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 a plurality of divided areas 34 partitioned by the partitioning part 32 and connected to each other by the fastening part 320. Thus, the shape of the rear cover 30 can be easily changed when the shape of the display module 10 is changed by the deformable member 20. Also, the rear cover 30 including the plurality of divided areas 34 can be easily integrated by the fastening part 320 and handled. 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 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, which will be described later in more detail.

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 upper and lower 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 is positioned. 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. [ 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 is a curved surface having a constant radius of curvature R in the left-right direction. Therefore, the fixing portion 24 is fixed to the display module 10 so as to protrude more from the center portion, so that the display module 10 can be more easily deformed.

The stopper member serves to fix the display panel 22 so as to maintain the state of the display panel 22 when the shape of the display panel 22 is changed.

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 in the left and right direction of the display module 10 are projected forward so that the display module 10 can be rotated with a constant radius of curvature R in the left and right direction. Then, the distance from the user's eyes to the display panel 12 is very fine even if there is no difference or difference in the center portion and the side portion. 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 a plurality of divided areas 34 divided and partitioned from each other. At this time, the dividing section 32 completely divides the neighboring divided region 34. Referring to FIG. 3, the rear cover 30 has a plurality of divided regions 34 formed separately from each other, which are connected to each other by a fastening portion 320 to integrate them. In the present embodiment, it is illustrated that the plurality of divided regions 34 are directly connected to each other by the fastening portions 320. However, the present invention is not limited thereto, and a plurality of divided regions 34 may be connected via another configuration located between the plurality of divided regions 34. [ Such an example will be described later in more detail with reference to FIG. 12 and FIG.

When the rear cover 30 includes a plurality of divided regions 34 formed separately from each other, the shape of the rear cover 30 is changed when the shape of the display module 10 is changed by the deformable member 20, Can be reduced. 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, as in the present embodiment, if the rear cover 30 includes a plurality of divided regions 34, it can be deformed by applying a relatively small force so as to deform one of the 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.

For example, as described above, when the display module 10 is deformed into a curved surface having a predetermined curvature radius R in the left-right direction, the divided portion 32 has a shape extending in the vertical direction intersecting the left- . 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, the divided region 34 divided by the division unit 32 may be extended in the vertical direction. The divided region 34 has a body portion 34a forming a gentle curved surface and forming an outer frame and a fixing portion 34a for fixing the frame portion 16 located at both ends in the vertical direction of the body portion 34a. Lt; RTI ID = 0.0 > 34b. ≪ / RTI > The frame portion 16 and the fixed end 34b can be fixed by the first fixing member 36. [ Thus, the divided region 34 is fixed to the frame portion 16 by the fixed end 34b formed at both ends in the vertical direction intersecting the deformation direction. Thus, by fixing the both ends in the vertical direction, it can be easily deformed corresponding to the force applied in the lateral direction.

4 and 5, the structure of the fixed end 34b in the display device 100 according to the present embodiment and the fixing structure of the fixed end 34b and the frame portion 16 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.

The fixed end 34b is moved toward the display module 10 side (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 main body portion 34a, As shown in Fig. The fixed end 34b is formed in parallel with the second frame part 16b, and can be stably fixed to the second frame part 16b. The main body portion 34a can be positioned relatively far away from the display module 10 and a sufficient space can be provided between the main body portion 34a and the display module 10 so that the support member 20, . However, the present invention is not limited thereto, and its structure can be variously modified.

The fixed end 34b of each of the divided regions 34 may be formed with a protruding portion P at a side portion thereof so as to overlap the fixed end 34b of the adjacent divided portion 34. [ The projection P formed at the fixed end 34b of one of the divided regions 34 overlaps with the fixed end 34b of the adjacent divided region 34. [ A threaded hole 340c is formed in the projection P formed at the fixed end 34b of the one divided region 34 and a portion of the adjacent divided region 34 overlapping the projection P at the corresponding position And a corresponding screw hole 340d is formed in the portion. And a screw hole 340b is formed at the position of the corresponding second frame portion 16b. By fastening the first fixing member 36 (e.g., a screw) to the screw holes 340b, 340c, and 340d, the two adjacent divided regions 34 are fixed to the second frame portion 16b can do. As a result, the two divided regions 34 spaced apart from each other can be stably fixed to the frame portion 16. The upper and lower ends of the divided region 34 can be firmly fixed to the frame portion 16 with a simple structure by the screw coupling structure. Although the first fixing member 36 is shown to be fixed to the supporting member 14 through the frame portion 16, the present invention is not limited thereto. Accordingly, the first fixing member 36 is fixed only to the frame portion 16 and is not fixed to the supporting member 14, and various modifications are possible.

At this time, the portion where the screw hole 340c for fastening the first fixing member 36 is formed on the protrusion P of the fixed end 34b is concave (that is, protruded toward the display module 10) ). When the first fixing member 36 is fastened to the screw holes 340b, 340c and 340d, the surface of the fixed end 34b where the first fixing member 36 is not positioned and the surface of the first fixing member 36 Plane can be positioned on the same plane. As a result, it is possible to prevent the first fixing member 36 from being seen from the appearance.

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 constant radius of curvature R in the lateral direction of the display module 10, the divided regions 34 extend and / or the intervals of the divided portions 32 become large. The screw holes 340b, 340c and 340d are elongated in the left and right direction of the display module 10 so as to flexibly cope with the width variation of the divided region 34 and / or the divided 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. Referring back to FIG. 3, in the present embodiment, the plurality of divided regions 34 have the same width. 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 are used as described above, the rear cover 30 can be formed using the plurality of divided regions 34 formed in the same process, thereby simplifying the manufacturing process. However, the present invention is not limited thereto, and it is also possible to use the divided regions 34 having different widths.

Both ends of the divided region 34 (more specifically, the body portion 34a) in the left and right direction can be fixedly connected to each other by the fastening portion 320. 6 and 7, the fixing structure of the body portion 34a by the fastening portion 320 will be described in more detail. 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.

Referring to FIGS. 6 and 7, each of the divided regions 34 (more precisely, the body portion 34a) may be formed with a fastening portion 320 to be fastened to a neighboring divided region 34. 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 321 is formed on one side of the first divided region 341a And a second fastening portion 322 is formed on one side of the second divided region 342a adjacent thereto. Accordingly, the first divided region 341a and the second divided region 342a can be fastened to each other by the first and second fastening portions 321 and 322.

In this embodiment, the first fastening portion 321 protrudes from one side of the body portion 34a toward the second divided region 342a and may have a fastening hole 321d. More specifically, the first fastening portion 321 includes a first projecting portion 321a projecting from the one side adjacent to the second division region 342a toward the display module 10 and a second projecting portion 321b projecting from the first projecting portion 321a And an overlapping portion 321b that extends from the first projecting portion 321a so as to overlap with the two-divided region 342a. A plurality of fastening holes 321d are formed in the overlapping portion 321b at regular intervals. And an extended portion 321c that is bent from the end of the overlapping portion 321b and extends rearward or toward the second divided region 342. [

By the first projecting portion 321a, the overlapping portion 321b can be extended to cover a portion of the second divisional region 342a at a position where the overlapping portion 321b does not overlap the second divisional region 342a. The overlapping portion 321b allows the second fastening portion 322 to be fastened by the fastening hole 321d. When the distances between the first and second divided regions 341a and 342a are different from each other, the overlapping portion 321b also functions to prevent the gap between the first and second divided regions 341a and 342a from being recognized from the outside. The extended portion 321c serves to support the second divisional region 342a to prevent the second divisional region 342 from hitting toward the overlapping portion 321b. For example, the end of the extended portion 321c may be in contact with and support the second divided region 342a.

The second fastening portion 322 includes a second projecting portion 322a projecting from the end adjacent to the first partitioning portion 341a toward the display module 10 and a second projecting portion 322b extending from the second projecting portion 322a, 322d formed in positions corresponding to the latch portions 322b, 321d. More specifically, the latch portions 322b and 322c include a first portion 322b extending from the second projecting portion 322a toward the display module 10, a second portion 322b extending from the first portion 322b, And a second portion 322c formed in a direction away from the display module 10 in an oblique direction.

The distance between the outer edges of the latch portion at the first end (i.e., the portion adjacent to the display module 10 in the latch portions 322b and 322c) where the first portion 322b and the second portion 322c are connected (That is, the distance between the outer edge of the first portion 322b and the outer edge of the second portion 322c) is relatively small, and the second end opposite to the first end The distance between the outer edge of the first portion 322b and the outer edge of the second portion 322c is a second width D2 that is larger than the first width D1 in the first portion 322b and the second portion 322a) Lt; / RTI > And the distance between the outer edge of the first portion 322b and the outer edge of the second portion 322c may gradually increase from the first end toward the second end.

At this time, the first width D1 may be smaller than the width D of the fastening hole 321d, and the second width D2 may be equal to or larger than the width D of the fastening hole 321d. The width D of the fastening hole 321d may be larger than the thickness D3 of the first portion 322b. And the second width D2 may be larger than the width D of the fastening hole 321d.

The latch portions 322b and 322c of the second fastening portion 322 are pushed and inserted into the fastening holes 321d of the first fastening portion 321 so as to insert the latching portions 322b and 322c of the first fastening portion 321, The first divided area 341a and the second divided area 342a can be fixed. At this time, a force is applied to the display module 10 in a state where the second division area 322 is positioned on the rear side of the first division area 321. 7A, since the first width D1 of the latch portions 322b and 322c is equal to or smaller than the width D of the fastening hole 321d, the latch portions 322b, 322c can easily enter into the fastening holes 321d. As shown in FIG. 7 (b), when a force is applied to the latch portions 322b and 322c so as to penetrate the fastening holes 321d, the second portion 322c is brought close to the first portion 322b The distance between the second portion 322c and the first portion 322b is narrowed and the latch portions 322b and 322c pass through the fastening holes 321d. After the second portion 322c passes through the fastening hole 321d, the second portion 322c recovers the second width D2 away from the first portion 322b. The second portion 322c is located in the overlapping portion 321b of the first fastening portion 321 and the latch portions 322b and 322b are positioned at the same position because the second width D2 is larger than the width D of the fastening hole 321d. 322b are prevented from falling out of the fastening holes 321d. Since the thickness D3 of the first portion 322b is smaller than the width D of the fastening hole 321d, the first portion 322b can move left and right with a predetermined clearance in the fastening hole 321d do.

Since the first part 322b can be moved by a predetermined distance in the fastening hole 321d after the fastening, the first divided area 341a and the second divided area 342a are stably fixed to each other, The distance between the first divisional area 341a and the second divisional area 342a is made to be closer or closer to each other. This makes it possible to cope flexibly with the distance between the divided regions 34 and the width of the divided portion 32.

Since the first fastening part 321 and the second fastening part 322 are fastened to each other to fix and connect the plurality of divided areas 34, the rear cover 30 can be integrated into one structure. 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 341 or the second fastening portion 342 may be located at the inner edge thereof. One of the first and second fastening portions 341 and 342 is located at both sides of the central divided region 343a located in the center and the center divided region 343a and the divided region 34 located at the outermost position The first fastening part 341 may be positioned at one side edge and the second fastening part 342 may be positioned at the other side edge. Thus, the plurality of divided regions 34 can be connected to each other.

Then, the rear cover 30 can be assembled by fastening the divided regions 34 in order from the outermost divided region 34 and then fastening the middle divided region 343c. In this case, the manufacturing process can be simplified, and the divided regions 34 can be symmetrical with respect to the central divided region 343c to improve the structural stability, and the plurality of divided regions 34 can be formed by the family mold, The rear cover 30 can be easily manufactured.

The divided areas 34 of the rear cover 30 should be made of a material that is strong enough to form the rear surface of the display device 100 and is light and easy to deform. The divided regions 34 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 321 and 322 constituting the fastening portion 320 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 have. Thus, the structure and the manufacturing process can be simplified as compared with the use of the separate fastening portion 320. However, the present invention is not limited thereto, and various modifications are possible, for example, the fastening portion 320 is formed on the divided region 34 after being manufactured so as to form a separate portion from the divided region 34.

A change in the shape of the display device 100 will be described in more detail with reference to FIG. 8 is a view for explaining a shape change of a display device according to an embodiment of the present invention. 8 is a cross-sectional view taken along the line VIII-VIII of FIG.

At this time, the central portion of the deformable member 20 is fixed by the fixing member 24a, and the deformable member 20 may be positioned more protruding from the center portion than the left and right edges toward the rear surface. Accordingly, the shape of the display module 10 can be more easily deformed.

When the user gives an instruction to change the shape, the deformable member 20 operates by the element driving the deformable member 20 in the panel driving unit. For example, in this embodiment, when the temperature of the deforming portion 22 is increased by flowing a current through the deforming portion 22 of the deformable member 20, the length of the deformable portion 22 formed of the shape memory alloy is reduced, Thereby giving a force to retract the central portion while projecting the left and right edge portions of the body 10. Then, as shown in FIG. 8 (b), the display module 10 is transformed into a curved surface having a uniform curvature radius R as a whole in the left-right direction, so that the user's immersion feeling can be further improved. At this time, the rear cover 30 fixed to the display module 10 is also deformed to have a curved surface. Since the divided region 34 is connected by the fastening portion 320 to easily adjust the distance between the divided regions 34 or the distance between the divided portions 32 as described above, It can change. When the display device 100 is deformed to a desired shape, the stopper member can be used to maintain this state.
