On the other hand, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control the driving or operation of the mobile terminal 100 or perform data processing, function, or operation related to an application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an electric field according to the proximity of the 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 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.) there is. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. It can be printed on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. .

The touch sensor detects a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. do.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, an electrostatic capacitance at the time of touch, etc. in which a touch object applying a touch on the touch screen is touched on the touch sensor. 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, a stylus pen, or a pointer.

As such, when there is a touch input to the touch sensor, a signal(s) corresponding thereto is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180 . Accordingly, the controller 180 can know which area of the display unit 151 has been touched, and the like. Here, the touch controller may be a component separate from the controller 180 , or may be the controller 180 itself.

The ultrasonic sensor may recognize position information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave 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 at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference from the time that the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the motion 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 sensors 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.

For example, when the adjustment key 500 is in the non-adjusted position, the second body 200b may move from the first position to the second position. At this time, since the reference line RL may pass through the second sensor 144 , the second sensor 144 detects the magnet 510 of the adjustment key 500 . However, since the fifth sensor 147 detects the movement of the second body 200b, the controller 180 controls so that the second adjustment is not made, and accordingly, the volume is not lowered. (FIG. 13A) Reference)

As another example, when the adjustment key 500 is in the non-adjustment position, the second body 200b may move from the second position to the first position. At this time, since the reference line RL may pass through the third sensor 145 , the third sensor 145 detects the magnet 510 of the adjustment key 500 . However, since the fifth sensor 147 detects the movement of the second body 200b, the controller 180 controls so that the first adjustment is not made, and accordingly, the volume is not increased (FIG. 13B).

elastic bodies

elastic bodies

550 and 560 may be made of various materials, shapes, and structures within the range in which elastic deformation is made. The elastic body may be formed of a metal spring. The elastic body may be formed of a leaf spring, a spiral spring, a torsion spring, or a coil spring.

The elastic body (550, 560) coupled to the second body (200b) is made to elastically support the adjustment key (500). When the external force is applied to the control key 500 and the control key 500 moves against the second body 200b and then the external force is removed, the

elastic bodies

550 and 560 move the control key 500 to the original position. Elastically support the adjustment key (500).

However, the elastic deformation of the first elastic body 550 and the second elastic body 560 may be opposite to each other. For example, when the elastic deformation of the first elastic body 550 increases, the elastic deformation of the second elastic body 560 may decrease, and when the elastic deformation of the first elastic body 550 decreases, the elastic deformation of the second elastic body 560 is decreased. Elastic deformation may increase.

When a separate external force does not act, the first elastic body 550 and the second elastic body 560 may elastically support the adjustment key 500 so that the adjustment key 500 is positioned at a non-adjustable position. That is, when the adjustment key 500 is in the non-adjusted position, the elastic force applied by the first elastic body 550 to the adjustment key 500 and the elastic force applied by the second elastic body 560 to the adjustment key 500 are opposite to each other. It works as a balance

In one embodiment, the direction connecting the N pole and the S pole of the magnet 510 of the adjustment key 500 is made to be orthogonal to the first direction (X). For example, the direction connecting the N pole and the S pole of the magnet 510 of the adjustment key 500 may be made parallel to the second direction Y, and may be made the same as the reference line RL.

The flexible display device 1 is controlled to increase this (refer to FIG. 14B).

When the external force applied to the adjustment key 500 is removed, the adjustment key 500 moves to the non-adjusted position again, and the first sensor 143 does not detect the magnet 510 of the adjustment key 500, but increases the volume (first adjustment) is suspended.
