[0059] The display panel (10) may include edges. The display panel (10) may include a first edge (EG1) and a second edge (EG2). The first edge (EG1) and the second edge (EG2) may each be ends of the display panel (10). In one embodiment, the first edge (EG1) and the second edge (EG2) may meet each other. In this case, the first edge (EG1) and the second edge (EG2) may intersect each other. Alternatively, the first edge (EG1) and the second edge (EG2) may meet each other in a curved shape.

[0060] The first edge (EG1) may be extended in the first direction. The second edge (EG2) may be extended in the second direction. In this case, the first direction and the second direction may intersect each other. For example, the first direction and the second direction may form an acute angle, a right angle, or an obtuse angle with each other. Below, we will explain in detail focusing on the case where the first direction is the x direction or the -x direction and the second direction is the y direction or the -y direction.

[0069] In one embodiment, the component area (CPA) may be provided in multiple numbers. In one embodiment, the multiple component areas (CPA) may be spaced apart from each other in a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction).

[0070] The component area (CPA) may be positioned offset from the center of the display panel (10) in a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction) of the display panel (10).

[0078] The frame assembly (20) can bend the display panel (10) from a first direction (e.g., x direction or -x direction) into a third direction (e.g., z direction or -z direction) that intersects the first direction (e.g., x direction or -x direction) and the second direction (e.g., y direction or -y direction). In this specification, the meaning of bending a component from a first direction (e.g., x direction or -x direction) into a third direction (e.g., z direction or -z direction) is that the cross section of the component that intersects a plane (e.g., xz plane) extending in the first direction (e.g., x direction or -z direction) and the third direction (e.g., z direction or -z direction) is bent concavely or convexly.

[0079] The first edge (EG1) of the bent display panel (10) may have curvature. The first edge (EG1) of the bent display panel (10) may be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction).

[0080] The frame assembly (20) can bend the display panel (10) from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction). In this specification, bending a component from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction) means that the cross section of the component intersects a plane (e.g., yz plane) extending in the second direction (e.g., y direction or -y direction) and the third direction (e.g., z direction or -z direction) is bent concavely or convexly.

[0081] The second edge (EG2) of the bent display panel (10) may have curvature. The second edge (EG2) of the bent display panel (10) may be bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction).

[0082] The frame assembly (20) can bend the display panel (10) from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction) and bend the display panel (10) from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction). Accordingly, the first edge (EG1) and the second edge (EG2) of the bent display panel (10) may each have a curvature.

[0083] The frame assembly (20) can be controlled by a controller (1700). The frame assembly (20) can be controlled by the controller (1700) to bend from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). The frame assembly (20) can be controlled by the controller (1700) to bend from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction). The frame assembly (20) may include a frame set (21) and a plurality of supporters (27).

[0084] A frame set (21) can bend a display panel (10). The frame set (21) may include a frame and a wire (21WR). The frame set (21) may be positioned at the rear of the display panel (10). The frame set (21) can bend the display panel (10) at the rear of the display panel (10). In one embodiment, the frame set (21) may be provided in multiple numbers. In other words, the frame set (21) may include multiple frame sets (21).

[0085] A plurality of frame sets (21) may include a first frame set (23) and a second frame set (25). In other words, a frame set (21) may include a first frame set (23) and a second frame set (25).

[0086] In one embodiment, a second frame set (25) may be placed between the first frame set (23) and the display panel (10). In one embodiment, the first frame set (23) and the second frame set (25) may bend the display panel (10) such that the first edge (EG1) and the second edge (EG2) each have a curvature.

[0087] The first frame set (23) may be extended in a first direction (e.g., x direction or -x direction). FIG. 3a illustrates a single first frame set (23) positioned at the rear of the display panel (10), but in other embodiments, the first frame set (23) may be provided in multiple units at the rear of the display panel (10).

[0088] The first frame set (23) can be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). The first frame set (23) can be bent by being controlled by a controller (1700). Thus, the first frame set (23) can bend the display panel (10) from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). Additionally, the first frame set (23) can bend the display panel (10) so that the first edge (EG1) of the display panel (10) has curvature.

[0089] The second frame set (25) may be extended in a second direction (e.g., the y direction or the -y direction). The second frame set (25) may be positioned at the rear of the display panel (10). In one embodiment, the second frame set (25) may be provided in multiple numbers at the rear of the display panel (10). In another embodiment, one second frame set (25) may be positioned at the rear of the display panel (10).

[0090] The second frame set (25) can be bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction). The second frame set (25) can be bent by being controlled by a controller (1700). Thus, the second frame set (25) can bend the display panel (10) from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction). Additionally, the second frame set (25) can be bent so that the second edge (EG2) of the display panel (10) has curvature.

[0091] In one embodiment, the first frame set (23) and the second frame set (25) may intersect each other. In this case, the first frame set (23) and the second frame set (25) may be fixed to each other at the point where the first frame set (23) and the second frame set (25) intersect each other.

[0092] The wire (21WR) can bend the frame set (21). In other words, the wire (21WR) can bend the frame included in the frame set (21). In one embodiment, the controller (1700) can adjust the length of the wire (21WR). When the length of the wire (21WR) is reduced, the frame set (21) can be bent. For example, if the wire (21WR) is retracted or the length of the wire (21WR) is shortened by a motor, the frame set (21) can be bent.

[0093] In one embodiment, the wire (21WR) may include a first wire (21WR1), a second wire (21WR2), a third wire (21WR3), and a fourth wire (21WR4). In one embodiment, the length of the first wire (21WR1), the length of the second wire (21WR2), the length of the third wire (21WR3), and the length of the fourth wire (21WR4) may be adjusted independently.

[0094] The first wire (21WR1) and the second wire (21WR2) can bend the frame included in the first frame set (23). In one embodiment, the length of the first wire (21WR1) and the length of the second wire (21WR2) can be adjusted independently. In this case, the degree of bending of the first frame set (23) extended in the -x direction and the degree of bending of the first frame set (23) extended in the x direction may be different. In one embodiment, the third wire (21WR3) and the fourth wire (21WR4) can bend the frame included in the second frame set (25). In one embodiment, the length of the third wire (21WR3) and the length of the fourth wire (21WR4) can be adjusted independently. In this case, the degree of bending of the second frame set (25) extended in the y direction and the degree of bending of the second frame set (25) extended in the -y direction may be different.

[0095] A plurality of supporters (27) can support the display panel (10). A plurality of supporters (27) can be positioned between the display panel (10) and the frame set (21). A plurality of supporters (27) can be fixed to the frame set (21). In one embodiment, a plurality of supporters (27) can be positioned between the display panel (10) and the first frame set (23). In one embodiment, a plurality of supporters (27) can be positioned between the display panel (10) and the second frame set (25).

[0096] A plurality of supporters (27) can maintain the shape of the display panel (10). In one embodiment, the display panel (10) may be a stretchable display panel. In this case, the shape of the display panel (10) can be varied. Since the plurality of supporters (27) support the display panel (10), the shape of the display panel (10) can be maintained.

[0097] In one embodiment, a plurality of supporters (27) may be arranged side by side in a second direction (e.g., the y direction or the -y direction). For example, a plurality of supporters (27) may be spaced apart from each other along the second direction (e.g., the y direction or the -y direction). In another embodiment, a plurality of supporters (27) may be arranged side by side in a first direction (e.g., the x direction or the -x direction). For example, a plurality of supporters (27) may be spaced apart from each other along the first direction (e.g., the x direction or the -x direction). Below, the case in which a plurality of supporters (27) are arranged side by side in a second direction (e.g., the y direction or the -y direction) will be described in detail.

[0098] In one embodiment, the supporter (27) may comprise austenitic stainless steels. In another embodiment, the supporter (27) may be made of stainless steel, invar, nickel (Ni), cobalt (Co), nickel alloy, nickel-cobalt alloy, etc. In yet another embodiment, the supporter (27) may be made of various metal materials. In yet another embodiment, the supporter (27) may comprise a polymer compound, for example, a polymer.

[0099] A plurality of supporters (27) can be bent. In one embodiment, a first frame set (23) can bend a plurality of supporters (27). A plurality of supporters (27) can be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). In one embodiment, a first frame set (23) can bend a plurality of supporters (27) from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). For example, when the first frame set (23) is bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction), a plurality of supporters (27) can also be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). Accordingly, the display panel (10) can be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction).

[0100] At least one of the plurality of supporters (27) can move in a third direction (e.g., z direction or -z direction). For example, among the plurality of supporters (27), the supporter (27) positioned adjacent to the first edge (EG1) can move in a third direction (e.g., z direction or -z direction). In one embodiment, the second frame set (25) can move at least one of the plurality of supporters (27) in a third direction (e.g., z direction or -z direction). For example, when the second frame set (25) is bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction), at least one of the plurality of supporters (27) can move in a third direction (e.g., z direction or -z direction). Accordingly, the display panel (10) can be bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction).

[0101] The controller (1700) acquires information to bend the display panel (10) and can bend the display panel (10) by taking into account the acquired information. The controller (1700) may include a first driving unit (1710) and a second driving unit (1730).

[0102] The first driving unit (1710) can control the frame assembly (20). In one embodiment, the first driving unit (1710) can control the bending of the frame set (21). In one embodiment, the first driving unit (1710) may include a motor. The motor can contract the wire (21WR) or wind the wire (21WR) to reduce the length of the wire (21WR).

[0103] In one embodiment, the first driving unit (1710) may include a plurality of motors. Each of the plurality of motors can control the bending of the first frame set (23) and the second frame set (25). In one embodiment, the plurality of motors can control the bending of a single frame set (21). For example, when the plurality of motors control the first frame set (23), the bending of both ends of the first frame set (23) can be controlled independently. The plurality of motors can each control the length of the first wire (21WR1) and the length of the second wire (21WR2). As another example, when the plurality of motors control the second frame set (25), the bending of both ends of the second frame set (25) can be controlled independently. The plurality of motors can each control the length of the third wire (21WR3) and the fourth wire (21WR4). Accordingly, the display panel (10) can be bent into various shapes.

[0104] In one embodiment, the first driving unit (1710) may be positioned at the rear of the display unit (1100). In this case, the first driving unit (1710) may include a fixing member that fixes the display unit (1100) to an external wall or the like. For example, the fixing member may include a bracket.

[0105] The second driving unit (1730) can control the display unit (1100) to rotate around a second direction (e.g., y direction or -y direction) as an axis. In one embodiment, the second driving unit (1730) may include a motor. The motor can rotate the display unit (1100) around a second direction (e.g., y direction or -y direction) as an axis. Thus, the display panel (10) can be rotated around a second direction (e.g., y direction or -y direction) as an axis by the controller (1700).

[0106] FIGS. 3B, FIGS. 3C, and FIGS. 3D are perspective views schematically illustrating a display device (1) according to various embodiments of the present invention. FIGS. 3B, FIGS. 3C, and FIGS. 3D are perspective views showing the rear side of a display unit (1100). In FIGS. 3B, FIGS. 3C, and FIGS. 3D, reference numerals identical to those in FIG. 3A denote identical components, so redundant descriptions are omitted.

[0107] Referring to FIGS. 3b, 3c, and 3d, the display device (1) may include a display unit (1100) and a controller (1700). The display unit (1100) may include a display panel (10) and a frame assembly (20). The frame assembly (20) may include a frame set (21) and a plurality of supporters (27). In one embodiment, the frame set (21) may include a plurality of frame sets (21).

[0108] Referring to FIG. 3b, a plurality of frame sets (21) may include a first frame set (23) and a second frame set (25). In one embodiment, the first frame set (23) and the second frame set (25) may be provided integrally.

[0109] Referring to FIG. 3c, a plurality of frame sets (21) may include a first frame set (23) and a second frame set (25). In one embodiment, the second frame set (25) may include a center frame set (25A), an edge frame set (25B), and an intermediate frame set (25C). In one embodiment, the center frame set (25A) may overlap with the center of the display panel (10). The edge frame set (25B) may be adjacent to the second edge (EG2). The intermediate frame set (25C) may be positioned between the center frame set (25A) and the edge frame set (25B). FIG. 3c illustrates that there is only one intermediate frame set (25C), but in other embodiments, the intermediate frame set (25C) may be provided in multiple numbers.

[0110] In one embodiment, the first distance (dis1) between the center frame set (25A) and the middle frame set (25C) may be greater than the second distance (dis2) between the middle frame set (25C) and the edge frame set (25B). The first distance (dis1) may be the distance between the center frame set (25A) and the middle frame set (25C) in a first direction (e.g., the x direction or the -x direction). The second distance (dis2) may be the distance between the middle frame set (25C) and the edge frame set (25B) in a first direction (e.g., the x direction or the -x direction). In this case, the bending force applied to the corners of the display panel (10) may be increased.

[0111] Referring to FIG. 3d, a plurality of frame sets (21) may include a first frame set (23), a second frame set (25), and a third frame set (26). The third frame set (26) may extend in a direction intersecting the first direction (e.g., x direction or -x direction) and the second direction (e.g., y direction or -y direction). In one embodiment, the third frame set (26) may extend from the center of the display panel (10) toward the corner of the display panel (10). In one embodiment, the third frame set (26) may be provided in multiple numbers. The third frame set (26) may bend the display panel (10) such that the first edge (EG1) and the second edge (EG2) each have curvature. In this case, at least one of the first frame set (23) and the second frame set (25) may be omitted.

[0112] FIG. 4 is an exploded view of part A of the display portion (1100) of FIG. 3a. In FIG. 4, the same reference numerals as in FIG. 3a denote the same components, so redundant descriptions will be omitted.

[0113] Referring to FIG. 4, the display unit (1100) may include a display panel (10) and a frame set (21). The display panel (10) may display an image. The frame set (21) is positioned behind the display panel (10) and may bend the display panel (10). The frame set (21) may include a frame (21F), a wire (21WR), and an intermediate frame (21MF). The frame set (21) may be the first frame set (23) of FIG. 3a and / or the second frame set (25) of FIG. 3a.

[0114] The frame (21F) can be bent, and the frame (21F) can bend the display panel (10). The frame (21F) may have a body (21B), a head (21H), and a protruding pattern (21P). The body (21B) may be extended in the longitudinal direction. For example, the body (21B) may be extended along a second direction (e.g., the y direction or the -y direction). As another example, the body (21B) may be extended along a first direction (e.g., the x direction or the -x direction). The body (21B) may have a fixed point. The fixed point may be a point where a part of the body (21B) is relatively fixed with respect to the head (21H). The head (21H) may protrude in a direction intersecting the longitudinal direction of the body (21B). In one embodiment, the head (21H) may protrude from the body (21B) toward the rear of the display panel (10). For example, the head (21H) may protrude in the z-direction in FIG. 4.

[0115] The protruding pattern (21P) may protrude in a direction intersecting the longitudinal direction of the body (21B). In one embodiment, the protruding pattern (21P) may protrude toward the rear of the display panel (10). For example, the protruding pattern (21P) may protrude in the z direction of FIG. 4. The protruding pattern (21P) may be spaced apart from the head (21H) along the longitudinal direction of the frame (21F). For example, the protruding pattern (21P) may be spaced apart from the head (21H) along the y direction of FIG. 4.

[0116] The protruding pattern (21P) may have a through hole (21PH). The through hole (21PH) may penetrate the protruding pattern (21P) in the longitudinal direction of the frame (21F). For example, in FIG. 4, the through hole (21PH) may penetrate the protruding pattern (21P) in the y-direction. In this case, the wire (21WR) may extend through the through hole (21PH). In one embodiment, the frame (21F) may have one protruding pattern (21P). In another embodiment, the frame (21F) may have a plurality of protruding patterns (21P).

[0117] The frame (21F) may comprise austenitic stainless steels. In another embodiment, the frame (21F) may be made of stainless steel, invar, nickel (Ni), cobalt (Co), nickel alloy, nickel-cobalt alloy, etc. In yet another embodiment, the frame (21F) may be made of various metal materials. In yet another embodiment, the frame (21F) may comprise a polymer compound, for example, a polymer.

[0118] The wire (21WR) may extend along the longitudinal direction of the frame (21F). The wire (21WR) may be fixed to the head (21H). In one embodiment, the end of the wire (21WR) may be fixed to the head (21H). Thus, if the length of the wire (21WR) is reduced, the frame (21F) may be bent. That is, the wire (21WR) may apply a torsional moment to the frame (21F), and due to this torsional moment, the frame (21F) may be bent.

[0119] The wire (21WR) can be positioned between the display panel (10) and the body (21B). The wire (21WR) can be extended between the display panel (10) and the body (21B) and secured to the head (21H). Thus, the wire (21WR) can apply a torsional moment to the frame (21F).

[0120] The wire (21WR) can pass through the through hole (21PH). In one embodiment, the wire (21WR) can pass through one through hole (21PH). In another embodiment, the wire (21WR) can pass through a plurality of through holes (21PH). In this embodiment, the protruding pattern (21P) having the through hole (21PH) through which the wire (21WR) passes can be spaced apart from the head (21H). Accordingly, the protruding pattern (21P) can control the torsional moment acting on the frame (21F) when the length of the wire (21WR) decreases, and can control the shape of the frame (21F) being bent.

[0121] An intermediate frame (21MF) may be positioned between the display panel (10) and the frame (21F). In one embodiment, the intermediate frame (21MF) may be positioned between a plurality of supporters (27) and the frame (21F). In one embodiment, the intermediate frame (21MF) may be fixed to a plurality of supporters (27). The intermediate frame (21MF) may extend along the longitudinal direction of the frame (21F). For example, the intermediate frame (21MF) may extend along the y direction of FIG. 4. In one embodiment, the intermediate frame (21MF) and the frame (21F) may extend side by side. The intermediate frame (21MF) and the frame (21F) may face each other. The frame (21F) may be provided with a head (21H) and / or a protruding pattern (21P), and when the frame (21F) is bent, strain may be concentrated on the display panel (10) and / or a plurality of supporters (27) that overlap with the head (21H) and / or the protruding pattern (21P). In this embodiment, the intermediate frame (21MF) may prevent or reduce strain concentration by the frame (21F) on at least some of the display panel (10) and / or the plurality of supporters (27).

[0122] The intermediate frame (21MF) can move relative to the head (21H). In other words, the head (21H) can move relative to the intermediate frame (21MF). That is, a part of the intermediate frame (21MF) and a part of the frame (21F) may be fixed, and the intermediate frame (21MF) and the head (21H) may not be fixed to each other. In one embodiment, the point where the intermediate frame (21MF) and the head (21H) are fixed to each other may be the point where the first frame set (23, see FIG. 3A) and the second frame set (25, see FIG. 3A) intersect. For example, a part of the intermediate frame (21MF) and a part of the frame (21F) may be welded. As another example, a groove may be provided in a part of the intermediate frame (21MF) and a protrusion may be provided in a part of the frame (21F), and a part of the intermediate frame (21MF) and a part of the frame (21F) may be fixed. As another example, a protrusion may be provided on a part of the intermediate frame (21MF) and a groove may be provided on a part of the frame (21F), and a part of the intermediate frame (21MF) and a part of the frame (21F) may be fixed together.

[0123] If the intermediate frame (21MF) and the head (21H) are fixed to each other, the display panel (10) may be bent beyond a preset value when the frame (21F) is bent. In this case, the display panel (10) may be stretched beyond a preset value, and the display panel (10) may be damaged. In this embodiment, since the intermediate frame (21MF) can move relative to the head (21H), the display panel (10) may be bent below a preset value. Therefore, damage to the display panel (10) can be prevented or reduced.

[0124] The intermediate frame (21MF) may comprise austenitic stainless steels. In another embodiment, the intermediate frame (21MF) may be made of stainless steel, invar, nickel (Ni), cobalt (Co), nickel alloy, nickel-cobalt alloy, etc. In yet another embodiment, the intermediate frame (21MF) may be made of various metal materials. In yet another embodiment, the intermediate frame (21MF) may comprise a polymer compound, for example, a polymer.

[0125] Either the head (21H) or the intermediate frame (21MF) may have a concave portion (21CA) facing the other of the head (21H) and the intermediate frame (21MF). Additionally, the other of the head (21H) and the intermediate frame (21MF) may have a convex portion (21CB) facing the concave portion (21CA). For example, the head (21H) may have a concave portion (21CA), and the intermediate frame (21MF) may have a convex portion (21CB). As another example, the head (21H) may have a convex portion (21CB), and the intermediate frame (21MF) may have a concave portion (21CA). Below, we will describe in detail focusing on the case where the head (21H) has a concave portion (21CA) and the intermediate frame (21MF) has a convex portion (21CB).

[0126] The concave portion (21CA) and the convex portion (21CB) can each extend along the longitudinal direction of the frame (21F). The concave portion (21CA) and the convex portion (21CB) can face each other. The concave portion (21CA) and the convex portion (21CB) can guide the head (21H) and the intermediate frame (21MF) to move relative to each other in one direction. Thus, the concave portion (21CA) and the convex portion (21CB) can increase the reliability of the frame set (21).

[0127] FIGS. 5A, FIGS. 5B, and FIGS. 5C are schematic plan views illustrating a plurality of supporters (27) and a display panel (10) according to various embodiments of the present invention. In FIGS. 5A to 5C, reference numerals identical to those in FIG. 3A denote identical components, so redundant descriptions are omitted.

[0128] Referring to FIGS. 5a through 5c, the display panel (10) may include a first edge (EG1) extended in a first direction (e.g., x direction or -x direction) and a second edge (EG2) extended in a second direction (e.g., y direction or -y direction). A plurality of supporters (27) may support the display panel (10). A plurality of supporters (27) may maintain the shape of the display panel (10). In one embodiment, a plurality of supporters (27) may be arranged side by side in a second direction (e.g., y direction or -y direction).

[0129] Referring to FIG. 5a, a plurality of supporters (27) may be extended in a first direction (e.g., x direction or -x direction). A plurality of supporters (27) may be spaced apart from each other along a second direction (e.g., y direction or -y direction).

[0199] A plurality of pixel regions (PAs) may be spaced apart in a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction). In one embodiment, a plurality of pixel regions (PAs) may each be spaced apart by a first interval (d1) and a second interval (d2). For example, a first pixel region (PA1) and a second pixel region (PA2) may be spaced apart in a first direction (e.g., x direction or -x direction) and / or a second direction (e.g., y direction or -y direction).

[0200] A connection area (CA) can be extended between adjacent pixel areas (PA). In one embodiment, each pixel area (PA) can be connected to four connection areas (CA). The four connection areas (CA) connected to one pixel area (PA) extend in different directions, and each connection area (CA) can be connected to another pixel area (PA) that is adjacent to the aforementioned pixel area (PA).

[0201] In one embodiment, the first connection area (CA1) may extend from the first pixel area (PA1) to the second pixel area (PA2). Accordingly, the first pixel area (PA1) and the second pixel area (PA2) may be connected by the first connection area (CA1), and the first pixel area (PA1), the second pixel area (PA2), and the first connection area (CA1) may be provided as a single unit.

[0202] In one embodiment, at least a portion of the penetration portion (TP) may be defined as the edge (PAE1) of the first pixel area (PA1), the edge (PAE2) of the second pixel area (PA2), and the edge (CAE1) of the first connection area (CA1). In one embodiment, at least a portion of the penetration portion (TP) may be defined as the edge (PAE1) of the first pixel area (PA1), the edge (PAE2) of the second pixel area (PA2), the edge (CAE1) of the first connection area (CA1), and the edge (CAE2) of the second connection area (CA2).

[0203] A portion of a pixel area (PA) and the connecting areas (CA) extending therefrom can be defined as a basic unit (U). The basic unit (U) may be repeatedly arranged along a first direction (e.g., x direction or -x direction) and a second direction (e.g., y direction or -y direction), and the display panel (10) can be understood as being provided by connecting the repeatedly arranged basic units (U) to each other. Two basic units (U) adjacent to each other may be symmetrical to each other. For example, in FIG. 10, two basic units (U) adjacent in the left-right direction may be located between them and may be symmetrical with respect to a symmetry axis parallel to the second direction (e.g., y direction or -y direction). Similarly, in FIG. 10, two basic units (U) adjacent in the up-down direction may be located between them and may be symmetrical with respect to a symmetry axis parallel to the first direction (e.g., x direction or -x direction).

[0204] Among a plurality of basic units (U), adjacent basic units (U), for example, the four basic units (U) shown in FIG. 10, form a closed curve (CL) between them, which can define a gap area (V) that is an empty space. The gap area (V) can be defined as a closed curve (CL) composed of the edges of a plurality of pixel areas (PA) and the edges of a plurality of connection areas (CA). Each gap area (V) can penetrate the upper and lower surfaces of the display panel (10). The gap area (V) can overlap with the penetration portion (TP) of the display panel (10).

[0205] In one embodiment, the angle (θ) between the edge (CAE1) of the first connection area (CA1) and the edge (PAE2) of the second pixel area (PA2) may be an acute angle. When a tensile force and / or a contraction force is applied to the display panel (10), the angle (θ) between the edge (CAE1) of the first connection area (CA1) and the edge (PAE2) of the second pixel area (PA2) may be changed.

[0206] The first pixel (PX1) and the second pixel (PX2) may overlap with the first pixel area (PA1) and the second pixel area (PA2), respectively. In one embodiment, the first pixel (PX1) and the second pixel (PX2) may each include a red subpixel, a green subpixel, and a blue subpixel. In another embodiment, the first pixel (PX1) and the second pixel (PX2) may each include a red subpixel, a green subpixel, a blue subpixel, and a white subpixel.

[0207] The structure of the display panel (10) described with reference to FIG. 10 describes the structure of the display panel (10) of the corner display area (CDA), but in other embodiments, the structure of the display panel (10) of the center display area (CTDA) of FIG. 7 may be identical or similar to the structure of the display panel (10) described with reference to FIG. 10.

[0208] FIG. 11 is a schematic cross-sectional view of a display panel (10) along the line E-E' of FIG. 10. In FIG. 11, the same reference numerals as in FIG. 9 denote the same components, so redundant descriptions will be omitted.

[0209] Referring to FIG. 11, the display panel (10) may have a penetration portion (TP). A first pixel area (PA1) and a second pixel area (PA2) may be separated by the penetration portion (TP).

In one embodiment, the pixel circuit layer (PCL) may further include a first inorganic layer (PVX1). In one embodiment, the display element layer (DEL) may further include a second inorganic layer (PVX2).

[0211] Hereinafter, the stacked structure of a display panel (10) having a penetration portion (TP) will be described in detail. However, the stacked structure of a display panel (10) having a penetration portion (TP) is not limited thereto, and various embodiments may be possible.

[0212] The organic insulating layer (OIL) may have a hole (HL). In one embodiment, the hole (HL) may be provided by overlapping the hole in the first organic insulating layer (115) and the hole in the second organic insulating layer (116). In another embodiment, the hole (HL) may be provided in the second organic insulating layer (116). In this case, the upper surface of the first organic insulating layer (115) may be exposed by the hole in the second organic insulating layer (116). Hereinafter, the case in which the hole (HL) is provided in the first organic insulating layer (115) and the second organic insulating layer (116) will be described in detail.

[0213] In some embodiments, the organic insulating layer (OIL) may have a groove formed in the thickness direction of the organic insulating layer (OIL) instead of a hole (HL). In some embodiments, the organic insulating layer (OIL) may not have a hole (HL) or a groove.

[0214] In one embodiment, the first inorganic layer (PVX1) may be disposed between the interlayer insulating layer (114) and the first organic insulating layer (115). The first inorganic layer (PVX1) may cover the first source electrode (SE1), the first drain electrode (DE1), the second source electrode (SE2), and the second drain electrode (DE2). In one embodiment, the first inorganic layer (PVX1) may have a contact hole so that the first source electrode (SE1) or the first drain electrode (DE1) is electrically connected to the connecting electrode (CML).

[0215] In another embodiment, the first inorganic layer (PVX1) may be disposed between the first organic insulating layer (115) and the second organic insulating layer (116). In this case, the first inorganic layer (PVX1) may cover the connecting electrode (CML). At least a portion of the first inorganic layer (PVX1) may be exposed by a hole (HL). The first inorganic layer (PVX1) is silicon nitride (SiN X It may be a single film or a multilayer film comprising an inorganic material such as silicon oxide (SiO2) and / or silicon oxide (SiO2). In some embodiments, the first inorganic layer (PVX1) may be omitted.

[0216] An organic light-emitting diode (OLED) may be disposed on a second organic insulating layer (116). The organic light-emitting diode (OLED) may include a first organic light-emitting diode (OLED1) and a second organic light-emitting diode (OLED2). The first organic light-emitting diode (OLED1) may be disposed on a substrate (100) so as to overlap with a first pixel area (PA1) as a first display element. The first organic light-emitting diode (OLED1) may implement a first pixel (PX1). The second organic light-emitting diode (OLED2) may be disposed on a substrate (100) so as to overlap with a second pixel area (PA2) as a second display element. The second organic light-emitting diode (OLED2) may implement a second pixel (PX2).

[0217] The first organic light-emitting diode (OLED1) may include a first pixel electrode (211A), an intermediate layer (212), and a counter electrode (213). The second organic light-emitting diode (OLED2) may include a second pixel electrode (211B), an intermediate layer (212), and a counter electrode (213). The first pixel electrode (211A) and the second pixel electrode (211B) may each be connected to a connecting electrode (CML) through a contact hole of the second organic insulating layer (116).

[0218] A second inorganic layer (PVX2) may be disposed between the organic light-emitting diode (OLED) and the second organic insulating layer (116). The second inorganic layer (PVX2) may include a plurality of inorganic patterns spaced apart from each other on the second organic insulating layer (116). The second inorganic layer (PVX2) may have a protruding tip (PT) protruding toward the center of the hole (HL). Thus, the lower surface of the protruding tip (PT) may be exposed in the hole (HL). That is, the hole (HL) may have an undercut structure. The second inorganic layer (PVX2) is silicon nitride (SiN X It may be a single film or a multilayer film containing inorganic materials such as silicon oxide (SiO2) and / or silicon oxide (SiO2).

[0219] The protruding tip (PT) of the hole (HL) and the second inorganic layer (PVX2) may be a structure for disconnecting the first functional layer (212a) and the second functional layer (212c). In one embodiment, the first functional layer (212a), the second functional layer (212c), and the counter electrode (213) may be formed on the front surface of the substrate (100). In this case, the first functional layer (212a) and the second functional layer (212c) may contain organic material, and external oxygen or moisture, etc., may be introduced into the organic light-emitting diode (OLED) from the penetration part (TP) through at least one of the first functional layer (212a) and the second functional layer (212c). Such oxygen or moisture may damage the organic light-emitting diode (OLED). The protruding tip (PT) of the hole (HL) and the second inorganic layer (PVX2) can disconnect the first functional layer (212a) and the second functional layer (212c), and the separated first functional layer pattern and second functional layer pattern can be placed inside the hole (HL). Thus, the inflow of moisture or oxygen from the penetration part (TP) into the organic light-emitting diode (OLED) can be prevented, and damage to the organic light-emitting diode (OLED) can be prevented. However, the structure for disconnecting the first functional layer (212a) and the second functional layer (212c) is not limited thereto, and various structures for disconnecting the first functional layer (212a) and the second functional layer (212c) can be applied to the display panel (10).

[0220] The first dam portion (DAM1) and the second dam portion (DAM2) may be disposed on the second inorganic layer (PVX2). The first dam portion (DAM1) and the second dam portion (DAM2) may protrude from the second inorganic layer (PVX2) in the thickness direction of the substrate (100). The first dam portion (DAM1) and the second dam portion (DAM2) may be disposed adjacent to the penetration portion (TP).

[0221] The first dam portion (DAM1) may be placed on the first pixel area (PA1). In one embodiment, the first dam portion (DAM1) may surround the first organic light-emitting diode (OLED1). The first dam portion (DAM1) may be placed closer to the penetration portion (TP) than to the hole (HL). The first dam portion (DAM1) may include a first pattern layer (118D1) and a first upper pattern layer (119D1). In one embodiment, the first pattern layer (118D1) may include the same material as the pixel defining film (118). The first upper pattern layer (119D1) may include an organic insulator and / or an inorganic insulator.

[0222] The second dam portion (DAM2) may be placed on the second pixel area (PA2). In one embodiment, the second dam portion (DAM2) may surround the second organic light-emitting diode (OLED2). The second dam portion (DAM2) may be placed closer to the penetration portion (TP) than to the hole (HL). The second dam portion (DAM2) may include a second pattern layer (118D2) and a second upper pattern layer (119D2). In one embodiment, the second pattern layer (118D2) may include the same material as the pixel defining film (118) and the first pattern layer (118D1). The pixel defining film (118), the first pattern layer (118D1), and the second pattern layer (118D2) may be formed simultaneously. The second upper pattern layer (119D2) may include an organic insulator and / or an inorganic insulator. The second upper pattern layer (119D2) may contain the same material as the first upper pattern layer (119D1). The first upper pattern layer (119D1) and the second upper pattern layer (119D2) may be formed simultaneously. In some embodiments, at least one of the first dam portion (DAM1) and the second dam portion (DAM2) may be omitted.

[0223] The encapsulation layer (ENL) can cover the first organic light-emitting diode (OLED1) and the second organic light-emitting diode (OLED2). The encapsulation layer (ENL) can be placed on the counter electrode (213). The encapsulation layer (ENL) can be separated by a penetration portion (TP). In one embodiment, the encapsulation layer (ENL) may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. In one embodiment, FIG. 11 illustrates that the encapsulation layer (ENL) includes a first inorganic encapsulation layer (310), an organic encapsulation layer (320), and a second inorganic encapsulation layer (330) that are sequentially stacked.

[0224] The first inorganic encapsulation layer (310) can cover an organic light-emitting diode (OLED). The first inorganic encapsulation layer (310) can cover the substrate (100) entirely and continuously. The first inorganic encapsulation layer (310) can cover the first organic light-emitting diode (OLED1), a hole (HL), a first dam portion (DAM1), a second dam portion (DAM2), and a second organic light-emitting diode (OLED2). The first inorganic encapsulation layer (310) can be in contact with the protruding tip (PT) of the second inorganic layer (PVX2). The first inorganic encapsulation layer (310) can be in contact with the first inorganic layer (PVX1). Thus, moisture or oxygen can be prevented from entering the organic light-emitting diode (OLED) through the layer containing organic material from the penetration portion (TP). Additionally, the first weapon sealing layer (310) can be separated based on the penetration portion (TP).

[0225] The organic encapsulation layer (320) may be disposed on the first inorganic encapsulation layer (310). The organic encapsulation layer (320) may overlap with the first organic light-emitting diode (OLED1) and the second organic light-emitting diode (OLED2), and the organic encapsulation layer (320) may fill the hole (HL). In one embodiment, the organic encapsulation layer (320) may be separated based on the penetration portion (TP). For example, the organic encapsulation layer (320) overlapping with the first organic light-emitting diode (OLED1) may extend to the first dam portion (DAM1). The organic encapsulation layer (320) overlapping with the second organic light-emitting diode (OLED2) may extend to the second dam portion (DAM2). The first dam portion (DAM1) and the second dam portion (DAM2) protrude in the thickness direction of the substrate (100) from the upper surface of the second inorganic layer (PVX2), so that the flow of the organic encapsulation layer (320) can be controlled.

[0226] The second inorganic encapsulation layer (330) can cover the organic encapsulation layer (320). The second inorganic encapsulation layer (330) can cover the substrate (100) entirely and continuously. The second inorganic encapsulation layer (330) can be in contact with the first inorganic encapsulation layer (310) on the first dam portion (DAM1) and the second dam portion (DAM2). Thus, the organic encapsulation layer (320) can be separated by the first dam portion (DAM1) and the second dam portion (DAM2). Additionally, the second inorganic encapsulation layer (330) can be separated based on the penetration portion (TP).

[0227] Hereinafter, an example of a control method for a display device that controls a display device (1) to bend a display panel (10) and / or an example of a display device (1) including a bent display panel (10) will be described.

[0228] FIG. 12 is a side view schematically showing the shape of the display panel (10) and frame set (21) before bending.

[0229] Referring to FIG. 12, a display panel (10) can display an image. The display panel (10) may include edges. In one embodiment, the display panel (10) may include a first edge (EG1) extended in a first direction (e.g., x direction or -x direction) and a second edge (EG2) extended in a second direction (e.g., y direction or -y direction).

[0230] A frame set (21) may be placed on a display panel (10). A frame set (21) may be placed at the rear of the display panel (10). In one embodiment, the frame set (21) may include a frame (21F), a wire (21WR), and an intermediate frame (21MF). The frame (21F) may have a body (21B), a head (21H), and a protruding pattern (21P). The body (21B) may extend in the longitudinal direction. The body (21B) may have a fixed point (21BF). The fixed point (21BF) may be a point where a part of the body (21B) is relatively fixed to the head (21H). The head (21H) may protrude from the body (21B) toward the rear of the display panel (10). The protruding pattern (21P) may protrude toward the rear of the display panel (10) and may be spaced apart from each other along the longitudinal direction of the frame (21F). In one embodiment, the protruding pattern (21P) may have a through hole (21PH).

[0231] The wire (21WR) may extend along the longitudinal direction of the frame (21F). The wire (21WR) may be secured to the head (21H). In one embodiment, the wire (21WR) may extend between the display panel (10) and the body (21B) and be secured to the head (21H). In one embodiment, the wire (21WR) may pass through a through hole (21PH).

[0232] An intermediate frame (21MF) may be positioned between the display panel (10) and the frame (21F). In one embodiment, the intermediate frame (21MF) may be positioned between a plurality of supporters (27) and the frame (21F). In one embodiment, the intermediate frame (21MF) may be fixed to a plurality of supporters (27).

[0233] Either the head (21H) or the intermediate frame (21MF) may have a concave portion (21CA) facing the other of the head (21H) and the intermediate frame (21MF). Additionally, the other of the head (21H) and the intermediate frame (21MF) may have a convex portion (21CB) facing the concave portion (21CA). For example, the head (21H) may have a concave portion (21CA), and the intermediate frame (21MF) may have a convex portion (21CB).

[0234] FIG. 13 is a side view showing the frame (21F) being bent by adjusting the length of the wire (21WR). FIG. 14 is a simulation result showing the frame (21F) being bent by adjusting the length of the wire (21WR).

[0235] Referring to FIGS. 13 and 14, the frame (21F) can be bent by adjusting the length of the wire (21WR). Additionally, the frame (21F) can bend the display panel (10).

[0236] The length of the wire (21WR) can be adjusted by a controller. If the length of the wire (21WR) is reduced, the frame (21F) may be bent. Since the wire (21WR) extends between the display panel (10) and the body (21B) and is fixed to the head (21H), it can apply a torsional moment to the frame (21F). Due to this torsional moment, the frame (21F) may be bent.

[0237] An intermediate frame (21MF) may be placed between the display panel (10) and the frame (21F). The intermediate frame (21MF) may prevent or reduce strain from being concentrated by the frame (21F) on at least some of the display panel (10) and / or the plurality of supporters (27).

[0238] When the frame (21F) is bent, the intermediate frame (21MF) can move relative to the head (21H). Since the intermediate frame (21MF) and the head (21H) may not be fixed to each other, the intermediate frame (21MF) can move relative to the head (21H). Therefore, the display panel (10) can be bent to a value less than or equal to a preset value and may not be damaged.

[0239] When the frame (21F) is bent, the convex portion (21CB) can move relative to the concave portion (21CA) at the concave portion (21CA). In this case, the concave portion (21CA) and the convex portion (21CB) can guide the head (21H) and the intermediate frame (21MF) to move relative to each other in one direction. Thus, the concave portion (21CA) and the convex portion (21CB) can increase the reliability of the frame set (21).

[0240] At least one of the plurality of supporters (27) can move in a third direction (e.g., z direction or -z direction). For example, among the plurality of supporters (27), the supporter (27) positioned adjacent to the first edge (EG1) can move in a third direction (e.g., z direction or -z direction). In one embodiment, the frame set (21) can move at least one of the plurality of supporters (27) in a third direction (e.g., z direction or -z direction). Thus, the display panel (10) can be bent.

[0241] FIG. 15 is a perspective view schematically showing the shape of a display device (1) that displays an image before it is bent. FIG. 16 and FIG. 17 are perspective views schematically showing the shape of a display device (1) that displays an image after it is bent. FIG. 16 is a perspective view showing the front of the display unit (1100), and FIG. 17 is a perspective view showing the rear of the display unit (1100).

[0242] Referring to FIG. 15, an image can be displayed in a display area (DA) of a display panel (10). The display panel (10) may include edges. In one embodiment, the display panel (10) may include a first edge (EG1) extended in a first direction (e.g., x direction or -x direction) and a second edge (EG2) extended in a second direction (e.g., y direction or -y direction).

[0243] When the first edge (EG1) extends in a first direction (e.g., x direction or -x direction) and the second edge (EG2) extends in a second direction (e.g., y direction or - direction), the display area (DA) of the display panel (10) may be a flat plane. When the display area (DA) is a flat plane, the sense of distortion can be prevented or reduced when multiple users view the image displayed on the display area (DA). Additionally, the sense of distortion felt by the user can be prevented or reduced even when viewing the image from various angles on the display device (1).

[0244] The controller (1700) may acquire information to bend the display panel (10). In one embodiment, the information acquired to bend the display panel (10) may be information corresponding to the operation of a remote control connected to the display device (1). In another embodiment, the information acquired to bend the display panel (10) may be information corresponding to the voice signal of a user viewing the video. In yet another embodiment, the information acquired to bend the display panel (10) may be information regarding the type of content included in the video. In yet another embodiment, the information acquired to bend the display panel (10) may be location information of at least one user viewing the video. For example, the location information of the at least one user may be the location information of a single user. As another example, the location information of the at least one user may be the location information of multiple users.

[0245] Referring to FIG. 16, the display panel (10) can be bent. In one embodiment, the first edge (EG1) may have curvature when the display panel (10) is bent. In this case, the position of a point on the second edge (EG2) may be changed in a first direction (e.g., x direction or -x direction). The position of a point on the second edge (EG2) may be changed in a direction closer to the center of the display panel (10). Additionally, the position of a point on the second edge (EG2) may be changed in a third direction (e.g., z direction or -z direction). In particular, the position of a point on the second edge (EG2) may be changed in the z direction of FIG. 16.

[0246] In one embodiment, when the display panel (10) is bent, the second edge (EG2) may have curvature. In this case, the position of a point on the first edge (EG1) may be changed in a second direction (e.g., the y direction or the -y direction). The position of a point on the first edge (EG1) may be changed in a direction closer to the center of the display panel (10). Additionally, the position of a point on the first edge (EG1) may be changed in a third direction (e.g., the z direction or the -z direction). In particular, the position of a point on the first edge (EG1) may be changed in the z direction of FIG. 16. Thus, the display panel (10) may be changed into a concave shape. In this case, the sense of presence and / or immersion felt by a user viewing an image displayed on the display area (DA) may be increased.

[0247] An embodiment of the present invention may include a state in which the display panel (10) is flat and a state in which the display panel (10) is bent to have a concave shape. Accordingly, the size of the space occupied by the display device (1) can be adjusted.

[0248] Meanwhile, although FIGS. 15 and 16 describe the display panel (10) changing from a flat shape to a concave shape, the display panel (10) can also change from a concave shape to a flat shape.

[0249] Referring to FIG. 17, a frame set (21) can bend a display panel (10). In one embodiment, a plurality of frame sets (21) may be provided. In other words, a frame set (21) may include a plurality of frame sets (21). In one embodiment, a plurality of frame sets (21) may include a first frame set (23) and a second frame set (25). In other words, a frame set (21) may include a first frame set (23) and a second frame set (25). In one embodiment, at least one of the first frame set (23) and the second frame set (25) may bend the display panel (10). In one embodiment, the first frame set (23) and the second frame set (25) may bend the display panel (10) such that a first edge (EG1) and a second edge (EG2) each have a curvature.

[0250] The first frame set (23) may be extended in a first direction (e.g., x direction or -x direction). The first frame set (23) may be bent from the first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). The first frame set (23) may be bent by being controlled by a controller (1700). Thus, the first frame set (23) may bend the display panel (10) from the first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). Additionally, the first frame set (23) may bend the display panel (10) such that the first edge (EG1) of the display panel (10) has curvature.

[0251] The second frame set (25) may be extended in a second direction (e.g., the y direction or the -y direction). The second frame set (25) may be bent from the second direction (e.g., the y direction or the -y direction) into a third direction (e.g., the z direction or the -z direction). The second frame set (25) may be bent by being controlled by a controller (1700). Thus, the second frame set (25) may bend the display panel (10) from the second direction (e.g., the y direction or the -y direction) into a third direction (e.g., the z direction or the -z direction). Additionally, the second frame set (25) may bend the display panel (10) such that the second edge (EG2) of the display panel (10) has curvature.

[0252] The wire (21WR) can bend the first frame set (23) and / or the second frame set (25). For example, if the wire (21WR) is retracted or the length of the wire (21WR) is shortened by a motor, the first frame set (23) and / or the second frame set (25) can be bent.

[0253] In one embodiment, the wire (21WR) may include a first wire (21WR1), a second wire (21WR2), a third wire (21WR3), and a fourth wire (21WR4). In one embodiment, the length of the first wire (21WR1), the length of the second wire (21WR2), the length of the third wire (21WR3), and the length of the fourth wire (21WR4) may be adjusted independently.

[0254] The first wire (21WR1) and the second wire (21WR2) can bend the frame included in the first frame set (23). In one embodiment, the length of the first wire (21WR1) and the length of the second wire (21WR2) can be adjusted independently. In this case, the degree of bending of the first frame set (23) extended in the -x direction and the degree of bending of the first frame set (23) extended in the x direction may be different. In one embodiment, the third wire (21WR3) and the fourth wire (21WR4) can bend the frame included in the second frame set (25). In one embodiment, the length of the third wire (21WR3) and the length of the fourth wire (21WR4) can be adjusted independently. In this case, the degree of bending of the second frame set (25) extended in the y direction and the degree of bending of the second frame set (25) extended in the -y direction may be different.

[0255] In one embodiment, a plurality of supporters (27) may be arranged side by side in a second direction (e.g., y direction or -y direction).

[0256] A plurality of supporters (27) can be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). In one embodiment, a first frame set (23) can bend a plurality of supporters (27) from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). For example, when the first frame set (23) is bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction), a plurality of supporters (27) can also be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction). Accordingly, the display panel (10) can be bent from a first direction (e.g., x direction or -x direction) to a third direction (e.g., z direction or -z direction).

[0257] At least one of the plurality of supporters (27) can move in a third direction (e.g., z direction or -z direction). For example, among the plurality of supporters (27), the supporter (27) positioned adjacent to the first edge (EG1) can move in a third direction (e.g., z direction or -z direction). In one embodiment, the second frame set (25) can move at least one of the plurality of supporters (27) in a third direction (e.g., z direction or -z direction). For example, when the second frame set (25) is bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction), at least one of the plurality of supporters (27) can move in a third direction (e.g., z direction or -z direction). Accordingly, the display panel (10) can be bent from a second direction (e.g., y direction or -y direction) to a third direction (e.g., z direction or -z direction).

[0258] In one embodiment, the controller (1700) may include a first drive unit (1710) and a second drive unit (1730). The first drive unit (1710) may control the frame assembly (20). In one embodiment, the first drive unit (1710) may control the bending of the first frame set (23) and / or the second frame set (25). In one embodiment, the first drive unit (1710) may include a motor. The motor may contract the wire (21WR) or wind the wire (21WR) to reduce the length of the wire (21WR).

[0259] In one embodiment, the first driving unit (1710) may include a plurality of motors. Each of the plurality of motors can control the bending of the first frame set (23) and the second frame set (25). In one embodiment, the plurality of motors can control the bending of a single frame set (21). For example, when the plurality of motors control the first frame set (23), the bending of both ends of the first frame set (23) can be controlled independently. The plurality of motors can each control the length of the first wire (21WR1) and the length of the second wire (21WR2). As another example, when the plurality of motors control the second frame set (25), the bending of both ends of the second frame set (25) can be controlled independently. The plurality of motors can each control the length of the third wire (21WR3) and the fourth wire (21WR4). Accordingly, the display panel (10) can be bent into various shapes.

[0260] The second driving unit (1730) can control the display unit (1100) to rotate around a second direction (e.g., y direction or -y direction) as an axis. In one embodiment, the second driving unit (1730) may include a motor. The motor can rotate the display unit (1100) around a second direction (e.g., y direction or -y direction) as an axis. Thus, the display panel (10) can be rotated around a second direction (e.g., y direction or -y direction) as an axis by the controller (1700).

In another embodiment, the first direction curvature of any one of the plurality of corner display areas may be different from the first direction curvature of another of the plurality of corner display areas. For example, the first direction first curvature (C11) of the first corner display area (CDA1) may be different from the first direction second curvature (C21) of the second corner display area (CDA2). The first direction first curvature (C11) of the first corner display area (CDA1) may be smaller or larger than the first direction second curvature (C21) of the second corner display area (CDA2). The first direction curvatures of the multiple corner display areas can be adjusted by the controller (1700) controlling the first frame set (23) of FIG. 17.

[0269] In one embodiment, the second-direction curvature of any one of the plurality of corner display areas may be the same as the second-direction curvature of another of the plurality of corner display areas. For example, the second-direction first curvature (C12) of the first corner display area (CDA1) may be the same as the second-direction second curvature (C22) of the second corner display area (CDA2). In another embodiment, the first-direction curvature of any one of the plurality of corner display areas may be different from the first-direction curvature of another of the plurality of corner display areas. For example, the second-direction first curvature (C12) of the first corner display area (CDA1) may be different from the second-direction second curvature (C22) of the second corner display area (CDA2). The second-direction first curvature (C12) of the first corner display area (CDA1) may be smaller or larger than the second-direction second curvature (C22) of the second corner display area (CDA2). The second direction curvatures of the multiple corner display areas can be adjusted by the controller (1700) controlling the second frame set (25) of FIG. 17.

[0270] The display panel (10) may include a structure and / or material capable of being stretched and / or contracted.

The controller (1700) may control the first frame set (23) and the second frame set (25) to bend the display panel (10) into various shapes.

[0271] FIG. 19 is an enlarged view of a portion of the display area of ​​a bent display panel (10) according to one embodiment. In FIG. 19, the same reference numerals as in FIG. 10 denote the same components, so redundant descriptions are omitted.

[0272] Referring to FIG. 19, the display panel (10) may have a penetration (TP) that penetrates the display panel (10). No components of the display panel (10) may be placed in the penetration (TP). Thus, the display panel (10) can be stretched and / or contracted without damage.

[0273] In one embodiment, the shape of the penetration portion (TP) in the bent display panel (10) may be modified. In the bent display panel (10), the angle (θ') between the edge (CAE1) of the first connection area (CA1) and the edge (PAE2) of the second pixel area (PA2) may be changed, the area or shape of the separation area (V') may be changed, and the position of the pixel area (PA) may also be changed.

[0274] Each pixel region (PA) can be rotated by a predetermined angle through a change in the aforementioned angle (θ'), an increase in the area of ​​the spacing region (V'), and / or a deformation of its shape. Due to the rotation of each pixel region (PA), the spacing between pixel regions (PA), for example, the first spacing (d1') and the second spacing (d2'), may differ depending on the position.

[0275] Stress may be generated in a first direction (e.g., x direction or -x direction), a second direction (e.g., y direction or -y direction), and / or a third direction (e.g., z direction or -z direction) of the bent display panel (10).
