1 to 3, a display device 100 according to the present embodiment includes a display module 10 in which an image is implemented, a deformable member 20 that changes the shape of the display module 10, And a rear cover 30 located on the rear surface of the module 10. At this time, the rear cover 30 includes an opening portion 310 having an opening portion 312 and a cover portion 320 connected to the opening portion 310. And the opening portion 310 may be covered or clogged by the cover member 40 so as not to be seen from the outside. Accordingly, when the shape of the display module 10 is changed by the deformable member 20, the shape of the rear cover 30 can be easily changed and the appearance can be kept beautiful. In addition, by attaching the parts or the like necessary for the display device 100 to the cover member 40, the structure of the display device 100 can be simplified and the productivity of the assembling process can be improved. This will be explained in more detail.

The display module 10 includes a display panel 12 that substantially implements an image, a support member 14 that is positioned on the rear surface of the display panel 12 and supports the display panel 12, (Not shown) which is fixed to the display panel 12 and provides a signal for driving the display panel 12 and a display panel 12 which surrounds the side surfaces of the display panel 12 and the support member 14, And may include a frame portion 16.

In the present embodiment, the display panel 12 is a panel having various structures and systems capable of implementing an image, and having a flexible characteristic, the shape of which can be changed by the deformable member 20.

For example, the display panel 12 may be an organic light emitting display panel using an organic light emitting diode (OLED). The organic light emitting display panel is a self-luminous display panel that uses a principle that a current is generated in a fluorescent or phosphorescent organic thin film to combine electrons and holes in the organic thin film to generate light. The organic light emitting display panel has various advantages such as a bright and clear image quality, no limitation by the viewing angle, and low power consumption. In particular, since the organic thin film can be produced by laminating it, the flexible property is excellent. However, the present invention is not limited thereto, and various display panels 12 having various structures and systems can be applied.

The support member 14 is disposed on the rear surface of the display panel 12 to support the display panel 12. A panel driving part and a deformable member 20 which are fixed to the rear surface of the supporting member 14 by driving the display panel 12 may be positioned on the rear surface of the supporting member 14. [ The supporting member 14 has a strength that can be supported and fixed to the display panel 12, the panel driving unit and the deformable member 20, and the shape can be changed when the shape of the display panel 12 is changed Elasticity, and the like. In addition, the support member 14 may have a thermal expansion coefficient similar to that of the display panel 12 in order to prevent thermal stress or the like from occurring.

For example, in this embodiment, the support member 14 may comprise a composite material such as reinforced plastic. Composite material is a material that artificially combines two or more kinds of materials to have excellent properties. For example, in this embodiment, the support member 14 may include reinforced plastics such as carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP), and the like. Then, it is possible to have high strength, elasticity, and excellent abrasion resistance by a reinforcing material of various fiber form while having light and flexible characteristics by plastic. The support member 14 may be composed of a single composite material layer or may be formed by stacking a plurality of composite material layers for superior strength.

The support member 14 may be fixed to the rear surface of the display panel 12 using an adhesive (for example, a double-sided tape). However, the present invention is not limited thereto, and the display panel 12 and the supporting member 14 can be fixed by various other methods.

The panel driver fixed to the rear surface of the support member 14 includes a circuit board (not shown) including various wires, elements, and the like to provide a signal for driving the panel. Such a panel driving unit may be fixed to the supporting member 14 by a bracket (not shown) or the like. For example, when the bracket is fixed to the supporting member 14 only at the central portion to change the shape of the display panel 12 The required force can be minimized. However, the present invention is not limited thereto, and it is needless to say that a part or all of the panel driving unit is located outside the display module 10, and the like.

At this time, the panel driving unit of the present embodiment may include wiring, devices, and the like for driving the deformable member 20. [

The frame portion 16 is located along the edge of the display panel 12 and the support member 14. [ The frame portion 16 functions to secure the display panel 12 and the support member 14 and protect the edges of the display panel 12 and the support member 14. [ The rear cover 30 covering the rear surface of the display panel 12 may be fixed to the frame portion 16. 3, the illustration of the frame portion 16 is omitted for the sake of brevity and clarity.

More specifically, the frame portion 16 of the present embodiment includes a first frame portion (reference numeral 16a in Fig. 5, hereinafter the same) for covering the edge of the display module 10 and a second frame portion 16b protruding from the first frame portion 16a, (16b in Fig. 5, hereinafter the same) positioned on the rear surface of the first frame 10, as shown in Fig. The edges of the display module 10 can be securely protected by the first and second frame portions 16a and 16b and the rear cover 30 can be stably secured to the display module 10 by the second frame portion 16b . The fixing structure of the frame portion 16 and the rear cover 30 will be described later in more detail with reference to FIGS. 4 and 5. FIG. However, the present invention is not limited thereto, and the shape and position of the frame portion 16 may be variously modified.

On the rear surface of the support member 14, a deformable member 20 capable of deforming the display panel 12 (or the display module 10) is located. The variable member 20 may have various configurations and schemes that can change the shape of the display module 10. [

In this embodiment, the deformable member 20 may include a deformable portion 22 and a fixing portion 24 for fixing the deformable portion 22 to the supporting member 14, for example. A stopper member (not shown) may be positioned at both ends of the fixing part 24. [

The deforming portion 22 can be applied to various structures and systems that can change the length, shape, etc. by a temperature change, an electric signal, or the like. For example, the deformable portion 22 may include a shape memory alloy and may have a wire shape extending along the lateral direction of the display module 10. The shape memory alloy is an alloy that utilizes shape memory and super plasticity appearing in a metal that undergo austenite-martensitic transformation and has a different shape depending on the temperature. The deformable part 22 is connected to an element or the like driving the variable member 20 in the panel driving part so that the temperature is adjusted and the length of the deformable part 22 is changed to change the shape of the display panel 12 or the display module 10 . When the shape memory alloy is used as the deformation portion 22, the structure is simple and easy to apply, and noise is not generated when the display module 10 is deformed.

The deforming portion 22 is fixed to the fixing portion 24 and the fixing portion 24 to which the deforming portion 22 is fixed can be fixed to the supporting member 14. [ The fixing portion 24 may have a shape extending in the lateral direction while the deformable portion 22 is positioned inside. The fixing portion 24 may include a material that can change its shape when the shape of the display panel 12 changes while supporting the deforming portion 22. [ Accordingly, the fixing portion 24 may have a single or multiple layers including a composite material, for example, reinforced plastic (CFRP, GFRP, etc.). However, the present invention is not limited thereto, and it is needless to say that the fixing part 24 can be formed of various materials.

At this time, the fixing member 24a located at the central portion of the fixing portion 24 has a certain height, and the fixing portion 24 and the supporting member 14 may have a larger interval than the central portion. For example, the fixing portion 24 may be positioned on the supporting member 14 such that the central portion of the fixing portion 24 has a rounded shape that protrudes more toward the rear of the display module 10. [

When the central portion of the fixing portion 24 is positioned in a rounded shape more protruding than the other portions, the display panel 12 can be more easily deformed when the display panel 12 is deformed by the deforming portion 22. [ . That is, in the present embodiment, both side ends of the display panel 12 are protruded using the deformable member 20 so that the display panel 12 has a curved surface in the left-right direction. Therefore, the fixing portion 24 can be fixed to the display module 10 so as to protrude more from the central portion, so that the display module 10 can be more easily deformed.

The stopper member serves to fix the display panel 12 so as to maintain the state of the display panel 12 when the shape of the display panel 12 changes.

When the temperature is raised by applying a current to the deformation portion 22 by the panel driving portion, both ends of the deformation portion 22 can be bent forward as the length of the deformation portion 22 is worn. Both ends of the display module 10 in the left and right direction are projected forward so that the display module 10 can be curved so as to have a curvature in the lateral direction. Then, the distance from the user's eyes to the display panel 12 becomes fine even if the center portion and the side portion do not have a difference or there is a difference. Accordingly, the immersion feeling of the user can be improved.

In such a deformed state, the stopper member can be used to hold the display panel 12 in a deformed state. In this case, since current is not continuously supplied to maintain the deformed state of the display panel 12, power consumption can be minimized.

In order to change the display panel 12 back to its original state, the state of the stopper member is returned to the original state or the current supply is removed to return the deformed portion 22 to its original length, Change.

In the above-described embodiment, the shape of the display panel 12 is set to change as the length of the deformed portion 22 decreases when the temperature rises. However, the present invention is not limited thereto. Therefore, the length of the deformation portion 22 can be set to be long when the deformation portion 22 rises in temperature, and various other deformation is possible. Although the deformable portion 20 using the shape memory alloy is used as the deformable member 20, the deformable portion 22 may be of various types and structures such as a motor and a spring member.

The structure and the manner of the fixing part 24 and the stopper member may also be variously applied to various structures and methods. The position, arrangement, and the like of the stopper member can be variously modified according to the structure and the manner thereof.

In this embodiment, the display panel 12 is deformed so as to have a curved surface having a constant radius of curvature R in the lateral direction, but the present invention is not limited thereto. Therefore, it is also possible to deform it so as to have a curved surface in the vertical direction, or to deform it into various other shapes.

In the present embodiment, the deformable member 20 is located on the rear surface of the support member 14, but the present invention is not limited thereto. Thus, it is possible to display the display 12 at various locations, such as between the display panel 12 and the support member 14, within the support member 14, between the support member 14 and the back cover 30, It is sufficient to provide a force for changing the shape of the panel 12.

The rear cover 30 is located on the rear surface of the display module 10. The rear cover 30 protects the display module 10, the panel driving unit, and the like by an external impact while providing a space for the structure of the panel driving unit and the like. In addition, the rear cover 30 covers the panel driving unit and the like to prevent the internal structure from being seen from the outside and to improve the appearance. For example, the rear cover 30 may be formed as a curved surface as a whole to secure a sufficient space and improve the appearance.

In this embodiment, the rear cover 30 has a structure capable of coping with a change in the shape of the display module 10 when the shape of the display module 10 is changed. Accordingly, the display module 10 is protected and the appearance is maintained even when the shape of the display module 10 is changed without hindering the shape change of the display module 10. [

To this end, the back cover 30 in this embodiment includes an opening portion 310 having an opening and a cover portion 320 connected to the opening portion 310. The cover portion 320 may include a plurality of divided regions 34 divided and partitioned from each other. The opening portion 310 and the plurality of divided regions 34 constituting the cover portion 320 can be completely divided by the dividing portion 32. [ The opening portion 310 and the plurality of divided regions 34 divided by the division portion 32 can be connected to each other and integrated by the fixing member 330 as shown in Fig.

As described above, when the rear cover 30 includes the opening portion 310 having the opening portion 312 and the cover portion 320 including the plurality of divided regions 34, the display module The shape of the rear cover 30 can be reduced when the shape of the rear cover 30 changes. That is, when the rear cover 30 is formed of a single plate having a uniform thickness without the partition 32, a large force is required because the shape of one plate must be changed as a whole. In addition, since a single plate is used as a reference, the displacement is also increased and it is difficult to uniformly apply force to all the parts. On the other hand, if the back cover 30 includes the opening portion 310 having the opening portion 312 as in the present embodiment, the opening portion 310 can be easily deformed with a small force. And the cover portion 320 constituting the remainder can be deformed by applying a relatively small force to the extent that the one partition region 34 can be deformed by the plurality of divided regions 34. [ Further, since the displacement of each of the divided regions 34 is small, it is possible to cope with the shape change more easily, and uniform shape change is possible. However, the present invention is not limited thereto. It is also possible that the cover portion 320 located on both sides of the opening portion 310 is not divided but only one region.

For example, as described above, when the display module 10 is deformed into a curved surface having a curvature in the left-right direction, the divided portion 32 may have a shape extending in the vertical direction intersecting with the left-right direction. When the display module 10 is deformed into a curved surface, a bending force acts on the rear cover 30 in the left and right directions. Accordingly, in the present embodiment, the divided portion 32 is formed so as to extend vertically in the vertical direction, and the plurality of divided regions 34 are arranged in the left-right direction. As a result, the width of the divided region 34 to which the bending force is applied is relatively small, so that the divided region 34 can be easily deformed.

At this time, each of the opening portion 310 and the plurality of divided regions 34 may be formed to extend from the upper edge to the lower edge of the display device 100. Fixed ends 310b and 34b for fixing the frame portion 16 to the opening portion 310 and portions corresponding to the upper and lower edges of the plurality of divided regions 34 may be formed. For example, the opening 310 may include a main body 310a having an opening 312 and a fixed end 310b positioned at both ends of the main body 310a. Each of the divided regions 34 has a gently curved surface and includes a main body portion 34a for forming an outer frame and a fixed portion for fixing the frame portion 16 located at both ends in the vertical direction of the main body portion 34a. Lt; RTI ID = 0.0 > 34b. ≪ / RTI > The fixed ends 310 and 34b of the frame portion 16 and the opening portion 310 and the divided portion 34 can be fixed by the fastening member 36 have. The opening portion 310 and the divided region 34 are fixed to the frame portion 16 by the fixed ends 310b and 34b formed at both ends in the vertical direction intersecting with the respective deforming directions. Thus, by fixing the both ends in the vertical direction, it can be easily deformed corresponding to the force applied in the lateral direction.

The structure of the fixed ends 310b and 34b in the display device 100 according to the present embodiment and the structures of the fixed ends 310b and 34b and the frame portions 16b and 34b are described with reference to FIGS. Will be described in more detail. 4 is an enlarged perspective view of the portion A shown in Fig. 2, which is an enlarged perspective view of a fixed end portion of the rear cover, and Fig. 5 is a sectional view cut along the line IV-IV in Fig. In Figs. 4 and 5, the fixed end 34b corresponding to the two adjacent divided regions 34 is shown. However, the following description can be applied not only to the adjacent two divided regions 34 but also to the fixed ends 310b of the adjacent opening portions 310 and the fixed ends 34b of the divided regions 34. [

The fixed end 310b of the opening portion 310 is positioned closer to the display module 10 than to the body portion 310a (more precisely, to the second frame of the frame portion 16 located on the rear surface of the display module 10) (Toward the portion 16b). Similarly, the fixed end 34b is directed toward the display module 10 (more precisely toward the second frame portion 16b of the frame portion 16 located on the rear surface of the display module 10) than the body portion 34a, As shown in Fig.

The fixed ends 310b and 34b of the opening portion 310 and the divided region 34 are formed in parallel with the second frame portion 16b so as to be stably fixed to the second frame portion 16b . The main body portions 310a and 34a can be positioned relatively far from the display module 10 so that the support member 20 and the panel drive portion are positioned between the main body portions 310a and 34a and the display module 10 Provide enough space to be able to. However, the present invention is not limited thereto, and its structure can be variously modified.

The fixed ends 310b and 34b of the opening portion 310 and the divided region 34 are formed with protrusions (not shown) on the side portions so as to overlap with the fixed ends 310b and 34b of the adjacent divided region 34 or the opening portion 310 P may be formed. The protrusions P formed on the fixed ends 34b of one of the divided regions 34 overlap with the fixed ends 310b and 34b of the adjacent divided regions 34 or the opening portions 310. [ A screw hole 340c is formed in the projection P formed at the fixed end 34b of the one division region 34 and the adjacent division region 34 or the adjacent division region 34 overlapping the projection P at the corresponding position And a corresponding screw hole 340d is formed in the portion of the opening portion 310. [ And a screw hole 340b is formed at the position of the corresponding second frame portion 16b. By fastening the fastening member 36 (for example, a screw or a bolt member) to the screw holes 340b, 340c and 340d, two adjacent divided regions 34 or neighboring divided regions 34, The portion 310 can be fixed to the second frame portion 16b together. Accordingly, the opening portion 310 and the divided region 34 can be stably fixed to the frame portion 16. The upper and lower ends of the opening portion 310 and the divided region 34 can be firmly fixed to the frame portion 16 with a simple structure by the screw coupling structure. Although the fastening member 36 is illustrated as being fixed to the support member 14 through the frame portion 16, the present invention is not limited thereto. Therefore, various modifications are possible, for example, the fastening member 36 is fixed only to the frame portion 16 and is not fixed to the support member 14. [

At this time, the portion where the screw hole 340c for fastening the fastening member 36 is formed on the protruding portion P of the fixed ends 310b and 34b is recessed (that is, protruded toward the display module 10) ). As a result, when the fastening members 36 are fastened to the screw holes 340b, 340c, and 340d, the surfaces of the fastening ends 310b and 34b, on which the fastening members 36 are not positioned, As shown in Fig. As a result, it is possible to prevent the fastening member 36 from being seen in an apparent manner.

At this time, the screw holes 340b, 340c, and 340d may be elongated in the left-right direction of the display module 10. When the display module 10 is deformed into a curved surface having a curvature in the lateral direction of the display module 10, the opening portion 310 and / or the divided region 34 are extended and / or the interval between the divided portions 32 is increased. The screw holes 340b, 340c and 340d are elongated in the left and right direction of the display module 10 to flexibly cope with the width changes of the opening portion 310, the partitioning region 34 and / or the partitioning portion 32 .

However, the present invention is not limited thereto. The fixing structure of the rear cover 30 and the frame portion 16 may be variously modified. For example, a variety of methods such as fitting with a fixing structure of the rear cover 30 and the frame portion 16, an adhesive and the like can be used.

2 and 3, the opening portion 310 of the present embodiment constitutes a central portion of the rear cover 30, and a cover portion 320 (for example, a first portion And a cover portion 320 (for example, a second cover portion) may be located on the other side of the opening portion 310. As shown in Fig. The cover portion 320 located on one side of the rear cover 30 is divided into a plurality of divided regions 34 and the cover portion 320 located on the other side of the rear cover 30 is divided into a plurality of divided regions 34 do. This will be explained in more detail.

In this embodiment, the cover portion 320 located on one side of the rear cover 30 and the cover portion 320 located on the other side may be positioned symmetrically with respect to each other. That is, the cover portion 320 located at one side of the rear cover 30 and the cover portion 320 located at the other side may include the same number of divided regions 34 having the same or similar width. Then, the left and right sides of the display device 100 at the time of deformation may be symmetrically deformed to improve the structural stability. However, the present invention is not limited thereto, and the shape and structure of the cover part 320 located at one side of the rear cover 30 and the cover part 320 located at the other side may be different.

In the figure, each of the cover portions 320 has a plurality of divided regions 34 having the same width W31. Here, the same width includes not only the case where they are completely physically identical but also the width which can be judged to be the same in consideration of process errors and the like. If the plurality of divided regions 34 having the same width W31 are used as described above, the rear cover 30 can be formed by using the plurality of divided regions 34 formed in the same process, . The divided region 34 of the same width W31 may be positioned adjacent to the opening portion 310. [ And the outer divided portion 34 connected to the frame portion 16 may have a smaller width W32 than the divided portion 34 adjacent to the opening portion 310. [ In this case, when the display module 10 is deformed, the width of the area having the largest displacement can be made small so that deformation can be more easily caused.

However, the present invention is not limited thereto, and the width of the plurality of divided regions 34 can be variously modified. For example, the width of the divided area 34 may gradually become smaller toward the end in the lateral direction. Other variations are possible.

The opening portion 310 (in particular, the body portion 310a of the opening portion 310) is constituted by the edge portions 3110, 3120, 3130, and 3140 surrounding the opening portion 312 so as to have the opening portion 312 therein . For example, when the display panel 12 has a roughly rectangular shape, the opening portion 310 includes an upper edge portion 3110, a lower edge portion 3120, a side edge portion 3130, And may include an edge portion 3140. As a result, it is possible to have a rectangular frame shape so as to have a rectangular opening portion 310 therein. The upper edge portion 3110 and the lower edge portion 3120 may have fixed ends 310b formed or connected to the frame portion 16, respectively. However, the present invention is not limited thereto, and the shape of the opening portion 310 or the shape and arrangement of the edge portions 3110, 3120, 3130, and 3140 may be variously modified.

In the present embodiment, the opening portion 310 is provided at the center portion of the rear cover 30, so that the force required for the deformation can be greatly reduced. A portion of the rear cover 30 where the rear cover 30 is not formed due to the opening 312 is not required to be deformed by the opening 312, The required strength can be further reduced. Since the opening 312 is covered with a separate cover member 40, it is possible to prevent problems such as deterioration of the appearance due to the opening 312. The cover member 40 will be described later in more detail.

The upper and lower portions 3110 and 3120 of the opening 311 and the lower edge 3120 of the opening 312 are formed with slits 3112 and 3112 extending upward and downward, 3122 are formed. The slits 3112 and 3122 are formed by partially removing the upper and lower edge portions 3110 and 3120 so that the opening portion 310 can be uniformly deformed with a smaller force when the rear cover 30 is deformed. do.

The slits 3112 and 3122 may be partially formed in the width direction of the upper and lower edge portions 3110 and 3120. In one example, the slits 3112 and 3122 can be extended to have a length of 0.2 to 0.8 times the widths W4 and W5 of the upper and lower edge portions 3110 and 3120. If the ratio is less than 0.2 times, the effect of reducing the force by the slits 3112 and 3122 may not be large. If the ratio exceeds 0.8 times, the strength of the upper and lower edge portions 3110 and 3120 may be lowered. However, the present invention is not limited thereto, and the lengths of the slits 3112 and 3122 can be variously modified.

The slits 3112 and 3122 may be arranged at regular intervals in the longitudinal direction of the upper and lower edge portions 3110 and 3120 at regular intervals. Then, even if the opening portion 310 has a wide overall width W1, it can be easily deformed by a small force. The total width W1 of the opening 310 may mean the distance between the outermost edges of the edges 3110, 3120, 3130, and 3140 constituting the opening 310.

A part of the edge portions 3110, 3120, 3130 and 3140 located at the upper and lower portions of the opening 312 (i.e., the upper edge portion 3110 and the lower edge portion 3120) The concave portions 3114 and 3124 can be formed. The concave portions 3114 and 3124 are formed by removing a part of them from the central portions of the upper and lower edge portions 3110 and 3120 so that the cover member 40 covering the opening portion 312 is formed in the concave portion 3114, and 3124 to the display module 10 (more precisely, the support member 14). This will be described in more detail later. The recesses 3114 and 3124 reduce the force required to deform the opening portion 310 similarly to the slits 3112 and 3122 and allow the opening portion 310 to be more uniformly deformed.

The entire width W1 of the opening portion 310 may be larger than the width W2 of the cover portion 320 located on one side of the rear cover 30 or the cover portion 320 located on the other side. Then, the opening portion 310 is formed to have a sufficient overall width W1, so that the force required for deformation of the rear cover 30 can be reduced. The entire width W1 of the opening portion 310 may be larger than the widths W31 and W32 of the divided region 34. [ The width W31 and the width W32 of the divided area 34 can be reduced to minimize the force required to deform the rear cover 30 by forming the opening 310 with a sufficient overall width W1.

The widths W4, W5, W6 and W7 of the edge portions 3110, 3120, 3130 and 3140 of the opening portion 310 correspond to the width W2 of the cover portion 320 located on one side or the other side of the rear cover 30, , And may be smaller than the widths W31 and W32 of the divided region 34. [ If the widths W4, W5, W6 and W7 of the edge portions 3110, 3120, 3130 and 3140 of the opening portion 310 are relatively small, the opening portion 312 can be formed with a sufficient area, It is possible to minimize the force required for the deformation of the base 30.

However, the present invention is not limited thereto. The width W1 of the opening portion 310 and the widths W4, W5, W6 and W7 of the edge portions 3110, 3120, 3130 and 3140 of the opening portion 310, The width W2 of the cover portion 320 located on one side or the other side of the rear cover 30 and the widths W31 and W32 of the divided region 34 can be variously modified.

Both ends of the opening portion 310 (more specifically, the left and right ends of the main body portion 310a and the plurality of divided regions 34 (more specifically, the main body portion 34a) The fixing structure of the body portions 310a and 34a by the fixing member 330 will be described in more detail with reference to FIGS. 6 to 8. FIG.

FIG. 6 is a perspective view showing a main body portion of the divided region shown in FIG. 3, and FIG. 7 is a sectional view cut along the line VII-VII in FIG. And FIG. 8 is a plan view schematically showing a fastening hole and a first fixing member formed in the divided region shown in FIG.

6 and 7, each of the divided portions 34 and the opening portions 310 (more precisely, the body portions 310a and 34a) overlap with the adjacent divided portions 34 to form a fastening portion (1321, 1322). The fixing member 330 is fastened to the fastening portions 1321 and 1322 of the adjacent two divided regions 34 or the adjacent divided regions 34 and the opening portion 310 to form two adjacent divided regions 34, Or the neighboring divided region 34 and the opening portion 310 are movably fixed. The opening portion 310 and the divided portion 34 are movably fixed to each other in the drawings and description. However, in the case where each cover portion 320 is configured as a hinge region, the opening portion 310 and the cover portion 320 are movably fixed to each other.

For example, when two adjacent divided regions 34 are referred to as a first divided region 341a and a second divided region 342a, a first joined portion 1321 is formed on one side of the first divided region 341a And a second fastening part 1322 may be formed on one side of the second divided area 342a adjacent thereto. In the divided regions 34 and the openings 310 adjacent to each other, any one of the first fastening portions 1321 and the second fastening portions 1322, One of the first fastening portion 1321 and the second fastening portion 1322 is located at one side of the portion 310. [ In the drawing, for example, when the divided region 34 and the opening portion 310 are adjacent to each other, a first fastening portion 1321 is formed on one side of the divided region 34, and one side And the second fastening portion 1322 is positioned on the second fastening portion 1322. The two divided regions 34 or neighboring divided regions 34 and the opening portions 310 can move with respect to each other by fastening the fixing member 330 to the first and second fastening portions 1321 and 1322 .

In this embodiment, the first fastening portion 1321 is provided with the second divided region 342a or the second divided region 342b from one side of the first divided region 341a (or the divided region 34 adjacent to the opening portion 310, And may have a fastening hole 1321d. More specifically, the first fastening portion 1321 includes a first protruding portion 1321a protruding from the one side adjacent to the second partitioning region 342a or the opening portion 310 toward the display module 10, And a first overlapping portion 1321b that extends from the portion 1321a to extend from the first projecting portion 1321a so as to overlap with the second partitioning portion 342a or the opening portion 310. [ A plurality of fastening holes 1321d are formed in the overlapping portion 1321b at regular intervals. Although not shown in the figure, it may further include an extending portion that is bent from the end portion of the overlapping portion 1321b and extends rearward.

The first overlapping portion 1321b can be extended by the first projecting portion 1321a so as to cover a part of the first overlapping portion 1321b while being spaced from the outer surface of the second division region 342a or the opening portion 310. [ The first overlapping portion 1321b allows the fixing member 330 to be fastened by the fastening hole 1321d. The first overlapping portion 1321b is formed such that the interval between the first and second division regions 341a and 342a or the first division region 341a and the opening portion 310 are spaced apart from each other It also plays a role of preventing the user from being recognized by the user.

The second fastening portion 1322 includes a second projecting portion 1322a projecting from the end adjacent to the first partitioning portion 341a toward the display module 10 and a second projecting portion 1322b projecting from the second projecting portion 1322a toward the second sub- And a second overlapping portion 1322b that extends toward the center or inward of the opening portion 310 or overlaps the first overlapping portion 1321b. The second overlapping portion 1322b overlaps the first overlapping portion 1321b by the second protruding portion 1322a. In one example, the second overlapping portion 1322b may overlap in parallel with the first overlapping portion 1321b and may be positioned in close contact with the first overlapping portion 1321b.

The fixing member 330 is fastened to the first and second overlapping portions 1321b and 1322b, which overlap with each other. More specifically, the fixing member 330 includes a first fixing member 332 protruding from the second overlapping portion 1322b and penetrating the fastening hole 1321d, and a second fastening member 332 formed on the first fastening portion side (more specifically, And a second fixing member 334 inserted into the first fixing member 332 and fixed to the first fixing member 332.

The first fixing member 332 may protrude from the second overlapping portion 1322b and penetrate the fastening hole 1321d of the first overlapping portion 1321b. In this case, the first fixing member 332 may be a nut member having a first screw 332a formed on the inner surface thereof. For example, the first fixing member 332 may be formed of a press-fitting nut or the like.

In the drawing, the first fixing member 332 has a structure integrally formed with the second overlapping portion 1322b. The second overlapping portion 1322b in which the first fixing member 332 is integrally formed can be easily manufactured by forming the first fixing member 332 together in the process of forming the division region 34. [ When the first fixing member 332 is integrally formed in the second overlapping portion 1322b (that is, when the first fixing member 332 is formed while forming a part of the second overlapping portion 1322b), the fixing stability of the first fixing member 332 Can be improved. However, the present invention is not limited thereto, and it is also possible that the first fixing member 332 is separately manufactured and then attached or assembled to the second overlapping portion 1322b.

At this time, the first fixing member 332 may protrude more toward the display module 10 than the first overlapping portion 1321b of the first fastening portion 1321. That is, the first height H1 of the first fixing member 332 may be greater than the thickness T of the first overlapping portion 1321b. The first height H1 may be a length measured between the end of the first fixing member 332 adjacent to the side of the display module 10 from the side of the second overlapping member 1322b adjacent to the side of the display module 10 . The end of the fixing member 332 adjacent to the side of the display module 10 is positioned closer to the side of the display module 10 than the side of the first overlapping portion 1321b adjacent to the display module 10. [ The portion of the first fixing member 332 corresponding to the second height H2 corresponding to the difference between the first height H1 and the thickness T is larger than the first overlapping portion 1321b of the display module 10, As shown in FIG.

As a result, the second fixing member 334 (particularly, the head portion 3344 of the second fixing member 334) fastened to the first fixing member 332 does not contact the first overlapping portion 1321b, And may be positioned so as to have a certain gap (a gap corresponding to the second height H2) and the overlapping portion 1321b. Thereby, the first fixing member 332 and the first overlapping portion 1321b are positioned so as not to cause friction with each other. The shape of the display module 10 (or the display panel 12) is changed by the deformable member 20 so that the interval between the first divisional area 341a and the second divisional area 341b or the division area 34 The first overlapping portion 1321b can freely move without being interfered with by the second fixing member 334 when the gap between the opening portion 310 and the opening portion 310 is increased or decreased.

The ratio H2 / H1 of the second height H2 of the portion of the first fixing member 322 protruding from the first overlapping portion 1321b to the first height H1 of the first fixing member 332, May be 0.2 to 0.4. If the ratio H2 / H1 is less than 0.2, it may be difficult to sufficiently prevent the interference of the first fixing member 332 with respect to the first overlapping portion 1321b because the second height H2 is relatively small. If the ratio H2 / H1 exceeds 0.4, the second height H2 is relatively large, so that the structural stability of the rear cover 30 may be deteriorated, and noise may be generated while being vibrated by an external impact or the like. Alternatively, the second height H2 may be between 0.1 mm and 1 mm. If the second height H2 is less than 0.1 mm, the second height H2 is relatively small and it may be difficult to sufficiently prevent interference of the first fixing member 332 with respect to the first overlapping portion 1321b. If the second height H2 exceeds 1 mm, the second height H2 is relatively large, so that the structural stability of the rear cover 30 may be deteriorated, and noise may be generated while being vibrated by an external impact or the like.

However, the present invention is not limited thereto, and the size of the second height H2, the ratio of the second height H2 to the first height H1, and the like can be variously modified.

The second fixing member 334 fastened to the first fixing member 332 is moved toward the first overlapping portion 1321b of the first fastening portion 1321 or toward the first fixing member 332 from the solar cell module 10 side And is fixed to the first fixing member 332. For example, the second fixing member 334 may be a bolt member fastened to the first fixing member 332, which is a nut member.

More specifically, the second fixing member 334 includes a screw portion 3342 formed with a second screw 334a engaged with the first screw 332a of the first fixing member 332, And may include a head portion 3344 having an area larger than the threaded portion 3342. The screw portion 3342 is a portion for fastening with the first fixing member 332. [ The head portion 3344 has a vertical width and / or a horizontal width larger than the fastening holes 1321d of the first overlapping portions 1321b so that the first overlapping portions 1321b provided with the fastening holes 1321d are overlapped So that it can be fixed between the portion 1322b and the head portion 3344.

The first width W11 of the fastening hole 1321d may be larger than the width W12 of the first fixing member 332 in this embodiment. Here, the width may mean a length measured along the left-right direction of the display module 10. [ Since the first width W11 of the fastening hole 1321d is larger than the second width W12 of the first fastening member 332 as described above, the first fastening member 332 moves left and right in the fastening hole 1321d .

8, the fastening hole 1321d includes a first hole S1 having a shape corresponding to one side of the first fixing member 334 and a second hole S1 having a shape corresponding to the other side of the first fixing member 334. [ A second hole S2 and a spare hole S3 located between the first hole S1 and the second hole S2. The spare hole portion S3 has a third width W13 which is a width corresponding to the moving distance of the first fixing member 334 while having a vertical width corresponding to the width W of the first fixing member 334 in the vertical direction, As shown in FIG. At this time, the difference between the first width W11 and the second width W12 corresponds to the third width W13. The fastening hole 1321d is provided with the clearance hole S3 so that the first fixing member 334 can move left and right as far as the third width W13.

In the drawing, a case where the plane shape of the first fixing member 334 is circular is exemplified. In this case, the first hole S1 may have a semicircular shape, the second hole S2 may have a semicircular shape, and the third hole S3 may have a rectangular shape. However, the present invention is not limited thereto, and the shapes of the first through third holes S1, S2, and S3 may be variously modified in consideration of the shape and the like of the first fixing member 334.

For example, the ratio W11 / W12 of the first width W11 of the fastening hole 1321d to the second width W12 of the first fixing member 334 may be 1.2 to 1.8. If the ratio W11 / W12 is less than 1.2, the lateral movement distance may not be sufficient and the shape of the rear cover 30 may not change smoothly when the display module 10 changes shape. If the ratios W11 and W12 exceed 1.8, the coupling hole 1321d may have an unnecessarily large width to reduce the structural stability, and the coupling hole 1321d may be visible from the outside, It may be necessary to increase the size of the antenna. Alternatively, a value obtained by subtracting the second width W12 of the first fixing member 334 from the first width W11 of the fastening hole 1321d (i.e., the third width W13 of the third hole portion S3) And may be 0.1 mm to 10 mm. If the third width W13 is less than 0.1 mm, the moving distance to the right and left is insufficient, so that the shape of the rear cover 30 may not be smoothly changed when the display module 10 is changed in shape. If the third width W13 exceeds 10 mm, the fastening hole 1321d may have an unnecessarily large width to reduce the structural stability, and the fastening hole 1321d may be seen from the outside, It may be necessary to increase the size of the antenna.

However, the present invention is not limited thereto, and the first width W11, the second width W12, the third width W13, and the ratios thereof may be variously modified.

Since the first fixing portion 332 can be moved by a predetermined distance in the fastening hole 1321d after the fastening as described above, the first divided portion 341a and the second divided portion 342a, or the divided portion 34, The first and second divided regions 341a and 342a or between the divided region 34 and the opened portion 310 at the time of changing the shape of the display module 10 while the portions 310 are stably fixed to each other. Make it farther or closer. This makes it possible to flexibly cope with the distance between the divided region 34 and the opening portion 310 and the width of the divided portion 32.

At this time, the first and second fixing members 332 and 334 are fastened to each other to fix and connect the plurality of divided regions 34 and the opening portions 310, so that the rear cover 30 can be integrated into one structure . If the bolt member and the nut member are used for the first and second fixing members 332 and 334, the fastening structure can be made more simple and robust.

At this time, in the divided region 34 located at the outermost periphery, a fixing portion (for example, a screw hole) for fixing the frame portion 10 to the outermost edge can be located. And the first fastening portion 1321 or the second fastening portion 1322 may be located at the inner edge. One of the first and second fastening portions 1321 and 1321 is positioned at each side edge of the opening portion 310 located at the center portion and the divided portion 34 located at the outermost position with the opening portion 310 is positioned at one side edge, The first fastening portion 1321 may be positioned at one side edge and the second fastening portion 1322 may be positioned at the other edge of the divided region 34. [ Thus, the plurality of divided regions 34 can be connected to each other.

The first fastening portion 1321 is located on the inner edge of the divided region 34 located at the outermost position and the second fastening portion 1322 is located on the opposite side edges of the opening portion 310. In the divided region 342, The second fastening part 1322 is positioned at the outer edge of the first fastening part 34 and the first fastening part 1321 is positioned at the center edge. Then, the rear cover 30 can be assembled by fastening the divided regions 34 in order from the outermost partition 34, and then fastening the opening portions 310 together. Thus, the manufacturing process can be simplified, and the cover portions 320 on both sides of the opening portion 310 can have a symmetrical structure to improve structural stability, and a plurality of divided regions 34 can be formed by the family mold The rear cover 30 can be easily manufactured.

The opening portion 310 and the cover portion 320 of the rear cover 30 should be made of a material that is light and easily deformable to the extent that the rear surface of the display device 100 can be configured. The opening portion 310 and the cover portion 320 may include various metals or resins and the like. As the metal, aluminum which is light and suitable for shape deformation can be used, and rubber can be used as the resin. The first and second fastening portions 1321 and 1322 may be formed so as to have an integral structure with the divided region 34 so as to constitute a part of the divided region 34 or the opening portion 310 in this embodiment. The structure and manufacturing process of the divided region 34 or the opening portion 310 can be simplified. However, the present invention is not limited to this, and it is also possible that the fastening portions 1321 and 1322 are formed on the divided region 34 or the opening portion 310 after being manufactured so as to form a separate portion from the divided region 34 or the opening portion 310 It can be variously modified. In this embodiment, the first and second overlapping portions 1321b and 1322b, to which the fixing members 332 and 334 are fastened, are inserted into the main body portion 34a of the divided region 34 or the main body portion And the first and second protruding portions 1321a and 1322a are spaced apart from each other by a predetermined distance. However, the present invention is not limited thereto, and various modifications are possible, such as not including the first and second projecting portions 1321a and 1322a, and not including the step.

The opening 312 of the rear cover 30 may be covered or clogged by the cover member 40 so that it can not be seen from the outside and contaminants or the like from the outside can be prevented from passing through the inside. At this time, the cover member 40 is fixed to the display module 10 (more precisely, the support member 14), and may not be fixed to the rear cover 30. Thus, even if the shape of the rear cover 30 is deformed, interference by the cover member 40 can be prevented. Although the cover member 40 is not fixed to the rear cover 30 in the present embodiment, the present invention is not limited thereto. Therefore, even if the shape of the rear cover 30 is changed by fixing the cover member 40 to the rear cover 30 movably with a predetermined clearance, the cover member 40 prevents the shape change of the rear cover 30 . Other variations are possible.

At this time, the cover member 40 may merely serve to cover the opening 312. Alternatively, parts or the like necessary for the display device 100 may be mounted on the cover member 40 as in this embodiment. It is not necessary to add a separate cover member 40 for covering the rear cover 30 having the opening 312 in the visual field when parts and the like necessary for the display device 100 are mounted on the cover member 40, The structure of the used part may be modified by the cover member 40 and used. Accordingly, the structure of the display device 100 can be simplified and the assembling process can be simplified.

For example, the cover member 40 of the present embodiment can constitute a speaker frame including a speaker 42 that generates sound. The structure of the cover member 40 will be described in more detail with reference to Fig. 9 together with Fig.

FIG. 9 is a schematic rear exploded perspective view of the display device shown in FIG. 2. FIG. 10 is a sectional view cut along the line X-X in Fig.

2, 9 and 10, the cover member 40 of the present embodiment includes a speaker 42 and a plate portion 44 provided with a speaker 42 and covering the opening portion 312. The cover member 40 includes a speaker 42 and a first bracket portion 46 located at the upper portion of the plate portion 44 and a speaker 42 and a second bracket 46 located at the lower portion of the plate portion 44. [ (48). ≪ / RTI >

The speaker 42 plays a role of emitting sound to the outside when the image is implemented in the display module 10. Various structures and systems known as the speaker 42 can be applied, and thus a detailed description thereof will be omitted. In this embodiment, the speaker 42 may include a first speaker 42a located at one side and a second speaker 42b located at the other side to be separated from the first speaker 42a. As a result, a more lively sound can be provided to the user. The first and second loudspeakers 42a and 42b are disposed on both sides of the first and second loudspeakers 42a and 42b such that the rear side distance of the first and second loudspeakers 42a and 42b is smaller than the front side distance of the first and second loudspeakers 42a and 42b. Can be formed to be inclined. For example, the first and second speakers 42a and 42b may have a parallelogram shape and the oblique directions may be opposite to each other. The first and second speakers 42a and 42b constitute a side portion of the cover member 40 constituting the speaker frame. The first and second speakers 42a and 42b face the front side from the rear side, Has a gradually widening shape, it may be superior in appearance and may have a large structural stability. However, the present invention is not limited thereto, and the first and second speakers 42a and 42b may have various shapes and arrangements.

The upper plate 44 is formed to connect the first and second speakers 42a and 42b so that the first speaker 42a and the second speaker 42b are located at both sides and substantially blocks the opening 312 .

The plate upper portion 44 may have a bent shape so that the first speaker 42a and the second speaker 42b can be stably positioned. That is, the plate upper portion 44 includes a front portion 442 positioned on the front surface of the first and second speakers 42a and 42b and a rear portion 442 protruding rearward from the front portion 442, A rear portion 444 that is coplanar with the rear surface of the front portion 442 and a side portion 446 that connects the front portion 442 and the rear portion 444.

Then, it is possible to cover the opening 312 with the parts necessary for the display device 100 while having the rear cover 30 having the opening 312, which is advantageous for deformation. For example, in this embodiment, the cover member 40 may constitute a speaker frame. Accordingly, it is possible to realize the display device 100 which is advantageous for deformation without any additional parts and which is excellent in appearance.

Since the cover portion 320 has a plurality of divided regions 34 defined by the dividing portions 32, the force required for deforming the shape of the rear cover 30 can be further reduced. Accordingly, power consumption for changing the shape of the display module 10 or the display device 100 can be minimized, and it is possible to uniformly deform the display module 10 or the display device 100 to have a desired shape. At this time, since the plurality of divided regions 34 are fixed in a state where they are connected to each other by the fixing member 330, the rear cover 30 can be integrated to simplify the structure and improve ease of handling.

At this time, if the bolt member and the nut member are used for the first and second fixing members 332 and 334, the fastening structure can be made more simple and robust. The width and height of the first and second fastening members 332 and 334 and the fastening hole 1321d are limited so that the shape of the rear cover 30 can be easily changed can do. The first and second fixing members 332 and 334 are disposed on the first and second overlapping portions 1321b and 1321b of the first and second fastening portions 1321 and 1322 overlapping with each other inside the outer surface of the rear cover 30 And 1322b so that the fastening holes 1321d and the like can be made invisible to the user even if the shape of the rear cover 30 changes.
