[0048] Hereinafter, the technical idea and embodiments of the present invention will be described in more detail with reference to the attached drawings.
[0049] FIG. 1 is a plan view illustrating a curved display device according to one embodiment of the present invention.
[0050] FIG. 2 is a perspective view of a cover glass included in a curved display device according to one embodiment of the present invention.
[0051] Referring to FIGS. 1 and 2, a curved display device according to one embodiment of the present invention may include a cover glass (10); a housing (20); a main display module (not shown); and an auxiliary display module (not shown). The cover glass (10) may include a flat portion (D1) that is not curved and has a flat surface; and a curved portion (D2).
[0052] This curved portion (D2) may be a portion that extends from a pair of sides facing each other among the edges of the cover glass (10), but is gently bent toward the direction (Z direction) that the lower surface is facing. This pair of sides facing each other may be vertical sides. The remaining sides may be horizontal sides. This curved portion (D2) may be positioned on both sides of the cover glass (10) when the cover glass (10) is erected so that the thickness direction is perpendicular to the ground and the edge other than the curved portion (D2) contacts the ground. When the curved portions (D2) of the erected cover glass (10) are positioned on both sides, the user's fingers and gaze located in front of the cover glass (10) can easily reach the curved portions (D2), so that the touch-operable area can be expanded. Through this, the operability of a user using a curved display device according to an embodiment of the present invention can be increased.
[0053] The cover glass (10) of the curved display device according to one embodiment of the present invention may have at least one corner that is a curved portion (D2). Although two corners are illustrated as being curved portions (D2) in FIGS. 1 and 2 , this is not limited thereto, and one corner may be a curved portion (D2) as needed. At least two corners of the cover glass (10) of the curved display device according to one embodiment of the present invention may not be the curved portion (D2).
[0054] In a curved display device according to one embodiment of the present invention, the cover glass (10) may be integrally formed glass. However, the present invention is not limited thereto, and may not be integrally formed as needed. In addition, other materials may be used, or other materials may be combined with glass, as needed. For example, the cover glass (10) may be integrally formed of acrylic. For example, the cover glass (10) may be formed by bonding the glass and acrylic, with the flat portion (D1) being formed of glass and the curved portion (D2) being formed of acrylic.
[0055] In a curved display device according to one embodiment of the present invention, the cover glass (10) may include a touch sensing layer (TSL). This touch sensing layer (TSL) may be provided on the lower surface of the cover glass (10). This touch sensing layer (TSL) may be connected to a touch sensing device (not shown) housed in the housing (20) to detect a user's finger, etc. placed on the cover glass (10). The touch sensing method of this touch sensing layer (TSL) may employ a capacitive touch technology, but is not limited thereto, and may employ other touch technologies, for example, a pressure-sensitive or resistive touch technology.
[0056] In a curved display device according to an embodiment of the present invention, the housing (20) may support the cover glass (10) and provide a storage space for storing components necessary for the operation of the curved display device. In addition, the housing (20) may be coupled at least partially with components necessary for the operation of the curved display device. Through this coupling, components necessary for the operation of the curved display device may be arranged / fixed inside the housing (20). The housing (20) may include a bracket (21).
[0057] The bracket (21) may be arranged at a corner other than the curved portion (D2) of the cover glass (10). In one embodiment, the cover glass (10) may have a plurality of corners other than the curved portion (D2). In this case, the bracket (21) may be provided in a plurality to correspond to the corners other than the plurality of curved portions (D2). The bracket (21) may include a first plate, a second plate, and a third plate. The bracket (21) may have a shape in which the first plate and the second plate are spaced apart from each other and at least some of them are arranged to vertically overlap each other. In the bracket (21), any one of the corners of the first plate and any one of the corners of the second plate may be vertically aligned and may be respectively connected to facing corners of the third plate. That is, the bracket (21) may have a shape in which one edge of the first plate and one edge of the second plate, which are aligned vertically, are connected via the third plate. In this shape, the third plate connecting the first plate and the second plate may be an inner wall plate.
[0058] Alternatively, the shape of the bracket (21) may be such that one plate is folded twice, and the two folded directions are the same, so that the plates are spaced apart but at least partially face each other. Inside this shape, that is, between the plates facing each other, a part of the corner other than the curved portion (D2) of the cover glass (10) and a part of the housing (20) may be placed. The plates facing each other may be the first plate and the second plate. Among the first plate and the second plate, the plate adjacent to the cover glass (10) may be a top plate, and the remaining plates may be bottom plates. In one embodiment, the top plate may be connected to the cover glass (10). For example, the top plate may be in contact with the top surface of the cover glass (10). Alternatively, in some embodiments, the top plate may be indirectly connected to the top plate of the cover glass (10) with a cushioning material therebetween. Accordingly, when a user directs his / her gaze toward the top surface of the cover glass (10) of the curved display device according to an exemplary embodiment of the present invention, the bracket (21) can be observed. For example, at least a portion of the bracket (21) protruding beyond the top surface of the cover glass (10) from at least two edges of the cover glass (10) can be observed. At least a portion of the bracket (21) observed by the user may be a portion of the top plate.
[0059] FIG. 3 is a cross-sectional view taken along line X1-X1' of FIG. 1 of a curved display device according to one embodiment of the present invention. The cross-sectional view illustrated in FIG. 3 is a cross-sectional view of a corner of the curved display device other than the curved portion (D2).
[0060] Referring to FIG. 3, a curved display device according to one embodiment of the present invention may include the cover glass (10) and the housing (20). The housing (20) may include the bracket (21); a back cover (22); and a main display module.
[0061] The bracket (21) is arranged at a corner of the curved display device other than the curved portion (D2), and an area corresponding to the remaining plate of the bracket (21) that is not adjacent to the cover glass (10) among the two plates may be adjacent to the back cover (22) that covers the lower surface of the curved display device. In one embodiment, the back cover (22) may be coupled with the bracket (21). By this coupling, a storage space for various components arranged below the cover glass (10) may be provided. In addition, by this coupling, the installation position of the cover glass (10) that is at least partially connected to the bracket (21) may be fixed. This coupling may be implemented through a fastening member (not shown). This fastening member may be, for example, a screw. For the application of such a screw, a through hole corresponding to the screw may be provided that penetrates both the bracket (21) and the back cover (22) at a location where the bracket (21) and the back cover (22) come into contact. A screw thread for fastening the screw may be provided at a portion corresponding to the through hole in the bracket (21) or the back cover (22). When the bracket (21) and the back cover (22) are fastened through the screw and the screw thread, the opening of the housing (20) and the separation of each part required for internal inspection for maintenance of the curved display device become easy, and the reassembly performed after the internal inspection may become easy. However, the present invention is not limited thereto, and other fastening members / fastening means may be applied as needed. For example, means such as welding, ultrasonic bonding, or a member such as an adhesive may be used.
[0062] In Fig. 3, the edge of the cover glass (10) other than the curved portion (D2) is illustrated as being in contact with the inner side of the bracket (21) at one end (Y direction), but this is not limited thereto, and additional components may be further provided between the edge of the cover glass (10) and the inner side of the bracket (21) as needed. For example, a cushion that absorbs shock or vibration may be further provided between the edge of the cover glass (10) and the inner side of the bracket (21). For example, instead of a screw, a bolt and a nut may be provided as fastening members, and the threads inside the above-described through hole may be omitted.
[0063] According to one embodiment of the present invention, the bracket (21) may include at least one through hole in the inner wall plate, which is a portion connecting two plates facing each other and spaced apart from each other, to facilitate the inflow and outflow of air between the outside of the housing (20) and the inside of the housing (20). When the inflow and outflow of air between the outside of the housing (20) and the inside of the housing (20) is facilitated, the heat generated by the operation of the curved display device inside the housing (20) may be easily dissipated. This facilitated dissipation of heat may improve the operating life of the curved display device and reduce its failure rate. In Fig. 3, the through hole is illustrated as a circular shape extending in the Z direction. However, the present invention is not limited thereto, and the shape and number of the through holes may vary as needed. In addition, the through hole may be omitted as needed.
[0064] According to one embodiment of the present invention, the main display module may include a main display panel (231); a panel module case (230); a panel upper fixing portion (233); a panel lower support portion (232); and a double-sided tape (DST). The main display panel (231) may be a rectangular plate having a long side and a short side. The long side may be a longitudinal edge, and the short side may be a transverse edge. However, the present invention is not limited thereto, and the shape of the main display panel (231) may vary as needed. For example, the shape of the main display panel (231) may be a shape resembling a square with a small difference between the lengths of each side.
[0065] The main display panel (231) according to one embodiment of the present invention may be, for example, a display panel using LCD technology. If the main display panel (231) of a curved display device having a large screen is a display panel using LCD technology, the cost required to output an image corresponding to the entire large screen can be reduced because the maturity of LCD technology is high and unit cost reduction is advantageous. However, the present invention is not limited thereto, and a display panel using another technology may be used for the main display panel (231) as needed.
[0066] When LCD technology is used in the main display panel (231), a backlight unit (not shown) that provides light to the main display panel (231) within the panel module case (230) may be provided. The backlight unit may include a light source that emits light and components that guide the light to efficiently travel to the main display panel (231), such as a light guide plate or optical sheets.
[0067] The panel module case (230) is arranged below the main display panel (231) and can cover the lower surface and side surfaces of the main display panel (231). In addition, the panel module case (230) provides a storage space for other components required for driving the main display panel (231), and at least some of these other components can be combined. Through this combination, other components can be arranged / fixed inside the panel module case (230). The main display module may omit some of the components illustrated in FIG. 3 or may further include components not illustrated in FIG. 3.
[0068] For example, the main display module may further include an image processing circuit board including a processor for processing an image output to the main display panel (231). For example, when the main display panel (231) is a display panel using LCD technology, the main display module may further include a device that is arranged behind the main display panel (231) and spaced apart from the main display panel (231) and provides light. Thanks to the storage space provided by the panel module case (230), the distance required for arranging the device providing light can be easily secured.
[0069] The panel module case (230) can be coupled with the bracket (21). This coupling can be implemented through a fastening member (not shown). This fastening member can be, for example, a screw. For the application of this screw, a through hole corresponding to the screw can be provided that penetrates both the panel module case (230) and the bracket (21) at a location where the panel module case (230) and the bracket (21) come into contact. A screw thread for fastening the screw can be provided in the panel module case (230) or the inner wall plate. When the panel module case (230) and the bracket (21) are coupled through the screw and the screw thread, the main display module; and the main display panel (231) included therein; can be firmly supported. However, this is not limited thereto, and other fastening members / fastening means can be applied as needed. For example, means such as welding, ultrasonic bonding, or adhesives may be used. For example, bolts and nuts may be used as fastening members instead of screws, and the threads inside the aforementioned through-holes may be omitted.
[0070] According to FIG. 3, a spacer (SPC) is provided between the joint portion of the panel module case (230) and the bracket (21). When the spacer (SPC) is employed, the panel module case (230) and the bracket (21) can be firmly joined even when they are spaced apart. This possibility of separation can improve the design freedom of the panel module case (230). However, the present invention is not limited thereto, and the spacer (SPC) can be omitted as needed. The material of the panel module case (230) may be metal. However, the present invention is not limited thereto, and the material of the panel module case (230) can vary as needed. There are no restrictions on the materials that can be used as long as they can withstand the load of components such as the main display panel (231) and the like, such as a connecting means provided so that components can be placed / fixed therein, for example, a through hole having a screw thread. For example, reinforced plastic may be used in the panel module case (230).
[0071] The panel upper fixing part (233) and the panel lower support part (232) may be provided adjacent to the edge of the main display panel (231) inside the panel module case (230). At least a part of the panel upper fixing part (233) or the panel lower support part (232) may be positioned outside the interior of the panel module case (230). At least another part of the panel lower support part (232) may be in contact with the inner wall of the panel module case (230). However, the present invention is not limited thereto, and additional components may be further provided between the panel lower support part (232) and the inner wall of the panel module case (230) as needed. The panel lower support part (232) may be coupled to the inner wall of the panel module case (230). Such coupling means is not particularly limited. At least a portion of the lower panel support portion (232) can contact the lower edge of the main display panel (231) to support the main display panel (231) from the lower surface.
[0072] In FIG. 3, the cross-section of the panel lower support portion (232) with respect to a plane parallel to the Z direction and the Y direction at the same time is illustrated as having a rectangular region perpendicular to the thickness direction of the main display panel (231) (Y direction) and another rectangular region parallel to the thickness direction (Z direction) of the main display panel (231) connected nearly vertically, and having a step portion at one end of the rectangular region protruding in the horizontal direction (the direction opposite to the Y direction). In addition, a part of the upper surface of this step portion is illustrated as being in contact with the lower surface of the edge of the main display panel (231). However, this is merely an example for explanation and is not limited thereto, and the shape of the panel lower support portion (232) may vary as needed. As long as at least a part of the panel lower support portion (232) is coupled to the panel module case (230) and at least a part of it is in contact with the lower surface of the main display panel (231) to support the main display panel (231), the panel lower support portion (232) may have any shape. At least a part of the panel upper fixing part (233) may be in contact with the panel lower support part (232), and another part of the panel upper fixing part (233) may be in contact with the upper surface of the main display panel (231). The panel lower support part (232) and the panel upper fixing part (233) may be combined to create a space corresponding to the thickness of the main display panel (231). A part of a corner of the main display panel (231) may be inserted into this space. The area of the main display panel (231) to be inserted may be the remaining area excluding the area where an image is output.
[0073] In FIG. 3, the cross-section of the panel upper fixing member (233) with respect to a plane that is simultaneously parallel to the Z direction and the Y direction is illustrated as having a shape resembling a trapezoid without an angle at the upper corner. However, this is merely an example for convenience of explanation and is not limited thereto, and the cross-sectional shape of the panel upper fixing member (233) may vary as needed. As long as at least a portion of the panel upper fixing member (233) is in contact with the upper surface of the main display panel (231) and the other portion is combined with the panel lower support member (232) to fix the main display panel (231), the panel upper fixing member (233) may have any shape. The cover glass (10) may be arranged on the panel upper fixing member (233).
[0074] A double-sided tape (DST) may be provided between the upper portion of the panel upper fixing portion (233) and the lower surface of the edge of the cover glass (10). The cover glass (10) may have a touch sensing layer (TSL) on the lower surface of the cover glass (10), but may be positioned to avoid an area in contact with the double-sided tape (DST). That is, the double-sided tape (DST) may be in contact with the lower surface of the cover glass (10) while avoiding the touch sensing layer (TSL) of the cover glass (10). The double-sided tape (DST) may have, for example, a thickness and material that may exhibit elasticity, thereby compensating for an error that may exist between the cover glass (10) and the main display module and helping the cover glass (10) and the main display module to adhere closely to each other. Since the above cover glass (10) is supported by the main display module through the double-sided tape (DST), the support stability of the cover glass (10) can be improved.
[0075] The main display panel (231) may have an area where an image is output and an area where an image is not output. The area where an image is not output on the main display panel (231) may be located at the edge of the main display panel (231). The panel upper fixing part (233) may be positioned to avoid the area where an image of the main display panel (231) is output. That is, the panel upper fixing part (233) may be positioned in an area where an image of the main display panel (231) is not output. The width of the panel upper fixing part (233) parallel to the Y direction may correspond to the Y direction width of the area where an image of the main display panel (231) is not output. By this correspondence, the image output from the main display panel (231) may be suppressed from being obscured by the arrangement of the panel upper fixing part (233), and the image may be viewed by the user over the widest possible area by being integrated. However, it is not limited to this, and the width parallel to the Y direction of the upper panel fixing part (233) may vary as needed.
[0076] FIG. 4 is a perspective cross-sectional view taken along line X1-X1' of FIG. 1 in a curved display device according to one embodiment of the present invention. In the embodiment of FIG. 4, for convenience of explanation, differences from the embodiment of FIG. 3 will be mainly described, and parts not described follow the embodiment described above.
[0077] Referring to FIG. 4, a curved display device according to an embodiment of the present invention may provide a module case support disposed between the main display module and the bracket (21) or the back cover (22), unlike the above-described embodiment. At least a part of the module case support may be coupled by contact with the panel module case (230) of the main display module, and another part may be coupled by contact with the back cover (22) or the bracket (21). The module case support may include a first module case support (24A); and a second module case support (24B). At least a part of the first module case support (24A) may be coupled by contact with the panel module case (230) of the main display module, and another part may be coupled by contact with the bracket (21). At least a portion of the second module case support (24B) may be connected by contacting the panel module case (230), and another portion may be connected by contacting the back cover (22).
[0078] In Fig. 4, the first module case support (24A) in contact with the bracket (21) is illustrated as having a first bracket body that is arranged parallel to and adjacent to the inner wall plate of the bracket (21) and is coupled with the inner wall plate of the bracket (21); and a second bracket body that faces the panel module case (230) and is coupled with the lower surface of the panel module case (230). In addition, the first bracket body and the second bracket body are illustrated as being connected at an angle close to perpendicular to each other. In the first module case support (24A), an edge of the first bracket body opposite to an edge connected to the second bracket body can contact the lower edge of the cover glass (10) adjacent to the bracket (21). Through this contact, the first module case support (24A) can more firmly support / fix the cover glass (10). Among the corners of the second bracket body of the first module case support (24A), the opposite corner end of the corner connected to the first bracket body can come into contact with the lower surface of the panel module case (230).
[0079] In Fig. 4, the respective bodies of the first module case support (24A) are illustrated as being connected to the bracket (21), the panel module case (230), and the inner wall plate through a common through-hole having a screw thread, and a fastening member (not shown) connected to the through-hole. In this way, by connecting the two end bodies of the first module case support (24A) to the bracket (21) and the panel module case (230), respectively, the support stability of the cover glass (10) and the main display module can be improved. By providing the first module case support (24A), the degree of freedom with which the main display module can be arranged within the housing (20) can be improved. If a spacer (SPC) is provided between the inner wall plate of the bracket (21) and the panel module case (230), the degree of freedom with which the main display module can be arranged can be improved. In addition, when the first module case support (24A) is provided and the main display module is placed through the module case support, it is possible to stably place the bracket (21) and the panel module case (230) at a greater distance than when only a spacer (SPC) is provided between them and they are combined. In addition, among the module case supports, a part of the second module case support (24B) may be combined by contacting the panel module case (230) of the main display module, and another part may be combined by contacting the back cover (22).
[0080] In Fig. 4, the second module case support (24B) disposed between the lower portion of the main display module and the back cover (22) and in contact with the back cover (22) is illustrated as having a body facing the panel module case (230), and another body connected almost vertically to this body and adjacent to the upper surface of the back cover (22). In addition, a spacer (SPC) is further illustrated as being provided between the lower surface of the second module case support (24B) and the back cover (22). Through the coupling between the auxiliary display module and other components implemented through the second module case support (24B), even if the distance between the lower surface of the main display module and the back cover (22) is large, the support stability for the main display module can be improved. However, this is not limited to this, and the shape and arrangement of the first module case support (24A) and the second module case support (24B) may be changed as needed.
[0081] Any shape can be applied to the module case support as long as it provides a distance from the bracket (21) and the back cover (22) to the main display module, and can provide a combination of the main display module and the bracket (21), and a combination of the main display module and the back cover (22). At least one of the first module case support (24A) and the second module case support (24B) can be omitted as needed. The spacer (SPC) can be omitted as needed.
[0082] Fig. 5 is a cross-sectional view taken along line X2-X2' of Fig. 1 of a curved display device according to one embodiment of the present invention. The cross-sectional view illustrated in Fig. 5 is a cross-sectional view of a corner, which is the curved portion (D2), among the corners of the curved display device.
[0083] Referring to FIG. 5, the housing (20) may further include the auxiliary display module; and a cover side (26) in a portion corresponding to the curved portion (D2) of the cover glass (10) of the curved display device according to one embodiment of the present invention.
[0084] The above auxiliary display module may include: the auxiliary display panel (251) for providing image output to the curved portion (D2) of the cover glass (10); an auxiliary display guide (252) having a shape corresponding to the lower surface of the curved portion (D2) and supporting the auxiliary display panel (251); and an auxiliary display controller (251B) at least part of which is disposed between the auxiliary display guide (252) and the cover side (26). The cover side (26) may be disposed between the lower portion of the auxiliary display module and the main display module and the back cover (22).
[0085] The upper part of the cover side (26) may be in contact with and coupled to the main display module and the auxiliary display module, respectively, and the lower part of the cover side (26) may be in contact with and coupled to the back cover (22). Through this coupling, the support stability of the auxiliary display module disposed under the curved portion (D2) of the cover glass (10) and the main display module in contact therewith may be improved. This coupling may be implemented through a through-hole that commonly penetrates both parts in contact, a screw thread disposed inside the through-hole, and a fastening member inserted into the through-hole. This fastening member may be, for example, a screw. However, the present invention is not limited thereto, and other fastening members or fastening means may be used for the coupling as needed. For example, a fastening means such as welding or a fastening member such as an adhesive may be used. For example, instead of a screw, a bolt and a nut may be provided as the fastening member, and the screw thread inside the above-described through-hole may be omitted. The above auxiliary display guide (252) may include an arc region formed by a curved surface corresponding to the curved portion (D2); and a flat region which is a flat surface connected to one end of the arc region facing the back cover (22) and extending toward the center of the cover glass.
[0086] A cross-section of a plane parallel to the Z direction and the X direction of the auxiliary display guide (252) may resemble, for example, a J shape. At least a part of the auxiliary display controller (251B) may be placed below the flat area of the auxiliary display guide (252). A part of the flat area of the auxiliary display guide (252) may be in contact with the lower surface of the panel module case (230). An opposite edge of the flat area of the auxiliary display guide (252) that faces the edge that contacts the arc area may be in contact with the cover side (26). The shape of the arc may be an arc whose angle formed by both ends and the imaginary center is close to 90 degrees. The shape and degree of bending of the arc may be a shape corresponding to the lower surface of the curved portion (D2) of the cover glass (10).
[0087] The auxiliary display panel (251) may be arranged on the upper surface of the arc region of the auxiliary display guide (252). That is, at least a portion of the auxiliary display panel (251) may be arranged between the lower surface of the curved portion (D2) of the cover glass (10) and the upper surface of the portion corresponding to the arc of the auxiliary display guide (252). Accordingly, the auxiliary display panel (251) may be adjacent to the lower surface of the curved portion (D2) and may be bent along the lower surface of the curved portion (D2). A space may be formed between the lower portion of the portion corresponding to the arc of the auxiliary display guide (252) and the upper portion of the portion corresponding to the flat area of the auxiliary display guide (252). Other components not shown in FIG. 5 may be arranged in this space.
[0088] For example, a substrate related to the control of the auxiliary display panel (251) may be placed in this space. However, the cross-sectional shape of the auxiliary display guide (252) is not limited thereto and may be changed as needed. Various shapes may be applied to the auxiliary display guide (252) as long as the auxiliary display panel (251) can be supported from the lower surface of the auxiliary display panel (251) and brought into close contact with the lower surface of the curved portion (D2) of the cover glass (10), can be combined by contact with the cover side (26), and can provide a space in which the auxiliary display controller (251B) can be accommodated / placed.
[0089] The auxiliary display guide (252) may be made of a metal material. The metal may be, for example, aluminum having thermal conductivity and rigidity. If the auxiliary display guide (252) has rigidity, the structural stability of the curved display device supported by the auxiliary display guide (252) may be improved. In addition, if the auxiliary display guide (252) has thermal conductivity, heat generated from other electronic components positioned adjacent to the auxiliary display guide (252) may be transferred to other structural components positioned in contact with the auxiliary display guide (252). This improvement in heat transfer capability may extend the lifespan of electronic components included in the curved display device and reduce maintenance costs of the curved display device.
[0090] The above cover side (26) may have a shape having two plates that are adjacent to each other and arranged in a nearly parallel manner with a height difference and a nearly vertically bent portion connecting the adjacent edges of these plates. Among the areas corresponding to these two plates, the area corresponding to the plate closer to the cover glass (10) may be a first cover side plate portion, and the area corresponding to the remaining plate closer to the back cover (22) may be a second cover side plate portion. The area corresponding to the plate connecting the first cover side plate portion and the second cover side plate portion may be a third cover side plate portion.
[0091] For example, the cross-sectional shape of the cover side (26) with respect to a plane that is simultaneously parallel to the X-direction and the Z-direction may be a step shape having two treads and one riser connecting the two treads. In this step shape, the area corresponding to the upper tread may correspond to the first cover side plate portion, and the area corresponding to the lower tread may correspond to the second cover side plate portion. In this step shape, the riser may correspond to the third cover side plate portion.
[0092] The first cover side plate part can be in contact with and support the lower surface of the panel module case (230). The second cover side plate part can be arranged so that its upper surface faces the lower surface of the auxiliary display guide (252). The lower surface of one of both sides of the second cover side plate part can be arranged so that at least a portion thereof is in contact with the upper surface of the back cover (22). The third cover side plate part can be in contact with one end of the flat area of the auxiliary display guide (252). Among the second cover side plate parts of the cover side (26), an edge adjacent to the cover glass (10) can have a portion that is bent and protrudes toward the lower surface direction (Z direction) of the back cover (22).
[0093] The outer surface (X direction) of this protruding portion may be in contact with the cover glass (10) or the touch sensing layer (TSL) on the lower surface of the cover glass (10). In addition, the inner surface (opposite to the X direction) of this protruding portion may be in contact with the edge of the back cover (22). That is, the protruding portion of the cover side (26) may protrude further in the edge thickness direction (Z direction) than the back cover (22) and may be exposed to the outside of the curved display device. In order to prevent the thickness (Z direction) of the curved display device from increasing due to the overlapping of the exposed portion of the cover side (26) and the back cover (22), the edge of the back cover (22) adjacent to the cover glass (10) may be spaced apart from the cover glass (10). The gap formed by this separation may be filled with the protruding portion of the cover side (26). By making contact between the outer surface of the protruding portion of the cover side (26) and the lower surface of the cover glass (10), the cover side (26) can support the edge of the cover glass (10) and prevent the cover glass (10) from coming off. This coming off may be due to the weight of the cover glass (10) due to gravity.
[0094] This shape of the cover side (26) is only for convenience of explanation, and various shapes can be applied to the cover side (26) and the auxiliary display guide as long as it can contact and support the lower surface of the panel module case (230), contact the auxiliary display guide (252) in a horizontal direction to support the auxiliary display guide (252), contact the back cover (22) to support the back cover (22), and contact the corner of the curved portion (D2) of the cover glass (10) to support the cover glass (10).
[0095] For example, the second cover side plate portion may further have a rough portion to increase the surface area or to reduce the space formed by the gap with the lower surface of the auxiliary display guide (252). This rough portion may be formed, for example, to increase the mechanical strength by suppressing warpage of the second cover side plate portion. This rough portion may be a surface having concave and convex portions. This rough portion may be a surface having corrugations. This rough portion may be a surface having prominences and depressions. For example, in the cover side (26) auxiliary display guide, the area corresponding to the first cover side plate is omitted, and the upper part of the area corresponding to the third cover side plate or the part corresponding to the riser can come into contact with the panel module case (230) to support the panel module case (230).
[0096] At least a part of the auxiliary display controller (251B) may be disposed in a space formed by a gap between the upper surface of the second cover side plate portion of the cover side (26) and the lower surface of the auxiliary display guide (252). Another part of the auxiliary display controller (251B) may extend along the lower surface of the flat area toward a portion where the arc area of the auxiliary display guide (252) and the flat area are connected. The extended portion of the auxiliary display controller (251B) may be bent along a portion where the arc area of the auxiliary display guide (252) and the flat area are connected. The auxiliary display controller (251B) may be connected to one side of the sides of the auxiliary display panel (251) facing the back cover (22).
[0097] By connecting the auxiliary display panel (251) and the auxiliary display controller (251B), an image signal output to the auxiliary display panel (251) can be controlled / transmitted. In addition, among the plates of the auxiliary display controller (251B), an edge adjacent to the auxiliary display panel (251) and the cover glass (10) protrudes in a direction (opposite to the Z direction) toward the flat portion (D1) of the cover glass (10), and one end of this protrusion can be connected to the auxiliary display panel (251). That is, the protrusion of the auxiliary display controller (251B) can support the edge of the auxiliary display panel (251) that faces the edge of the curved portion (D2) of the auxiliary display panel (251) (in the X direction) that is arranged to correspond to the curved portion (D2) of the cover glass (10), thereby preventing the auxiliary display panel (251) from escaping. If necessary, the auxiliary display controller (251B) can come into contact with the lower surface of the flat area of the auxiliary display guide (252). However, the present invention is not limited thereto, and the shape and arrangement of the auxiliary display controller (251B) can be changed if necessary.
[0098] Among the auxiliary display controllers (251B), the area disposed below the flat area may have various components required for the operation of the auxiliary display controller (251B) disposed on at least one surface. These various components may include, for example, a display driver integrated circuit in the form of a chip; and circuits; etc. These various components may be disposed on a flexible substrate that can be bent along the space in which it is installed. That is, the auxiliary display controller (251B) may include a flexible substrate; and various components disposed on the above-described substrate. The flexible substrate may be a flexible printed circuit board.
[0099] In FIG. 5, the area of the auxiliary display controller (251B) disposed below the flat area is depicted as having a flat, nearly rectangular plate shape, but this is only for convenience of explanation, and other elements that may be disposed on one side of the plate are omitted. The surface and cross-sectional shapes of the auxiliary display controller (251B) according to one embodiment of the present invention may vary as needed and may include parts not depicted.
[0100] The above-described auxiliary display controller (251B) is bent along a portion where the arc region and the flat region of the above-described auxiliary display guide (252) are connected, and at least a portion of the above-described auxiliary display controller (251B) is disposed below the flat region, and the above-described various components are disposed in the region disposed below the flat region, thereby suppressing an increase in the thickness of the space between the display guide (252) and the lower surface of the cover glass (10), i.e., the space required for the arrangement of the auxiliary display panel (251). This suppression of the space can be achieved by having the components necessary for the operation of the above-described auxiliary display panel (251) be arranged in a concentrated manner in an region of the above-described auxiliary display controller (251B) that is spaced apart from the cover glass (10) and adjacent to the flat region.
[0101] The above auxiliary display panel (251) can be placed in close contact with the lower surface of the curved portion (D2) of the cover glass (10). This close contact can be implemented by having the upper surface of the arc region of the auxiliary display guide (252) placed on the lower surface of the auxiliary display panel (251) push and support the auxiliary display panel (251) from below toward the lower surface of the cover glass (10) (in the opposite direction to the Z direction).
[0102] The area where the auxiliary display panel (251) is arranged on the lower surface of the cover glass (10) may overlap at least a portion of the curved portion (D2) and the flat portion (D1). In the main display module arranged below the flat portion (D1) of the cover glass (10), the edge of the main display panel (231) may be an area where no image is output. This area may be a bezel or a black printing area of the main display panel (231).
[0103] The auxiliary display panel (251) that is arranged to overlap at least a portion of the flat portion (D1) beyond the curved portion (D2) of the cover glass (10) can cover an area where the image of the main display panel (231) is not output. When a user looks at the cover glass (10) from the top surface (front when the curved display device is placed on the floor with the edge of the housing, not the curved portion (D2), facing the ground), the area where the image of the main display panel (231) is not output can be covered by the edge of the auxiliary display panel (251) that extends beyond the curved portion (D2) and thus cannot be seen. In other words, the main display panel (231) and the auxiliary display panel (251) can be arranged so that at least a portion of each overlaps. In the area where the main display panel (231) and the auxiliary display panel (251) overlap, the auxiliary display panel (251) may be positioned above the main display panel (231). That is, in the area where the main display panel (231) and the auxiliary display panel (251) overlap, a part of the auxiliary display panel (251) may be positioned closer to the lower surface of the cover glass (10) than a part of the main display panel (231).
[0104] Due to this arrangement of the areas, from the user's perspective, the area of the image output through the cover glass (10) can be recognized as an image output from an area encompassing both the curved portion (D2) and the flat portion (D1) without a bezel. The edge of the auxiliary display panel (251) that covers at least a portion of the flat portion (D1) beyond the curved portion (D2) of the auxiliary display panel (251) may have the panel upper fixing member (233) disposed below it. A non-magnetic adhesive member (not shown) may be further disposed between the upper surface of the panel upper fixing member (233) and the lower surface of the auxiliary display panel (251). A non-magnetic adhesive member (not shown) may be further disposed between the upper surface of a portion corresponding to the arc of the auxiliary display guide (252) and the lower surface of the auxiliary display panel (251).
[0105] The auxiliary display panel (251) may be bonded to the auxiliary display guide (252) using a non-magnetic adhesive. The non-magnetic adhesive may achieve adhesion through means other than magnetic force. The means other than magnetic force may be, for example, a polymer bond. The non-magnetic adhesive may be a double-sided adhesive tape. The double-sided adhesive tape may be different from the double-sided tape (DST) disposed between the cover glass (10) and the panel upper fixing member (233) at a corner other than the curved portion (D2) illustrated in FIGS. 3 and 4. The non-magnetic adhesive disposed on the lower surface of the auxiliary display panel (251) may have a thin thickness in order to achieve close contact while reducing the thickness. However, it is not limited thereto, and if necessary, the non-magnetic adhesive material placed on the lower surface of the auxiliary display panel (251) may have thickness and elasticity, such as a double-sided tape (DST) placed between the cover glass (10) and the upper panel fixing portion (233) at the corner other than the curved portion (D2).
[0106] The non-magnetic adhesive member arranged on the lower surface of the auxiliary display panel (251) may have thermal conductivity. Since the non-magnetic adhesive member arranged on the lower surface of the auxiliary display panel (251) has thermal conductivity, heat generated during operation of the auxiliary display panel (251) may be transferred to the auxiliary display guide (252) with which it makes contact through the non-magnetic adhesive member. The heat transferred to the auxiliary display guide (252) may be transferred to the cover side (26) adjacent to the auxiliary display guide (252). The heat transferred to the cover side (26) may be transferred to the back cover (22) with which it makes contact with the cover side (26).
[0107] The heat generated during the operation of the auxiliary display panel (251) is transferred to the back cover (22) that comes into contact with the exterior of the curved display device, thereby effectively dissipating the heat generated from the auxiliary display panel (251). By effectively dissipating the heat generated during the operation of the auxiliary display panel (251), the lifespan of the auxiliary display panel (251) and the curved display device can be extended, and maintenance costs can be reduced.
[0108] The auxiliary display panel (251) may be a panel based on display technology that can be easily arranged on a curved surface and implemented with a thinner thickness than a conventional LCD. Such a panel may be, for example, a curved display panel manufactured with a predetermined curvature. Such a panel may be, for example, a flexible display panel that can be bent in response to the curvature of the portion on which it is installed. The display technology used in the auxiliary display panel may be, for example, LED technology. Such LED technology may be oLED (organic light emitting diode) technology or iLED (inorganic light emitting diode) technology. If such oLED technology or iLED technology is used, the thickness of the panel arranged on the curved portion (D2) may be thinned. In a curved display device according to an embodiment of the present invention, the auxiliary display panel (251) may be arranged to vertically overlap on the edge of the main display panel (231) in order to cover an area where the image of the main display panel (231) is not output.
[0109] An arrangement including such an overlap may cause a gap between the upper surface of the main display panel (231) and the lower surface of the flat portion (D1) of the cover glass (10). The larger the gap, the greater the discontinuity of the image perceived by the user through the cover glass (10). This gap may cause optical distortion in the image observed through the cover glass (10). In addition, the larger the gap, the more it may interfere with the user's perception of the images of the flat portion (D1) and the curved portion (D2) as a single image. As the thickness of the auxiliary display panel (251) disposed on the curved portion (D2) and employing oLED or iLED technology is reduced, the gap between the main display panel (231) and the lower surface of the cover glass (10) may be reduced. By reducing the distance between the upper surface of the main display panel (231) and the lower surface of the cover glass (10), the discontinuity of the image perceived through the cover glass (10) can be reduced. However, the technology that can be applied to the auxiliary display panel (251) is not limited to LED technology, and any display technology that can provide a panel that can be placed on a curved surface and implemented with a thinner thickness than a conventional LCD can be applied to the auxiliary display panel (251).
[0110] A touch sensing layer (TSL) may be disposed between the lower surface of the curved portion (D2) of the cover glass (10) and the auxiliary display panel (251). This touch sensing layer (TSL) may be integral with the touch sensing layer (TSL) disposed on the lower surface of the flat portion (D1). By disposing the touch sensing layer (TSL) on both the lower surfaces of the flat portion (D1) and the curved portion (D2), the cover glass (10) may provide interaction through a user's touch across the curved portion (D2) and the flat portion (D1). However, the present invention is not limited thereto, and the arrangement of the touch sensing layer (TSL) may vary as needed. For example, the touch sensing layer (TSL) disposed on the lower surface of the flat portion (D1) and the touch sensing layer (TSL) disposed on the lower surface of the curved portion (D2) may be separate touch sensing layers (TSL).
[0111] The contact portions between the auxiliary display guide (252) and the auxiliary display controller (251B); between the auxiliary display guide (252) and the cover side (26); and between the auxiliary display guide (252) and the auxiliary display controller (251B) may be coupled to each other. By this coupling, the structural stability between the above-described components may be improved. This coupling may be implemented through a fastening member (not shown). This fastening member may be, for example, a screw. For the application of this screw, a through-hole corresponding to the screw may be provided that penetrates all of the contacting portions between the above-described components. In the inner wall plate, a screw thread for fastening the screw may be provided at a portion corresponding to this through-hole. When the above-described components are joined by screws and threads, the opening of the housing (20) and the separation of each component required for internal inspection for maintenance of the curved display device can be facilitated, and reassembly performed after the internal inspection can be facilitated. However, this is not limited thereto, and other fastening members / fastening means can be applied as needed. For example, means such as welding, ultrasonic bonding, or adhesives can be used. For example, bolts and nuts can be provided as fastening members instead of screws, and the threads inside the above-described through-hole can be omitted.
[0112] Fig. 6 is a perspective cross-sectional view taken along line X2-X2' of Fig. 1 in a curved display device according to one embodiment of the present invention. In the embodiment of Fig. 6, for convenience of explanation, differences from the embodiment of Fig. 5 will be mainly described, and parts not described follow the embodiment described above.
[0113] Referring to FIG. 6, a curved display device according to one embodiment of the present invention may provide an auxiliary display guide (252V) disposed below the auxiliary display panel (251), unlike the above-described embodiment. The cross-section of the auxiliary display guide (252V) with respect to a plane parallel to both the Z direction and the X direction may further include, for example, an upper portion of another plate having an edge bent nearly vertically to an opposite edge that faces an edge contacting an arc area among the flat areas of the auxiliary display guide (252), wherein the opposite edge of the other plate may have a shape facing the arc area. In this auxiliary display guide (252V), an area corresponding to the flat area of the auxiliary display guide (252) of another embodiment may be a first flat area; and an area of the plates bonded to the first flat area that faces the first flat area may be a second flat area.
[0114] At least a portion of the lower surface of the second flat area may be in contact with the upper surface of the back cover (22). The auxiliary display guide (252V) having such a shape may be formed integrally. That is, the shape of the auxiliary display guide (252V) may be similar to the shape in which the cover side (26) with the portion corresponding to the first cover side plate portion omitted in the auxiliary display guide (252) is joined to the auxiliary display guide (252), as illustrated in FIG. 5. By providing the auxiliary display guide (252V) with the above-described shape, the structural function performed by the auxiliary display guide (252) illustrated in FIG. 5 in combination with the cover side (26) may be performed by the auxiliary display guide (252V) alone.
[0115] The above-described auxiliary display guide (252V) may be provided integrally. Since the auxiliary display guide (252V) has the above-described shape and is provided integrally, the number of components and assembly process steps required to form the curved portion (D2) of the curved display device can be reduced. This can improve productivity for manufacturing the curved display device. In addition, since the auxiliary display guide (252V) is provided integrally, the performance of transferring heat generated during the operation of the auxiliary display panel (251) and other electronic components to the back cover (22) can be improved.
[0116] In the cross-sectional shape of the auxiliary display guide (252V), the area of the second flat region may be smaller than the area of the region corresponding to the second cover side plate of another embodiment in which the auxiliary display guide (252) and the cover side (26) are used together as separate parts. That is, the cross-sectional length of the part corresponding to the second flat region of the auxiliary display guide (252V) may be shorter than the cross-sectional length of the flat region of the auxiliary display guide (252). In this case, the portion protruding downward (Z direction) of the edge adjacent to the cover glass (10), which was provided in the region corresponding to the second cover side plate of another embodiment in which the auxiliary display guide (252) and the cover side (26) are used together as separate parts, may not be provided in the auxiliary display guide (252V). In FIG. 5 where the auxiliary display guide (252) is applied, the protruding portion of the edge of the auxiliary display guide (252) adjacent to the cover glass (10) supports the edge of the cover glass (10) and prevents the cover glass (10) from coming off. In one embodiment where the auxiliary display guide (252V) is applied, this coming off prevention function can be performed by the back cover (22) having a deformed edge adjacent to the cover glass (10).
[0117] In an embodiment in which the auxiliary display guide (252V) is applied, the width (parallel to the X direction) of the portion corresponding to the second flat area of the auxiliary display guide (252V) is small, so that the edge of the second flat area may not be adjacent to the cover glass (10). In this case, the back cover (22) may extend further toward the edge of the cover glass (10) than in another embodiment in which the auxiliary display guide (252) and the cover side (26) are used together as separate parts.
[0118] An extended portion of the edge of the back cover (22) may be bent and protruded toward the flat portion (D1) of the cover glass (10) (in the opposite direction to the Z direction) while in contact with the lower surface of the cover glass (10). The outer surface (in the X direction) of this protruding portion may be in contact with the lower surface of the cover glass (10) and may support the cover glass (10), thereby improving the structural stability of the cover glass (10) and preventing the cover glass (10) from being pushed. By bending the edge of the back cover (22) used together with the auxiliary display guide (252V) toward the cover glass (10) toward the flat portion (D1) of the cover glass (10), an increase in the thickness (in the direction parallel to the Z direction) of the curved display device may be suppressed.
[0119] Fig. 7 is a perspective cross-sectional view taken along line X2-X2' of Fig. 1 in a curved display device according to one embodiment of the present invention. In the embodiment of Fig. 7, for convenience of explanation, differences from the embodiments of Figs. 5 and 6 will be mainly described, and parts not described follow the above-described embodiment.
[0120] Referring to FIG. 7, a curved display device according to an embodiment of the present invention may further include a clip (254) disposed in an area where the main display panel (231) and the auxiliary display panel (251) overlap. The clip (254) may be disposed such that two plates have a height difference and at least a portion overlaps, and an upper and lower pair of edges of each of the two plates are aligned to contact one vertical surface, such that the two vertically aligned edges are connected. The shape of the clip (254) may be such that one plate is folded twice at an angle close to the vertical, but the folded direction is the same so that at least some of the surfaces face each other. The cross-sectional shape of the clip (254) with respect to a plane spaced apart from each other and simultaneously parallel to the Z direction and the X direction may be, for example, a shape resembling a U but having angled edges.
[0121] In Fig. 7, each corner where two plates are connected in the cross-section of the clip (254) is illustrated as having a nearly vertical corner, but this is not limited thereto, and the cross-sectional shape of the clip (254) may vary as needed. For example, the portion connecting the two plates in the clip (254) may have a gently curved shape instead of an angle. The portion corresponding to the upper plate in the clip (254) may be located between the lower surface of the auxiliary display panel (251) and the upper surface of the panel upper fixing member (233). The portion corresponding to the lower plate in the clip (254) may be located between the lower surface of the panel upper fixing member (233) and the upper surface of the main display panel (231). The portion where the arrangement area of the clip (254) and the main display panel (231) overlap may be an area where no image is output from the main display panel (231). In the area where the main display panel (231) and the auxiliary display panel (251) overlap, the clip (254) supports the spaced portion between the lower surface of the auxiliary display panel (251) and the upper surface of the main display panel (231), thereby improving the structural stability of the curved display device.
[0122] Fig. 8 is a perspective view showing a curved display device according to an embodiment of the present invention. Fig. 9 is a perspective cross-sectional view taken along line X3-X3' of Fig. 8, showing a part of a curved display device according to an embodiment of the present invention. Fig. 10 is a perspective cross-sectional view taken along line X4-X4' of Fig. 8, showing a part of a curved display device according to an embodiment of the present invention. In this embodiment, for the convenience of explanation, differences from the above-described embodiments will be mainly described, and parts not described will follow the above-described embodiments.
[0123] Referring to FIGS. 8, 9, and 10, a curved display device according to an embodiment of the present invention may include the cover glass (10), a housing (20E), the main display module, the auxiliary display module, and a molding part (27). The housing (20E) may include a bracket (21V) and the back cover (22). The cover glass (10) may have a plurality of sides. The plurality of sides may include the horizontal sides that are opposite to each other and the vertical sides that are opposite to each other. The cover glass (10) may have the flat portion (D1) and the curved portion (D2). The vertical sides may correspond to the curved portion (D2). The bracket (21V) may be disposed on the sides of the cover glass (10) that correspond to the flat portion (D1). That is, the bracket (21V) may be disposed on the horizontal sides. The bracket (21V) may be placed on the remaining corners of the cover glass (10) other than the curved portion. The bracket (21V) may cover at least a portion of the side portions of the cover glass (10) corresponding to the horizontal sides. The bracket (21V) may be provided in multiple numbers so as to be placed corresponding to each of the horizontal sides.
[0124] The bracket (21V) may cover the side portions corresponding to the flat portion (D1) of the cover glass (10). In some embodiments, the bracket (21V) may be provided to be smaller than the side portion corresponding to the flat portion (D1) of the cover glass (10), so that a portion of the side portion of the cover glass (10) may be exposed. However, the present invention is not limited thereto, and in some embodiments, the bracket (21V) may be provided to be larger than the side portion corresponding to the flat portion (D1), so that the side portion of the cover glass (10) may be completely covered.
[0125] The above bracket (21V) may have a shape in which one plate is folded once. This folded shape may have two plates that are connected to each other. Among the two plates, the plate adjacent to the back cover (22) may be the bottom plate, and the other plate may be the inner wall plate. On the XZ plane, the angle between the two plates may be 90 degrees. The cross-sectional shape of the bracket (21V) with respect to the XZ plane may be an L-shape. However, embodiments of the present invention are not limited thereto. In some embodiments, the angle between the two plates may vary.
[0126] In the embodiments according to FIGS. 1, 3, and 4, the bracket (21) has the top plate, which is a plate that protrudes above the top surface of the cover glass (10) and is formed by further bending along the center direction of the cover glass (10). The top plate faces the top surface of the cover glass (10). In contrast, in the present embodiment, the bracket (21V) may not have the top surface of the bracket (21) since it is formed by bending a single plate once. That is, in the embodiment of FIG. 8, when a user stands in front of a curved display device installed on the ground and directs his / her gaze toward the top surface of the cover glass (10), the image shown through the cover glass (10) may not be obscured by the bracket (21V). That is, a curved display device employing the bracket (21V) can further increase the screen area provided to the user.
[0127] The molding portion (27) may be provided on a side corresponding to the curved portion (D2) of the cover glass (10). The molding portions (27) may be provided in plurality so as to be arranged corresponding to the vertical sides of the cover glass (10). The molding portions (27) may cover at least a portion of the side corresponding to the curved portion (D2) and at least a portion of the housing (20E). The molding portion (27) may extend along the curved portion (D2) of the cover glass (10). The molding portion (27) may have a plate shape having a long side and a short side, and may be a shape that is bent along an imaginary bending line formed in the center and parallel to the long side. The molding portion (27) may be bent along an edge where the cover glass (10) and the back cover (22) meet. The molding portion (27) may be shaped to surround at least a portion of the cover glass (10) and at least a portion of the housing (20E). The molding portion (27) may have an inner surface facing the cover glass (10) and the back cover (22) and an outer surface facing the inner surface. The inner surface may have a first inner surface adjacent to the cover glass (10) and a second inner surface adjacent to the back cover (22).
[0128] The first inner surface of the molding portion (27) may be connected to at least a portion of the cover glass (10). The second inner surface of the molding portion (27) may be connected to at least a portion of the back cover (22). In some embodiments, the second inner surface of the molding portion (27) may be connected to at least a portion of the back cover (22) and the cover side (26).
[0129] In one embodiment, an adhesive layer (AL) may be further disposed between the first inner surface of the molding part (27) and the cover glass (10). The adhesive layer (AL) may be further disposed between the second inner surface of the molding part (27) and the back cover (22). The adhesive layers (AL) may be provided in multiple numbers, and may be respectively provided on the first inner surface and the second inner surface. The adhesive layer (AL) provided on the first inner surface may be in contact with the cover glass (10). The adhesive layer (AL) provided on the second inner surface may be in contact with the back cover (22). In some embodiments, at least a portion of the cover side (26) may be in contact with the adhesive layer (AL). The adhesive layer (AL) may be a tape having adhesive properties on both sides. The adhesive layer (AL) may be the same as the double-sided tape (DST). Alternatively, the adhesive layer (AL) may be provided differently from the double-sided tape (DST).
[0130] The above cover glass (10) can be combined with the back cover (22) through the molding portion (27). That is, the means for supporting the cover glass (10) can be increased. As a result, detachment of the cover glass (10) can be prevented. As a result, the structural stability of the curved display device can be further improved.
[0131] The molding part (27) may have a groove (GV) on the second inner surface. The groove (GV) may be formed by being recessed from the surface of the second inner surface toward the outer surface. The groove (GV) may be formed by extending in the longitudinal direction of the molding part (27) along the vertical sides of the cover glass (10). The adhesive layer (AL) disposed on the second inner surface may be disposed on the second inner surface, avoiding the area where the groove (GV) is formed. The groove (GV) may have a long width and a short width. The short width of the groove (GV) may be greater than the thickness of the touch sensing layer (TSL). The groove (GV) may be disposed on the second inner surface, and may be disposed such that at least a portion of the groove (GV) horizontally overlaps one side of the touch sensing layer (TSL) corresponding to the curved portion (D2).
[0132] During the assembly or maintenance process of the curved display device, the touch sensing layer (TSL) can be temporarily moved so that a portion thereof protrudes (in the Z direction) beyond the back cover (22). The groove (GV) can provide a space in which at least a portion of the touch sensing layer (TSL) exposed beyond the back cover (22) can be temporarily positioned. By providing this space, damage to the touch sensing layer (TSL) caused by the two surfaces of the molding part (27) can be prevented. As a result, the effort required to remove the molding part (27) from the housing (20E) during the assembly or maintenance process of the curved display device can be reduced. In addition, by providing this space, external exposure of the touch sensing layer (TSL) can be prevented during the assembly or maintenance process of the curved display device.
[0133] In one embodiment, the molding portion (27) may be an injection molded product. The injection molded product may be made of at least one material selected from silicone, polycarbonate, and metal. However, embodiments of the present disclosure are not limited thereto. In some embodiments, the molding portion (27) may be formed using other methods.
[0134] FIG. 11 is a perspective cross-sectional view taken along line X4-X4' of FIG. 8, illustrating a portion of a curved display device according to one embodiment of the present invention. In this embodiment, for convenience of explanation, differences from the above-described embodiments will be mainly described, and parts not described will follow the above-described embodiments.
[0135] Referring to FIG. 11, in a curved display device according to an embodiment of the present invention, the housing (20E) may further include a module case support including a third module case support (24C). The third module case support (24C) may include at least five plates, and the at least five plates may be formed by being connected to each other. Specifically, the at least five plates may include a first plate facing the back cover (22); a second plate bent and connected to the first plate; a third plate bent and connected to the second plate; a fourth plate bent and connected to the third plate; and a fifth plate bent and connected to the fourth plate.
[0136] The first plate is positioned facing the back cover (22), and may be positioned between the lower surface of the panel module case (230) and the back cover (22). Although not shown, the first plate may be connected to other components such as the back cover (22). The first plate may have one side connected to the second plate.
[0137] The second plate may have an opposite side facing a side connected to the first plate. The second plate may be connected to the third plate through the opposite side. The second plate may be connected in a direction intersecting the first plate, and may intersect in a manner parallel to one side of the panel module case (230). In one embodiment, the second plate may be in contact with one side of the panel module case (230) to support the panel module case (230). The angle between the second plate and the first plate may be 90 degrees, but is not limited thereto. In some embodiments, the angle between the second plate and the first plate may vary.
[0138] The third plate may have an opposing side facing a side connected to the second plate. The third plate may be connected to the fourth plate through the opposing side. The third plate may be connected in a direction intersecting the second plate, and may intersect the inner wall plate of the bracket (21V) so as to be parallel to a portion corresponding to the flat portion (D1) of the cover glass (10). In one embodiment, the third plate may intersect the second plate so as to be perpendicular to the inner wall plate of the bracket (21V) and parallel to the first plate. The third plate and the first plate may not have a horizontally overlapping area. That is, the direction in which the second plate is bent in connection with the first plate may be parallel to but opposite to the direction in which the second plate is bent in connection with the third plate. The angle between the third plate and the second plate may be 90 degrees, but is not limited thereto. In some embodiments, the angle between the third plate and the second plate may vary.
[0139] The fourth plate may have an opposing side facing a side connected to the third plate. The fourth plate may be connected to the fifth plate through the opposing side. The fourth plate may be connected in a direction intersecting the third plate, and may intersect the third plate in a direction parallel to the inner wall plate of the bracket (21V). The fourth plate and the second plate may not have vertically overlapping areas. That is, the direction in which the third plate is bent when connected to the second plate may be parallel to but opposite to the direction in which the third plate is bent when connected to the fourth plate. In one embodiment, the fourth plate may be connected to the inner wall plate of the bracket (21V). The angle between the fourth plate and the third plate may be 90 degrees, but is not limited thereto. In some embodiments, the angle between the fourth plate and the third plate may vary.
[0140] The fifth plate may have an opposite side facing a side connected to the fourth plate. One end of the fifth plate including the opposite side may face the center of the cover glass (10). The fifth plate may be connected in a direction intersecting the fourth plate, and may intersect the fourth plate in a parallel manner with a portion corresponding to the flat portion (D1) of the cover glass (10). The fifth plate and the third plate may have a horizontally overlapping area. That is, the direction in which the fourth plate is bent when connected to the third plate may be the same direction as the direction in which the fourth plate is bent when connected to the fifth plate. The fifth plate may be connected to the lower surface of the cover glass (10). In one embodiment, the fifth plate may be in contact with the lower surface of the cover glass (10) to support the cover glass (10). The angle between the fifth plate and the fourth plate may be 90 degrees, but is not limited thereto. In some embodiments, the angle between the fifth plate and the fourth plate may vary.
[0141] Since the first, second, third, fourth, and fifth plates are connected, stress applied to any one of the first, second, third, fourth, and fifth plates can be transferred to and distributed to the other plates. For example, since the four sides are in contact with the inner wall plate of the bracket (21V) and the two plates are in contact with one side of the panel module case (230), when the curved display device is erected and installed, the weight of the components provided in the inner space of the panel module case (230) can be distributed to the bracket (21V) via the third module case support (24C). For example, if the fifth plate is connected to the lower surface of the cover glass (10) and the first plate is connected to the back cover (22), a portion of the weight of the cover glass (10) can be distributed to the back cover (22) via the third module case support (24C). As a result, the structural stability of the curved display device can be further improved.
[0142] When the top glass of a touch-enabled bezel-less display device has only a flat surface, the top glass of such a bezel-less display device may be supported at the corners with double-sided tape to provide visual consistency or prevent loss of touchable area. Devices that rely on double-sided tape for support / fixing the top glass may have reduced structural stability as they grow larger, and the risk of safety accidents due to the top glass detaching may increase. These safety accidents arise from the increasing load on the top glass as the screen size of such devices increases. Furthermore, when the top glass of a touch-enabled bezel-less display device includes curved corners, the panels positioned at these corners are secured using magnets. When panels positioned at these curved corners are supported / fixed using magnets, the curvature design range of the curved portions is greatly limited, and the manufacturing / assembly costs of the related structures also increase.
[0143] In contrast, a curved display device according to an embodiment of the present invention may include a support mechanism that improves the structural stability of the cover glass (10). By this support mechanism, the curved display device according to an embodiment of the present invention may have improved structural stability compared to a bezel-less display device disclosed in the related art. This support mechanism may be, for example, support by the bracket (21) having a portion protruding in front of the cover glass (10). Specifically, the cover glass (10) may be supported / fixed by the protruding portion of the bracket (21) that protrudes beyond the uppermost surface of the cover glass (10) at at least two corners other than the curved portion (D2) and has a portion that horizontally overlaps with the uppermost surface of the cover glass (10).
[0144] A support mechanism that a curved display device according to one embodiment of the present invention may include may be, for example, support by the main display module coupled with the bracket (21). The main display module is bonded to the lower surface of the flat portion (D1) of the cover glass (10) via a double-sided tape (DST). Since the main display module is coupled with the bracket (21), support / fixing can be performed through other parts of the cover glass (10) other than the corner area rather than the curved portion.
[0145] A support mechanism that a curved display device according to one embodiment of the present invention may include may be, for example, support by the back cover (22) coupled with the bracket (21). The bracket (21) having a portion that protrudes forward of and overlaps the cover glass (10) is also coupled with the main display module, and since the bracket (21) is coupled with the back cover (22), the load applied by the weight of the cover glass (10) can be distributed. Due to this distribution of the load, the structural stability of the curved display device according to one embodiment of the present invention can be improved.
[0146] When the above-described support mechanisms are combined and applied, the curved display device according to an embodiment of the present invention can have significantly improved structural stability compared to a bezel-less display device disclosed in the related art. In addition, the curved display device according to an embodiment of the present invention has improved structural stability of the curved portion, and since the panel of the curved portion (D2) is manufactured using a technology that can be easily placed on a curved surface, such as iLED technology or oLED technology, the degree of design freedom of the cover glass and corresponding components can be significantly increased. For example, the curvature of the cover glass (10) can have various values. That is, since the corresponding device shapes become more diverse, the product value of the curved display device can be improved.
[0147] In a curved display device according to one embodiment of the present invention, the touch sensing layer (TSL) may employ a capacitive touch technology, and may use a metal mesh as an electrode formed on the lower surface of the cover glass (10). If a metal mesh is used as the electrode of the touch sensing layer (TSL), it is possible to provide touch detection capability to a large-area display at a low cost compared to a conventional ITO (Indium Thin Oxide) transparent electrode. If a metal mesh is used as the electrode, the electrode may be configured, for example, by metal wires that are spaced apart from each other, and metal wires that are spaced apart from each other but are arranged orthogonally to these metal wires.
[0148] However, it is not limited thereto, and the metal mesh can be implemented in other ways as needed. For example, a plurality of engraved grooves may be formed in an area corresponding to the touch sensing layer (TSL) on the lower surface of the cover glass (10) and arranged spaced apart from each other, and grooves may be formed that are arranged spaced apart from each other but orthogonal to these grooves. By filling the inside of these grooves with metal, a metal mesh made of metal lines can be implemented on the cover glass (10) without adding to the thickness of the touch sensing layer (TSL).
[0149] In a curved display device according to one embodiment of the present invention, the metal mesh, which is an electrode of the touch sensing layer (TSL) disposed on the lower surface of the cover glass (10), may have a mesh size in an area corresponding to a flat portion (D1) and a mesh size corresponding to a curved portion (D2) that are different from each other. Each metal line constituting the metal mesh may be thin and spaced apart from each other, but may not be transparent.
[0150] When a user gazes at an area corresponding to the flat portion (D1), the angle formed between the user's line of sight and the top surface of the cover glass (10) may not be large. Since the angle formed between the user's line of sight and the top surface of the cover glass (10) is not large, the number of metal lines / metal wires recognized by the user may not be large, and the spacing between the metal lines / metal wires may not be small. Accordingly, the metal lines / metal wires may not be easily recognized when a user standing in front of the curved display device gazes at an area corresponding to the flat portion (D1). When a user standing in front of the curved display device is standing, the angle formed between the user's line of sight toward the center of the flat portion (D1) and the top surface of the cover glass (10) may be approximately 90 degrees. However, when the user gazes at an area corresponding to the curved portion (D2), the angle between the user's line of sight and the top surface of the cover glass (10) may be reduced. When a user gazes at an area corresponding to the curved portion (D2), the number of metal lines / metal wires may increase and the spacing between the metal lines / metal wires may decrease compared to when the user gazes at an area corresponding to the flat portion (D1). Accordingly, as the angle formed between the user's line of sight and the top surface of the cover glass (10) decreases, the density of the metal mesh exposed to the user's line of sight may increase even if the area observed by the user is the same. When the density of the metal mesh exposed to the user's line of sight increases, the probability that the metal mesh will be recognized by the user may increase. When the density of the metal mesh recognized by the user increases, a part of the image transmitted from the panel located behind the metal mesh (from the viewpoint of a user standing in front of the curved display device) and reaching the user may be obscured.
[0151] In a curved display device according to an embodiment of the present invention, the metal mesh, which is an electrode of the touch sensing layer (TSL) disposed on the lower surface of the cover glass (10), may have a mesh size in an area corresponding to the curved portion (D2) that is larger than a mesh size in an area corresponding to the flat portion (D1). In other words, the mesh density in the area corresponding to the curved portion (D2) may be smaller than the mesh density in the area corresponding to the flat portion (D1). In this way, when the mesh density in the area corresponding to the curved portion (D2) is smaller than the mesh density in the area corresponding to the flat portion (D1), an increase in the mesh density of the metal mesh perceived by the user can be compensated for by a decrease in the physical mesh density. Through this compensation of the mesh density, the visibility of an image reaching the user from the curved portion (D2) can be significantly improved even when a non-transparent metal mesh is used as an electrode.
[0152] The features of the embodiments described above may be combined and implemented as long as they do not conflict with each other. For example, the feature regarding the mesh size of the touch sensing layer (TSL) may be applied to the curved display devices of FIGS. 8 to 10.
[0153] Although the present invention has been described above with reference to various embodiments, it will be understood by those skilled in the art or having ordinary knowledge in the art that the present invention can be variously modified and changed within a scope that does not depart from the spirit and technical scope of the present invention as set forth in the claims to be described below.
[0154] Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the patent claims.
