[0036] According to one embodiment, the display device (1) may be a flat display device in which the display panel (10) that displays an image is a flat display device as shown in FIG. 1. The display device may be a curved display device in which the display panel is bent, or a bendable display device in which the display panel can be deformed from a flat surface to a curved surface or from a curved surface to a flat surface, or the curvature of the curved surface can be changed.

[0037] Referring to FIGS. 1 to 3, a display device (1) according to one embodiment may include a display panel (10), a backlight unit (20), a chassis assembly (e.g., a front chassis (30), a middle mold (40), and a rear chassis (50)), a back cover (60), an optical sheet (70), at least one circuit board assembly (80), and a cable (100).

[0038] According to one embodiment, a display panel (10) may be configured to display visual information such as images and / or videos. The display panel (10) may include an LCD panel. An LCD panel may display images using liquid crystals that exhibit optical properties according to changes in voltage and temperature. However, the present disclosure is not limited thereto, and the display panel (10) may include a light-emitting diode panel (LED panel) or an organic light-emitting diode panel (OLED panel).

[0039] According to one embodiment, a backlight unit (20) may be provided to provide light to a display panel (10). The backlight unit (20) may be positioned on the lower side (e.g., in the -Z-axis direction) of the display panel (10). The backlight unit (20) may irradiate light toward the display panel (10).

[0040] In the drawing, the display device (1) is depicted as a light-receiving (non-emissive) display device (Non-Emissive Display Apparatus) including a backlight unit (20), but this is merely exemplary and the display device (1) may be an emissive display device (Emissive Display Apparatus). If the display device (1) is an emissive display device, the backlight unit (20) may be omitted.

[0041] According to one embodiment, the backlight unit (20) may be an edge-type backlight unit in which a light source (22) is positioned on one of the four sides of the display panel (10). The display device may include a direct-type backlight unit in which a light source is positioned on the lower side of the display panel.

[0042] According to one embodiment, the backlight unit (20) may include a light source printed circuit board (21), a plurality of light sources (22) mounted (or disposed) on the light source printed circuit board (21), and an optical member (e.g., a light guide plate (23), and a reflective sheet (24)) disposed on a light path emitted from the plurality of light sources (22).

[0043] According to one embodiment, a plurality of light sources (22) may be mounted in a row on a substrate (e.g., a light source printed circuit board (21)) of a backlight unit (20). A circuit pattern, etc. for transmitting driving power and signals to the light sources (22) may be printed on the substrate (e.g., a light source printed circuit board (21)). In FIG. 2, the substrate (21) is shown as one, but is not limited thereto, and the substrate (21) may be provided in multiple numbers.

[0044] According to one embodiment, the light source (22) may include a light-emitting diode (LED). The LED may be provided in the form of a package in which an LED chip is mounted on a substrate and filled with resin. Meanwhile, a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL) may be used as the light source (22).

[0045] According to one embodiment, an optical member (e.g., a light guide plate (23), and a reflective sheet (24)) may be placed on the path of light emitted from a light source (22). The optical member (e.g., a light guide plate (23), and a reflective sheet (24)) may guide the direction of light propagation or improve optical properties.

[0046] According to one embodiment, the optical member may include a light guide plate (23) that evenly disperses light emitted from a light source (22) toward a display panel (10), and a reflector sheet (24) that reflects light to prevent light loss.

[0047] According to one embodiment, the light guide plate (23) may be formed from a PMMA (Poly Methyl Methacrylate Acrylate) material. The light guide plate (23) may be provided with a pattern to change the path of light. In an edge-type backlight unit, the light source (22) may be located on the side of the light guide plate (23). For example, the light source (22) may be positioned to correspond to at least one side (23c) of the four sides of the light guide plate (23). Light incident on the side of the light guide plate (23) may be scattered from a pattern formed on the rear surface (23b) of the light guide plate (23) and emitted through the front surface (23a) of the light guide plate (23). The light guide plate (23) may be positioned such that the side of the light guide plate (23) is spaced apart from the light source (22) by a predetermined distance to account for thermal expansion.

[0048] According to one embodiment, the reflective sheet (24) can reflect light emitted from a light source (22) so that light is not lost from the rear surface (23b) of the light guide plate (23). The reflective sheet (24) can be provided in various forms such as a sheet, film, or plate. For example, the reflective sheet (24) can be formed by coating a base material with a material having a high reflectivity. The base material may include at least one of stainless steel, brass, aluminum, and PET (polyethylene terephthalate). The high-reflection coating agent may include at least one of silver and TiO2.

[0049] According to one embodiment, an optical sheet (70) can improve the optical properties of a display device (1). The optical sheet (70) may be placed in front of the light guide plate (23) (e.g., in the +X-axis direction) to improve the optical properties of light emitted from the light guide plate (23). The optical sheet (70) may be placed between the light guide plate (23) and the display panel (10).

[0050] According to one embodiment, the optical sheet (70) may include a diffuser sheet (71) and a prism sheet (72).

[0051] According to one embodiment, the diffusion sheet (71) can disperse light to cancel out or minimize the pattern of the light guide plate (23). This is because, generally, the light guided through the light guide plate (23) enters the eye directly, so the pattern of the light guide plate (23) is visible to the eye as is.

[0052] According to one embodiment, the prism sheet (72) can improve light brightness by refocusing light whose brightness has decreased as it passes through the diffusion sheet (71). For example, the prism sheet (72) may be a high-brightness prism sheet, specifically a DBEF (Dual Brightness Enhancement Film) sheet.

[0053] According to one embodiment, a chassis assembly (e.g., front chassis (30), middle mold (40), and rear chassis (50)) may be provided to accommodate a display panel (10) and / or a backlight unit (20). A chassis assembly (e.g., front chassis (30), middle mold (40), and rear chassis (50)) may be provided to support a display panel (10) and / or a backlight unit (20).

[0054] According to one embodiment, the chassis assembly may include a front chassis (30), a middle mold (40), and a rear chassis (50).

[0055] According to one embodiment, the front chassis (30) may include an opening (31) for exposing a display panel (10).

[0056] According to one embodiment, the middle mold (40) may include a middle mold side (41) and an intermediate support (42) that protrudes inward from the middle mold side (41) to support the display panel (10) and the optical member and maintain a gap.

[0057] According to one embodiment, the rear chassis (50) can support the backlight unit (20). Various components of the display device (1), such as the front chassis (30) and the middle mold (40), can be fixedly supported on the rear chassis (50).

[0058] According to one embodiment, a substrate of the backlight unit (20) (e.g., a light source printed circuit board (21)) may be mounted on the front (51) of the rear chassis (50). For example, the rear chassis (50) may serve to dissipate heat generated from the light source (22) to the outside. The heat generated from the light source (22) is transferred to the rear chassis (50) via the substrate (e.g., a light source printed circuit board (21)) and can be dissipated from the rear chassis (50).

[0059] For example, the rear chassis (50) can be formed from various metal materials such as aluminum or stainless steel, which have good thermal conductivity, or plastic materials such as ABS (acrylonitrile butadiene styrene) resin. In addition, the substrate (e.g., light source printed circuit board (21)) can also be a metal PCB (printed circuit board) made of aluminum, which has good thermal conductivity.

[0060] According to one embodiment, at least one of the front chassis (30), the middle mold (40), and the rear chassis (50) may be omitted or formed integrally with each other.

[0061] According to one embodiment, the back cover (60) may be positioned to wrap around the chassis assembly (e.g., front chassis (30), middle mold (40), and rear chassis (50)) to protect and accommodate the chassis assembly (e.g., front chassis (30), middle mold (40), and rear chassis (50)). For example, the back cover (60) may be attached at the rear (e.g., in the -X-axis direction) of the rear chassis (50) of the chassis assembly (e.g., front chassis (30), middle mold (40), rear chassis (50)).

[0062] According to one embodiment, at least one circuit board assembly (e.g., printed circuit board assembly) (80) may be accommodated in a chassis assembly (e.g., front chassis (30), middle mold (40), and rear chassis (50)). The circuit board assembly (80) may be placed on the rear (52) of the rear chassis (50). For example, the circuit board assembly (80) may include an Integrated Circuit (IC) for wirelessly transmitting and receiving data, signals, or power. Although FIG. 3 is illustrated as having one circuit board assembly (80), the present disclosure is not limited thereto, and the circuit board assembly (80) may be provided in multiple numbers.

[0063] According to one embodiment, the circuit board assembly (80) may include a circuit board (82) and a connector (84) mounted on the circuit board (82).

[0064] According to one embodiment, the circuit board (82) may be a printed circuit board (PCB). The circuit board (82) may be configured to drive and control at least one of a display panel (10) or a backlight unit (20). The circuit board (82) may supply power for driving the display device (1) or control the operation of the display device (1). For example, the circuit board (82) may include at least one of a main board, a Switched Mode Power Supply (SMPS), or a source board. Various electronic components may be mounted on the circuit board (82) depending on the purpose.

[0065] According to one embodiment, the circuit board (82) may be provided by forming wiring with copper foil on a thin substrate made of an insulator such as epoxy resin or bakelite resin, and then printing lead resist on it. According to some embodiments, the circuit board (82) may include a plurality of circuit patterns. The circuit board (82) may be provided as a single layer as well as a multi-layer.

[0066] According to one embodiment, the connector (84) may be provided to electrically connect the cable (100) and the circuit board (80).

[0067] According to one embodiment, the cable (100) can be electrically connected to electronic components inside the display device (1). For example, the cable (100) can electrically connect the display panel (10) and the circuit board (82). For example, the cable (100) can electrically connect the backlight unit (20) and the circuit board (82). One end of the cable (100) is electrically connected to a connector (84) provided on the circuit board (82), and the other end of the cable (100) can be electrically connected to the display panel (10) or the backlight unit (20). The cable (100) can transmit various signals between the display panel (10) or the backlight unit (20) and the circuit board (82). In addition, the cable (100) can electrically connect a plurality of circuit board assemblies (80) to each other.

[0068] According to one embodiment, the cable (100) can be electrically connected to an electronic component (e.g., circuit board assembly (80)) inside the display device (1) in a state where at least a part (e.g., fixing body (122)) of the fixing part (120) described below is separated (or cut off) from the cable body (110) during the manufacture of the display device (1).

[0069] According to one embodiment, the cable (100) may have a structure that can be bent or folded at least once. For example, the cable (100) may include at least one of a Flexible Flat Cable (FFC) and a Flexible Printed Circuit Board (FPCB).

[0070] FIG. 4 is a plan view of one end portion of a cable according to one embodiment of the present disclosure.

[0071] FIG. 5 is a vertical cross-sectional view of a cable according to one embodiment of the present disclosure.

[0072] FIG. 6 is a plan view of one end portion of a cable according to one embodiment of the present disclosure.

[0073] The embodiments of FIGS. 4 to 6 can be optionally combined with the embodiments of FIGS. 1 to 3 and FIGS. 7 to 13.

[0074] The configuration of the cable (100a) of FIG. 6 may be all or partly the same as the configuration of the cable (100) of FIG. 1 to FIG. 4.

[0075] Referring to FIGS. 4 to 6, a cable (100) according to one embodiment may include a cable body (110) and a fixing part (120) that is at least partially connected to the cable body (110) so as to be detachable (or, removed, cut off).

[0076] According to one embodiment, the cable body (110) of the cable (100) may include a base layer (111), at least one conductor (112), a cover layer (113), a protective layer (114), and a reinforcing layer (115).

[0077] According to one embodiment, the base layer (111) may be formed by extending it to have a length and width set during the manufacturing process. The base layer (111) may be composed of a heat-bondable synthetic resin having mechanical strength such as tensile strength, as well as insulating properties (e.g., electrical insulation), heat resistance, flexibility, and resilience. For example, the base layer (111) may be selected from synthetic resins including nylon, acetate, and polyester resins. In addition, the base layer (111) may be composed of various materials capable of ensuring the bendability of the flexible flat cable. The base layer (111) may also be named the first insulating layer.

[0078] According to one embodiment, a conductor (or conductor) (112) may be placed on a base layer (111). When the extending direction (or length direction) of the base layer (111) is defined as the first direction, the conductor (112) may be arranged in a direction parallel to the extending direction (e.g., the first direction) of the base layer (111). When the width direction perpendicular to the length direction of the base layer (111) is defined as the second direction, a plurality of conductors (112) may be arranged relative to each other in the width direction (e.g., the second direction) of the base layer (111). Each conductor (112) may be arranged adjacent to each other in the width direction. Each conductor (112) may be arranged parallel to each other at a certain interval so as not to come into contact with each other. The conductor (112) may be made of a conductive material to transmit an electrical signal or current. For example, the conductor (112) may be made of a conductive material such as silver, copper, copper, nickel, cobalt, or a combination thereof. The cable (100) can be formed by placing the conductor (112), which is manufactured through a separate manufacturing process, on one side (e.g., the top side) of the base layer (111), covering it with a cover layer (113), and then applying pressure.

[0079] According to one embodiment, the conductor (112) may be formed by printing a conductive paste in a stripe shape on one surface of the base layer (111). For example, the conductive paste may use a composition mixed in a range of 50 to 70 weight% silver (Ag) filler content and 30 to 50 weight% binder content. In addition to the silver filler, the conductive paste may use various conductive materials such as copper (Cu) filler, a filler coated with silver on copper, or a combination of copper, nickel, cobalt, or various ratios thereof. The printing technique for forming the conductor (112) may be carried out through various methods such as gravure printing, inkjet printing, offset printing, silkscreen printing, and rotary screen printing.

[0080] According to one embodiment, the conductor (112) may include a conductive layer (112a) and a coating layer (112b). The coating layer (112b) may be provided to reinforce the corrosion resistance of the conductive layer (112a). For example, the conductive layer (112a) may be copper foil, and the coating layer (112b) may be nickel plating.

[0081] According to one embodiment, a cover layer (113) may be placed on a base layer (111) on which a conductor (112) is placed. The cover layer (113) may cover at least a portion of the conductor (112). For example, the cover layer (113) may prevent the conductor (112) from being exposed to the outside by covering the remaining portion of the conductor (112), excluding the portion of the conductor (112) covered by a connection terminal (e.g., a protective layer (114)). After covering at least a portion of the conductor (112) placed on one side of the base layer (111), the cover layer (113) may be bonded to the base layer (111) through a laminating process.

[0082] According to one embodiment, the cover layer (113) may be extended to have a length and width set in the manufacturing process, such as the base layer (111). The cover layer (113) covers the conductor (112) placed on the base layer (111) and may be formed to be narrower than the width of the base layer (111). The cover layer (113) may be composed of a heat-bondable synthetic resin having mechanical strength such as tensile strength, as well as insulating properties (e.g., electrical insulation), heat resistance, flexibility, and resilience. For example, the cover layer (113) may be selected from synthetic resins including nylon, acetate, and polyester resins. In addition, the cover layer (113) may be composed of various materials capable of ensuring the bendability of the flexible flat cable. The cover layer (113) may also be named a second insulating layer.

[0083] According to one embodiment, the protective layer (114) may be placed on a region of the conductor (112) where the cover layer (113) is not provided. For example, the protective layer (114) may be provided to prevent corrosion of a portion of the conductor (112) exposed to the outside. For example, the protective layer (114) may be a coating layer in which a material such as gold is plated on a portion of the conductor (112) exposed to the outside. The protective layer (114) may be named a connection terminal (114).

[0084] According to one embodiment, the reinforcing layer (115) may be placed on the other side (e.g., bottom) opposite to one side (e.g., top) of the base layer (111). The reinforcing layer (115) may be provided to reinforce the mechanical strength of the cable (100) when the cable (100) is bent or twisted. For example, the reinforcing layer (115) may be placed to span the cable body (110) and / or the fixing part (120) of the cable (100). In this case, the reinforcing layer (115) may prevent damage at the fastening part (110b) of the cable body (110) when the connector of the electronic component of the cable (100) is connected.

[0085] According to one embodiment, the cable body (110) may include a body portion (110a) and a fastening portion (110b) provided at both ends of the body portion (110a).

[0086] According to one embodiment, the body portion (110a) may be a part of the cable body (110) of the cable (100) in which the conductor (112) is not exposed to the outside.

[0087] According to one embodiment, the connecting portion (110b) may be a part of a cable body (110) comprising a connection terminal (e.g., a protective layer (114)) formed on the exposed wire (112) such that at least a portion of the wire (112) is exposed to the outside. The connecting portion (110b) may be a part of a cable body (110) that can be inserted into a connector (e.g., a connector (84) of FIG. 3) of a circuit board assembly (e.g., a circuit board assembly (80) of FIG. 3). The cable (100) may be electrically connected to a circuit board (e.g., a circuit board (82) of FIG. 3) of the circuit board assembly (80) through the connection terminal (e.g., a protective layer (114)) of the connecting portion (110b).

[0088] According to one embodiment, the fixing portion (120) may extend from the fastening portion (110b) of the cable body (110). The width of the fixing portion (120) may be substantially the same as the width of the fastening portion (110b) of the cable body (110).

[0089] According to one embodiment, the fixing part (120) may be provided as a pair. The pair of fixing parts (120) may include a first fixing part (e.g., the first fixing part (120a) of FIG. 10) connected to one end (e.g., the first end) of the cable body (110) and a second fixing part (e.g., the second fixing part (120b) of FIG. 10) connected to the other end (e.g., the second end) opposite to the one end of the cable body (110).

[0090] According to one embodiment, the fixing part (120) may include a cutting part (121) and a fixing part body (122).

[0091] According to one embodiment, the cut portion (121) may include a cut line (1211) that extends for a predetermined length along the connection portion between the fixed portion (e.g., the fixed portion body (122)) and the cable body (110). The cut line (1211) may be formed in at least one row and may include a plurality of holes (or grooves) spaced apart from each other. For example, the cut line (1211) may have a dot-line shape. For example, the cut line (1211) may be formed through a punching, slitting, or laser cutting process.

[0092] According to one embodiment, a cut line (1211) may be provided at the boundary between the fastening portion (110b) of the cable body (110) and the fixing portion body (122). The cut line (1211) may be positioned adjacent to a connection terminal (e.g., a protective layer (114)) at the fastening portion (110b) of the cable body (110). The cut line (1211) may be located between the connection terminal (e.g., a protective layer (114)) of the fastening portion (110b) and the fixing groove (1221). The cut line (1211) may extend along the width direction (e.g., a second direction) of the cable (100) from the left end (101) of the cable (100) to the right end (102).

[0093] According to one embodiment, the fixed body (122) may be connected to the cable body (110) in a way that allows it to be detachably (or cut). For example, the fixed body (122) may be separated from the cable body (110) by cutting. When an external force (e.g., torsional force or cutting force) is applied to the fixed part (120), the fixed body (122) may be separated from the cable body (110) by said external force. For example, when an external force is applied to the fixed part (120), the fixed body (122) may be separated from the cable body (110) along the cutting line (1211) of the cutting part (121).

[0094] According to one embodiment, the fixing body (122) may include a fixing groove (1221). A fixing projection (e.g., the fixing projection (220) of FIG. 10) of a cable tray (e.g., the cable tray (200) of FIG. 10) described later may be inserted into the fixing groove (1221). The cable (100) can be stably accommodated in the cable tray (200) through the fixing groove (1221). For example, the fixing groove (1221) may have a rectangular shape, but the present disclosure is not limited thereto.

[0095] According to one embodiment, the fixing grooves (1221a, 1221b) may be provided in a plurality as shown in FIG. 6. The fixing grooves (1221a, 1221b) may be provided as a pair spaced apart from each other on the fixing body (122a) of each fixing part (120a). In this case, the cable (100a) can be more stably accommodated in the cable tray by inserting the fixing projection of the cable tray corresponding to each fixing groove (1221a, 1221b).

[0096] According to one embodiment, the structure of the fixing part (120, 120a) may be substantially identical to the cable body (110) of the cable (100, 100a), except for the cut line (1211) and the fixing groove (1221). For example, the fixing part (120, 120a) may be a part of the cable body (110) that extends in the longitudinal direction (e.g., a first direction) from the cable body (110) of the cable (100, 100a) and is separable (or, removed, cut) from the cable body (110) through the cut part (121). In this case, the fixing part (120, 120a) may include at least one of a base layer (111), at least one conductor (112), a cover layer (113), a protective layer (114), or a reinforcing layer (115), as in the cable body (110) of the cable (100). For example, the fixed part (120, 120a) may be integrally formed extending from at least one of the base layer (111), at least one conductor (112), cover layer (113), protective layer (114), or reinforcing layer (115) of the cable body (110).

[0097] FIG. 7 is a plan view of one end portion of a cable according to one embodiment of the present disclosure.

[0098] The embodiment of FIG. 7 can be optionally combined with the embodiments of FIG. 1 to 6 and FIG. 8 to 13.

[0099] The configuration of the cable (100-1) in Fig. 7 may be all or partly the same as the configuration of the cable (100) in Figs. 1 to 5.

[0100] Referring to FIG. 7, a cable (100-1) according to one embodiment may include a cable body (110) and a fixing part (120-1) connected to the cable body (110) in a manner that at least a portion thereof can be detachably (or removed, cut off). According to one embodiment, the cable body (110) may include a body part (110a) and a fastening part (110b) provided at both ends of the body part (110a).

[0101] According to one embodiment, the fixing part (120-1) may include a cutting part (121-1) and a fixing part body (122).

[0102] According to one embodiment, the cut portion (121-1) may include one or more cut lines (1211) that extend along a predetermined section along the connection portion between the fixed portion (e.g., the fixed portion body (122)) and the cable body (110). The one or more cut lines (1211) may include a first cut line (1211a) and a second cut line (1211b). The first cut line (1211a) and the second cut line (1211b) may be arranged side by side with a cut groove (1212) described later in between. For example, the first cut line (1211a) may be arranged adjacent to the left end (101) of the cable (100-1). For example, the second cut line (1211b) may be arranged adjacent to the right end (102) of the cable (100-1).

[0103] According to one embodiment, the cutting portion (121-1) may include a cutting groove (1212) disposed between a first cutting line (1211a) and a second cutting line (1211b). The cutting groove (1212) may be provided at the boundary between the fixing portion (120-1) and the fastening portion (110b). The cutting groove (1212) may extend in the width direction (e.g., the second direction) of the cable (100-1). The width of the fixing portion (120-1) may be substantially equal to the sum of the width of one or more cutting lines (1211) and the width of the cutting groove (1212). The width of the cutting groove (1212) may be designed considering the external force (e.g., torsional force or cutting force) required when cutting the fixing portion body (122) through one or more cutting lines (1211). As illustrated in FIG. 7, the width of the cutting groove (1212) may be longer than the width of one or more cutting lines (1211). For example, by increasing the proportion of the width of the fixing part (120-1) occupied by the cutting groove (1212), the external force required to cut the fixing part body (122) through the cutting line (1211) can be reduced. In this case, the external force required to cut the fixing part body (122) is reduced, so that the fixing part body (122) can be separated (or removed, cut) from the cable body (110) of the cable (100-1) with less external force.

[0104] FIG. 8 is a plan view of one end portion of a cable according to one embodiment of the present disclosure.

[0107] Referring to FIG. 8, a cable (100-2) according to one embodiment may include a cable body (110) and a fixing part (120-2) that is at least partially connected to the cable body (110) so as to be detachable (or, removed, cut off). According to one embodiment, the cable body (110) may include a body part (110a) and a fastening part (110b) provided at both ends of the body part (110a).

[0108] According to one embodiment, the fixing part (120-2) may include a cutting part (121-2) and a fixing part body (122).

[0109] According to one embodiment, the cut portion (121-2) may include a cut line (1211) that extends for a predetermined distance along the connection portion between the fixed portion (e.g., the fixed portion body (122)) and the cable body (110).

[0110] According to one embodiment, the cut line (1211) may be positioned between the first cut groove (1213a) and the second cut groove (1213b) described later. For example, the cut line (1211) may be located at the center of the width of the fixing part (120-2).

[0111] According to one embodiment, the cutting portion (121-2) may include one or more cutting grooves (1213) provided at the boundary between the fixed portion body (122) and the fastening portion (110b). The cutting grooves (1213) may include a first cutting groove (1213a) and a second cutting groove (1213b). The first cutting groove (1213a) and the second cutting groove (1213b) may be arranged side by side with a cutting line (1211) between them. For example, the first cutting groove (1213a) may be arranged adjacent to the left end (101) of the cable (100-2). For example, the second cutting groove (1213b) may be arranged adjacent to the right end (102) of the cable (100-2).

[0112] According to one embodiment, the first cut groove (1213a) may be a space that is cut in the width direction of the fixing part (120-2) so that one side (e.g., the left side) of the fixing part (120-2) is open. For example, one end of the first cut groove (1213a) may be an open end, and the other end of the first cut groove (1213a) may be a fixed end that contacts the cut line (1211).

[0113] According to one embodiment, the second cut groove (1213b) may be a space that is cut in the width direction of the fixing part (120-2) and has an open side (e.g., right) opposite to the one side of the fixing part (120-2). For example, one end of the second cut groove (1213b) may be an open end, and the other end of the second cut groove (1213b) may be a fixed end that contacts the cut line (1211).

[0114] According to one embodiment, one or more cut grooves (1213) may extend in the width direction (e.g., second direction) of the cable (100-2). The width of the fixing part (120-2) may be substantially equal to the sum of the width of the cut line (1211) and the width of one or more cut grooves (1213).

[0115] FIG. 9 is a plan view showing a plurality of connected cables according to one embodiment of the present disclosure.

[0116] The embodiment of FIG. 9 can be optionally combined with the embodiments of FIG. 1 to 8 and FIG. 10 to 13.

[0117] The configuration of the cable (100-3) of FIG. 9 may be all or partly the same as the configuration of the cable (100) of FIG. 1 to FIG. 5.

[0118] According to one embodiment, the cable (100-3) may be provided from a manufacturer (or producer) in the form of a single band (or tape, film) in which a plurality of cables (100-3a, 100-3b) are connected to each other before being electrically connected to an electronic component (e.g., a display panel (10) or circuit board assembly (80) of FIG. 1). The cable (100-3) in the form of a single band in which the plurality of cables (100-3a, 100-3b) are connected to each other may be named a cable reel or a cable roll.

[0119] Referring to FIG. 9, each of the plurality of cables (100-3a, 100-3b) of the cable (100-3) according to one embodiment may include a cable body (110) and a fixing part (120-3) that is at least partially connected to the cable body (110) so as to be detachable (or, removed, cut off). According to one embodiment, the cable body (110) may include a body part (110a) and a fastening part (110b) provided at both ends of the body part (110a).

[0120] According to one embodiment, the fixing part (120-3) may include a cutting part (121) and a fixing part body (122).

[0121] According to one embodiment, the fixing part (120-3) may include a first fixing part (120-3a) that is cut off and connected to at least one end of the cable body (110), and a second fixing part (120-3b) that is cut off and connected to at least one end of the cable body (110). Each of the first fixing part (120-3a) and the second fixing part (120-3b) may include a cut line (1211). Each of the first fixing part (120-3a) and the second fixing part (120-3b) may include a fixing groove (1221).

[0122] According to one embodiment, the first fixing part (120-3a) and the second fixing part (120-3b) may be provided at positions opposite to each other in the width direction (e.g., second direction) of the cable (100-3) with respect to the cable body (110). For example, as shown in FIG. 9, the first fixing part (120-3a) may be connected to one end of the cable body (110) so as to be offset toward the right end (102) of the cable (100-3). For example, as shown in FIG. 9, the second fixing part (120-3b) may be connected to the other end of the cable body (110) so as to be offset toward the left end (101) of the cable (100-3).

[0123] According to one embodiment, the sum of the width of the first fixing part (120-3a) and the width of the second fixing part (120-3b) may be substantially the same as the width of the cable (100-3). The length of the first fixing part (120-3a) and the length of the second fixing part (120-3b) may be substantially the same. Each fixing part (e.g., the first fixing part (120-3a), and the second fixing part (120-3b)) of a plurality of cables (100-3a, 100-3b) connected to each other may interlock with each other. For example, each fixing part (e.g., the first fixing part (120-3a), and the second fixing part (120-3b)) of a plurality of cables (100-3a, 100-3b) connected to each other may have various interlocking structures, such as an uneven structure or a diagonal structure.

[0124] In the case of the fixing part (120-3) of the cable (100-3) according to the embodiment of FIG. 9, the width of the fixing part (120-3) may be narrower compared to the fixing parts (120, 120a, 120-1, 120-2) of the cables (100, 100a, 100-1, 100-2) according to each embodiment of FIG. 4 to 8. In this case, the manufacturing cost of the cable (100-3) may be reduced by substantially reducing the amount (or volume) of the fixing part (120-3) that is discarded when the fixing part (120-3) is cut.

[0125] FIG. 10 is a perspective view showing a plurality of cables loaded in a cable tray according to one embodiment of the present disclosure.

[0126] The embodiment of FIG. 10 can be optionally combined with the embodiments of FIG. 1 to 9 and FIG. 11 to 13.

[0127] According to one embodiment, a plurality of cables (100) may be loaded into a cable tray (200) for storage or transport. The plurality of cables (100) loaded into the cable tray (200) may be used in an automated manufacturing process of a display device (e.g., the display device (1) of FIGS. 1 and 2) through a pickup device (e.g., a robot).

[0128] Referring to FIG. 10, a cable tray (200) according to one embodiment may include a tray body (210) and one or more fixing protrusions (220).

[0129] According to one embodiment, the tray body (210) may have a flat shape, but the present disclosure is not limited thereto. For example, the tray body (210) may have a bowl shape.

[0130] According to one embodiment, one or more fixing protrusions (220) may protrude from one side (e.g., the top surface) of the tray body (210). For example, one or more fixing protrusions (220) may protrude vertically from one side of the tray body (210) and extend. One or more fixing protrusions (220) may be provided at a position corresponding to one or more fixing grooves (1221) of the fixing portion (120) of the cable (100).

[0131] According to one embodiment, the fixed projections (220) may be provided as a pair. The pair of fixed projections (220) may include a first fixed projection (220a) and a second fixed projection (220b). The pair of fixed projections (220a, 220b) may be spaced apart from each other. The pair of fixed projections (220a, 220b) may be positioned facing each other.

[0132] According to one embodiment, a cable (100) can be fixed on a cable tray (200) by inserting a fixing projection (220a, 220b) of a cable tray (200) corresponding to a fixing groove (1221) of a fixing part (120). For example, a plurality of cables (100) can be loaded vertically on the cable tray (200) through the fixing projection (220) of the cable tray (200). In this case, a plurality of cables (100) can be stably fixed and / or loaded by the fixing projection (220) of the cable tray (200), and twisting or bending of the cables (100) that may occur when transporting the cable tray (200) loaded with a plurality of cables (100) can be prevented.

[0133] According to one embodiment, each cable (100) among a plurality of cables (100) loaded in a cable tray (200) can be cut (or separated) through a cutting part (121) while each fixed part body (122) is fixed by a fixed projection (220) of the cable tray (200) during the process of being picked up by a pickup device (e.g., a robot), and an automated process of a display device (e.g., the display device (1) of FIG. 1 and FIG. 2) by the pickup device can be performed.

[0134] FIG. 11 is a perspective view showing a plurality of cables loaded in a cable tray according to one embodiment of the present disclosure.

[0135] The embodiment of FIG. 11 can be optionally combined with the embodiments of FIG. 1 to 10, FIG. 12, and FIG. 13.

[0136] The configuration of the cable tray (200-1) in Fig. 11 may be all or partly the same as the configuration of the cable tray (200) in Fig. 10.

[0137] Referring to FIG. 11, a cable tray (200-1) according to one embodiment may include a tray body (210) and one or more fixing protrusions (220-1).

[0138] According to one embodiment, the fixed protrusions (220-1) may be provided as a pair. The pair of fixed protrusions (220a-1, 220b-1) may be spaced apart from each other. The pair of fixed protrusions (220a-1, 220b-1) may be positioned facing each other.

[0139] According to one embodiment, each fixed projection (220a-1, 220b-1) may include an extension (221) extending vertically from one side of the tray body (210) and a stopper (222) bent from the extension (221). For example, the stopper (222) may extend in a direction different from the extension direction (e.g., vertical direction) of the extension (221) (e.g., vertical direction) (e.g., horizontal direction).

[0140] According to one embodiment, the stopper (222) may be bent vertically outward from the extension (221). For example, the stopper (222) of each fixed projection (220a-1, 220b-1) may be bent in opposite directions relative to each other (e.g., opposite horizontal directions). However, the present disclosure is not limited thereto. The stopper (222) may be formed with a plurality of cables (100) fixed (or inserted) in the extension (221) of the fixed projection (220-1).

[0141] According to one embodiment, the stopper (222) may be provided to restrict the vertical movement of the fixing part (120) of the cable (100) during the process in which each cable (100) among a plurality of cables (100) loaded in the cable tray (200-1) is picked up by a pickup device (e.g., a robot). In this case, each fixing part body (122) may be more easily cut (or separated) by the fixing projection (220-1) of the cable tray (200-1).

[0142] FIG. 12 is a perspective view showing a plurality of cables loaded in a cable tray according to one embodiment of the present disclosure.

[0143] The embodiment of FIG. 12 can be optionally combined with the embodiments of FIG. 1 to 11 and FIG. 13.

[0144] The configuration of the cable tray (200-2) in Fig. 12 may be all or partly the same as the configuration of the cable tray (200) in Fig. 10.

[0145] According to one embodiment, the cable (100') may be a bendable or foldable FFC or FPCB as described above. The cable (100') may be bent or folded at least once to avoid interference between counterparts depending on the arrangement between components within a display device (e.g., the display device (1) of FIG. 1 and FIG. 2). For example, as shown in FIG. 12, the cable (100') may be bent or folded vertically around a vertical axis so that a bending portion (103) is formed between the two ends of the cable (100') where a fixed portion (120) is provided.

[0146] Referring to FIG. 12, a cable tray (200-2) according to one embodiment may include a tray body (210) and one or more fixing protrusions (220-2).

[0147] According to one embodiment, the fixed protrusions (220-2) may be provided as a pair. The pair of fixed protrusions (220a-2, 220b-2) may be spaced apart from each other. The pair of fixed protrusions (220a-2, 220b-2) may be spaced apart from each other. For example, the fixed protrusions (220a-2, 220b-2) may have different rotational directions due to the bending part (103), and the fixed protrusions (220a-2, 220b-2) may be spaced apart from the bending part (103) in their respective directions that intersect each other.

[0148] According to one embodiment, the cable (100') can be fixed on the cable tray (200-2) by inserting the fixing projections (220a-2, 220b-2) of the cable tray (200-2) corresponding to the fixing groove (1221) of the fixing part (120). In this way, even in the case of a bent or folded cable (100'), the ends of the cable (100') are fixed by the fixing projections (220a-2, 220b-2) of the cable tray (200-2), thereby preventing the phenomenon of tilting caused by the thickness of the bending part (103) that may occur when stacking multiple cables (100').

[0149] FIG. 13 is a plan view showing a plurality of cables loaded in a cable tray according to one embodiment of the present disclosure.

[0150] The embodiment of FIG. 13 can be optionally combined with the embodiments of FIG. 1 to FIG. 12.

[0152] Referring to FIG. 13, a cable tray (200-3) according to one embodiment may include a tray body (210), one or more fixed protrusions (220-2) and guide ribs (e.g., a first guide rib (211) and a second guide rib (212)).

[0153] According to one embodiment, the fixed protrusions (220-2) may be provided as a pair. The pair of fixed protrusions (220a-2, 220b-2) may be spaced apart from each other. The pair of fixed protrusions (220a-2, 220b-2) may be offset from each other.

[0154] According to one embodiment, guide ribs (e.g., a first guide rib (211) and a second guide rib (212)) may be arranged to surround at least partially the bending portion (103) of the cable (100'). Guide ribs (e.g., a first guide rib (211) and a second guide rib (212)) may extend outward from one side of the tray body (210). The guide ribs may include a first guide rib (211) arranged to surround one side (e.g., the outer side) of the bending portion (103) of the cable (100') and a second guide rib (212) arranged to surround the other side (e.g., the inner side) of the bending portion (103) of the cable (100').
