obtained.

As another example, a photo sensor may be stacked on the display element. The photo sensor 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 thereby acquires the position information of the sensing target.
