[0041] According to the tenth embodiment of the present invention, in the ninth embodiment, the flexible display is characterized in that a region made of a rigid material and a region made of a flexible material are integrated.

[0042] (Modes for Carrying Out the Invention) Hereinafter, preferred embodiments of the flexible display device of a portable terminal according to the present invention will be described in detail with reference to the accompanying drawings.

[0043] FIG. 3 is a perspective view showing the flexible display device of a portable terminal according to the present invention, and FIG. 4 is a side cross-sectional view of the flexible display device of a portable terminal according to the present invention.

[0044] According to FIGS. 3 and 4, the flexible display device of the mobile terminal according to the present invention includes a display unit 100 and a main body 200. The display unit 100 is a flexible display, one side end of which is drawn in and out from the inside of the main body 200, and the other side is exposed on the upper surface of the main body 200. The main body 200 includes a housing 210, at least one of a support unit 130 and a support unit 140 that movably supports and houses one side portion of the flexible display 110 housed inside the housing 210, an upper slider 121 that slidably moves and supports a part of the exposed flexible display 110 on the upper surface 212 of the housing 210, and a lower slider 122 that movably supports the other side of the flexible display 110 housed in the main body 200 on the inner upper surface 213 of the housing 210.

[0045] The flexible display 110 has a portion exposed to the outside on the upper surface of the housing 210 and the other side extended inside the housing 210, and is extended to the upper surface 212 of the housing 210 in a bent form inside the housing 210 due to the characteristics of its own material. Therefore, when the user presses one side of the flexible display 110 exposed on the upper surface 212 of the housing 210, the flexible display 110 is moved in one direction, so the other side housed inside the housing 210 is pulled out and moved to the upper surface 212 of the housing 210.

[0046] Here, the flexible display can be applied to the present invention by manufacturing a display made of a rigid material such as OLED or LCD and a flexible display made of a flexible material as one display. That is, for example, in one display, a composite material display extending from a region made of the rigid material display to a flexible material display region can be applied to the present invention. To explain this, the display region of the rigid material is positioned on the upper surface 212 of the housing 210, and the display region of the flexible material extending from the rigid material display is accommodated inside the housing and bent when moving, so that the region of the display can be expanded.

[0047] Therefore, the user can operate an image output command key (not shown) with the part exposed on the upper surface 212 of the housing 210 and the display accommodated inside the housing 210 all exposed on the upper surface 212 of the housing 210 to view the image through a larger screen.

[0048] The housing 210 is made of plastic or other materials forming the outside of the main body 200 and forms a space inside. Here, the housing 210 is movably fastened to the upper slider 121 at the upper surface 212 and includes a fastening structure in which the lower slider 122 is movably fastened at the inner upper surface 213. This is shown in FIG. 5 below, and the upper slider, the lower slider, and the housing will be described together with FIGS. 3 and 4.

[0049] FIG. 5 is a cross-sectional view simply showing an example of the fastening structure of the flexible display in the flexible display device of the portable terminal according to the present invention.

[0050] According to FIG. 5, the housing 210 includes concavo-convex grooves in which the upper slider 121 is movably fastened at the upper surface 212 and concavo-convex grooves in which the lower slider 122 is movably fastened at the inner upper surface 213. Here, the concavo-convex grooves are characterized by having a trapezoidal shape.

[0051] The upper slider 121 is fixed to the rear surface of one side end portion by the flexible display 110, and is slidably fastened to the concavo-convex groove on the upper surface 212 of the housing 210. That is, the upper slider 121 has a concavo-convex groove formed on its lower surface so as to be movably engaged with the concavo-convex structure of the upper surface 212 of the housing 210. Therefore, when a user applies a force to one side exposed on the upper surface 212 of the housing 210, the upper slider slides along the upper surface 212 of the housing 210 and at the same time supports the flexible display 110. Here, preferably, when a predetermined position is reached on the upper surface of the upper slider and the housing, it is preferable to add a locking configuration for preventing the movement of the upper slider.

[0052] That is, in the concavo-convex movement structure between the upper slider and the upper surface of the housing, it is preferable to form a locking groove (not shown) at the end portion of the upper surface of the housing, and add a protrusion (not shown) to the upper slider that is locked to the locking groove on the upper surface of the housing. Since the fixing structure of the upper slider 121 as described above can also apply generally known techniques, a detailed description thereof will be omitted.

[0053] The lower slider 122 includes a concavo-convex groove that meshes with the concavo-convex groove on the inner upper surface 213 of the housing 210, and slides along the inner upper surface 213 of the housing 210 to support the insertion and extraction of the flexible display 110. Therefore, the lower slider 122 slides simultaneously with the movement of the flexible display 110 to support the flexible display 110. At this time, the flexible display 110 is pulled out to the outside through the extraction hole 211 of the housing 210.

[0054] Here, either the upper slider 121 or the lower slider 122 can be installed alone, or they can be installed simultaneously to guide the movement of the flexible display 110 and support the flexible display 110 to maintain an extended form after the extraction is completed.

[0055] Further, the present invention includes the support portions 130 and 140 that elastically support the flexible display 110 to enable the insertion and extraction of the flexible display 110 as described above, which is shown in FIG. 6.

[0056] According to FIG. 6, the support portion includes a connecting means 130 connected to the other end of the flexible display inside the housing 210, and a rotatable rotating shaft (not shown) to which the opposite end of the connecting means 130 is connected, and a rotating means 140 that can rotate by an elastic force.

[0057] Here, the connecting means 130 is a string or a folding rod, one end of which is fixed to the other end of the flexible display 110 movably accommodated inside the housing 210, and the opposite end is fixed to the outer surface of the rotating means 140, and a force is applied to the flexible display 110 according to the rotation direction of the rotating means 140.

[0058] The rotating means 140 pulls the flexible display 110 with a predetermined force according to the rotation direction of the rotating shaft (not shown) having the elastic force. Therefore, when the flexible display 110 is pulled out, for example, the rotating means 140 is rotated in the positive direction to rotate and release the connecting means 130, and when the flexible display 110 returns to its position and a force in the opposite direction is applied, the connecting means 130 is pulled by the elastic force of the rotating means 140.

[0059] Here, the rotating means 140 is provided with a spring (not shown) inside, and the spring contracts or expands according to the rotation direction, so that an elastic force is applied to enable the rotating shaft to rotate in the forward and reverse directions.

[0060] Here, as another embodiment of the present invention, instead of providing the connecting means 130, it is also possible to roll the other end of the flexible display 110 itself on the outer surface of the rotating means 140. That is, as described above, the flexible display 110 includes a configuration that returns by the elastic force of the rotating means 140 by the connecting means 130. However, as another embodiment, a configuration in which the other end of the flexible display 110 rolls on the outer surface of the rotating means 140 also belongs to the scope of the technical idea of the present invention.

[0061] Furthermore, in the present invention, since the connecting means 130 is pulled when the lower slider 122 moves as described above, the rotating means 140 unwinds the connecting means 130 while rotating in one direction. At this time, when the movement of the flexible display 110 is completed, in order to return the flexible display 110 to its original position by the elastic force of the rotating means 140, it is preferable that a locking configuration for preventing the movement of the flexible display 110 or the lower slider 122 inside the housing 210 is further configured.

[0062] That is, for example, it is preferable to respectively form protrusions (not shown) on both side surfaces of the flexible display 110 or both side surfaces of the lower slider, and form locking grooves (not shown) on the inner side surface of the housing 210 where the protrusions are locked.

[0063] Therefore, when the flexible display 110 or the lower slider 122 reaches a predetermined position, the protrusions (not shown) located on both side surfaces are locked in the locking grooves (not shown), so that the flexible display 110 or the lower slider 122 is not returned to its original position by the elastic force of the rotating means 140 without the user applying force to the flexible display 110.

[0064] Conversely, when the user moves the flexible display 110 in the opposite direction, the protrusion (not shown) locked in the locking groove (not shown) is disengaged, and thus the flexible display 110 is elastically returned to its original position by the elastic force of the rotating means 140. Here, although the configuration of the protrusion and the locking groove as described above is not shown, this is achievable in the present invention, and a generally known locking configuration of a slider can be applied, and the drawings and descriptions thereof for the detailed configuration are omitted.

[0065] The present invention is characterized in that the configuration of a video unit that outputs video of a portable terminal (mobile phone, electronic dictionary, notebook computer, PMP, navigation device, DMB) provides a wider screen through a flexible display than in the prior art. For this purpose, it includes the accommodation and support structure of the flexible display as described above, and proves that it is a configuration in which the above-described technology can be realized. In addition, the present invention can constitute various embodiments as described below based on the above-described technical idea.

[0066] FIG. 7 is a side sectional view showing a second embodiment of a flexible display device of a portable terminal according to the present invention.

[0067] According to FIG. 7, the second embodiment of the present invention can provide a screen wider than the screen provided by the flexible display of the above-described preferred embodiment. To explain this, the flexible display 110 having a length longer than the length of the housing 210 of the main body 200 divides the region located on the upper surface 212 of the housing 210 into a first surface a and a second surface b, and extends from the first surface a to one side and is drawn in and out inside the housing 210, and a first side a′, and a second side b′ that extends from the second surface b to the other side and is drawn in and out inside the housing 210.

[0068] Here, the first side a′ and the second side b′ are supported inside the housing 210 by separate support portions 130 and 140, respectively.

[0069] The first side a' is supported by the upper surface 212 and the inner upper surface 213 of the housing 210 by the first upper slider 121a and the first lower slider 122a respectively, and the second side b' is supported by the second upper slider 121b and the second lower slider 122b respectively. Also, the first side a' and the second side b' are respectively connected to different connecting means 130 and supported by the elastic force of the rotating means 140, or the both side ends of the flexible display 110 can be supported in a state of being rolled on the outer surface of the rotating means 140.

[0070] Figures 8 and 9 are plan views for explaining the operation of a second embodiment of a flexible display device for a mobile terminal according to the present invention.

[0071] According to Figures 8 and 9, the flexible display according to the present invention can, as shown in the figures, divide the portion exposed on the upper surface 212 of the housing 210 into a first surface a and a second surface b respectively. Here, the first side a' and the second side b' cannot be confirmed in Figure 8 in a state of being housed inside the housing 210. However, if the user pulls out the first side a' and the second side b', as described above, they are pulled out as shown in Figure 9 by the actions of the support portions 130, 140 and the upper sliders 121a, 121b and the lower sliders 122a, 122b, and are exposed so as to be extended to both sides of the first surface a and the second surface b respectively.

[0072] Therefore, the user can receive video service through a wider screen compared to the screen provided in the above-described preferred embodiment.

[0073] Figure 10 is a perspective view showing a general folder-type mobile terminal for comparatively explaining a third embodiment of a flexible display device for a mobile terminal according to the present invention.

[0074] According to FIG. 10, generally, in a folder-type mobile phone, as shown in the figure, a display 110 is provided in a folder 100a to output an image, and a keypad for user operation is provided in a main body 200. Such a folder-type mobile phone originally had to provide a small screen because the size of the folder itself was small. However, in the present invention, it is possible to implement a configuration as shown in FIG. 11 by using the support portions 130 and 140 and the sliders 121 and 122 and the flexible display 110 as described above.

[0075] FIGS. 11 and 12 are perspective views showing a third embodiment of a flexible display device for a mobile terminal according to the present invention. Here, according to FIGS. 11 and 12, in the folder-type mobile phone of the present invention, the upper part can be described as a first folding part and the lower part can be described as a second folding part.

[0076] According to FIGS. 11 and 12, the third embodiment of the present invention includes a flexible display 110 that extends integrally from the upper side of the folder 100a to the lower side of the main body 200 in the folder-type mobile phone. Here, at the end portions between the upper side of the folder and the lower side of the main body 200, they are respectively housed in a state of being drawn into the inside of the main body 200 and the inside of the folder 100a. When the folder 100a rotates, both side portions of the flexible display housed inside the folder and the main body 200 are drawn out to provide a wider screen.

[0077] As shown in the figure, the present invention can also be formed to extend from the inside of the folder 100a to the main body 200. Furthermore, as shown in FIG. 12, the present invention also belongs to the scope of the technical idea of the present invention in that the flexible display 110 is provided outside the folder 100a and the main body 200.

[0078] FIGS. 13 and 14 are drawings showing a fourth embodiment of a flexible display device for a mobile terminal according to the present invention.

[0079] According to FIGS. 13 and 14, the fourth embodiment of the present invention shows a configuration in which one or more flexible display devices 110a, 110b are coupled inside the housing 210 and supported so as to be insertable and extractable by the support portions 130, 140 as described above. That is, in the present invention, the first flexible display 110a and the second flexible display 110b can be mutually fastened on one side and attached to one portable terminal device.

[0080] More specifically, the first flexible display 110a and the second flexible display 110b are in a state of being mutually fastened on one side as independent flexible displays. And either one of the first flexible display 110a and the second flexible display 110b is supported by the support portions 130, 140, the upper slider 122, or the lower slider 123 inside the housing 210 of each display device or the main body 200 as described above.
