However, this disclosure may be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, fully conveying the concept of this disclosure to those skilled in the art, and this disclosure will be defined only by the appended claims.

[0054] The shapes, dimensions, ratios, angles, quantities, etc., illustrated in the accompanying drawings to describe the various exemplary embodiments disclosed herein are merely examples, and therefore, this disclosure is not limited thereto. Throughout this disclosure, the same reference numerals refer to the same components. Furthermore, detailed descriptions of well-known technologies may be omitted or simplified in this disclosure to avoid obscuring the subject matter. When terms such as "comprising," "having," "including," or "consisting of" are used in this disclosure, it should be understood that additional elements or steps may be included unless "only" is specifically used. Unless explicitly stated otherwise, when components are expressed in the singular, it is intended to also cover the plural form.

For example, when a structure is described as being "above," "below," "on top of," "below," "underneath," "adjacent to," "close to," or "adjacent to," "next to," or "adjoining" another structure, this description should be interpreted to include situations where the structures are in contact with each other and situations where a third structure is positioned or inserted between them. Furthermore, the terms "left," "right," "top," "bottom," "downward," "upward," "above," "below," etc., refer to any frame of reference.

[0057] When a device or layer is referred to as being "on" or "connected" to another device or layer, it includes situations where a device or layer is directly on or directly connected to another device or layer, or where another device or layer is inserted between two devices or layers.

[0058] Although the terms "first," "second," "A," "B," "(a)," and "(b)," etc., are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from others, and the substance, order, sequence, or number of the corresponding elements should not be limited by these terms. Therefore, in the technical sense of this disclosure, the first component mentioned below can be the second component.

[0059] Throughout this disclosure, the same reference numerals refer to the same components.

[0060] The dimensions and thicknesses of each component shown in the accompanying drawings are presented for ease of description and are not intended to limit this disclosure.

[0061] The term “at least one” should be understood to include any and all combinations of one or more of the related listed items. For example, “at least one of the first element, the second element, and the third element” means that the meaning covers all combinations of the three listed elements, any combination of any two of the three elements, and each individual element (the first element, the second element, or the third element).

[0062] Features of the various embodiments of this disclosure may be linked or combined with each other in part or in whole, and may interoperate with each other in various ways and be technically driven, as will be fully understood by those skilled in the art. Embodiments of this disclosure may be performed independently of each other, or may be performed together in an interdependent relationship.

[0063] Unless otherwise defined, the terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It will also be understood that terms (such as those defined in common dictionaries) should be interpreted as having a meaning consistent, for example, with their meaning in the context of the relevant field, and should not be interpreted in an idealized or overly formal sense unless expressly defined herein. For example, the terms “component” or “unit” can be applied, for example, to a single circuit or structure, an integrated circuit, a computational block of a circuit arrangement, or any structure configured to perform the described functions, as would be understood by one of ordinary skill in the art.

[0064] In the following description, exemplary embodiments will be described in detail with reference to the accompanying drawings.

[0065] In this disclosure, the term "display device" is used in a narrow sense to refer to display devices such as liquid crystal modules (LCMs), organic light-emitting diode (OLED) modules, and quantum dot modules, each including a display panel and a panel driving unit for operating the display panel. Additionally, the term can also refer to assemblies of electronic devices, assemblies, or equipment including LCMs, OLED modules, QD modules, etc., such as complete or final products including equipment displays for vehicles such as laptops, televisions, computer monitors, in-vehicle displays, or other forms of equipment displays for vehicles, as well as equipment display devices for mobile electronic devices such as smartphones or tablets.

[0066] Therefore, in this disclosure, the display device may include not only the display device itself in the narrow sense (such as LCM, OLED module, QD module), but also complete sets of devices that are application products or end-consumer devices, each including LCM, OLED module, QD module, etc.

[0067] Furthermore, in some cases, an LCM, OLED module, or QD module, including a display panel and a panel driving unit, can be referred to as a "display device" in the narrow sense, while an electronic device that is a complete product including an LCM, OLED module, or QD module can be referred to as a "complete assembly." For example, a display device in the narrow sense can include a liquid crystal (LCD), organic light-emitting diode (OLED), or quantum dot (QD) display panel and a source printed circuit board (PCB) that serves as a control unit for driving the display panel, while a complete assembly can also include a complete PCB that serves as a complete control unit electrically connected to the source PCB and controlling the entire assembly.

[0068] The display panels used in the embodiments of this disclosure may include all types of display panels, such as liquid crystal display panels, organic light-emitting diode (OLED) display panels, quantum dot (QD) display panels, and electroluminescent display panels, and are not limited to specific display panels with flexible substrates having an OLED display panel and a backplane support structure underneath, and bendable bezels. Furthermore, the display panels used in the embodiments of this disclosure are not limited to any particular shape or size.

[0069] For example, when the display panel is an organic light-emitting diode (OLED) display panel, it can include multiple gate lines and data lines, as well as pixels formed at the intersections of the gate lines and data lines. Additionally, it can be configured to include: an array comprising thin-film transistors as components for selectively applying voltage to each pixel; an organic light-emitting diode (OLED) layer on the array; and an encapsulation substrate or encapsulation layer disposed on the array to cover the organic light-emitting diode layer, etc.

[0070] The encapsulation layer can protect the thin-film transistor and organic light-emitting device (OLED) layers from external influences and prevent or reduce the penetration of moisture or oxygen into the OLED layers. Additionally, the layers formed on the array can include inorganic light-emitting layers such as nanoscale material layers or quantum dots.

[0074] Reference Figures 1 to 8 The display device 100 according to an exemplary embodiment of the present disclosure may include a panel frame 120 and a bending member 200.

[0075] In embodiments of this disclosure, the panel frame 120 may be square in shape, but is not necessarily limited to this. A display panel 110 may be disposed in front of the panel frame 120, and a panel driving unit (not shown) for driving the display panel 110 may be arranged inside the panel frame 120. Here, the display panel 110 may be implemented using a deformable (specifically, switchable) structure that can be between a planar shape and a curved shape.

[0076] The bending member 200 may be arranged on the panel frame 120 and may deform the shape of the panel frame 120. In embodiments of this disclosure, the shape of the panel frame 120 may be deformed between a planar shape and a curved shape, but is not necessarily limited to this.

[0077] To deform the display panel 110 and the panel frame 120, the bending member 200 may include a shaft assembly 300 and a drive unit 400.

[0078] The shaft assembly 300 can be arranged on the panel frame 120. (Refer to...) Figure 3 In embodiments of this disclosure, the shaft assembly 300 can be arranged on the rear side of the panel frame 120 in the X-axis direction. Therefore, when the shaft assembly 300 deforms, the side of the panel frame 120 can deform in the same direction as the deformation of the shaft assembly 300.

[0079] However, this configuration is not limited to this, and in other embodiments, it can be arranged on the front side of the panel frame 120 or on the rear side of the panel frame 120 in the Z-axis direction.

[0080] The drive unit 400 can be placed on the panel frame 120 and can deform the shaft assembly 300. (See reference...) Figure 8 The bracket 130 can be connected to the lower part of the panel frame 120 to anchor the panel frame 120 to the ground or a specific location. In this case, the drive unit 400 can be mounted on the bracket 130 to allow simple user operation to switch the display panel 110 and the panel frame 120 between planar and curved shapes.

[0081] Reference Figure 3 and Figure 5 The shaft assembly 300 may include a flexible shaft 310, a support member 390, and a guide member 320.

[0082] The flexible shaft 310 can be disposed on the rear side of the panel frame 120 and is deformable in shape. In embodiments of this disclosure, the flexible shaft 310 can deform between a straight shape and a curved shape. In embodiments of this disclosure, the flexible shaft 310 can have a structure similar to that of a metal cable in which multiple wires 340 are twisted together, but is not necessarily limited to this, and can also be made of other materials that can maintain durability even with frequent deformation.

[0083] The support member 390 can be connected to the rear of the panel frame 120 and can support one end of the flexible shaft 310. Here, the support member 390 can be located at the center of the rear side of the panel frame 120, and the flexible shaft 310 can be arranged in pairs on the rear side of the panel frame 120 along the X-axis with reference to the support member 390.

[0084] In embodiments of this disclosure, the support member 390 may include a fixing plate 391 and a fixing block 392.

[0085] The fixing plate 391 may be flat and have fastening holes 391b formed therein for connection to the rear of the panel frame 120 by fastening bolts (not shown).

[0086] Additionally, refer to Figure 7 The wire groove 391a can be formed on the fixed plate 391 in the X-axis direction (e.g., the arrangement direction of the flexible shaft 310), and the wire 340 can be inserted and arranged in the wire groove 391a. The wire 340 can be guided and moved along the wire groove 391a in the X-axis direction.

[0087] The fixing block 392 can be arranged on the fixing plate 391 and connected to the end of the flexible shaft 310.

[0088] In embodiments of this disclosure, the fixing plate 391 may have a square plate shape and the fixing block 392 may have a square block shape, but they are not limited thereto.

[0089] Furthermore, the guide member 320 can be arranged on the rear side of the panel frame 120 and can guide the deformation of the flexible shaft 310. For example, when the flexible shaft 310 deforms from a straight shape to a curved shape, the guide member 320 can also be deformed from a straight arrangement to a curved arrangement to support and guide the deformation of the flexible shaft 310.

[0090] Reference Figure 3 , Figure 6 and Figure 13 In embodiments of this disclosure, the guide member 320 may include a guide block 330, a wire 340, a flexible beam 350, an end block 360, and a guide rail 370.

[0091] Multiple guide blocks 330 can be arranged on the rear side of the panel frame 120, and multiple guide blocks 330 can be arranged parallel to the X-axis direction on the rear side of the panel frame 120.

[0092] Here, a shaft hole 337 can be formed on the guide block 330, and the flexible shaft 310 can be arranged through the shaft hole 337. For example, the flexible shaft 310 can pass through multiple guide blocks 330 and be arranged parallel to each other.

[0093] The guide block 330 may include a central block 331, a first side block 333, and a second side block 335.

[0094] The central block 331 may have a square block shape, and the shaft hole 337 may be formed in the central block 331. For example, the flexible shaft 310 may be arranged to pass through multiple central blocks 331.

[0095] The first side block 333 can be arranged to face the panel frame 120 from the central block 331, and can extend in two directions from the central block 331.

[0096] The second side block 335 can be arranged from the central block 331 in the opposite direction to the first side block 333, and can extend in both directions of the central block 331.

[0097] Here, when the flexible shaft 310 is linear, the ends of adjacent first side blocks 333 of the plurality of guide blocks 330 can be arranged to be spaced apart by a predetermined distance. Figure 13 (H in the text).

[0098] When the flexible shaft 310 deforms from a straight shape to a curved shape, the ends of adjacent first side blocks 333 can contact each other to limit the curvature range of the flexible shaft 310.

[0099] When the flexible shaft 310 deforms in the Y-axis direction, a predetermined distance (H) ensures that there is space for movement between adjacent first side blocks 333. Additionally, the predetermined distance (H) allows the ends of the first side blocks 333 to contact each other, thereby limiting the curvature range of the flexible shaft 310. Here, the predetermined distance (H) can be determined as a design specification taking into account the curvature, visibility, and prevention of excessive deformation of the display panel 110.

[0100] When the flexible shaft 310 is in a straight line shape, the ends of adjacent second side blocks 335 of the plurality of guide blocks 330 can contact each other to maintain the planar shape of the display panel and the panel frame 120.

[0101] Reference Figure 13 As can be seen, the ends of adjacent second side blocks 335 are in contact with each other, preventing or reducing excessive movement of the flexible shaft 310 in the -Y direction.

[0102] For example, when a user operates the drive unit 400 to change the panel frame 120 from a curved shape to a flat shape, the flexible shaft 310 may move excessively in the -Y direction due to a problem with the gear unit 420 utilizing the drive unit 400. In this case, since the ends of adjacent second side blocks 335 in the flat shape of the panel frame 120 are arranged to contact each other, the excessive movement of the flexible shaft 310 in the -Y direction is limited, and the panel frame 120 can maintain its flat shape even in the event of a failure of the drive unit 400.

[0103] In addition, refer to Figure 13 The wire hole 339 can be formed to pass through both sides of the first side block 333. The wire 340 can be inserted into the wire hole 339 to connect multiple guide blocks 330. For example, the wire 340 can be arranged to pass through and connect multiple first side blocks 333, such that multiple guide blocks 330 are connected via the wire 340.

[0104] The beam support ring 351 may be formed on the second side block 335. The beam support ring 351 may have a ring shape that allows passage (see...). Figure 11 Furthermore, the flexible beam 350 can be arranged to pass through the beam support ring 351. The beam support ring 351 can prevent or reduce the detachment of the flexible beam 350, which is bent into a curved shape, from the guide block 330.

[0105] like Figure 13 As shown, the flexible beam 350 passes through multiple beam support rings 351 and connects to multiple guide blocks 330.

[0106] According to the above structure, the wire 340 is connected to a plurality of guide blocks 330 located on one side of the panel frame 120, while the flexible beam 350 is connected to a plurality of guide blocks 330 located on the opposite side away from the panel frame 120.

[0107] also, Figure 14 This is a diagram illustrating a first recess 333b and a second recess 335b, as well as a first protrusion 333a and a second protrusion 335a, according to an exemplary embodiment of the present disclosure.

[0108] Reference Figure 14 The guide block 330 may also include a first protrusion 333a and a second protrusion 335a, a first recess 333b and a second recess 335b, and a damper member 380.

Figure 10A This is a diagram illustrating the position of the handle 410 on the bracket 130 when the display panel 110 forms a curved screen according to an exemplary embodiment of the present disclosure, and Figure 10B This illustrates an exemplary embodiment of the present disclosure where the handle 410 is as follows: Figure 10A The diagram shows the position of the gear unit 420 when it is located on the bracket 130.

[0128] also, Figure 11 It is along Figure 3 An example of a cross-sectional view of line EE in the diagram, and Figure 12 It is along Figure 3 An example of a cross-sectional view taken from line FF in the image.

[0129] Reference Figure 8 , Figure 11 and Figure 12 The drive unit 400 can be arranged on the panel frame 120 and can deform the shaft assembly 300. In embodiments of this disclosure, the drive unit 400 can transform the panel frame 120 from a planar shape to a curved shape.

[0130] In embodiments of this disclosure, the drive unit 400 may include a gear unit 420 and a lever 410.

[0131] The gear unit 420 may be arranged on the rear of the panel frame 120 and connected to the shaft assembly 300, and may include a shank gear 421, a first gear 422, a linear gear 425, and a second gear 424. The shank 410 may be connected to the gear unit 420 via a shank shaft 411.

[0132] As described above, the panel frame 120 can be supported by the bracket 130, and the drive unit 400 can be arranged inside the bracket 130.

[0133] For example, refer to Figure 9A and Figure 10A One end of the bracket 130 can be placed on a supporting surface such as a wall, floor, or table. The other end of the bracket 130 can be connected to the panel frame 120 to support the surface panel frame 120.

[0134] Here, the bracket 130 may have a first handle groove 413 and a second handle groove 415. The first handle groove 413 may be formed in a recessed shape in the bracket 130 to serve as a receiving portion for the handle 410. In this receiving portion, the position of the handle 410 can ensure that the flexible shaft 310 becomes straight.

[0135] Additionally, a second handle groove 415 can be recessed into the bracket 130 at a certain distance from the first handle groove 413 to serve as a receiving portion for the handle 410. Within this receiving portion, the position of the handle 410 ensures that the flexible shaft 310 can bend.

[0136] However, it is clear that, depending on the design specifications, the positions of the first handle slot 413 and the second handle slot 415 can be reversed or repositioned to different positions on the bracket 130.

[0137] To make the display panel 110 and panel frame 120 planar, the handle 410 is rotated and inserted into the first handle slot 413. Conversely, to make the display panel 110 and panel frame 120 curved, the handle 410 is rotated and inserted into the second handle slot 415. The user can easily switch between planar and curved shapes of the display panel 110 and panel frame 120 by simply rotating the handle 410.

[0138] Reference Figure 9B and Figure 10B The handle 410 and the handle gear 421 can be connected via the handle shaft 411.

[0139] Here, the shank gear may have teeth 421a formed only on a predetermined angular range on the circumferential surface to ensure that when the shank 410 rotates, the first gear 422 rotates only within a specific angular range, rather than rotating on the entire circumferential surface of the shank gear 421.

[0140] Figure 9B The handle 410 is shown in the position where it is inserted into the first handle slot 413, while Figure 10B The handle 410 is shown in the position where it is inserted into the second handle slot 415.

[0141] When the user rotates the handle 410, the handle gear 421, connected to the handle 410 via the handle shaft 411, rotates by the same amount as the handle 410. As the handle gear 421 rotates, its teeth 421a mesh briefly with the teeth 422a of the first gear 422, causing the first gear 422 to rotate. Once the rotation of the handle 410 is complete, the teeth 421a of the handle gear 421 and the teeth 422a of the first gear 422 no longer mesh.

[0142] The first gear 422 can also be connected to the second gear 424 via a gear shaft 423 arranged in the Z-axis direction.

[0143] Figure 12 The arrangement of the second gear 424, the linear gear 425, and the connecting rod 426 is shown.

[0144] The linear gear 425 can be arranged along the length of the flexible beam 350, and the teeth 425a of the linear gear 425 can mesh with the teeth 424a of the second gear 424.

[0145] Link 426 can connect the second gear 424 and wire 340. (See reference) Figure 11 The teeth 424a of the second gear 424 can be arranged in pairs at a predetermined distance in the Z-axis direction, and the connecting rod 426 can be placed between a pair of teeth 424a.

[0146] Therefore, refer to Figure 12 When the second gear 424 rotates in the direction of arrow K1, the connecting rod 426 moves in the direction of rotation of the second gear 424, so that the wire 340 is pulled in the direction of arrow K2.

[0147] When the second gear 424 rotates in the direction of arrow K1, it pushes the linear gear 425 in the direction of arrow K3.

[0148] For example, as the second gear 424 rotates in the direction of arrow K1, it pulls the wire 340 in the direction of arrow K2 and pushes the flexible beam 350 in the direction of arrow K3, causing the wire 340 and the flexible beam 350 to move in opposite directions.

[0149] Furthermore, in embodiments of this disclosure, the flexible shafts are arranged in pairs on both sides of the panel frame 120 relative to the fixing plate 391. On the fixing plate 391, there are a pair of fixing blocks 392 arranged at a certain distance from each other to support one end of each of the paired flexible shafts 310.

[0150] In addition, a pair of second gears 424 are arranged between a pair of fixed blocks 392, and the pair of second gears 424 are respectively connected to a pair of first gears 422 via gear shafts 423. The pair of first gears 422 mesh with a single shank gear 421 and are arranged accordingly.

[0151] According to this structure, the two sides of the display panel 110 and the panel frame 120 are bent in the Y-axis direction relative to the fixing plate 391, and from... Figure 15A The planar shape shown is transformed into, for example, Figure 15B The surface shape shown.

[0152] The display device 100 according to the exemplary embodiment of the present disclosure is constructed as described above, and its operation method will be described below.

[0153] When a user wants to switch the display panel 110 from a flat screen to a curved screen to watch videos or images, they can grasp and rotate it as follows: Figure 9A The handle 410 on the bracket 130 shown.

[0154] Reference Figure 9B When the user grips and rotates the handle 410, the handle 410 and the handle gear 421 rotate because the handle 410 and the handle gear 421 are connected via the handle shaft 411.

[0155] The user can remove the handle 410 from the first handle slot 413 and rotate the handle 410 to insert it into the second handle slot 415, such as Figure 10A As shown. In this case, the rotation of the shank gear 421 is the same as the rotation of the shank 410, causing the first gear 422 meshing with the shank gear 421 to rotate, as shown. Figure 10B As shown.

[0156] Reference Figure 12 The first gear 422 and the second gear 424 are connected by a gear shaft 423, such that the second gear 424 rotates by the same amount as the first gear 422.

[0157] When the display panel 110 and panel frame 120 are switched from a planar shape to a curved shape, the second gear 424 can rotate in the direction of arrow K1.

[0158] As the second gear 424 rotates in the direction of arrow K1, the linear gear 425 meshing with the second gear 424 moves in the direction of arrow K3. As a result, the flexible beam 350 is pushed by a force in the direction of arrow K3.

[0159] Furthermore, the wire 340, which is connected to the second gear 424 via the connecting rod 426, moves in the direction of arrow K2. The wire 340 is pulled in the direction of arrow K2.

[0160] Figure 15A and Figure 15B The general arrangement of the flexible shaft 310 and guide block 330 based on the state of the wire 340 and flexible beam 350 is shown. Although Figure 15A and Figure 15B Not shown in the diagram, but wire 340 and flexible beam 350 are as follows: Figure 3 and Figure 13 The layout is shown.

[0161] Reference Figure 15AThe display panel 110 and panel frame 120 are depicted in their initial planar state. In this case, since the wire 340 and flexible beam 350 are not subjected to any force, the flexible shaft 310 maintains a straight shape.

[0162] Reference Figure 12 and Figure 15B As the second gear 424 rotates in the direction of arrow K1, it pulls the wire 340 in the direction of arrow K2 and pushes the flexible beam 350 in the direction of arrow K3, causing the flexible shaft 310 to deform into a curved shape.

[0163] As a result, the multiple guide blocks 330 connected along the longitudinal direction of the flexible shaft 310 are arranged in the curved shape of the flexible shaft 310.

[0164] This causes the multiple guide blocks 330 to form a curved shape, which causes the display panel 110 and panel frame 120 to bend in the direction of the arrow, changing from a planar shape to a curved shape.

[0165] Here, the flexible shaft 310 can form a surface with gradually increasing curvature until the ends of adjacent first side blocks 333 among the plurality of guide blocks 330 contact each other. The surface has maximum curvature when the ends of adjacent first side blocks 333 among the plurality of guide blocks 330 contact each other.

[0166] This means that the flexible shaft 310 no longer deforms when the ends of adjacent first side blocks 333 come into contact. The distance H between adjacent first side blocks 333 can be determined based on design specifications such as the curvature of the display panel 110, visibility, and prevention or reduction of excessive deformation.

[0167] For example, distance H can be determined as follows: Figure 16A and Figure 16B The design specifications are shown.

[0168] Figure 16A This is a graph illustrating the corresponding position values ​​in the X and Y directions under the target curvature of a display device according to an exemplary embodiment of the present disclosure, and Figure 16B This is a graph illustrating the relationship between target curvature (x) and distance (y; H) in a display device according to an exemplary embodiment of the present disclosure.

[0169] Figure 16A and Figure 16B The information provided is only one example of a design specification for deriving the distance H required to achieve the target curvature, and other design specifications may be applied.

[0170] Reference Figure 16AIt shows the Y-axis position value (Y-axis position (mm) corresponding to the X-axis position value (X position; mm) in the surface display panel (110) and panel frame (120) under the target curvature.

[0171] Figure 16A The Y-axis position value (Y-position; mm) corresponding to the X-axis position value (X-position; mm) is shown based on the target curvature of the curved display panel 110 and panel frame 120.

[0172] This means that when transitioning from a flat screen to a curved screen, the side edges of the display panel 110 and the panel frame 120 can be bent by approximately 140 mm relative to their center in the Y-axis direction.

[0173] Figure 16B The graph presented shows the distance value (y) associated with the target curvature value x; Figure 13 (H in the equation). This relationship can be derived using the following functional formula.

[0174] y = 0.065x 2 -0.6402x+1.6395

[0175] (x = target curvature, y = distance (H))

[0176] When the target curvature x is set to the value in Table 1, the distance (y; H) can be obtained by the above formula and derived as follows.

[0177] Table 1

[0178] 600R 1.0682 800R 0.6072 1000R 0.3156 1200R 0.1146

[0179] Referring to Table 1, when the target curvature is set to 800R, the distance H between the first side blocks 333 can be designed to be 0.6072mm.

[0180] For example, when the distance value H is designed to be 0.6072 mm, when the user switches the display device from a flat screen to a curved screen, the side edges of the display panel 110 and the panel frame 120 will bend by approximately 140 mm in the Y-axis direction, forming a curved screen. As can be seen from Table 1, the distance H becomes larger as the target curvature increases (e.g., from 1200R to 600R).

[0181] The above design specifications are merely examples, and the distance value H can be determined using other design specifications.

[0182] According to an exemplary embodiment of this disclosure, based on the above-described construction and operation method, the display device 100 can switch between a flat screen and a curved screen through a simple and easy operation by the user gripping and rotating the handle 410.

[0183] When switching to a curved screen, a predetermined curvature can be formed on the screen through a smooth transition, so as to accurately achieve the desired curvature shape.

[0184] It should be noted that although the above exemplary embodiments of this disclosure describe the display device 100 switching between a flat screen and a curved screen, this disclosure is not limited thereto. For example, the display device 100 can switch between a flat screen and two or more curved screens by rotating the lever 410 by different degrees. In this case, there are three or more lever slots in the bracket 130 to fix the lever 410 in different positions. In another example, the display device 100 can be arbitrarily switched to adjust the full degree according to the user's operation of the lever 410.
