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 using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen as described above or near the touch screen.

When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the 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 explanation, the action of allowing an object to be recognized as being positioned on the touch screen by being approached without contacting an object on the touch screen is called "proximity touch", and the touch The act of actually touching an object on the screen is referred to as "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object corresponds vertically to the touch screen when the object is touched in proximity.

Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

The photosensor may be stacked on the display device, and the photosensor is configured to scan a motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing object according to the amount of light change, and through this, position information of the sensing object may be obtained.

Referring to FIG. 2A, the display unit 202 may be configured to be deformable by an external force. The deformation may be at least one of bending, bending, folding, twisting, and curling of the display unit 202. Such a deformable display unit 202 may be referred to as a'flexible display unit'. Here, the flexible display unit 202 may include all of a general flexible display, an e-paper, and a combination thereof. In general, the mobile terminal 200 may include features of the mobile terminal 100 of FIGS. 1A to 1C or similar features.

A general flexible display refers to a light and sturdy display that is not easily broken because it is manufactured on a thin and flexible substrate that can be bent, bent, folded, twisted or rolled like paper while maintaining the characteristics of a conventional flat panel display.

In addition, electronic paper is a display technology to which the characteristics of general ink are applied, and the point of using reflected light may be different from the conventional flat panel display. As for the electronic paper, information can be changed by using a twist ball or electrophoresis using a capsule.

In a state in which the flexible display unit 202 is not deformed (eg, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display unit 202 becomes a flat surface. In a state deformed by an external force in the first state (eg, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, information displayed in the second state may be visual information output on a curved surface. This visual information is implemented by independently controlling light emission of sub-pixels arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

In the first state, the flexible display unit 202 may be placed in a curved state (eg, bent vertically or horizontally) rather than a flat state. In this case, when an external force is applied to the flexible display unit 202, the flexible display unit 202 may be deformed into a flat state (or a less curved state) or a more curved state.

Meanwhile, the flexible display unit 202 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the controller 180 (refer to FIG. 1A) may perform a control corresponding to such a touch input. The flexible touch screen may be configured to sense a touch input not only in the first state but also in the second state.

Meanwhile, the mobile terminal 200 according to the present modified example may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 202. Such deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means may be provided in the flexible display unit 202 or the case 201 and may detect information related to deformation of the flexible display unit 202. Here, the information related to the deformation may be a direction in which the flexible display unit 202 is deformed, a deformed degree, a deformed position, a deformed time, and an acceleration at which the deformed flexible display unit 202 is restored, and the like, In addition, it may be various pieces of information that can be detected due to the bend of the flexible display unit 202.

In addition, the controller 180 may change information displayed on the flexible display unit 202 or change the information displayed on the flexible display unit 202 based on information related to the deformation of the flexible display unit 202 detected by the deformation detecting means. It is possible to generate a control signal to control the function of.

Meanwhile, the mobile terminal 200 according to the present modified example may include a case 201 accommodating the flexible display unit 202. The case 201 may be configured to be deformable together with the flexible display unit 202 by an external force in consideration of the characteristics of the flexible display unit 202.

In addition, a battery (not shown) provided in the mobile terminal 200 may also be configured to be deformable together with the flexible display unit 202 by an external force in consideration of the characteristics of the flexible display unit 202. In order to implement the battery, a stack and folding method in which battery cells are stacked on top may be applied.

The state transformation of the flexible display unit 202 is not limited to being caused by an external force. For example, when the flexible display unit 202 has the first state, it may be transformed into the second state by a command of a user or an application.

2B is a conceptual diagram illustrating another example of a deformable mobile terminal 250 according to the present invention.

Referring to FIG. 2B, the display units 251 and 252 may extend to at least one of the left/right side surfaces of the terminal body as well as the front surface of the terminal body. Here, the display unit 251 disposed in front of the terminal body is referred to as a “first display unit (or main display unit)”, and the display units 252a and 252b disposed on at least one of the left and right sides of the terminal body ) Is referred to as a'second display unit (or side display unit)'.

The first and second display units 251 and 252 may be independently disposed on the front and side surfaces of the terminal body, or may be integrally formed and disposed through the flexible display. When implemented integrally through the flexible display, the first display unit 251 and the second display unit 252 may be continuously formed without a physical or spatial boundary.

The first and second display units 251 and 252 may include a touch sensor that senses a touch on the first and second display units 251 and 252 so that a control command can be input by a touch method. . By using this, when a touch is made to the first and second display units 251 and 252, the touch sensor detects the touch, and the controller 180 generates a control command corresponding to the touch based on this. Can be done. Content input by the touch method may be letters or numbers, or menu items that can be indicated or designated in various modes.

The first and second display units 251 and 252 may independently display information processed by the mobile terminal 250. For example, the first display unit 251 displays execution screen information of a first application program driven in the mobile terminal 250, or UI and GUI information according to the execution screen information, and the second display unit 252 ) May display execution screen information of the second application program driven in the mobile terminal 250, or UI and GUI information according to the execution screen information. Meanwhile, as another embodiment, the first and second display units 251 and 252 may integrally display information processed by the mobile terminal 250.

In addition, as another example, the display units 253a and 253b may be additionally disposed on at least one of the upper/lower sides of the terminal body as well as the left/right side of the terminal body. Similarly in this case, the display units 253a and 253b disposed on at least one of the upper and lower sides of the terminal sea sense a touch to the display units 253a and 253b so that a control command can be input by a touch method. It may include a touch sensor. In addition, the display units 253a and 253b may display information processed by the mobile terminal 250 independently of the first and second display units 251 and 252.

Meanwhile, in the present embodiment, although the display unit and the touch sensor are disposed on at least one of the upper/lower/left/right sides of the terminal sea, this is not limited thereto. Therefore, it will be apparent to those skilled in the art that it is possible to design so that only the touch sensor can be disposed without disposing the display unit on at least one of the top/bottom/left/right sides of the terminal sea.

In the above, the configuration of a mobile terminal according to the present invention has been described with reference to FIGS. 1 and 2.
