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.

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.

2 is a conceptual diagram for explaining another example of the mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting unit may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, a battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 due to an external force, taking into account the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
