1 and 2, the display apparatus 100 according to the present embodiment includes a display module 10 in which an image is implemented and a variable member 20 that changes the shape of the display module 10. . And it may include a rear cover 30 that covers the back of the display module 10. This will be explained in more detail.

The display device 100 refers to a device that is displayed on a screen so that data, images, and the like can be viewed, and may include various types of televisions, computer monitors, cell phones, and e-books.

The display module 10 includes a display panel 12 that substantially implements an image, a support member 14 positioned on the rear surface of the display panel 12 to support the display panel 12, and a support member 14 It is fixed to the display panel 12 may include a panel driver (not shown) for providing a signal for driving. In addition, although not separately illustrated in the drawings, a frame portion surrounding the edges of the display panel 12 and the support member 14 may be further positioned.

In this embodiment, the display panel 12 is a panel having various structures and methods capable of realizing an image, and having a flexible characteristic and having a shape that can be changed by the variable member 20.

As an 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-emissive display panel using a principle in which light is generated while electrons and holes are combined in an organic thin film by flowing an electric current in a fluorescent or phosphorescent organic thin film. The organic light emitting display panel has various advantages such as a bright and clear picture quality, no limitation due to viewing angle, and low power consumption. In particular, since it can be manufactured by laminating an organic thin film, it has excellent flexible properties. However, the present invention is not limited thereto, and various display panels 12 having various structures and methods may be applied.

The support member 14 is located on the rear side of the display panel 12 to support the display panel 12. In addition, a panel driving unit and a variable member 20 that drive the display panel 12 and are fixed to the rear surface of the support member 14 may be located on the rear surface of the support member 14. Accordingly, the support member 14 has a strength capable of being supported and fixed by the display panel 12, the panel driving unit, and the variable member 20, and the shape may change when the shape of the display panel 12 changes. So it can have flexible properties, elasticity, and the like. In addition, the support member 14 may have a coefficient of thermal expansion similar to that of the display panel 12 to prevent thermal stress or the like from occurring.

For example, in this embodiment, the support member 14 may include a composite material such as reinforced plastic. A composite material is a material that artificially combines two or more types 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) and glass fiber reinforced plastic (GFRP). Then, while having light and flexible characteristics by plastic, it can have high strength, elasticity, and excellent wear resistance by reinforcing materials of various fiber types. The support member 14 may be composed of a single composite material layer, or a plurality of composite material layers may be stacked for excellent strength.

The support member 14 may be fixed to the rear surface of the display panel 12 using an adhesive (eg, double-sided tape) or the like. However, the present invention is not limited thereto, and the display panel 12 and the support member 14 may 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 that provide signals for driving the panel. The panel driving unit may be fixed to the support member 14 by a bracket (not shown) or the like, for example, when the bracket is fixed to the support member 14 only in 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 various modifications such as a part or all of the panel driving unit may be located outside the display module 10. The panel driving unit of this embodiment may include wiring, elements, and the like for driving the variable member 20.

In addition, a frame portion (not shown) protecting the edges of the display panel 12 and the support member 14 may be further positioned. The frame portion protects the display panel and the support member 14, while allowing the rear cover 30 to be fixed by a fixing member (not shown). Since the shape of the frame portion, the fixing structure of the frame portion and the rear cover 30, etc., various structures and methods can be applied, detailed description thereof will be omitted.

A variable member 20 capable of changing the display panel 12 is located on the rear surface of the display module 10 (more specifically, the support member 14 ). In this embodiment, the variable member 20 is located between the first part 22 and the support member 14 and the first part 22 fixed to the support member 14 of the display module 10, and both sides It includes a second portion 24 whose ends are fixed to both ends of the first portion 22. In addition, a guide member 28 supported by the inner portion of the first portion 22 may be further included. In this embodiment, the shape of the display module 10 may be changed by changing a distance (hereinafter referred to as “connection length”) between both ends of the second portion 24 fixed to the first portion 22. The shapes of the first and second portions 22 and 24 will be described in more detail.

In this embodiment, the variable member 20 may be formed to be elongated along one direction (eg, left and right directions of the display apparatus 100). In addition, when the connection length of the second portion 24 of the variable member 20 is shortened, both end portions of the first portion 22 are changed to protrude. Then, the display module 10 can be bent as a whole to have a constant radius of curvature in the left and right directions (reference numeral R in FIG. 4, hereinafter the same). When the shape of the display module 10 is changed as described above, the distance from the user's eyes to the display panel 12 is at a very fine level even if there is no difference or difference in the center portion and the edge portion. Accordingly, the immersion of the user can be improved. However, the present invention is not limited to this. Therefore, the deformed shape of the variable member 20 may vary, and accordingly, the deformed shape of the display module 10 may vary.

In addition, in the drawing, the variable member 20 is illustrated as an example that is located in the upper portion of the display module 10 and located in the lower portion of the display module 10. It is considered that deformation of the upper and lower edge portions of the display module 10 may not easily occur when only one of the variable members 20 is located in the central portion. When a plurality of the variable members 20 are provided as described above, the shape of the display module 10 can be uniformly changed as a whole. However, the present invention is not limited to this, and it is possible to reduce the cost and simplify the structure by having only one variable member 20. Alternatively, three or more variable members 20 may be provided in consideration of the case where the display module 10 is enlarged. Of course, various other modifications are possible.

At this time, the second portion 24 may have a shape (for example, a wire shape) that extends along the left and right directions of the display module 10. The connection length of the second portion 24 may be changed by various energy (ie, thermal energy, electrical energy, mechanical energy).

For example, when the second portion 24 is made of a material whose shape changes with temperature, the second portion 24 is provided by changing the temperature of the second portion 24 by providing thermal energy or electrical energy. Can change the length of the connection. In this case, the second portion 24 may include a shape memory alloy. The shape memory alloy is an alloy that uses shape memory and superplastic properties that appear in austenite-martensitic transformation metals, and has different shapes depending on temperature. The second portion 24 is connected to an element or the like that drives the variable member 20 in the panel driver, the temperature is adjusted, and accordingly, the connection length may be changed. As described above, when the connection length of the second portion 24 is changed by thermal energy or electrical energy including a shape memory alloy, the structure is simple and easy to apply, and noise is not generated when the display module 10 is deformed.

As another example, along with the panel driving unit, the connection length of the second portion 24 may be changed by mechanical energy provided to a separate driving unit (not shown, for example, a motor) that supplies mechanical energy. That is, a part of the second part 24 is fixed to the motor, so that the length of the connection of the second part 24 may change due to the part of the second part 24 being wound or unwound on the rotation axis of the motor by rotation of the motor. Can. In this case, the second portion 24 does not stretch or hardly stretch under various conditions and may be made of a material having a large yield strength. This is because when the second portion 24 is extended, it may be difficult to precisely deform the connection length, and more mechanical energy must be provided. For example, the second portion 24 may include materials such as metal steel wire (eg, stainless steel wire), aramid fiber, and carbon steel wire. In addition, the second portion 24 may be made of various materials. The driving unit such as a motor providing mechanical energy may have various configurations capable of changing the shape of the variable member 20. As described above, when the driving unit of the motor or the like changes the shape of the variable member 20 using mechanical energy, the variable member 20 can be easily deformed, and the degree of deformation, deformation time, etc. of the variable member 20 can be precisely controlled. can do.

The second portion 24 may have a diameter of 0.5 mm to 10 mm. If the diameter of the second portion 24 is less than 0.5 mm, problems such as breaking or deformation of the second portion 24 may occur when receiving energy from a driving unit or the like. When the diameter of the second portion 24 exceeds 10 mm, problems may arise such as increased mechanical energy required to change the connection length of the second portion 24, increasing costs, and complicated configuration. However, the present invention is not limited to this, and the second portion 24 may have various diameters.

In addition, in the drawing, although only one second portion 24 is provided for each first portion 22, various modifications such as a plurality of second portions 24 are possible.

As described above, when the connection length of the second portion 24 changes, the shape of the first portion 22 changes, and the first portion 22 applies a force to the display module 10 to cause the display module 10 to The shape also changes to respond. As described above, the first portion 22 is a portion that changes the shape of the display module 10 by being deformed under the force of the second portion 24. Accordingly, the first portion 22 may include a material having flexibility and excellent strength. In addition, the material constituting the first portion 22 may be a light material to lighten the display device 100.

In one example, the first portion 22 may include a single material or a plurality of 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 first portion 22 may be formed of various materials. In addition, the first portion 22 may have a band shape that extends while having a constant width (W). Accordingly, it is possible to more effectively provide force to the display module 10. However, the present invention is not limited to this, and the first portion 22 may have various shapes.

At this time, the first portion 22 is fixed to the central portion of the display module 10 (more specifically, the support member 14) so as not to be moved, and both ends of the first portion 22 are not fixed but freely Located. Accordingly, the shape of the first portion 22 can be changed more freely.

Here, the central portion of the first portion 22 is fixed non-movably by the central fixing portion 26a. At this time, the first distance L1 between the center of the first portion 22 and the center of the support member 14 is greater than the distance L2 between the end of the first portion 22 and the end of the support member 14 It can be big. For example, the first portion 22 may have a curved shape such that the central region of the first portion 22 has a more protruding round shape toward the rear of the display module 10. Then, the display module 10 can be more easily deformed when the display module 10 is entirely deformed to a constant radius of curvature R by changing the connection length of the second portion 24.

The central fixing portion 26a includes a bracket 260a separating the first portion 22 and the second portion 24 while separating the first portion 22 from the support member 14, and the bracket 260a or A fastening member 262a for fastening the first part 22 and the support member 14 may be included.

Here, the bracket 260a serves to make the distance between the first portion 22 and the support member 14 larger in the center than the end. Accordingly, as described above, the first portion 22 may be maintained in a more protruding state toward the rear surface of the display module 10. In addition, since the second portion 24 is located between the bracket 260a and the support member 14, the bracket 260a separates the first portion 22 and the second portion 24 from each other, so that the first portion 22 The distance between the and the second portion 24 (that is, the first distance L1) has a relatively large value. The larger the area between the first portion 22 and the second portion 24, the larger the bending moment, and thus the shape change of the first portion 22 according to the change in the connection length of the second portion 24 It is easy to implement. Accordingly, in the present embodiment, the first portion 22 and the second portion 24 are increased by relatively increasing the first distance L1 between the first portion 22 and the second portion 24 in the central portion. The area can be increased, and accordingly, the shape change of the first portion 24 can be more easily implemented.

For example, the thickness T1 of the bracket 260a (ie, the first distance L1 between the first portion 22 and the second portion 24) may be 10 mm to 50 mm. When the thickness T1 of the bracket 260a exceeds 50 mm, the thickness of the display device 100 becomes thick and structural stability of the first portion 22 may be deteriorated. In addition, when the thickness T1 of the bracket 260a is less than 10 mm, the bending moment is not large, and thus large energy may be required to deform the first portion 22. However, the present invention is not limited thereto, and the thickness T1 of the bracket 260a may vary depending on the size of the screen and the radius of curvature R of the screen.

In addition, the fastening member 262a may have various configurations and methods to fasten the first part 22 and the support member 14 at the central portion. In one example, the femme nut 14a is positioned on the support member 14, and the fastening member 262a can be fastened to the femme nut 14a by penetrating through the first portion 22 and/or the bracket 260a. Thereby, the first part 22 can be fixed to the support member 14 simply and easily. However, the present invention is not limited to this, and various methods and structures may be used as the fixing structure of the support member 14 and the side portion 28b.

In this embodiment, it is positioned at a predetermined distance D1 from the end of the first portion 22 and the side edge of the display module 10. In one example, the distance D1 between the end of the first portion 22 and the side edge of the display module 10 may be 1 mm to 30 mm. When the gap D1 exceeds 30 mm, it may be difficult for the first portion 22 to apply force evenly to the edge of the display module 10. When the gap D1 is less than 1 mm, when the first portion 22 is deformed, the first portion 22 protrudes to the outside of the display module 10, which is a problem or another component is located so that deformation is unlikely to occur. Can. However, the present invention is not limited to this, and the interval D1 may vary depending on the size of the screen and the radius of curvature R of the screen.

In the second portion 24, both ends are fixed to both ends of the first portion 22, respectively, and a connection length is formed between both ends of the second portion 24. At this time, both end portions of the second portion 24 may be fixed to both end portions of the first portion 22 by the end fixing portions 26b, respectively. That is, the end fixing portion 26b includes a first end fixing portion 261b that fixes one end of the second portion 24 to one end of the first portion 22 and the other side of the second portion 24. It may include a second end fixing portion (262b) for fixing the end to the other end of the first portion (22).

The end fixing portion 26b can fix the second portion 24 to the first portion 22 in various ways. In one example, the end fixing portion 26b has a thickness smaller than the bracket 260a of the central fixing portion 26a, and the second portion 24 may be embedded therein to penetrate a portion of the end fixing portion 26b. have. Or, by forming a hole at the end of the first portion 22, passing the end of the second portion 24 through the hole, and then filling the hole using an adhesive or a sealing material, etc. to end the second portion 24 Can be fixed to the end of the first portion 22. However, the present invention is not limited to this, and various other methods may be applied.

Accordingly, the distance between the end of the first portion 22 and the end of the second portion 24 has a second distance L2 smaller than the above-described first distance L1. Thereby, the bending moment according to the change in the connection length of the second portion 24 is increased, so that the first portion 22 can be easily deformed.

In addition, between the end of the second portion 24 fixed to the end fixing portion 26b and the display module 10 (or the thickness of the end fixing portion 26b) may be spaced apart by a third distance L3. This is to prevent the end of the second portion 24 from interfering with the display module 10. Particularly, when the shape of the display module 10 changes according to a change in the connection length of the second portion 24, the gap between the second portion 24 and the display module 10 becomes closer, which is considered. As an example, the third distance L3 may be 1 mm to 10 mm. When the third distance exceeds 10 mm, the thickness of the display device 100 may be unnecessarily increased. If the third distance L3 is less than 1 mm, the end of the second portion 24 may interfere with the display module 10. However, the present invention is not limited to this, and various modifications are possible.

In this embodiment, the second portion 24 is fixed to the first portion 22 at a portion located between the central fixing portion 26a and the end fixing portion 26b, so that the second portion 24 and the display module 10 are fixed. An anti-interference fixing portion 26c to prevent interference may be located. The anti-interference fixation portion 26c includes a first anti-interference fixation portion 261c positioned between the central fixation portion 26a and the first end fixation portion 261b, and a central fixation portion 26a and a second end portion. A second interference prevention fixing portion 262c positioned between the fixing portions 262b may be included.

The distance between the first portion 22 and the second portion 24 by the anti-interference fixing portion 26c may be gradually reduced from the central fixing portion 26a toward the anti-interference fixing portion 26c. Accordingly, the distance between the second portion 24 and the display module 10 gradually increases from the central fixing portion 26a toward the first anti-interference fixing portion 261c, and then the first anti-interference fixing portion 261c ) Toward the end fixing portion 261b may be gradually reduced. Similarly, accordingly, the distance between the second portion 24 and the display module 10 gradually increases from the central fixing portion 26a toward the second anti-interference fixing portion 262c, and then the second anti-interference fixing portion ( It can be gradually reduced from 262c toward the end fixing portion 262b.

At this time, the section that constitutes the vicinity of the center of the second part 24 and moves away from the rear surface of the display module 10 while pointing toward the end of the second part 24 is called the center section (S11, S12), and the center A section located outside the sections S11 and S12 and facing toward the end of the second portion 24, the section from which the distance from the rear surface of the display module 10 approaches may be referred to as the outer sections S21 and S22.

At this time, the central section (S11, S12), the first central section (S11) between the central fixed portion (26a) and the first anti-interference fixed portion (261c), the central fixed portion (26a) and the second interference prevention high It may include a second central section (S12) between the government (262c). The first central section S11 and the second central section S12 may have structures that are symmetrical to each other based on the central portion where the central fixing portion 26a is located. This is to prevent problems such as warping of the display module 10 due to uniform bending moments acting on both sides.

Similarly, the outer sections S21 and S22 include the first outer section S21 between the first anti-interference fixing section 261c and the first end-fixing section 261b, and the second anti-interference fixing section 262c. A second outer section S22 between the second end fixing portions 262b may be included. The first outer section S21 and the second outer section S22 may have structures that are symmetrical to each other based on the central portion where the central fixing portion 26a is located. This is to prevent problems such as warping of the display module 10 due to uniform bending moments acting on both sides.

As described above, the second portion 24 may have, for example, a shape similar to the letter “W”. This shape is to maximize the bending moment while preventing problems caused by interference.

In this case, a ratio of the length of the first central section S1 (or the second central section S12) to the total length L of the first portion 22 may be 0.1 to 0.2. When the length ratio is less than 0.1, the size of the bending moment proportional to the area between the first portion 22 and the second portion 24 may be reduced. If the length ratio exceeds 0.2, the second portion 24 may interfere with the display module 10. However, the present invention is not limited to this, and the ratio may vary.

As described above, the distance between the second part 24 and the display module 10 is gradually increased in the central sections S11 and S12 by the interference prevention fixing part 26c, so that the second part 24 is It is possible to prevent the deformation by interfering with the display module 10. In addition, by optimizing the length ratio of the central section (S11, S12) it is possible to transmit a large bending moment to the first portion (22).

At this time, the area between the first portion 22 and the second portion 24 in the central section S11, S12 is called the first area A1, and the first portion 22 in the outer section S21, S22. When the area between the and the second portion 24 is referred to as the second area A2, the ratio of the first area A1 to the second area A2 may be 16 to 400. This takes into account that the bending moment is proportional to the sum (A1 + A2) of the first area (A1) and the second area (A2), so that the interference between the display module 10 and the second part 24 does not occur. It is determined that the sum of the first area A1 and the second area A2 has the largest possible value. However, the present invention is not limited thereto, and the above-described ratio may vary depending on the area of the display module 10, the radius of curvature R, and the like.

The above-described central fixing portion 26a, end fixing portion 26b and anti-interference fixing portion 26c may be made of various materials. These are easy to fix and may be made of a material that does not damage the second part 24, for example, may be made of a material such as a resin (eg, polyphenylamide). However, the present invention is not limited to this.

In addition, the first portion 22 may be movably fixed by a guide member 28 fixed to the support member 14. Accordingly, the first portion 22 can be moved while preventing deformation such as sagging of the first portion 22.

The guide member 28 includes an upper portion 28a spaced apart from the support member 14 at a predetermined space, and a side portion 28b bent from the upper portion 28a and adjacent to the support member 14. Includes. The side portion 28b is fixed to the support member 14 by the fastening member 28c. For example, a pam nut (not shown) or the like may be located on the support member 14, and a guide member 28 is fastened by fastening a fastening member 28c such as a screw to a fastening hole of the pam nut and the side portion 28b. ) And the supporting member 14 can be fixed. In this way, it is possible to fasten simply and easily by using a pamnut and a screw. However, the present invention is not limited to this, and various methods and structures may be used as the fixing structure of the support member 14 and the side portion 28b.

As described above, since the distance between the first portion 22 and the display module 10 increases toward the center portion, the height of the side portion 28b of the guide member 28 also increases toward the center portion. According to this, the first portion 22 can be freely moved to the left and right while being effectively supported by the guide member 28.

For the entire length L of the first portion 22, the ratio (D2/D4) of the distance D2 at which each guide member 28 is spaced from each end of the first portion 22 is 0.2 to 0.4 days Can. This ratio is determined so that both sides of the first portion 22 can be firmly fixed so as not to hit. However, the present invention is not limited to this.

And the rear cover 30 is located on the rear surface of the display module 10 and the variable member 20. The rear cover 30 protects the display module 10, the panel driver, and the like with external impact while providing a space where a configuration such as a panel driver is located. In addition, the rear cover 30 serves to prevent the internal configuration from being seen from the outside by covering the panel driving unit and the like, and to improve the appearance. In one example, the rear cover 30 is made of a curved surface as a whole to sufficiently secure a space and improve appearance. In this embodiment, the rear cover 30 may have a material, a structure, and the like that can correspond to the shape change of the display module 10.

The shape change of the display device 100 will be described in more detail with reference to FIG. 4. 4 is a view for explaining the shape change of the display device according to an embodiment of the present invention. In FIG. 4, the illustration of the rear cover 30 is omitted for clarity.

As shown in FIG. 4A, the display module 10 has a flat plate shape in the absence of other manipulations.

At this time, the first portion 22 of the variable member 20 is fixed to the central region is not movable by the central fixing portion 26a, the central portion than the left and right edges may be located in a more protruding form toward the rear. . According to this, the shape deformation of the display module 10 can be made more easily. Guide members (reference numeral 28 in FIG. 2) are located on both sides of the first portion 22 to support the first portion 22 while allowing the first portion to move.

When the user gives a command to change the shape of the display module 10, energy is supplied to the second portion 24 by a driving unit such as a panel driving unit or a motor, so that the connection length is shortened. That is, the connection length of the second portion 24 made of a shape memory alloy is shortened by providing electrical energy or thermal energy, or the connection length is shortened by winding the second portion 24 on a rotating shaft by providing mechanical energy. Decrease. Then, the shape is changed so that the end region protrudes while the first portion 22 is bent as a whole, thereby changing the shape of the display module 10.
