[0073] As shown in Figures 11 and 7, the first parts 122a of the outer beams 122a, 122b, 122c, and 122d can intersect with the third parts 122c of the outer beams 122a, 122b, 122c, and 122d. For example, the cross section of the first parts 122a of the outer beams 122a, 122b, 122c, and 122d can be generally H-shaped, and the cross section of the third parts 122c can be generally H-shaped. This can improve the corner rigidity of the frame 12.

[0074] The first parts 122a of the outer beams 122a, 122b, 122c, and 122d can intersect with the second parts 122b of the outer beams 122a, 122b, 122c, and 122d. For example, the cross section of the first parts 122a of the outer beams 122a, 122b, 122c, and 122d can be generally H-shaped, and the cross section of the second parts 122b can be generally H-shaped. This can improve the corner rigidity of the frame 12.

[0075] The fourth part 122d of the outer beams 122a, 122b, 122c, and 122d may intersect with the third part 122c of the outer beams 122a, 122b, 122c, and 122d. For example, the cross section of the fourth part 122d of the outer beams 122a, 122b, 122c, and 122d may be generally H-shaped, and the cross section of the third part 122c may be generally H-shaped. This may improve the corner rigidity of the frame 12.

[0076] The fourth parts 122d of the outer beams 122a, 122b, 122c, and 122d may intersect with the second parts 122b of the outer beams 122a, 122b, 122c, and 122d. For example, the cross section of the fourth parts 122d of the outer beams 122a, 122b, 122c, and 122d may be generally H-shaped, and the cross section of the second parts 122b may be generally H-shaped. This may improve the corner rigidity of the frame 12.

[0077] As shown in FIG. 12, the housing 150 may include a lower case 151 and an upper cover 154. The lower case 151 may be tub-shaped to provide an internal storage space. For example, the lower case 151 may be an injection molded product made of a flame-retardant material. The lower case 151 may be made of a material with enhanced chemical resistance. The lower case 151 may have an opening for weight reduction. The lower plate 152 may be located at the bottom of the lower case 151. The lower plate 152 may include metal. The lower plate 152 may cover the opening of the lower case 151.

[0078] At least one electrical element 16M may be mounted on the substrate 16. For example, the substrate 16 may be a power supply unit PSU or a main board. The substrate 16 may be located on a lower plate 152.

[0079] The upper plate 153 may be located on the substrate 16. The upper plate 153 may include a metal. The upper plate 153 may face the lower plate 152.

[0080] The upper cover 154 can cover the upper plate 153 and close the lower case 151. The upper cover 154 can include a metal. For example, the upper cover 154 can be aluminum. The upper cover 154 can be combined with the lower case 151.

[0081] This can improve the chemical resistance of the substrate 16 on which the electric element 16M is mounted.

[0082] 13 and 14, the housing 150 may include a docking opening 151d. The docking opening 151d may be formed on a side of the housing 150. A recessed sidewall 151b may be formed around the docking opening 151d. The recessed sidewall 151b may be recessed from an outer sidewall 151a of the housing 150 to form a step inward.

[0083] The connectors 16M1 and 16M2 mounted on the board 16 may be exposed to the outside through the docking opening 151d. The undercover 151c may be formed below the docking opening 151d. The undercover 151c may support the connectors 16M1 and 16M2 exposed to the docking opening 151d and / or the board 16 below the connectors 16M1 and 16M2. The undercover 151c may protrude from the recessed sidewall 151b. An outer surface of the undercover 151c may correspond to an outer surface of the outer sidewall 151a.

[0084] Gaps G1, G2 may be formed between the connectors 16M1, 16M2 and the docking opening 151d. The gaps G1, G2 may include a first gap G1 and a second gap G2. The first gap G1 may be formed between the connectors 16M1, 16M2 and the left inner surface or the right inner surface of the docking opening 151d. The second gap G2 may be formed between the connectors 16M1, 16M2 and the upper inner surface of the docking opening 151d.

[0085] This not only improves the chemical resistance but also protects the main components from external impact.

[0086] 15 and 16, the control boards 70a, 70b, and 70c may be mounted or fixed to the rear surface of a frame 75 of a display 70. For example, the control boards 70a, 70b, and 70c may be a power board 70a, a sub-board 70b, or a source PCB 70c. Electronic elements may be mounted on the control boards 70a, 70b, and 70c, and heat may be generated while the electronic elements are operating.

[0087] A flexible cable CA may electrically connect the power board 70a and the display panel 71. The power board 70a may adjust power and / or signals provided to a light source of the display 70. The power board 70a may be referred to as a light source drive board 70a. The sub-board 70a may process image information provided to the display panel 71 (see FIG. 1). The source PCB 70c may be mounted or fixed to the rear surface of the frame 75 adjacent to the lower side of the frame 75. A COF (70CA) may electrically connect the source PCB 70c and the display panel 71.

[0088] The shielding member 77 may cover the control boards 70a, 70b, and 70c. The shielding member 77 may be referred to as a first shielding member 77, a display shielding member 77, a heat dissipation sheet 77, or a heat dispersion sheet 77. For example, the shielding member 77 may be a graphite sheet. The shielding member 77 may cover the power board 70a. The shielding member 77 may overlap at least a portion of the power board 70a.

[0089] As shown in Figures 17 and 18, a housing 150 incorporating a power supply unit 16 (see Figure 6) may be mounted or coupled on the frame 12 of the base 10. A main board 19a may be mounted or coupled on the frame 12 of the base 10 adjacent to the housing 150 of the power supply unit 16. The power supply unit 16 may supply necessary power to the display device 1 (see Figure 1). The main board 19a may process image information displayed via the display panel 71 and / or audio information provided via the speaker assembly. The power supply unit 16 and / or the main board 19a may generate heat when operating.

[0090] The shield plate 19b covers a part of the main board 19a and can be mounted or fixed on the frame 12. The shield plate 19b can prevent physical and electrical damage to the main board 19a.

[0091] The shielding member 18 can cover the main board 19a. The shielding member 18 can be called a second shielding member 18, a base shielding member 18, a heat dissipation sheet 18, or a heat dissipation sheet 18. The shielding member 18 can overlap all or at least a portion of the main board 19a. For example, the shielding member 18 can be a graphite sheet.

[0092] 19 and 20, the cover 20 can be opened and closed from the base 10 around the hinge 30 (see FIG. 1) and the display 70 can be stored inside the base 10. The display 70 can be moved to the outside of the base 10 by the arm 50 or stored on the base 10. When the display 70 is stored in the base 10, the display 70 and the base 10 can be arranged in parallel and face each other.

[0093] The side cover 72 covers the sides of the display panel 71, and the back cover 76 is located behind the display panel 71 and may be combined with the side cover 72. The control board 70a may be located between the display panel 71 and the back cover 76. For example, the control board 70a may be a light source drive board 70a, and high heat may be generated when the control board 70a is driven. The heat generated from the control board 70a may be released to the outside through the back cover 76.

[0094] The main board 19a mounted on the frame 12 of the base 10 may be located between the frame 12 and the top 13. When the main board 19a is operated, a large amount of heat may be generated, and the heat may be dissipated to the outside through the top 13.

[0095] The first shielding member 77 may be located between the control board 90a and the back cover 76. The first shielding member 77 may be fixed or glued to the back cover 76. For example, the first shielding member 77 may be a graphite sheet. The second shielding member 18 may be located between the main board 19a and the top 13.

[0096] 15 and 17, FIG. 15 shows the rear side of the display 70 facing the base 10, and FIG. 17 shows the front side of the base 10 facing the display 70.

[0097] The housing 150 incorporating the power supply unit 16 (see FIG. 6) can generate high heat. The light source drive board 70a can generate high heat. When the display 70 is housed in the base 10, the housing 150 incorporating the power supply unit 16 can not overlap with the light source drive board 70a. This allows the heat generated from the housing 150 and the light source drive board 70a to be evenly distributed within the display device 1.

[0098] When the display 70 is housed in the base 10, the light source drive board 70a may at least partially overlap the main board 19a. Heat generated from the light source drive board 70a and the main board 19a may be dissipated toward each other and accumulated.

[0099] Heat generated from the light source drive board 70a may be horizontally dispersed and dissipated by the first shielding member 77. Heat generated from the main board 19a may be horizontally dispersed and dissipated by the second shielding member 18. For example, the first shielding member 77 may overlap the second shielding member 18 partially or at least partially. As another example, the first shielding member 77 may be aligned so as not to overlap with the second shielding member 18. As another example, the first shielding member 77 may be adjacent to the second shielding member 18, forming a boundary therewith. This allows the heat generated from the main board 19a and the heat generated from the light source drive board 70a to be dispersed without being accumulated.

[0100] As a result, even when the display 70 is housed in the base 10, heat generated by driving the display 70 can be evenly dispersed and dissipated.

[0101] As shown in FIG. 21, the second shielding member 18 can include a first sheet part 18a, a second sheet part 18b, and a third sheet part 18c.

[0102] The first sheet part 18a is located between the main board 19a and the light source drive board 70a and can cover the main board 19a. The second sheet part 18b can extend from the first sheet part 18a. The second sheet part 18b can form a slope that is lower than the first sheet part 18a.

[0103] The second sheet part 18b can extend from the first sheet part 18a while being curved toward the bottom of the frame 12 of the base 10. The third sheet part 18c can be located above the bottom of the frame 12 of the base 10 and cover the bottom of the frame 12.

[0104] The first sheet part 18a may have a negative inclination towards the second sheet part 18b. The inclination of the first sheet part 18a may be less than the inclination of the second sheet part 18b.

[0105] As a result, moisture that may form on the second shielding member 18 covering the main board 19a when the main board 19a is turned on and off can be discharged while passing through the first sheet part 18a, the second sheet part 18b, and the third sheet part 18c.

[0106] As shown in Figs. 22 to 24, a bumper 80 may include a body 81 and a wall 83. The body 81 may be a first piece 81 that extends widely and has a certain thickness.

The sealing rib 85b may be formed protruding from an outer surface of the insert 85. There may be a plurality of sealing ribs 85b, and the plurality of sealing ribs 85b may be formed parallel to each other and spaced apart.

[0110] As shown in Figs. 25 to 27, the bumper 80 may be coupled to the side cover 72 of the display 70 (see Fig. 1). The body 81 of the bumper 80 may be in contact with the rear surface of the frame 75 or may be supported by the rear surface of the frame 75. The wall 83 of the bumper 80 may be positioned on a cut-out part 72c of the side cover 72.

The guide panel 79 may include a locking portion 79a. The locking portion 79a may be formed by protruding from an outer surface of the guide panel 79 at a corner of the guide panel 79. The bumper 80 may be inserted into the cutout part 72c of the side cover 72, and a fixing rib 85a of the bumper 80 may be engaged with and fixed to the locking portion 79a of the guide panel 79.

[0113] As shown in Fig. 28 and Fig. 29, the optical layer 73 may be located between the frame 75 and the display panel 71. The guide panel 79 may be coupled to the frame 75 and support a rear surface adjacent to an edge of the display panel 71.

The inner top 72b may cover a front surface of the edge of the display panel 71 and be coupled to the guide panel 79 between the guide panel 72b and the side cover 72. The buffer layer BF may be fixed to the inside of the inner top 72b and face the front surface of the display panel 71. The buffer layer BF may form a gap with the front surface of the display panel 71.

[0114] The side cover 72 covers the front surface adjacent to the edge of the display panel 71, and may cover the side surfaces of the guide panel 79 and / or the inner top 72b. The body 81 of the bumper 80 is located between the frame 75 and the back cover 76, and the wall 83 of the bumper 80 may connect the side cover 72 and the back cover 76. The apron 83a of the bumper 80 may protrude from the outer surface of the side cover 72.

[0115] This makes it possible to protect the display 70 by absorbing shocks that may occur to the corners of the display 70 while the display 70 is housed in the base 10 (see FIG. 19).

[0116] 30, the cover 20 may include an outer cover 210, a middle frame 240, and an inner cover 250. The outer cover 210 may have an accommodating space inside in the shape of a tub. The middle frame 240 may be coupled to the inside of the outer cover 210, and the inner cover 250 may be coupled to the middle frame 240.
