The mobile terminal of the present invention can be switched in shape as shown in FIG. 2 and FIG. The first state is a wristband type terminal or a watch type terminal that can be wound around a user's hand (see Fig. 2). In the second state, a flat display unit 151 is located on the front side Type terminal (refer to FIG. 3).

As shown in FIG. 2, in the first state, since the mobile terminal is wound around the user, the mobile terminal forms a closed curved surface formed along the circumference of the user's cuff. On the other hand, in the second state, the folded portions 103 located on both sides of the closed curved surface of the first state are folded and folded to be converted into double folded bar shaped terminals. The folded portion 103 is folded at 0 DEG to maintain a double folded bar shape in the second state and at an angle less than 180 DEG so as to be wound on the user's wrist in the first state.

The terminal of the present invention includes a main body 101 on which a display unit 151 is mounted on the front side and a strap 102 connected to both sides of the main body 101 in the first direction to form a main body 101 and a closed curved surface, . The strap 102 includes a bent portion 103 whose angle can be changed. When the strap 102 and the main body 101 are overlapped with each other at an angle of the bent portion 103, the terminal is transformed into a bar terminal as shown in FIG.

At this time, the main body 101 and the strap 102 may be made of a flexible material, or the angle between the plurality of plate-shaped modules and the plate-shaped module may vary, and the curvature of the entire mobile terminal may be changed.

4 is a perspective view of the mobile terminal shown in FIG. 2 according to an embodiment of the present invention. Magnets 107a and 107b may be provided on at least one side so that the overlapped strap 102 and the main body 101 are not separated to maintain the second state.

(107b). Or vice versa.

When the strap 102 and the main body 101 are brought close to each other by a predetermined distance or more in the first state, the magnets 107a and 107b are switched to the second state by the magnetic attraction between the strap 102 and the main body 101, When a predetermined force is applied in the second state, the strap 102 and the main body 101 can be separated from each other and can be switched from the second state to the first state.

As shown in FIG. 2, the main body 101 of the mobile terminal according to the embodiment of the present invention shown in FIG. 2 is formed of a flexible material and can be transformed from a flat state to a curved state. As shown in FIG. 3, the terminal can be transformed into a flat shape in the second state and converted into a bar-shaped terminal.

All of the main body 101 may be made of a flexible material, and a part of the main body 101 may be converted into a curved surface while maintaining a linear shape and being only partially bent as shown in Fig.

The display unit 151 mounted on the main body 101 must be deformed according to the shape of the main body 101. The display unit 151 may be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display unit 151. The deformable display unit 151 may be referred to as a 'flexible display unit 151'. Here, the flexible display unit 151 may include both a general flexible display unit 151 and electronic paper (e-paper) and combinations thereof. In general, the mobile terminal 100 may include features of the mobile terminal 100 of Figure 1 or similar features.

The general flexible display unit 151 is formed on a thin and flexible substrate which can be bent, bent, folded, twisted or curled like a paper while maintaining the characteristics of the conventional flat panel display unit 151, (151).

In addition, the electronic paper is a technique of the display unit 151 to which general ink characteristics are applied, and the point of using reflected light is different from the conventional flat panel display unit 151. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

The area of the display portion 151 of the flexible display portion 151 becomes flat in a state in which the flexible display portion 151 is not deformed (for example, in a state of having infinite radius of curvature). In the single-sided state, the area of the display unit 151 may be curved in a state deformed by an external force (for example, a state having a finite radius of curvature). As shown in the figure, the information displayed in the curved surface state of the flexible display unit 151 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 151 is in a flat state (or in a less bent state) when an external force is applied to the flexible display unit 151 in a bent state (for example, Or may be deformed into a more bent state.

Meanwhile, the flexible display unit 151 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, not only in the flat state but also in the curved state.

Meanwhile, the mobile terminal 100 according to the present modification may be provided with a deformation sensing means for sensing deformation of the flexible display unit 151. [ The 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 151 or the case 101 to sense information related to the deformation of the flexible display unit 151. Here, the information related to the deformation may be the direction in which the flexible display unit 151 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformable flexible display unit 151 is restored, In addition, the information can be various information that can be detected due to warping of the flexible display unit 151.

The control unit 180 may change the information displayed on the flexible display unit 151 based on the information related to the deformation of the flexible display unit 151 sensed by the deformation sensing unit, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 100 according to the present modification may include a case 101 that accommodates the flexible display unit 151. The case 101 may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151. [

In addition, the battery 191 included in the mobile terminal 100 may be configured to be deformable together with the flexible display unit 151 by an external force in consideration of the characteristics of the flexible display unit 151. [ In order to implement the battery 191, a stack and folding method in which the cells of the battery 191 are piled up can be applied.

When the mobile terminal 100 is in the first state, the strap 102 is also deformed into a curved surface, and in the second state, it is flattened. The strap 102 may be made of a flexible material such as silicon.

Only the display unit 151 is located in the main body 101 and some members such as the main board 185 and the battery 191 can be positioned on the strap 102. If the electronic components are all disposed only in the main body 101, the thickness of the main body 101 becomes too thick. When the thickness of the main body 101 is thick, it is possible to provide a mobile terminal of a bracelet type when it becomes a watch-type mobile terminal and distributes the electronic components evenly to the main body 101 and the strap 102.

The main board 101 and the battery 191 may be located on the strap 102. The main board 185 may be made of a hard material and may be partly deformed into a curved surface, A flexible substrate 186 may be used as shown in FIG. 4 to connect the display unit 151 of the main substrate 185 and the battery 191 with each other.

The flexible substrate 186 is deformable in accordance with the deformation of the strap 102 and is located inside the strap 102 and extends from the main substrate 185 or the battery 191 to the main body 101, The display unit 151 can be controlled by connecting the main substrate 151 and the main substrate 185. [

The main body 101 may be made of a flexible material such as silicon as a whole, but has a problem of poor rigidity. In order to reinforce the rigidity, as shown in FIG. 5, the outer side is surrounded by a flexible housing 1012 of flexible material, and a plurality of unit blocks 1011 made of a rigid material are arranged in parallel in the first direction. As shown in FIG. 4, the flat portion may be composed of one unit block 1011.

The protrusion 1013 protruding from the inside of the flexible deformable housing 1012 toward the side of the unit block 1011 is inserted into the slot 1014 extending in the first direction on the side surface of the unit block 1011. [ The protrusion moves along the slot 1014 in accordance with the bending of the deformable housing 1012 so that the interval and the angle between the unit blocks 1011 are changed and the main body 101 forms a curved shape as shown in Fig. Can be.

The bending portion 103 may be folded to 0 占 but the hinge connecting the main body 101 and the strap 102 may be changed in 180 占 within a predetermined range.

Since the main body 101 of the present embodiment has the display unit 151 and the main body 101 where the display unit 151 is located is smaller than that of the previous embodiment, The first state and the second state can be changed while the angle of the hinge between the main body 102 and the main body 101 changes.

When the main body 101 is deformable so as to form a curved surface in a first direction which is the circumferential direction of the wrist in a planar state, the length of the main body 101 body can be made longer as compared with the case where the main body 101 is not bent. The display unit 151 can be formed larger. In this case, the length of the strap 102 becomes relatively small, and in particular, the portion of the straps 1021a and 1022a adjacent to the main body 101 at the bent portion 103 is shortened.

The microphone 121 and the sound output unit 152 may be positioned on the straps 1021a and 1022a adjacent to the main body 101 as shown in FIG. 7 so that the user can use the sound output unit 152 ) To the ear and input the user voice through the microphone 121. [

At this time, as shown in FIG. 13, the folded portion 103 is folded, and the straps 102 on both sides are overlapped with the center of the folded portion 103, and the shape is changed to a bar shaped terminal.

16 is a perspective view showing the bent portion 103 of the mobile terminal of Fig. The bending section 103 includes a first rotation shaft 1031a fastened to the strap 102 adjacent to the main body 101 and a second rotation shaft 1031b fastened to the strap 102 overlapping the main body 101 in the second state. And the strap 102 can be overlapped as shown in FIG. 15 by rotating around the respective rotation shafts 1031a and 1031b.

The rotating shafts 1031a and 1031b further include a stator 1033 protruding from the rotating shafts 1031a and 1031b to restrict the rotation angle and prevent the shape from being disorderly deformed to other than the first and second states can do.

The bent portion 103 further includes a hinge cap 1035 which covers the ends of the pair of rotation shafts 1031a and 1031b and a groove 1035 'for receiving the end portion of the rotation shaft is formed in the hinge cap 1035 do. The inner side of the hinge cap 1035 further includes a space in which the stopper 1033 protruded from the rotary shafts 1031a and 1031b can rotate within a predetermined range, and the stopper 1033 moves only in the extra space, The rotation is stopped when it comes into contact with the wall surface of the groove 1035 'of the cap 1035, so that the rotation angle can be limited.

As described above, according to at least one embodiment of the present invention, it is possible to transform into a convenient form according to the situation, so that convenience of carrying and ease of use can all be satisfied at the same time.

In addition, when the watch is converted to a watch type, the entire thickness of the mobile terminal can be uniform, and a mobile terminal having excellent design quality can be provided. Also, since the display unit 151 can be bent, it is possible to provide a large display unit 151 even in a watch-type.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
