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 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 located on the touch screen without being in contact with the object to be recognized as being positioned on the touch screen is named "proximity touch", and the touch The act of actually touching an object on the screen is called "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding 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, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data.

The touch sensor may be configured to detect a position, an area, and a pressure at the time of a touch on the touch sensor by a touch object applying a touch on the touch screen. 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.

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

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to the touch screen).

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. 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.

Meanwhile, the camera 121 is a type of camera sensor, viewed as the configuration of the input unit 120, and the camera sensor includes at least one of a camera 121, a photo sensor, and a laser sensor.

The photosensor may be stacked on the display device, and the photosensor is configured to scan the 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.

The rear input unit may be implemented in a form capable of inputting by a touch input, a push input, or a combination thereof.

The rear input unit may be disposed to overlap the display unit 151 on the front surface in the thickness direction of the terminal body. For example, when the user holds the terminal body with one hand, the rear input unit may be disposed on the rear upper end of the terminal body so that the user can easily manipulate the terminal body using the index finger. However, the present invention is not necessarily limited thereto, and the position of the rear input unit may be changed.

When the rear input unit is provided on the rear side of the terminal body, a new type of user interface can be implemented using the rear input unit. In addition, by replacing at least some of the functions of the first operation units 123a and 123b provided on the front of the terminal body with the touch screen or the rear input unit described above, the first operation units 123a and 123b are not installed on the front of the terminal body. When disposed, the display unit 151 may be configured as a larger screen.

The wireless charging may be implemented by a magnetic induction method or a resonance method (magnetic resonance method).

On the other hand, in this drawing, the rear cover 103 is coupled to the rear case 102 to cover the battery 191 to limit the separation of the battery 191 and protect the battery 191 from external shocks and foreign substances. It is exemplifying. When the battery 191 is configured to be detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

Meanwhile, the display unit 151 of the present invention is formed in a curved shape along one direction of the terminal body, and is hereinafter referred to as a curved display unit 151.

In this embodiment, it is illustrated that the curved display unit 151 is formed to be bent along the length direction L of the terminal body. That is, both ends of the curved display unit 151 in which the first sound output unit 152a and the microphone 122 are disposed respectively have a shape bent with respect to the central portion. Alternatively, the curved display unit 151 may be formed to be curved along the width direction W of the terminal body.

The mobile terminal 100 may be formed in a curved shape as a whole, in addition to the curved display unit 151 having a curved shape.

Also, the window 151a may cover the side surface of the mobile terminal.

Hereinafter, a mechanism structure centered on the curved display unit 151 will be described in more detail with reference to the accompanying drawings.

4 is a conceptual diagram illustrating another example of a deformable 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 bending, bending, folding, twisting, and curling of the display unit 251. Such a deformable display unit 251 may be referred to as a “flexible display unit”. Here, the flexible display unit 251 may include all of a general flexible display, e-paper, and combinations thereof. In general, the mobile terminal 200 may include features of the mobile terminal 100 of FIGS. 1 to 3 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 characteristics of general inks are applied, and the point of using reflected light may be different from conventional flat panel displays. Electronic paper can change information by using a twist ball or electrophoresis using a capsule.

In a state in which the flexible display unit 251 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 251 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, the information displayed in the second state may be visual information output on a curved surface. Such 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 251 may be placed in a curved state (eg, a vertically or horizontally curved state) rather than a flat state. In this case, when an external force is applied to the flexible display unit 251, the flexible display unit 251 may be deformed into a flat state (or less curved state) or a more curved 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 controller 180 (refer to FIG. 1) 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 251. Such deformation detecting means may be included in the sensing unit 140 (see FIG. 1).

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

In addition, the controller 180 may change information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on information related to the deformation of the flexible display unit 251 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 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) provided in the mobile terminal 200 may also 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 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 251 is not limited to being caused by an external force. For example, when the flexible display unit 251 has a first state, it may be transformed into a second state by a command of a user or an application.

5 is a conceptual diagram showing a state in which the touch pattern unit 310 according to the present invention is attached to the carrier film 301.

The touch pattern part 310 of the present invention is provided by being attached to the carrier film 301 before being transferred to the window of the mobile terminal. The carrier film 301 may include and attach a touch pattern part 310, a signal transmission part 312, and a flexible circuit board connection part 314.

When referring to the enlarged view of the drawing, the touch pattern unit 310 may form a mesh-shaped mesh. The touch pattern part 310 may be made of a metal material of a soft material to be stretched or contracted in response to the bending of the window 151a. In the present invention, the touch pattern part 310 may mean a metal mesh. Since the touch pattern part 310 can be stretched or contracted by a certain amount, the risk of damage is reduced as it is stretched or contracted in correspondence with the window 151a formed into a curved surface.

The touch pattern part 310 is disposed so that the metal meshes in the diagonal direction are alternated with each other. The metal mesh may include an X-axis etching line 303 etched at a predetermined distance in the X-axis direction and a Y-axis etching line 304 etched at a predetermined distance in the Y-axis direction. Due to the X-axis etching line 303 and the Y-axis etching line 304, the touch pattern part 310 is formed into a small square. The square is formed to be smaller than an area (approximately 6 to 7 mm) touched when the user touches the window 151a, and may be formed so that the user can grasp which point the user touched. Preferably, the length of one side of the square is about 5 mm.

Unlike the above description, only one of the X-axis etching line 303 and the Y-axis etching line 304 may be formed in the touch pattern part 310. This will be described in detail later in the description of FIG. 9.

Preferably, the thickness of one strand of the metal mesh may be about 2 μm (micrometer), and the distance between the metal meshes may be about 200 to 300 μm (micrometer). The angle formed by the metal meshes that are alternately arranged may be changed according to pixel information of the display unit 151.

The signal transmission unit 312 is electrically connected to the touch pattern unit 310 at both sides of the touch pattern unit 310 to form a signal transmission path.

The signal transmission unit 312 is made of a conductive material to reduce resistance, and may be densely disposed to be colored. As the signal transmission unit 312 is colored, the signal transmission unit may be disposed on a bezel of the mobile terminal.

The signal transmission part 312 and the touch pattern part 310 may be made of the same material. However, the touch pattern portions 310 may be disposed to be spaced apart from each other to ensure transparency.

In the upper portion 313 of the signal transmission unit, the signal transmission unit 312 may be arranged in a bent shape in order to collect signals of the signal transmission units 312 disposed on both sides of the touch pattern unit 310.

The signal transmission unit 312 may include a flexible circuit board connection unit 314 electrically connected to the flexible circuit board. The flexible circuit board connection part 314 may be formed at one end of the signal transmission part 312, and the flexible circuit board connection parts 314 formed for each signal transmission path may be assembled to form a terminal part.

In addition, the present invention relates to a terminal body, a window 151a mounted on one surface of the terminal body, and a touch pattern part transferred to the rear surface of the window 151a (see FIGS. Including 310, the touch pattern part 310 forms a mesh in the form of a mesh, and includes a mobile terminal made of a metal member of a soft material to be stretched or contracted in response to the bending of the window 151a. Can be formed.

6 is a flowchart illustrating a method of manufacturing a curved window 151a of a mobile terminal according to the present invention.

A method of manufacturing a curved window 151a of a mobile terminal according to an embodiment of the present invention includes attaching a touch pattern part 310 forming a signal transmission path to a carrier film 301, the touch pattern part 310 ) To face one surface of the window 151a of the mobile terminal, disposing the carrier film 301 on one surface of the window 151a, pressing or heating the carrier film 301, and the touch pattern part Transferring 310 to the window 151a, removing the carrier film 301 from the window 151a, and pressing the window 151a to transfer the touch pattern 310 And transforming the window 151a to have a curved shape.

Attaching the touch pattern part 310 forming a signal transmission path to the carrier film 301 is a step of attaching the touch pattern part 310 to the carrier film 301. In the above step, a signal transmission path and a flexible circuit board connection part 314 may be attached to the carrier film 301 in addition to the touch pattern part 310.

The step of disposing the carrier film 301 on one surface of the window 151a so that the touch pattern part 310 faces one surface of the window 151a of the mobile terminal is attached to the carrier film 301 This is a step of arranging the touch pattern portion 310 to be transferred onto the window 151a (see FIG. 7A).

The step of transferring the touch pattern part 310 to the window 151a by pressing or heating the carrier film 301 may include pressing or heating the carrier film 301 toward the window 151a, This is a step of transferring the touch pattern part 310, the signal transmission part 312, and the flexible circuit board connection part 314 on the carrier film 301 onto the window 151a (see FIG. 7(b)). The pressurization and heating can occur simultaneously.

Here, the window 151a may be glass or plastic. When the window 151a is made of glass, the temperature required to form the window 151a to bend is about 450 to 550 degrees Celsius. Accordingly, it is preferable that the metal mesh forming the touch pattern part 310 has a melting point higher than the temperature so as not to be liquefied at the temperature for molding. The metal mesh may be aluminum (melting point: approximately 660 degrees Celsius). When the window 151a is made of plastic, the temperature required to mold the window 151a to bend is approximately 100 to 200 degrees Celsius.

In addition, the metal mesh is formed of an inorganic material and, unlike ITO, which has a brittle property, has strong bending or bending ductility, so that it may not be broken even if a large curvature is applied to the window 151a to be transferred.

Removing the carrier film 301 from the window 151a is a step of removing the carrier film 301 after transferring the touch pattern part 310 to the window 151a. By removing the carrier film 301, only the transferred touch pattern portion 310 remains on the window 151a.

The step of deforming the window 151a to which the touch pattern part 310 is transferred by pressing the window 151a so as to have a curved shape is a step of bending the window 151a to suit needs. In the step of bending the window 151a, heat must be applied to the window 151a as described above. Therefore, as described above, it is preferable that the touch pattern part 310 has a melting point at a temperature higher than the heat applied to the window 151a. The window 151a may be variously formed from a large radius of curvature to a small radius of curvature. As the window 151a is bent, the touch pattern portion 310 transferred to the window 151a is also bent.

The step of the manufacturing method of the curved window 151a of the mobile terminal may further include attaching the cover unit 330 and attaching (arranging) the display unit 151.

Attaching the cover part 330 may include the cover part 330 covering at least a part of the touch pattern part 310 so as to prevent the touch pattern part 310 from being peeled off from the window 151a. This is a step of attaching to the window 151a.

In the step of attaching the display unit 151, after the step of deforming the window 151a to have a curved shape, the display unit 151 in a curved shape to cover the metal mesh portion attached to the window 151a. ) Is attached to the window 151a.

7 is a conceptual diagram illustrating a method of manufacturing an example of a curved window 151a according to the present invention.

In describing the present embodiment, a description that is duplicated with the above description will be omitted.

(a) is a step of arranging the touch pattern portion 310 attached to the carrier film 301 to attach to the window 151a. An adhesive material for transferring the touch pattern part 310 to one surface of the window 151a may be included on the touch pattern part 310 or on one surface of the window 151a to which the touch pattern part 310 is transferred. have.

(b) is to transfer the touch pattern part 310 to the window 151a by attaching the carrier film 301 to one surface of the window 151a and then pressing or heating the carrier film 301 This is the step to make.

(c) is a step of removing the carrier film 301 after the touch pattern part 310 is transferred to the window 151a, and pressing the window 151a in a heated state to form a curved window 151a. to be. Unlike shown in the drawings, the curvature of the window 151a to be molded may be increased to the extent that it is bent at an angle of 90 degrees. Through this molding, the window 151a may be molded to cover the front and side surfaces of the mobile terminal.

(d) shows the state after the window 151a is molded. Since the window 151a has a curved surface, the touch pattern part 310 is disposed on the upper or lower surface of the window 151a, so that tensile stress or compressive stress may be generated in the touch pattern part 310. However, since the touch pattern part 310 is a material having ductility, it is prevented from being easily broken or broken by the tensile stress or compressive stress.

(e) is a step of attaching the display unit 151 to the window 151a so as to cover the touch pattern unit 310 transferred to the window 151a. The curved window 151a manufactured in this way may serve as a module to which a display unit and a window are attached in the mobile terminal.

8 is a conceptual diagram illustrating a method of manufacturing another example of the curved window 151a according to the present invention.

In the description of the present embodiment, a description redundantly with the above embodiment will be omitted.

Since (a) to (c) are the same steps as in the above embodiment, the description will be omitted.

(d) is at least a part of the touch pattern part 310 to prevent the touch pattern part 310 from being peeled off from the window 151a after the touch pattern part 310 is transferred to the window 151a. This is a step of covering the cover part 330 covering the. By attaching the cover part 330, it is possible to prevent the touch pattern part 310 from being peeled off from the window 151a during the process of bending the window 151a later.

Here, the cover part 330 may be a film having a thickness thinner than that of the window 151a, unlike that shown in the drawing. By attaching such a film, it is possible to more effectively prevent the touch pattern portion 310 from being peeled off from the window 151a.

And, unlike this, the cover part 330 may be a bonding window 330 having a predetermined thickness.

(e) shows the state after the window 151a and the cover part 330 are formed to be bent.

The case where the cover part 330 is the bonding window 330 will be mainly described.

After the window 151a and the bonding window 330 are bonded, when the window 151a and the bonding window 330 are bent with a curvature, a compressive stress due to compression occurs in the curved inner portion, and the curved outer portion Tensile stress due to tension occurs in the. At this time, between the window 151a and the bonding window 330, a neutral plane 331 in which tensile stress or compressive stress does not occur is positioned.

When the cover part 330 is a bonding window 330 having a predetermined thickness, the touch pattern part 310 is formed of compressive stress or tensile stress due to bending of the window 151a and the cover part 330. It may be disposed on a neutral plane 331 between the window 151a and the cover part 330 in which generation is reduced. When the touch pattern part 310 is placed on the neutral surface 331, tensile or compressive stress applied to the touch pattern part 310 is reduced, so that the touch pattern part 310 is formed of the window 151a. It has the advantage of further reducing the risk of damage that is broken by or does not exhibit its performance.

(f) is a step of attaching the display unit 151 toward the rear surface of the cover unit 330. This is the same as step (e) of FIG. 7.

9 is a conceptual diagram showing another example of a curved window 151a according to the present invention.

In the present embodiment, only one of the X-axis etching line 303 or the Y-axis etching line 304 (refer to FIG. 5) may be formed in the touch pattern part 310. The two metal meshes forming the touch pattern part 310 are insulated from each other by the bridge part 323 having an insulating property, and may be arranged to sense the position of a signal in different directions.

The touch pattern part 310 may include a first metal mesh 321, a second metal mesh 322, and a bridge part 323.

The first metal mesh 321 may extend in one direction on the window 151a to sense a position of an electric signal.

The second metal mesh 322 extends on the window 151a in a direction different from the direction sensed by the first metal mesh 321 to sense the position of the electric signal, and the first metal mesh ( 321) and at least a portion may be formed to overlap.

The bridge part 323 is disposed between the first metal mesh 321 and the second metal mesh 322 and may insulate the first and second metal meshes 322 from each other.

Thereafter, a cover part 330 covering the second metal mesh 322 may be further attached. In addition, a method of forming the window 151a to bend after attaching the cover part 330 is the same as described above.
