Description

Display device

[0001] The present disclosure relates to a display device, and more specifically, to a display device in which a back cover is coupled to a frame.

[0002] As the information society develops, the demand for display devices is increasing in various forms. In response to this, various display devices such as LCD (Liquid Crystal Display Device), PDP (Plasma Display Panel), ELD (Electroluminescent Display), VFD (Vacuum Fluorescent Display), and OLED (Organic Light Emitting Diode) have recently been researched and are being used.

[0003] Among these, display devices using Organic Light Emitting Diodes (OLEDs) have superior brightness and viewing angle characteristics compared to liquid crystal display devices, and have the advantage of being able to be implemented as ultra-thin because they do not require a backlight unit.

[0004] Recently, active research is being conducted to improve the assembly structure of display devices while ensuring their rigidity.

[0005] Conventionally, leaf springs were used to connect the frame positioned at the rear of a display device and the back cover without screws. However, screws were required to attach the leaf springs to the frame. Consequently, there is a problem involving additional material and assembly costs associated with using screws.

[0006] Furthermore, there was a problem where deformation occurred in parts of the leaf spring, excluding those secured by screws, upon receiving an external impact. This could cause deformation at the point where the back cover is attached, resulting in poor connection between the frame and the back cover. Such an issue could lead to damage to the display device and cause psychological discomfort and anxiety for the user.

[0007] In addition, an assembly structure has been attempted to combine the frame and back cover without using screws; however, this results in a complex structure for maintaining the connection and an increase in manufacturing costs.

[0008] The technical problem of the present disclosure may be to provide a display device capable of solving the various problems of the prior art described above.

[0009] Another objective of the present disclosure may be to provide a display device that can easily combine a frame and a back cover.

Accordingly, the back cover (30) and the leaf spring (50) may be coupled, and the back cover (30) may not be disengaged from the rear of the frame (20).

[0061]

[0062] Referring to FIGS. 7 and FIGS. 8, the holder (40) will be described in detail.

[0063] Referring to FIG. 7, the holder (40) may be a pair of holders (40a, 40b) spaced apart from each other by a predetermined distance. These may be referred to as the first holder (40a) and the second holder (40b), respectively. Each holder (40) may be formed with a leg portion (41) protruding to the rear of the frame (20) and a holding portion (42) bent from the end of the leg portion (41) toward the other holder (40).

[0064] The leg portion (41) may be formed by protruding in a direction perpendicular to the rear surface of the frame (20). Alternatively, the leg portion (41) may be formed by extending at an angle to the rear surface of the frame (20). The leg portion (41) may be a rectangular plate. The surfaces of the leg portions (41) facing each other may be referred to as inner surfaces.

[0065] The holding portion (42) may be formed by bending it parallel to the frame (20). The holding portion (42) may be a rectangular plate. The surface of the holding portion (42) facing the frame (20) may be referred to as the inner surface. The connection between the leg portion (41) and the holding portion (42) may be rounded.

[0066] The holder (40) may be formed by pressing at least a portion of the frame (20). Accordingly, an opening (21) may be formed in the frame (20) facing the inner surface of the holder (40). For example, in the case of a pair of holders (40a, 40b) consisting of a first holder (40a) and a second holder (40b), a first opening (21a) may be formed in the frame (20) facing the inner surface of the first holder (40a), and a second opening (21b) may be formed in the frame (20) facing the inner surface of the second holder (40b).

[0067] An opening hole (24) may be formed by opening a part of the frame (20). An opening hole (24) may be formed in the frame (20) between the first holder (40a) and the second holder (40b). An opening hole (24) may be formed in the frame (20) between the first opening (21a) and the second opening (21b).

[0068]

[0069] FIG. 8 is a cross-sectional view of the holder (40) along the AA' line of FIG. 7.

[0070] Referring to FIG. 8, the first holder (40a) and the second holder (40b) may be spaced apart by a predetermined distance. The inner surface of the leg portion (41) of the first holder (40a) and the inner surface of the leg portion (41) of the second holder (40b) may be spaced apart by a predetermined distance. This distance may be referred to as the holder width (W1).

[0071] The inner surface of the holding part (42) can form a separation distance from the rear surface of the frame (20) facing it. The separation distance can be referred to as the holder gap (h1).

[0072] A space in which a plate spring (50, see 6) is inserted may be formed between the inner surface of the leg portion (41) and the holding portion (42) and the rear surface of the frame (20). The size of the space may be determined by the holder width (W1) and the holder spacing (h1).

[0073] Since the holder (40) can be formed by press stamping, the thickness (t1) of the holding portion may be equal to the thickness of the frame (20). The thickness of the frame (20) may be 0.6T.

[0074]

[0075] Referring to FIGS. 9 to 12, the leaf spring (50) will be described in detail.

[0076] Referring to FIG. 9, the plate spring (50) may be formed by folding a single spring plate into three layers. The plate spring (50) may include a first plate body (51) in contact with a frame (20, see FIG. 7), a second plate body (52) laminated to the first plate body (51), and a third plate body (53) positioned in a direction opposite to the first plate body (51) with respect to the second plate body (52). The first plate body (51), the second plate body (52), and the third plate body (53) may be flat plates.

[0077] A first bend portion (b1) may be formed between the first plate body (51) and the second plate body (52). A first bend portion (b1) may be formed at one end of the first plate body (51) and one end of the second plate body (52). A second bend portion (b2) may be formed between the second plate body (52) and the third plate body (53). A second bend portion (b2) may be formed at the other end of the second plate body (52) and one end of the third plate body (53).

[0078] The first bending portion (b1) may include a guide portion (55) that protrudes from one end of the first plate body (51) toward the back cover (30) to form an inclined surface (59), and then extends to one end of the second plate body (52) in a direction opposite to the direction of protrusion. The first plate body (51) and the inclined surface (59) may form an acute angle. The second bending portion (b2) may come into contact with the free end of the first plate body (51).

[0079] The first plate (51) may be square in shape. The surface of the first plate (51) that contacts the frame (20, see FIG. 7) may be referred to as the outer surface.

[0080] The second plate (52) may have a square shape. The second plate (52) may come into contact with the first plate (51). The second plate (52) may come into contact with the first plate (51) to improve the torsional and bending rigidity of the plate spring (50).

[0081] The third plate (53) can be connected to the other end of the second plate (52). The side opposite to the side of the third plate (53) facing the second plate (52) can be referred to as the outer side. The third plate (53) can be in contact with the second plate (52) to improve the torsional and bending rigidity of the plate spring (50).

[0082] The plate spring (50) may include a folding portion (56). The folding portion (56) may be formed by folding so that an extension protruding outward from a portion of one side of the third plate body (53) is stacked on the outer surface of the third plate body (53). For example, the folding portion (56) may be formed by folding in the opposite direction of the second plate body (52) so as to contact the third plate body (53) after a portion of the side of the third plate body (53) is extended. The folding portion (56) may be positioned at the free end of the third plate body (53).

[0083] The folding portion (56) may include a third bending portion (57) and a rigid portion (58). The rigid portion (58) may be a part of the folding portion (56) that contacts the third plate body (53) in parallel. The torsional and bending rigidity of the plate spring (50) may be improved by the rigid portion (58). The third bending portion (57) may be a connecting portion between the rigid portion (58) and the third plate body (53). Since the folding portion (56) may be formed by extending from one side of the third plate body (53) and then folding, the third bending portion (57) may protrude to one side of the third plate body (53).

[0084] The folding section (56) may include a pair of folding sections (56a, 56b) spaced apart from each other by a predetermined distance. These may be referred to as the first folding section (56a) and the second folding section (56b), respectively. Each folding section (56) may be formed by folding in the direction of the other folding section (56) in a direction that intersects with the direction in which the leaf spring (50) is folded.

[0085]

[0086] Referring to FIG. 10, the first plate body (51) can form a stopper (54). The outer surface of the first plate body (51) may have a portion protruding to form the stopper (54). The stopper (54) may be formed in the center of the first plate body (51).

[0087] The length of the direction intersecting the folded direction of the leaf spring (50) can be referred to as the leaf spring width (W2). The widths of the first plate body (51), the second plate body (52), and the third plate body (53) may be the same as the leaf spring width (W2). Among the leaf springs (50), the portion where the folding portion (56, see FIG. 9) is formed may have a width greater than the leaf spring width (W2) due to the protruding third bend portion (57).

[0088]

[0089] Referring to FIG. 11, the thicknesses (t2, t3, t4) of the first plate (51), the second plate (52), and the third plate (53) may be the same. The thickness may be 0.4T.

[0090] The thickness of the third bend (57) may be equal to the sum of the thickness (t4) of the third plate (53) and the thickness (t5) of the rigid part (58).

[0091] The length (L1) of the first plate (51) may be longer than the length (L2) of the second plate (52). The length of the first plate (51), excluding the area where the first plate (51) and the guide part (55) face each other, may be equal to the length (L2) of the second plate (52).

[0092] The length (L3) of the third plate (53) may be equal to or smaller than the length (L2) of the second plate (52). Accordingly, when the third plate (53) comes into contact with the second plate (52), the third plate (53) may not come into contact with the guide portion (55).

[0093] The length (L4) of the folding portion (56) in the direction intersecting the direction in which the folding portion (56) is extended may be shorter than half the length (L3) of the third plate (53).

[0094] The sum of the thickness (t2) of the first plate (51), the thickness (t3) of the second plate (52), and the thickness (t4) of the third plate (53) can be called the insertion thickness (ti). The length obtained by subtracting the length (L4) of the folding part (56) from the length (L3) of the third plate (53) can be called the insertion length (L5).

[0095] The second bending portion (b2) can be bent so that the second plate body (52) and the third plate body (53) form a predetermined angle of inclination (theta1). The angle of inclination (theta1) may be an acute angle. Accordingly, a gap may be formed between the second plate body (52) and the third plate body (53). For example, a space may be formed in which the third plate body (53) can be elastically deformed to come into contact with the second plate body (52).

[0096]

[0097] FIG. 12 is a cross-sectional view of the stopper (54) along the BB' line of FIG. 10.

[0098] Referring to FIG. 12, the stopper (54) may be formed by pressing a part of the plate spring (50). The stopper (54) may be formed by pressing the first plate body (51). By pressing, a stopper hole (S) may be formed in the first plate body (51). The stopper hole (S) may be formed adjacent to the stopper (54).

[0099] The stopper (54) may be formed to be inclined toward one end from the other end opposite to one end of the first plate body (51). The end of the stopper (54) may be spaced apart from the first plate body (51) and / or the second plate body (52) by a predetermined distance. Accordingly, a space may be formed in which the stopper (54) elastically deforms to come closer to the second plate body (52). The space may be a stopper hole (S).

[0100] The length (L6) of the stopper (54) protruding from the first plate (51) may be equal to or smaller than the thickness (t2) of the first plate (51).

[0101]

[0102] Referring to FIGS. 13 and 14, the combination of the leaf spring (50) and the holder (40) is described in detail.

[0103] Referring to FIG. 13, the leaf spring (50) can be inserted and coupled between the holder (40) and the frame (20). At least a portion of both sides of the leaf spring (50) can be inserted between the holding portion (42) and the frame (20). The end portion of the leaf spring (50) opposite the guide portion (55) can be pushed between the holder (40) and the frame (20) to be coupled.

[0104] The holder width (W1, see FIG. 8) may be equal to or slightly different from the leaf spring width (W2, see FIG. 10). Accordingly, the leaf spring (50) can be inserted only in the longitudinal direction of the holder (40), and rotation after insertion can be prevented.

[0105] The holder gap (h1) may be equal to or slightly different from the insertion thickness (ti). Accordingly, during the process of inserting the plate spring (50) between the holder (40) and the frame (20), the stopper (54, see FIG. 12) may be elastically deformed to come closer to the second plate body (52) (see FIG. 12). Even if the holder gap (h1) and the insertion thickness (ti) are equal and the stopper (54) protrudes from the first plate body (51), the plate spring (50) can be inserted without problems because it is elastically deformed by being pressed against the frame (20) during the process of inserting it into the holder (40).

[0106] During the process of inserting the plate spring (50) into the holder (40), the third plate body (53) may be elastically deformed. For example, the third plate body (53) may be elastically deformed to come into contact with the second plate body (52).

[0107] Since the third plate (53) has elasticity, it can generate an elastic force in a direction opposite to the deformation direction. Accordingly, the third plate (53) inserted into the holder (40) can come into contact with the inner surface of the holder (40). The third plate (53) can come into contact with the inner surface of the holding part (42).

[0108] Even when the inner surface of the third plate (53) and the holding part (42) come into contact, the third plate (53) may still remain in a deformed state, and an elastic force may act in the restoration direction. Accordingly, a vertical force may be generated between the inner surface of the third plate (53) and the holding part (42). Due to the vertical force, a frictional force may be generated between the third plate (53) and the holding part (42), and the inserted plate spring (50) may not come out of the holder (40). The plate spring (50) and the holder (40) can be firmly joined by the elastically deformable third plate (53).

[0109] Since the folding part (56) and the holder (40) have a certain thickness, the folding part (56) can prevent over-insertion of the leaf spring (50). The leaf spring (50) can be inserted between the holding part (42) and the frame (20) such that the folding part (56) is positioned on one side of the holding part (42). The side of the rigid part (58) and the side of the holding part (42) come into contact, thereby preventing over-insertion of the leaf spring (50).

[0110] The third bend (57) of the folding part (56) protruding laterally from the plate spring (50) and the leg part (41) of the holder (40) come into contact, thereby preventing over-insertion of the plate spring (50).

[0111] The length of the holder (40) may be equal to or smaller than the value obtained by subtracting the length (L4) of the folding part (56) from the length (L3) of the third plate body (53). For example, when a plate spring (50) is inserted into the holder (40), the end portion of the plate spring (50) facing the guide portion (55) may protrude outward from the holder (40). The smaller the difference between the value obtained by subtracting the length (L4) of the folding part (56) from the length (L3) of the third plate body (53) and the length of the holder (40), the more stably the holder (40) can support the plate spring (50).

[0112] The holder (40) can prevent the leaf spring (50) from twisting. The holder (40) can wrap around at least a portion of both sides of the leaf spring (50). The holder (40) can wrap around at least a portion of both sides of the first plate body (51), the second plate body (52), and the third plate body (53). Therefore, even if an external impact is applied, the stress acting on the leaf spring (50) is evenly distributed to the area in contact with the holder (40), thereby preventing deformation of the leaf spring (50).

[0113]

[0114] Referring to FIG. 14, the first plate body (51) can be supported by the rear surface of the frame (20). When the plate spring (50) is subjected to an external impact, the plate spring (50) can be prevented from being deformed forward by the frame (20). The outer surface of the first plate body (51) can be exposed forward through the first opening (21a) and the second opening (21b) formed in the frame (20).

[0115] A stopper (54) formed on the first plate body (51) can be inserted into the opening hole (24) of the frame (20). For example, the stopper (54), which was elastically deformed to insert the plate spring (50) between the holder (40, see FIG. 13) and the frame (20), can be restored. Upon restoration of the elastic deformation, the stopper (54) can protrude again from the first plate body (51) and come into contact with one side wall of the opening hole (24) to prevent the plate spring (50) from coming off.

[0116] The opening hole (24) may be formed at a position opposite to the folding part (56, see FIG. 13) based on the area where the folding part (56, see FIG. 13) and the holding part (42, see FIG. 13) meet. The stopper (54) may be in contact with the side wall of the opening hole (24) closest to the folding part. The end of the stopper (54) may be in contact with one side wall of the opening hole (24) opposite it.

[0117] Referring again to FIGS. 13 and 14, one side of the folding part (56) can come into contact with one side of the holding part (42). Correspondingly, the end portion of the stopper (54) and one side wall of the opening hole (24) can come into contact. Accordingly, the plate spring (50) cannot be over-inserted by the folding part (56) and cannot be disengaged by the stopper (54), so it can be firmly coupled with the frame (20).

[0118]

[0119] Referring to FIG. 15, the latch (60) may include a rib (61) and a hook (62).

[0120] The rib (61) may be formed by a portion of the back cover (30) protruding forward. The rib (61) may be in the shape of a square plate. The rib (61) may extend in a direction that intersects one end of the plate spring (50, see FIG. 6) on which the hook (62) is attached.

[0121] The hook (62) may be formed by protruding a portion of the rib (61). The hook (62) may protrude from the end portion of the rib (61) toward one end of the leaf spring (50). The hook (62) may be formed at the free end of the rib (61). The hook (62) may be formed to protrude in the opposite direction to the edge (31) of the back cover (30).

[0122] The rim (31) of the back cover (30) may include a first rim (31a), a second rim (31b), and a third rim (31c). The first rim (31a) may form the outermost rim (31) of the back cover (30). The second rim (31b) may be formed by protruding the front surface of the back cover (30) at a predetermined distance from the first rim (31a). The second rim (31b) may form the rim (31) of the back cover (30) on the inner side of the first rim (31a). The third rim (31c) may be formed by protruding the front surface of the back cover (30) at a predetermined distance from the second rim (31b). The third rim (31c) may form the rim (31) of the back cover (30) on the inner side of the second rim (31b). The second and third edges (31b, 31c) can improve the rigidity of the back cover (30). The second and third edges (31b, 31c) can be formed to protrude at a lower height than the first edge (31a).

[0123] A reinforcing rib (63) may be formed on the side opposite to the side where the hook (62) protrudes from the rib (61). The latch (60) may include the reinforcing rib (63). The reinforcing rib (63) may be formed by extending a portion of the front surface of the back cover (30) so as to be in contact with the rib (61).

[0124] The rigidity of the latch (60) can be improved by the reinforcing rib (63). The latch (60) may not undergo plastic deformation during the process of being joined to the leaf spring (50) by the reinforcing rib (63).

[0125] The surface opposite to the protruding side of the hook (62) of the rib (61) can be connected to the back cover (30) and the support rib (32). One end of the support rib (32) can be connected to at least the central part of the rib (61). The other end of the support rib (32) can be connected to the edge (31) of the back cover (30). The support rib (32) can be connected so as to intersect the extension direction of the rib (61). The support rib (32) can be connected so as to intersect the extension direction of the edge (31) of the back cover (30).

[0126]

[0127] Referring to FIG. 16, the hook (62) may include an inner surface (65) facing the front surface of the back cover (30). The inner surface (65) of the hook (62) may come into contact with the outer surface of one end of the leaf spring (50, see FIG. 6). The surface excluding the inner surface (65) of the hook (62) may be referred to as the outer surface (66). The outer surface (66) of the hook (62) may be formed to be rounded.

[0128] The support rib (32) may extend from the front surface of the back cover (30) to the free end of the rim (31) and the rib (61). The support rib (32) may improve the rigidity of the latch (60). Due to the support rib (32), the latch (60) may not be deformed in a direction intersecting the protruding direction of the rib (61) during the process of being coupled to the leaf spring (50).

[0129] A gap may be formed between the inner side (65) of the hook (62) and the front side of the back cover (30). The gap may be referred to as the hook height (h3).

[0130]

[0131] Referring to FIG. 17, the back cover (30) can be attached to the rear of the frame (20). To attach the back cover (30) to the frame (20), the user can apply force to the rear of the back cover (30). Accordingly, the outer surface (66) of the hook (62) can come into contact with the guide portion (55). The outer surface (66) of the hook (62) can come into contact with the inclined surface (59).

[0132] Meanwhile, the frame (20) may include a first body (21) and a second body (22). The first body (21) may be inclined or extended vertically with respect to the front surface of the frame (20). The second body (22) may be extended from the first body (21) parallel to the front surface of the frame (20). A holder (40) may be provided in the second body (22).

[0133] For example, the first plate body (51) is located at the rear of the second body (22) and can come into contact with the second body (22). Also, the guide portion (55) and the first plate body (51) in the area facing the guide portion (55) are located at the rear of the first body (21) and can be spaced apart from the first body (21) by a certain distance (g). Accordingly, the guide portion (55) and a part of the first plate body (51) facing the guide portion (55) can be elastically deformed toward the first body (21) by an external force or can return to their original position according to the elastic force. When the latch (60) is coupled to the plate spring (50) by a certain distance, a space in which the hook (62) is received can be formed.

[0134] A space may be formed between the inner surface (65) of the hook (62) and the front surface of the back cover (30). The larger the hook height (h3) of the latch (60), the larger the space may be formed. The height of the guide portion (55) of the leaf spring (50) may be smaller than the hook height (h3). Accordingly, when the back cover (30) is coupled to the leaf spring (50), the guide portion (55) of the leaf spring (50) may be accommodated in the space.

[0135]

[0136] Referring again to FIGS. 6 and FIGS. 17, when a user continuously applies force from the rear of the back cover (30), the hook (62) comes into contact with the inclined surface (59) and moves along the guide portion (55) toward the frame (20), and the hook (62) can be caught on the plate spring (50). The inner surface (65) of the hook (62) comes into contact with the outer surface of one end of the first plate body (51), thereby preventing the back cover (30) from coming off toward the rear of the frame (20).

[0137]

[0138] Referring to FIGS. 1 to 17, a display device (1) according to one aspect of the present disclosure comprises: a display panel (10); a frame (20) to which the display panel (10) is coupled to the front and a plate spring (50) is disposed at the rear; and a back cover (30) that covers the rear of the frame (20) and has a latch (60) protruding forward that is coupled to the plate spring (50), and a holder (40) protruding backward is formed on the frame (20), and a part of the plate spring (50) is inserted between the holder (40) and the frame (20) so that the plate spring (50) is coupled to the frame (20), and the latch (60) may include a rib (61) protruding forward from the back cover (30) and a hook (62) formed at the end of the rib (61) to engage with the plate spring (50).

[0143] In the process of the back cover (30) being coupled to the frame (20), the hook (62) is guided by contacting the inclined surface (59) and moves toward the frame (20), and then can be caught on the outer surface of one end of the first plate body (51).

[0144] The outer surface of the third plate (53) can come into contact with the inner surface of the holding part (42).

[0145] The second bending portion (b2) is bent so that the second plate (52) and the third plate (53) form a predetermined angle of inclination, and the third plate (53) is elastically deformed to be closer to the second plate (52) so that it can be inserted between the holder (40) and the frame (20).

[0146] The above plate spring (50) may include a folding portion (56) that is folded so that an extension portion protruding outward from a part of one side of the third plate body (53) is stacked on the outer surface of the third plate body (53).

[0147] The above leaf spring (50) may have parts of both sides of the leaf spring (50) inserted between the holding part (42) and the frame (20) so that the folding part (56) is located on one side of the holding part (42).

[0148] The above folding part (56) can be placed at the free end of the third plate body (53).

[0149] The above folding portion (56) includes a pair of folding portions (56) spaced apart from each other by a predetermined distance, and each folding portion (56) can be formed by being folded toward the other folding portion (56) in a direction that intersects with the direction in which the plate spring (50) is folded.

[0150] An opening hole (24) is formed in the above frame (20), and the first plate body (51) may be formed so that a stopper (54) protrudes, which is inserted into the opening hole (24) and contacts one side wall of the opening hole (24).

[0151] The stopper (54) is formed by pressing at the other end opposite to the one end of the first plate (51) so as to be inclined toward the one end, and the stopper (54) can be inserted into the opening hole (24) after its elastic deformation is restored.

[0152] The opening hole (24) is formed at a position opposite to the folding part (56) based on the area where the folding part (56) and the holding part (42) meet, and the stopper (54) can be in contact with the side wall of the opening hole (24) that is closest to the folding part (56).

[0153] The above rib (61) extends in a direction that intersects with one end of the plate spring (50) to which the hook (62) is attached, and the hook (62) protrudes from the end of the rib (61) toward one end of the plate spring (50) and may include an inner surface that contacts the outer surface of one end of the plate spring (50) and an outer surface formed in a rounded shape.
