The roll-slide mobile terminal 100 of the present invention is assumed to have a bar shape, but may be provided in other forms within the range that does not contradict the characteristics of the present invention.

The roll-slide mobile terminal 100 of the present invention refers to a mobile terminal to which a flexible display is applied to the mobile terminal described above. A flexible display refers to a display that bends so that the wrapping area can be varied.

A flexible display is a lightweight, durable display that does not break easily and is manufactured on a thin, flexible substrate that can be bent, bent, folded, twisted or curled like paper while maintaining the characteristics of existing flat displays.

A flexible display can be combined with a touch sensor to create a flexible touch screen. When a touch is made on the flexible touch screen, the controller can perform control corresponding to the touch input.

The touch sensor detects a touch (or touch input) applied to the touch screen using at least one of several touch methods, such as a resistive method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method.

As an example, a touch sensor may be configured to convert changes in pressure applied to a specific part of the touch screen or capacitance occurring in a specific part into an electrical input signal. The touch sensor may be configured to detect the position, area, pressure at the time of touch, capacitance at the time of the touch, etc., at which the touch object touching the touch screen is touched on the touch sensor.

Meanwhile, the roll-slide mobile terminal 100 according to this modified example may be equipped with deformation detection means capable of detecting deformation of the flexible display. This strain detection means may be included in the sensing unit.

Information related to deformation may include the direction in which the flexible display was deformed, the degree of deformation, the deformed position, the deformed time, and the acceleration at which the deformed flexible display is restored. In addition, various types of information that can be detected due to the bending of the flexible display. It could be information.

In addition, the control unit 180 changes information displayed on the flexible display or controls the functions of the roll-slide mobile terminal 100 based on information related to the deformation of the flexible display detected by the deformation detection means. A control signal can be generated for

Deformation of the state of a flexible display (i.e. expansion or contraction of the front area) is not limited to external forces. For example, the front area of a flexible display can be expanded or contracted by commands from the user or application. In order for the flexible display to be deformed like this without external force, it may include a driving module.

When a flexible display covers not only the front but also the back, the space where the antenna, which is conventionally implemented in the rear case, can be mounted is limited. Therefore, an antenna can be implemented on a flexible display. An antenna with a built-in display (AOD: Antenna on Display) is an antenna that consists of a transparent film made up of a patterned electrode layer and a dielectric layer. The display-embedded antenna can be implemented thinner than the LDS (Laser Direct Structuring) technology implemented using the existing copper nickel plating method, so it has the advantage of not being visible on the outside while having little effect on the thickness.

The display unit 151 described above may be implemented as a flexible display, and the flexible display unit 151 refers to a set of a plurality of panels including a flexible display that directly perform an output function. For example, the flexible display unit 151 may include a flexible display and a touch screen, and the above-described properties of the deformable flexible display are equally applied to the flexible display unit 151. The display unit 151 mentioned below is assumed to be a flexible display unit 151 unless otherwise specified.

Figure 2 is a front perspective view of the display unit 151 of the roll-slide mobile terminal 100 according to an embodiment of the present invention before and after expanded, and Figure 3 is a front perspective view of the roll-slide mobile terminal 100 according to an embodiment of the present invention. This is a rear view of the display unit 151 of 100 before and after it is expanded.

The display unit 151 may be fixed on one side in the front area with respect to the roll-slide mobile terminal 100, wound around one corner of the roll-slide mobile terminal 100, and provided over the back. First of all, the front area 151F of the display unit 151 can be expanded at the corners. When the front area 151F of the display unit 151 is expanded, the rear area 151R of the display unit 151 is reduced. Conversely, when the front area 151F of the display unit 151 is reduced, the rear area 151R of the display unit 151 is expanded.

At this time, the direction in which the front area 151F of the display unit 151 is expanded is defined as the first direction. As the front area 151F becomes wider, the winding area 151C of the display unit 151 moves in the first direction, and as the front area 151F of the display unit 151 becomes narrower, the winding area 151C of the display unit 151 moves in the first direction. The winding area 151C moves in a direction opposite to the first direction.

In order to guide and support the display unit 151 as it expands and contracts, the frame supporting it also expands and contracts. The case 200 forming the exterior of the roll-slide mobile terminal 100 includes a first frame 210 and a second frame 220. The second frame 220 can slide in the first direction with respect to the first frame 210. Of course, since the movement of the first frame 210 and the second frame 220 is relative, the fixed member and the sliding member can be described in reverse.

In this embodiment, among the first frame 210 and the second frame 220, the first frame 210 forms the main exterior area, and the second frame 220 is drawn out from within the first frame 210. It is assumed that it comes out. Accordingly, the main electrical parts may be provided in the first frame 210.

The display unit 151 may be wound around an end of the case in the first direction and provided over the front and back of the case. In reality, one of the front or back sides may not be exposed to the outside, but it serves the purpose of having at least one side visible to the outside.

The display unit 151 has a winding area that varies according to the slide movement of the second frame 210. Among the front area 151F of the display unit 151, the area that is maintained regardless of expansion and contraction is defined as the fixed area 151U, and the area selectively exposed to the front according to expansion and contraction is defined as the variable area 151X. Additionally, the area between the rear area 151R of the display unit 151 and the front area 151F of the display unit 151 is defined as the winding area 151C. Accordingly, the variable area 151X may be included in the front area 151F or the rear area 151R, depending on the case.

The fixed area 151U of the front area 151F of the display unit 151 may be fixed to the first frame 210 or the second frame 220. In this embodiment, it is assumed that the frame is fixed to the second frame 220. That is, when the second frame 220 slides in the first direction based on FIG. 2, the fixed area 151U of the display unit 151 fixed to the second frame 220 also moves. However, as described above, this is not limited and the opposite case can also be established.

When the second frame 220 is slid in the first direction and expanded from the first frame 210, the front area 151F of the display unit 151 is also expanded so that the fixed area 151U and the variable area 151X are expanded to the front. is exposed, and when the second frame 220 is slid in the direction opposite to the first direction and is reduced to the first frame 210, the front area 151F of the display unit 151 is also reduced to cover only the fixed area 151U. It will remain.

The back area 151R of the display unit 151 may be exposed on the back of the second frame 220. The rear area 151R of the display unit 151 is covered by a light-transmissive rear window and can be viewed from the outside. However, of course, if necessary, the rear area 151R can be implemented in a form that is not visible to the outside. The rear cover serves to cover and protect the fluid structure of the display unit 151 moving on the back of the second frame 220 as much as possible.

Meanwhile, the front area 151F of the display unit 151 may be exposed to the front without a separate window. However, the deco frame covers the border area between the front area 151F of the display unit 151 and the first frame 210 to prevent the inflow of external substances and covers the bezel area of the roll-slide mobile terminal 100 to display the user's screen. It can help with visibility.

Electrical parts may be formed in the internal space formed by the exterior structures of the first frame 210 and the second frame 220, and electronic components that drive the roll-slide mobile terminal 100, such as the battery 191, may be It may be mounted on the main board (main-PCB, 181) and provided in the electrical unit. Alternatively, electronic components, such as an internal antenna module, may be installed directly in the electrical equipment unit without going through the main board 181.

Figure 4 is a rear view before and after expansion showing the roll-slide mobile terminal 100 according to an embodiment of the present invention, and Figure 5 is a before and after expansion showing the roll-slide driving module according to an embodiment of the present invention. is a rear view, and Figure 6 is a perspective view and an exploded perspective view of a roll-slide drive module according to an embodiment of the present invention.

As shown in FIG. 4, the slide movement of the second frame 220 with respect to the first frame 210 may be driven by the driving module 240 inside the device.

Referring to FIG. 5 together, the drive module 240 includes a mounting plate 241 fixed to the back of the first frame 210, and a long guide slit that penetrates along the first direction from the outside of the mounting plate 241. (242), a driving slider 244 that is inserted into the guide slit 242 and moves along the first direction, and the upper protruding catch portion 244a is inserted into the lead hole 221 of the second frame 220, and One floating end (245e) is coupled to the driving slider 244, and the other fixed end (245c) is fixed to the inside of the mounting plate 241 by a fixing pin 243, and the floating end is moved through the central compression portion (245a). It may be configured to include a torsion spring 245 that applies rotational force to (245e) and the fixed end (245c).

The driving module 240 may be placed alone on one side of the roll-slide mobile terminal 100 to secure the internal space of the mobile terminal 100, but the roll-slide mobile terminal 100 of this driving module 240 ) When placed on one side, the force of the driving module 240 applied to the second frame 220 is concentrated on only one side of the second frame 220, creating an imbalance, so as shown in the drawing, the second frame 220 Drive modules 240 may be mounted on both left and right sides of the first frame 210 in a direction perpendicular to the first moving direction, so that two drive modules 240 may be provided as a set.

The mounting plate 241 is formed in the shape of a plate and is fixedly installed on the back of the first frame 210. A guide slit 242 is formed long along the first direction on the outside of each of the mounting plates 241 on both sides, and is located on the main body of the mounting plate 241 at a position corresponding to the starting position of the guide slit 242 in the first direction. The fixed shaft mounting portion 241a, which protrudes inwardly where the mounting plates 241 on both sides face each other, extends. The fixed end 245c of the torsion spring 245 is fixed to the fixed shaft mounting portion 241a of the mounting plate 241, and the floating end 245e of the torsion spring 245 is inserted into the guide slit 242 and moves. It is coupled to the slider 244 and moves.

The guide slit 242 has a penetrating shape and is formed long along the first direction on the outside of the mounting plate 241. A driving slider 244 is inserted into the guide slit 242 and moves along the guide slit 242 in the first direction or in a direction opposite to the first direction. As shown in FIG. 4, the catch portion 244a protruding upward from the driving slider 244 is inserted into the lead hole 221 formed in a penetrating shape in the second frame 220, so that the driving slider 244 Movement in the first direction or in a direction opposite to the first direction is linked to movement of the second frame 220 in the first direction or in a direction opposite to the first direction. That is, when the driving slider 244 moves in the first direction in the guide slit 242, the second frame 220 linked thereto also moves in the first direction, and as a result, the roll-slide mobile terminal 100 is expanded. Conversely, when the driving slider 244 moves in the direction opposite to the first direction in the guide slit 242, the second frame 220 linked thereto also moves in the direction opposite to the first direction, resulting in the roll-slide movement terminal 100 ) is reduced.

The movement of the driving slider 244 is achieved by changing the compression and restoration states of the torsion spring 245, and the changes in the compression and restoration states of the torsion spring 245 are caused by the user's second frame ( 220), the roll-slide driving module according to an embodiment of the present invention operates semi-automatically depending in part on the force applied by the user.

Referring to FIG. 6 together, the torsion spring 245 connects the second frame 220 and the first frame 210 to allow the second frame 220 to slide in the first direction or in the direction opposite to the first direction. To provide torsion, a compression portion (245a) wound a predetermined number of times, a fixed arm (245b) and a floating arm (245d) extending on both sides of the compression portion (245a) and opening in straight lines in different directions. It is composed of a fixed end 245c and a floating end 245e, which are each wound a predetermined number of times around the ends of the fixed arm 245b and the floating arm 245d.

Here, the fixed end 245c of the torsion spring 245 is rotatably fixed to the fixed shaft mounting portion 241a of the mounting plate 241 by a fixed pin 243. Additionally, the moving end 245e of the torsion spring 245 is rotatably wound around the driving slider 244 and moves along the guide slit 242. The torsion spring 245 is in a restored state in which no rotational force is generated when the fixed arm 245b and the floating arm 245d form a wide angle, as shown in (b) of FIG. 6. Conversely, the torsion spring 245 is in a compressed state when the fixed arm 245b and the floating arm 245d form a narrow angle, as shown in (a) of FIG. 6, and at this time, the fixed arm 245b and the floating arm 245d are compressed. ), a rotational force is generated to return to the restored state.

Accordingly, the fixed end 245c of the torsion spring 245 is fixed to the mounting plate 241 on the first frame 210 and at the same time the floating arm 245d of the torsion spring 245 is moved to the second frame 244 through the drive slider 244. In the state shown in (a) of FIG. 6, which is provided to move in conjunction with the frame 220, when the user slightly pushes up the second frame 220 in the first direction, the torsion spring 245 has a rotational force to return to the restored state. When this happens, the driving slider 244 moves quickly in the first direction, as shown in (b) of FIG. 6, and eventually the second frame 220 moves in the first direction.

Conversely, in the state shown in (b) of FIG. 6, when the user slightly pulls down the second frame 220 in the direction opposite to the first direction, the torsion spring 245 is compressed. At this time, as the torsion spring 245 passes the maximum compression state and enters the undercompression state again, a rotational force is generated in the torsion spring in the maximum compression state to return to the undercompression state, and the drive slider 244 is first compressed as shown in (a) of FIG. 6. It moves all the way in the opposite direction, and eventually the second frame 220 moves in the direction opposite to the first direction.

Here, the torsion spring 245 goes through a restoration state, a maximum compression state, and a low compression state by a weak force assisted by the user, and semi-automatic operation of the roll-slide driving module is achieved.

Figure 9 is a diagram for explaining the operating principle of the roll-slide driving module according to an embodiment of the present invention.

As shown in (a) of FIG. 9, the moving end 245e of the torsion spring 245 is rotatably wound around the driving slider 244 and moves along the guide slit 242. Additionally, the fixed end 245c of the torsion spring 245 is fixed to the mounting plate 241.

At this time, the most distal point in the first direction of the guide slit 242 formed long along the first direction is the restoration point A, and when the moving end 245e of the torsion spring 245 is moved to this position A, the torsion The spring 245 is in a restored state in which no rotational force is generated.

In addition, the point at the guide slit 242 that is horizontal to the fixed end 245c of the torsion spring 245 is the maximum compression point B, and when the floating end 245e of the torsion spring 245 is moved to this position (B), The torsion spring 245 is in the maximum compressed state, and at this time, the rotational force to return to the restored state is generated the most strongly.

In addition, the most distal point in the guide slit 242 in the direction opposite to the first direction beyond the point B that is horizontal to the fixed end 245c of the torsion spring 245 is an undercompression point C, and the torsion spring 245 When the floating end (245e) of the torsion spring 245 is moved to this position (C), the floating end (245e) of the torsion spring 245 cannot return to the maximum compression state of B and maintains that position. Therefore, with the moving end 245e of the torsion spring 245 located at the undercompression point C, the second frame 220 moves in the opposite direction to the first direction, and as a result, the roll-slide moving terminal 100 is reduced. It becomes closed. At this time, if no special external force is applied, the floating end 245e of the torsion spring 245 does not travel back from the undercompression point of C to the maximum compression point of B and remains closed.

Here, when the user pushes the second frame 220 up in the first direction with a weak force, the moving end 245e of the torsion spring 245 passes the maximum compression state of B, and the torsion spring 245 is restored. Due to the rotational force, the flow end 245e is suddenly moved to the restoration point of A, which is the most end in the first direction, and as a result, the roll-slide moving terminal 100 is expanded and opened. At this time, unless a special external force is applied, the floating end 245e of the torsion spring 245 does not travel back from the restoration point of A to the maximum compression point of B and maintains its open state.

Ultimately, when the user pushes the second frame 220 in the first direction with a weak force, the moving end 245e of the torsion spring 245 moves to the recovery point of A by the torsion spring 245 and opens semi-automatically. do. In addition, when the user pulls the second frame 220 in the direction opposite to the first direction with a weak force, the moving end 245e of the torsion spring 245 moves to the recovery point of C by the torsion spring 245 and closes semi-automatically. It becomes a state.

The operating principle of this torsion spring 245 is shown in the graph of FIG. 10.

When the moving end 245e of the torsion spring 245 is at the recovery point of A, the torsion spring 245 is in a state where no compression occurs, and at the maximum compression point of B, the torsion spring 245 is compressed to the maximum, At the undercompression point of C, the torsion spring 245 is undercompressed.

Therefore, the guide slit 242 must be formed so that the open end in the direction opposite to the first direction is longer in the direction opposite to the first direction compared to the position where the fixed end 245c of the torsion spring 245 is fixed. More precisely, the end of the guide slit 242 in the first direction should be designed to match the mechanical full recovery angle of the torsion spring 245, and the end in the direction opposite to the first direction should be designed to exceed the maximum compression angle of the torsion spring 245. Again, it must be designed according to the angle of undercompression.

Referring again to FIG. 7, the fixed end 245c formed by winding a predetermined number of times at the end of the fixed arm 245b of the torsion spring 245 is connected to the fixed shaft mounting portion of the mounting plate 241 by the fixed pin 243. 241a). The fixing pin 243 is coupled to the fixed shaft mounting portion 241a so as not to rotate to prevent the fixed end 245c of the torsion spring 245 from moving upward, and this fixed end 245c and the fixed shaft mounting portion 241a A rotation washer (243a) is interposed between them to facilitate the rotational movement of the fixed end (245c).

In addition, the floating end 245e formed by winding the end of the floating arm 245d of the torsion spring 245 a predetermined number of times flows while inserted into the guide slit 242 by the driving slider 244. The driving slider 244 is centered around a seating portion 244b that protrudes along the side and seats the moving end 245e at the top, and an insertion portion 244c extending downward and protruding is inserted into the guide slit 242. , the catch portion 244a extending upward and protruding is formed to be inserted into the lead hole 221 of the second frame 220. A rotation washer 244d is interposed between the flow end 245e and the catch portion 244a to smoothly rotate the flow end 245e.

Figure 8 is a perspective view and a cross-sectional view of a guide rail and guide slider of a drive module according to an embodiment of the present invention.

Meanwhile, on the outside of the guide slit 242 of the drive module 240, there is a guide rail 246 arranged in a straight line similar to the straight shape of the guide slit 242, and the second frame 220 slides along the guide rail 246. ) The driving module 240 may be configured to further include a guide slider 247 coupled to the.

Therefore, since the guide rail 246 and the guide slider 247 guide the movement of the second frame 220 next to the guide slit 242, the movement of the second frame 220 in the first direction and the first When moving in the opposite direction, smooth movement of the second frame 220 is possible.

The guide rail 246 and the guide slider 247 coupled to the second frame 210 that slides in the first direction or in the direction opposite to the first direction by the drive slider 244 are located next to the guide slit 242. It is installed on the first frame 210. Therefore, when the driving slider 244 in the guide slit 242 moves the second frame 220 by the torsion spring 245, the guide rail 246 and the guide slider 247 next to it move the second frame 220. ) guides the movement.

The guide rail 246 is fixed on the first frame 210 to correspond to the arrangement of the guide slit 242, and a guide bar 246a protrudes long along the longitudinal direction of the guide rail 246 on the upper side. is formed In addition, the guide slider 247 has a coupling groove 247a formed on both upper sides for coupling with the second frame 220, and has a recessed lower portion into which the guide bar 246a of the guide rail 246 can be inserted. A guide slot 247b is formed.

A screw penetrating the second frame 220 is inserted into the coupling grooves 247a formed on both upper sides of the guide slider 247, so that the forward and backward movement of the second frame 220 remains the same as the forward and backward movement of the guide slider 247. It is linked with

Since the guide bar 246a of the guide rail 246 is inserted into the guide slot 247b formed in the lower part of the guide slider 247, the guide slider 247 to which the second frame 220 is coupled to the upper side ) can remain coupled to the guide rail 246.

As the second frame 220 moves, the guide slider 247 moves forward or backward along the guide rail 246 in a straight line and supports the second frame 220 from the bottom.
