[0077] The fourth parts 122d of the outer beams 122a, 122b, 122c, and 122d intersect with the third parts 122c 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 third parts 122c may be generally H-shaped. This can improve the corner rigidity of the frame 12.

[0078] The fourth parts 122d of the outer beams 122a, 122b, 122c, and 122d 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 can improve the corner rigidity of the frame 12.

[0079] Referring to FIG. 12, the housing 150 includes 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 to reduce weight. 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.

[0080] 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 the lower plate 152.

[0081] 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.

[0082] The upper cover 154 can cover the upper plate 153 and close the lower case 151. The upper cover 154 can include metal. For example, the upper cover 154 can be made of aluminum. The upper cover 154 can be combined with the lower case 151.

[0083] This improves the chemical resistance of the substrate 16 on which the electric element 16M is mounted.

[0084] 13 and 14, the housing 150 includes a docking opening 151d. The docking opening 151d is formed in a side surface of the housing 150. A recessed sidewall 151b is formed around the docking opening 151d. The recessed sidewall 151b may be recessed inward from the outer sidewall 151a of the housing 150 to form a step.

[0085] The connectors 16M1 and 16M2 mounted on the substrate 16 are exposed to the outside through the docking opening 151d. An undercover 151c may be formed below the docking opening 151d. The undercover 151c may support the connectors 16M1 and 16M2 exposed in the docking opening 151d and / or the substrate 16 below the connectors 16M1 and 16M2. The undercover 151c protrudes from the recessed sidewall 151b. The outer surface of the undercover 151c may correspond to the outer surface of the outer sidewall 151a.

[0086] Gaps G1 and G2 may be formed between the connectors 16M1 and 16M2 and the docking opening 151d. The gaps G1 and G2 include a first gap G1 and a second gap G2. The first gap G1 may be formed between the connectors 16M1 and 16M2 and the left or right inner surface of the docking opening 151d. The second gap G2 may be formed between the connectors 16M1 and 16M2 and the upper inner surface of the docking opening 151d.

[0087] This not only improves chemical resistance but also protects the main components from external impact.

[0088] 15 and 16, the control boards 70a, 70b, and 70c are attached or fixed to the rear surface of a frame 75 of the 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 are mounted on the control boards 70a, 70b, and 70c, and heat is generated as the electronic elements are driven.

[0089] A flexible cable CA can electrically connect the power board 70a and the display panel 71. The power board 70a can adjust the power and / or signals provided to the light source of the display 70. The power board 70a may also be referred to as a light source drive board 70a. The sub-board 70b processes image information provided to the display panel 71 (see FIG. 1). The source PCB 70c is attached or fixed to the back surface of the frame 75 adjacent to the lower edge of the frame 75. The COF 70CA can electrically connect the source PCB 70c and the display panel 71.

[0090] The shielding member 77 may cover the control boards 70a, 70b, and 70c. The shielding member 77 may also 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.

[0091] 17 and 18, a housing 150 incorporating a power supply unit 16 (see FIG. 6) may be mounted on or coupled to the frame 12 of the base 10. A main board 19a may be mounted on or coupled to the frame 12 of the base 10 adjacent to the housing 150 of the power supply unit 16. The power supply unit 16 supplies power necessary for the display device 1 (see FIG. 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.

[0092] The shield plate 19b covers a part of the main board 19a and is attached or fixed on the frame 12. The shield plate 19b can prevent physical and electrical damage to the main board 19a.

[0093] The shielding member 18 may cover the main board 19a. The shielding member 18 may also be referred to as a second shielding member 18, a base shielding member 18, a heat dissipation sheet 18, or a heat dispersion sheet 18. The shielding member 18 may overlap all or at least a portion of the main board 19a. For example, the shielding member 18 may be a graphite sheet.

[0094] 19 and 20, the cover 20 can be opened and closed from the base 10 around the hinge 30 (see FIG. 1) so that 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 are arranged side by side and face each other.

[0095] 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 can be combined with the side cover 72. The control board 70a is 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 operating. The heat generated from the control board 70a is dissipated to the outside through the back cover 76.

[0096] The main board 19a mounted on the frame 12 of the base 10 is located between the frame 12 and the top 13. When the main board 19a is operating, a large amount of heat is generated, and the heat is dissipated to the outside through the top 13.

[0097] The first shielding member 77 may be located between the control board 70a 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.

[0098] 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.

[0099] The housing 150 incorporating the power supply unit 16 (see FIG. 6 ) can generate high heat. The light source drive board 70a can also generate high heat. When the display 70 is housed in the base 10, the housing 150 incorporating the power supply unit 16 does 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 dispersed within the display device 1.

[0100] 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 is dissipated toward and accumulated with each other.

[0101] Heat generated from the light source drive board 70a is dispersed and dissipated in the horizontal direction by the first shielding member 77. Heat generated from the main board 19a is dispersed and dissipated in the horizontal direction by the second shielding member 18. For example, the first shielding member 77 partially or at least partially overlaps the second shielding member 18. 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 therebetween. This allows the heat generated from the main board 19a and the light source drive board 70a to be dispersed without accumulating.

[0102] As a result, even when the display 70 is housed in the base 10, the heat generated by driving the display 70 can be uniformly dispersed and dissipated.

[0103] Referring to FIG. 21, the second shielding member 18 may include a first sheet part 18a, a second sheet part 18b, and a third sheet part 18c.

[0104] 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 be inclined downward from the first sheet part 18a.

[0105] The second sheet part 18b may extend from the first sheet part 18a while curving toward the bottom of the frame 12 of the base 10. The third sheet part 18c may be positioned above the bottom of the frame 12 of the base 10 and cover the bottom of the frame 12.

[0106] The first sheet part 18a may have a negative slope toward the second sheet part 18b. The slope of the first sheet part 18a may be less than the slope of the second sheet part 18b.

[0107] This allows moisture formed on the second shielding member 18 covering the main board 19a depending on whether the main board 19a is turned on or off to be discharged while passing through the first sheet part 18a, the second sheet part 18b, and the third sheet part 18c.

[0108] 22 and 23, the shield plates 19b and 190 include a flat portion 191, a support groove 193, a coupling groove 192, a contact portion 194, and a drain path 195. For example, the shield plate 190 may include a metal and may be formed by pressing. One surface of the flat portion 191 may be coated with an insulating material.

There may be multiple coupling grooves 192.

[0111] The contact portion 194 may be recessed from the flat portion 191. The recessed direction of the contact portion 194 may be the same as the recessed direction of the support groove 193 and / or the coupling groove 192. The contact portion 194 may have an overall rectangular dome shape. The rear surface of the bottom of the contact portion 194 contacts an electronic component on the main board 19a. For example, the electronic component may be an integrated circuit semiconductor chip. Heat from the electronic component is transferred to the contact portion 194.

[0112] The drainage channels 195 include horizontal lines 195a, 195b, 195c, and 195d and vertical lines 195e, 195f, 195g, and 195h.

[0116] The second vertical line 195f includes a first part 195f1, a second part 195f2, and a third part 195f3. The first part 195f1 connects the support groove 193 and the contact portion 194. The second part 195f2 connects the contact portion 194 and the second horizontal line 195b. The third part 195f3 is located adjacent to the lower edge of the flat portion 191. The third part 195f3 connects the support groove 193 and the third horizontal line 195c.

[0117] The third vertical line 195g is located adjacent to the left edge of the flat plate portion 191 while passing through at least one support groove 193. The third vertical line 195g faces the first vertical line 195e with respect to the second vertical line 195f.

[0118] The fourth vertical line 195h is connected to the fourth horizontal line 195d and faces the third vertical line 195g across the coupling groove 192. The first vertical line 195e, the second vertical line 195f, and / or the third vertical line 195g are connected to the lower edge of the flat plate portion 191. This allows water vapor and / or water condensed or collected on the shield plates 19b and 190 to be discharged to the outside through the drainage channel 195.

[0119] The shield plate 190 is positioned on the main board 19a and can cover the main board 19a. The shield plate 190 is supported by a boss B or coupled to the main board 19a by a support clip SC. The boss B supports the outer surface of the support groove 193 or is inserted into the outer surface of the support groove 193. A boss insertion groove 193H may be formed on the outer surface of the support groove 193. The boss B may be press-fitted into the boss insertion groove 193H.

[0120] The support clips SC pass through holes 192a of the coupling grooves 192. The support clips SC can be inserted into the coupling grooves 192 to be coupled to the main board 19a. Clip holes 19aH can be formed through the main board 19a. The support clips SC can be engaged with the clip holes 19aH. The hooks HK of the support clips SC can prevent the support clips SC coupled to the clip holes 19aH from being separated.

[0121] 24, the shield plate 190 may be inclined relative to the main board 19a. The shield plate 190 and the main board 19a form a first distance H1 and a second distance H2. The first distance H1 is located close to a first horizontal line 195a, and the second distance H2 is located close to a third horizontal line 195c. The first distance H1 may be greater than the second distance H2.

[0122] The shielding member 180 includes a plurality of sheets 181 and 182. The shielding member 180 includes a first sheet 181 and a second sheet 182.
