The short range communication module 114 may detect (or recognize) a wearable device capable of communicating with the mobile terminal 100 around the mobile terminal 100.

Meanwhile, 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 corresponding sensing signal. The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the 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 of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by 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 proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 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 output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when 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 transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Meanwhile, the touch sensor may be configured to detect the touch input using different methods in the activated and deactivated states of the display unit 151. [ At this time, the different method may be related to the activation period of the touch sensor. More specifically, the touch sensor may be activated at different periods depending on whether the display unit 151 is activated or not. That is, the touch sensor can detect the touch input applied to the touch sensor with different activation periods depending on whether the display unit 151 is activated or not.

For example, in a state in which the display unit 151 is inactivated, the touch sensor may be activated at a predetermined period. In this case, the specific period may be a period corresponding to a time greater than zero. In a state in which the display unit 151 is activated, the touch sensor can be always operated in an activated state. That is, in this case, the activation period of the touch sensor may be 0 or a period having a time very close to 0.

The activation of the touch sensor can be distinguished by using the power consumption of the touch sensor. For example, if the power consumption of the touch sensor is less than a predetermined reference value based on 0, the touch sensor is in a deactivated state, and if the power consumption of the touch sensor is greater than the predetermined reference value , It can be said that it is activated.

 When the display unit 151 is in an active mode (hereinafter referred to as an 'active mode'), the touch sensor continues to be in an active state and can wait for the touch input to the display unit 151 have. Alternatively, when the display unit 151 is in a deactivated state (referred to as a 'doze mode' hereinafter), the touch sensor may be activated every predetermined period.

On the other hand, the shorter the specific period in which the touch sensor is activated, the faster the touch input sensing the touch of the display unit 151 is, but the power consumed by the touch sensor can be increased accordingly. In contrast, the longer the period in which the touch sensor is activated, the smaller the power consumed by the touch sensor, but the speed at which the touch input to tap the display unit 151 may be slowed down.

Therefore, the specific period can be set so as to increase the efficiency of power consumption while sensing the touch input that hits the display unit 151, such that the sensing speed is not recognized by the user. For example, a specific period may be set such that the touch sensor is inactivated and activated about 20 times per second (1 Hz).

Meanwhile, during the activated state of the display unit 151, the touch sensor may also be activated. In the activated state, the activation period T of the touch sensor may be zero or very close to zero. Alternatively, in a state in which the touch sensor is activated, the period of the touch sensor may be several times shorter than the specific period in which the touch sensor is activated in a state in which the display unit 151 is inactivated. That is, the touch sensor can be activated at different periods depending on whether the display unit 151 is activated or not.

On the other hand, in the doze mode in which the display unit 151 is inactivated and the touch sensor is periodically activated, a predetermined touch input by the touch sensor (for example, The controller 180 may switch the doze mode to an active mode in which the display unit and the touch sensor are activated.

In addition, the touch sensors can be driven at different periods based on the state of the display unit 151. [ For example, when the display unit 151 is in the closed state, the doze mode is executed, and when the display unit 151 is switched from the closed state to the open state, the active mode can be executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100.
