1 to 5, the flexible display device 100 according to an exemplary embodiment of the present invention is fixed to a portion having a predetermined range from one end of the flexible panel 10, and thus the flexible panel 10 may not be freely bent and the other portion thereof is not fixed. ); A fixed body 20 to which a predetermined area portion of the flexible panel 10 is fixed; The remaining portion of the flexible panel 10 which can be freely bent away from the fixing body 20 is diverted so as to prevent bending, so as to be stored and protected therein and to be supported by the fixing body 20 only in a limited range. It may include a single protective cover assembly 30 to perturb and to perform a spread area control function for the flexible panel 10 accommodated therein.

6 to 9, the flexible display device 100 according to another exemplary embodiment of the present invention is fixed to an intermediate portion separated from both ends by a certain degree so that the bending is not free and the remaining portions of both ends are not fixed so that the flexible display device 100 is freely bent. Flexible panel 10; A fixed body 20 to which a predetermined area portion of the flexible panel 10 is fixed; The remaining portion of the flexible panel 10 which can be freely bent away from the fixing body 20 is diverted to prevent bending, so that each is protected inside and supported by the fixing body 20 only in a limited range. It may include a pair of protective cover assembly (30) for perturbing and performing the spread area control function for the flexible panel 10 accommodated therein.

As shown in FIG. 5 and FIG. 9, the flexible panel 10 is not fixed to the fixed body 20 but fixed to only a portion thereof, so that the flexible panel 10 has a high flexibility to the fixed body 20 which is relatively inflexible. This is because application of the minimum curvature of the flexible panel 10 is easier than when the entire flexible panel 10 is fixed.

However, only a portion of the flexible panel 10 is fixed to the fixing body 20 and the remaining portion is freely bent so that the entire flexible panel 10 is fixed to the fixing body 20. As compared with the case, the problem of the storage of the flexible panel 10 and the good flatness of the plate-shaped shape is difficult to use when carrying.

If such a problem is solved, the flexibility of the flexible panel 10 can be taken advantage of, and the flexibility of the flexible panel 10 can be secured and the flexible display device 100 can be realized .

As shown in the embodiment shown in Figure 1 to Figure 11 for the purpose of the present invention to protect the rest of the flexible panel 10 that is not fixed to the fixed body 20 therein and to perturb and move as necessary The protective cover assembly 30 performs a function of unfolding and maintaining the accommodated flexible panel 10 in a flat state.

The protective cover assembly 30 includes a protective cover 40 for receiving and protecting a portion of the flexible panel 10 therein while being perturbed and supported by the fixed body 20; The protective cover 40 is rotatably assembled inside the protective cover 40 to maintain a stable curvature for preventing a change in direction and bending of the portion of the flexible panel 10 that is drawn into the protective cover 40, A roller (60) for supporting a contact surface with the roller (10); And a drive shaft is connected to the roller 60 is configured to include a motor 70 for generating a driving force to the roller.

One end of the protective cover 40 has an inlet portion which is formed so as to extrapolate the fixed body 20 and the flexible panel 10 can enter and exit therein. In addition, the protective cover 40 is formed through a predetermined portion of the protective cover 40 for easy assembly and maintenance of the roller 60 and the motor 70 assembled inside the protective cover 40. It has an assembly through-hole 41 and the assembly through-hole 41 is covered and maintained as an assembly through-hole cover 50 to prevent the entry of foreign matter.

In addition, before and after changing the direction of the flexible panel 10 inside the protective cover 40, the flexible panel 10 maintains a constant path in the protective cover 40 and unnecessary with the fixing body 20. Panel path guides 42 are formed at portions where both ends of the flexible panel 10 are positioned so that they can move without interference.

Apart from the panel path guide 42, the protective cover 40 may be disposed in contact with a portion of the flexible panel 10 introduced into the protective cover 40 and an inner surface of the protective cover 40. Friction reducing material 43 is applied to prevent the occurrence of movement resistance and scratches of the flexible panel 10 by the friction reducing material 43 may be applied over the entire inner area of the protective cover 40, For ease of application it may be selectively applied only to some areas, such as the point of curvature change of the flexible panel.

The protective cover assembly 30 wraps around the outer surface of the fixed body 20 and is perturbed to the fixed body 20 side as much as possible to increase the portability of the flexible panel fixed to the fixed body 20 ( The image display surface of 10) is open to the entrance portion over a predetermined area of the protective cover 40 so that the protective cover 40 is visible to the user without being covered by the protective cover 40 The display surface opening 44 is formed.

In addition, when the user perturbates the protective cover assembly 30 in the outward direction of the fixing body 20 by using a hand, the finger holding the outer surface of the protective cover 40 slides from the protective cover 40. The protective cover 40 has a non-slip shape 45 is formed on a portion of the outer surface of the protective cover 40 so as not to be supported.

The non-slip shape can be applied to the protrusion protruding to the outer surface of the protective cover 40, as shown in the embodiment shown in Figures 1 to 11, and other embodiments such as the application of unevenness is possible.

The perturbation movement of the protective cover assembly 30 is applicable in the case of the unfolding operation, in which the user pulls out the protective cover 40 by hand or unfolds the flexible display by magnetic force by inertia. On the contrary, in the case of the folding operation, when the user starts to move the protective cover assembly 30 to the inside by applying an external force to the protective cover 40, the position detecting device 90 which will be described later detects it. Providing information indicating the start of folding to the control unit of the display device 100, the control unit operates the motor 70 to suck the flexible panel 10 to the inside of the protective cover 40, the reaction by the protection The cover assembly 30 is applied in a manner that is moved toward the fixed body 20.

In the operation step and the end step of the perturbation movement operation of the protective cover assembly 30, an impact that may cause damage to the flexible panel 10 may occur, it is required to apply a countermeasure for preventing it. In the case where such an impact can occur, the unfolding to the outside is usually done in a form in which the user can adjust the salary, whereas when folded, the end is formed by a driving force by the motor and thus cannot be adjusted by the user. It is important to be prepared for the rapid impact of the stage.

Therefore, when the perturbation movement toward the fixed body 20 side of the protective cover assembly 30 is completed, as shown in FIGS. 7, 8 and 11, the sudden stop of the protective cover assembly 30 is achieved. Shock absorbing means 91 is applied to one side of the fixed body 20 or the protective cover assembly 30 so as to minimize the impact of the flexible panel 10, the shock absorbing means 91 is capable of absorbing shock Spring, rubber and cork applications are possible.

When the perturbation movement of the protective cover assembly 30, the fixing portion of the flexible panel 10 fixed to the fixing body 20 is protruded may cause interference with the protective cover assembly 30, if the flexible continuously occurs It may damage the panel 10. Therefore, as shown in FIG. 3, when a perturbation movement of the protective cover assembly 30 occurs, a predetermined region of the flexible panel 10 fixed to one surface of the fixing body 20 may be affected by the protective cover assembly 30. A predetermined area of the flexible panel 10 is buried in one surface of the fixing body 20 so as to protrude above the copper surface so as not to interfere with the protective cover assembly 30.

5 and 9, the connecting connection portion 11 of the flexible panel 10, which allows the flexible panel 10 to be electrically connected to the fixed body 20, (10) so as to be protected from being exposed to a user regardless of the perturbation movement of the flexible panel (10), the protective cover assembly (30) being located at a certain distance from the center line of the fixed body A connection connecting portion 11 is disposed.

When the user performs a continuous touch with a finger on the surface of the flexible panel 10 that has been unfolded as well as performing the spreading or winding of the flexible panel 10, the flexible panel 10 moves little by little to the flexible panel 10. This may occur if you need to readjust the tension. In order to uniformly perform the spreading or winding performance including the tension control of the flexible panel without the distortion of the flexible panel 10, the flexible panel 10 is the protective cover assembly 30 as shown in FIGS. 5 and 9. ) Has a plurality of engaging through-holes 12 formed in parallel at regular intervals facing each other at a predetermined distance from the end of both sides of the side of the flexible panel 10 introduced into the central portion.

As shown in FIGS. 1 and 2, the flexible display device 100 may perform information input / output, music listening and charging functions using a connection jack, in addition to a basic function of simply displaying an image using the flexible panel 10. And by taking advantage of the built-in camera 22 can also perform image shooting. To this end, regardless of the perturbation movement of the protective cover assembly 30, the fixed body facing the protective cover 40 so that a user applies a connection jack to the fixed body 10 or freely manipulates an operation button ( On the opposite side of the exposure side 20) the connection jack application part or the operation button 21 is located. In addition, when the camera 22 is built in the fixed body 20, the protective cover 40 includes the protective cover 40 for photographing using the camera 22 regardless of the perturbation movement of the protective cover assembly 30. ), One end of the protective cover 40 is removed so that the camera interference prevention part 46 is formed.

6 to 8, when the pair of protective cover assemblies 30 are applied to both sides of the fixed body 20, the pair of protective cover assemblies 30 are configured to maximize portability. In the state that the unfolding degree of the panel 10 is minimal, the front entrance portion of the protective cover 40 on one side is inserted into the inner space of the other protective cover 40 located on the opposite side and is accommodated to improve portability. Has
