　図１は、表示装置の外観斜視図である。以下の説明では、各図中に矢印で示す前、後、左、右、上および下のそれぞれの向きを使用する。表示装置１０は、略長方形板状の表示部１１と、表示部１１の下縁の両端部に取り付けられたスタンド金具２０，２０とを備える。表示部１１は、長方形の平板状の表示パネル１２を有する。表示パネル１２の上および左右の縁は、表示部１１の外装部材である側面筐体１３で覆われている。 FIG. 1 is an external perspective view of a display device. In the following description, the front, back, left, right, top, and bottom orientations indicated by arrows in each figure are used. The display device 10 includes a substantially rectangular plate-shaped display unit 11 and stand brackets 20 and 20 attached to both ends of the lower edge of the display unit 11. The display unit 11 includes a rectangular flat display panel 12.

　図２は、表示装置１０の側面図である。スタンド金具２０は、表示部１１の下縁から前方および後方に延在している。すなわち、表示装置１０は、側面視で表示部１１とスタンド金具２０とが逆Ｔ字形をなしている。 FIG. 2 is a side view of the display device 10. The stand metal fitting 20 extends forward and backward from the lower edge of the display unit 11. That is, in the display device 10, the display unit 11 and the stand bracket 20 are in an inverted T shape in a side view.
　図３は表示装置１０の縦断面図、図４は図３の部分拡大図である。図３および図４を使用して、表示装置１０の主要部の概要について説明する。表示部１１は、表示パネル１２および側面筐体１３に加えて、導光板１４、放熱板３１および後面筐体１６を有する。 3 is a longitudinal sectional view of the display device 10, and FIG. 4 is a partially enlarged view of FIG. An outline of a main part of the display device 10 will be described with reference to FIGS. 3 and 4. The display unit 11 includes a light guide plate 14, a heat radiating plate 31, and a rear housing 16 in addition to the display panel 12 and the side housing 13.
　導光板１４は、たとえば透明度が高い矩形のアクリル板である。導光板１４の広面は、表示パネル１２の広面と略同一形状である。導光板１４の表示パネル１２側の広面には、光学シートが設けられている。導光板１４の表示パネル１２とは反対側の広面には、反射シートが設けられている。 The light guide plate 14 is, for example, a rectangular acrylic plate with high transparency. The wide surface of the light guide plate 14 has substantially the same shape as the wide surface of the display panel 12. An optical sheet is provided on the wide surface of the light guide plate 14 on the display panel 12 side. A reflection sheet is provided on the wide surface of the light guide plate 14 opposite to the display panel 12.
　放熱板３１は、それぞれが略長方形板状である後板部３２、第１底板部３３、第２底板部３４および保持部３５を有する。後板部３２は、導光板１４の下部を後側から覆う。第１底板部３３は、後板部３２の下辺から前向きに突出する。第２底板部３４は、後板部３２の下辺から後向きに突出する。すなわち、後板部３２、第１底板部３３および第２底板部３４は、図３および図４に示すように略逆Ｔ字形を形成している。スタンド金具２０の前後方向の長さは、第１底板部３３および第２底板部３４の突出長さの合計よりも大きく、スタンド金具２０は、第１底板部３３および第２底板部３４に比べて、表示部１１から遠位まで延在している。 The heat radiating plate 31 includes a rear plate portion 32, a first bottom plate portion 33, a second bottom plate portion 34, and a holding portion 35, each of which has a substantially rectangular plate shape. The rear plate portion 32 covers the lower portion of the light guide plate 14 from the rear side. The first bottom plate portion 33 projects forward from the lower side of the rear plate portion 32. The second bottom plate portion 34 projects rearward from the lower side of the rear plate portion 32. That is, the rear plate portion 32, the first bottom plate portion 33, and the second bottom plate portion 34 form a substantially inverted T shape as shown in FIGS. The length of the stand bracket 20 in the front-rear direction is larger than the total protruding length of the first bottom plate portion 33 and the second bottom plate portion 34, and the stand bracket 20 is compared with the first bottom plate portion 33 and the second bottom plate portion 34. Thus, it extends from the display unit 11 to the distal end.
　第１底板部３３およびスタンド金具２０は重ねられており、下側から第１ねじ６１と第２ねじ６２とにより前後方向の２箇所で固定されている。第２底板部３４およびスタンド金具２０は重ねられており、下側から第３ねじ６３と第４ねじ６４とにより前後方向の２箇所で固定されている。 1st baseplate part 33 and stand metal fitting 20 are piled up, and are fixed at two places of the front-back direction with the 1st screw 61 and the 2nd screw 62 from the lower side. The 2nd bottom plate part 34 and the stand metal fitting 20 are piled up, and are being fixed by the 3rd screw 63 and the 4th screw 64 at two places of the front-back direction from the lower side.
　保持部３５は、第１底板部３３の少し上側で、後板部３２から前向きに、第１底板部３３に比べて短く突出する。後板部３２、第１底板部３３、第２底板部３４および保持部３５の長辺の長さは、表示部１１の下辺の長さと略同一である。保持部３５は、第１底板部３３と平行である。すなわち、第１底板部３３、保持部３５および後板部３２は、図４に示すように略逆Ｆ字形を形成している。 The holding part 35 projects slightly shorter than the first bottom plate part 33 in the forward direction from the rear plate part 32 slightly above the first bottom plate part 33. The lengths of the long sides of the rear plate portion 32, the first bottom plate portion 33, the second bottom plate portion 34, and the holding portion 35 are substantially the same as the length of the lower side of the display unit 11. The holding part 35 is parallel to the first bottom plate part 33. That is, the first bottom plate portion 33, the holding portion 35, and the rear plate portion 32 form a substantially inverted F shape as shown in FIG.
　保持部３５の上面には、導光板１４の下側の端面に対向するように照明基板１５が固定されている。照明基板１５は、導光板１４の長辺と略同一長さの長板形状の回路基板である。照明基板１５の導光板１４に対向する面には、複数の白色ＬＥＤ８０が実装されている。 The illumination board 15 is fixed to the upper surface of the holding part 35 so as to face the lower end face of the light guide plate 14. The illumination board 15 is a long board-shaped circuit board having substantially the same length as the long side of the light guide plate 14. A plurality of white LEDs 80 are mounted on the surface of the illumination substrate 15 facing the light guide plate 14.
　第１底板部３３とは別に保持部３５を設けてあるため、第１ねじ６１等で固定した部分の影響が保持部３５に伝わりにくく、保持部３５は、力を加えた場合であっても平らな状態である。よって、照明基板１５が波打つように変形することによる断線等の破損、照明基板１５と導光板１４の端面とが接触することによる傷、破損および変形を防止できる。また、変形等により照明基板１５と導光板１４との位置関係がずれた場合における輝度ムラ等による画質の低下は生じない。 Since the holding portion 35 is provided separately from the first bottom plate portion 33, the influence of the portion fixed by the first screw 61 or the like is not easily transmitted to the holding portion 35, and the holding portion 35 is a case where force is applied. It is in a flat state. Therefore, it is possible to prevent breakage such as disconnection due to deformation of the illumination board 15 so as to wave, and damage, breakage, and deformation due to contact between the illumination board 15 and the end face of the light guide plate 14. In addition, when the positional relationship between the illumination substrate 15 and the light guide plate 14 is shifted due to deformation or the like, image quality deterioration due to luminance unevenness or the like does not occur.
　後面筐体１６は、表示部１１の後面を覆う外装部材である。後面筐体１６は、表示パネル１２と略同一形状の長方形板状である。 The rear housing 16 is an exterior member that covers the rear surface of the display unit 11. The rear housing 16 has a rectangular plate shape that is substantially the same shape as the display panel 12.
　側面筐体１３は、下側が開口する略Ｕ字形の枠体であり、内向きに突出する前側縁１３１および後側縁１３２を有する。後側縁１３２は、前側縁１３１よりも短い。前側縁１３１は表示パネル１２および導光板１４に当接する。後側縁１３２は、後面筐体１６に当接する。側面筐体１３は、図３に示されるように前側縁１３１と後側縁１３２とが一端で接続された略Ｕ字状断面の金属棒を折り曲げて製作されている。 The side housing 13 is a substantially U-shaped frame that opens on the lower side, and has a front side edge 131 and a rear side edge 132 that protrude inward. The rear edge 132 is shorter than the front edge 131. The front edge 131 contacts the display panel 12 and the light guide plate 14. The rear edge 132 abuts on the rear housing 16. As shown in FIG. 3, the side housing 13 is manufactured by bending a metal bar having a substantially U-shaped cross section in which a front edge 131 and a rear edge 132 are connected at one end.
　後板部３２、第１底板部３３、前側筐体２１および上側筐体２６で構成された筐体部２８内には、第１基板台４１および第２基板台４６が収容されている。上側筐体２６は、外装部品である化粧板２５により覆われている。 A first substrate base 41 and a second substrate base 46 are accommodated in a housing portion 28 constituted by the rear plate portion 32, the first bottom plate portion 33, the front housing 21 and the upper housing 26. The upper casing 26 is covered with a decorative board 25 that is an exterior component.
　第２基板台４６の上には、制御基板２４に加えて、図示しないスピーカ、入力基板および配線部材等が配置されている。入力基板は、外部からの映像信号の入力を受け付けて、所定の信号処理を行う基板である。制御基板２４は、入力基板から出力された信号を受け付けて、ドライバ制御基板１９を制御する信号を出力する基板である。第２基板台４６には、伝熱部４９が表示パネル１２の下辺の下側近傍に位置するように固定されている。伝熱部４９は、左右方向に長い長方形板の後側の長辺から斜め上後方に立ち上がる。第２基板台４６は、アルミニウム合金または銅合金等の金属板からなり、熱伝導性が高い。 On the second board base 46, in addition to the control board 24, a speaker, an input board, a wiring member and the like (not shown) are arranged. The input board is a board that receives a video signal input from the outside and performs predetermined signal processing. The control board 24 is a board that receives a signal output from the input board and outputs a signal for controlling the driver control board 19. A heat transfer section 49 is fixed to the second substrate base 46 so as to be positioned near the lower side of the lower side of the display panel 12. The heat transfer section 49 rises obliquely upward and rearward from the long side on the rear side of the rectangular plate that is long in the left-right direction. The second substrate base 46 is made of a metal plate such as an aluminum alloy or a copper alloy, and has high thermal conductivity.
　図３に示すように、第１基板台４１は、放熱板３１の第１底板部３３の上部に固定されている。第１基板台４１の上には、表示パネル１２の下辺に沿って外向きに接続されたドライバ基板１７が載置されている。 As shown in FIG. 3, the first substrate base 41 is fixed to the upper portion of the first bottom plate portion 33 of the heat radiating plate 31. On the first substrate base 41, the driver substrate 17 connected outward is placed along the lower side of the display panel 12.
　ドライバ基板１７は、表示パネル１２に接続された軟性基板の一例である。ドライバ基板１７は長方形であり、一方の長辺が表示パネル１２に接続されている。ドライバ基板１７の他方の長辺には、ドライバ制御基板１９が接続されている。ドライバ制御基板１９は、表示パネル１２の長辺の約半分の長さの長辺を有する長方形の基板である。ドライバ基板１７には、例えばポリイミド製シートと金属製の配線パターンとを積層したＦＰＣ（Flexible printed circuit）を使用する。 The driver substrate 17 is an example of a flexible substrate connected to the display panel 12. The driver board 17 is rectangular, and one long side is connected to the display panel 12. A driver control board 19 is connected to the other long side of the driver board 17. The driver control board 19 is a rectangular board having a long side that is approximately half the long side of the display panel 12. For the driver substrate 17, for example, an FPC (Flexible printed circuit) in which a polyimide sheet and a metal wiring pattern are stacked is used.
　ドライバ基板１７の後面には、ドライバ１８が実装されている。ドライバ１８は、表示パネル１２の表示面よりも前側に配置されている。ドライバ１８は、ドライバ制御基板１９から入力された信号に基づいて表示パネル１２の各画素を駆動する駆動信号を出力する集積回路である。ドライバ基板１７は、ドライバ１８が実装された部分の裏側で、伝熱部４９に接触する。 A driver 18 is mounted on the rear surface of the driver board 17. The driver 18 is disposed in front of the display surface of the display panel 12. The driver 18 is an integrated circuit that outputs a drive signal for driving each pixel of the display panel 12 based on a signal input from the driver control board 19. The driver board 17 contacts the heat transfer section 49 on the back side of the part where the driver 18 is mounted.
　図５は、放熱板３１の斜視図であり、図６は、放熱板３１の拡大斜視図である。第１底板部３３は、第１孔７１および第１孔７１の前側に配置された第２孔７２を備える。第１孔７１および第２孔７２の内面には雌ねじが設けられている。第１孔７１には、前述した第１ねじ６１が挿入され、第２孔７２には、前述した第２ねじ６２が挿入される。 FIG. 5 is a perspective view of the heat radiating plate 31, and FIG. 6 is an enlarged perspective view of the heat radiating plate 31. The first bottom plate portion 33 includes a first hole 71 and a second hole 72 disposed on the front side of the first hole 71. Female threads are provided on the inner surfaces of the first hole 71 and the second hole 72. The aforementioned first screw 61 is inserted into the first hole 71, and the aforementioned second screw 62 is inserted into the second hole 72.
　第２底板部３４は、第３孔７３および第３孔７３の後側に配置された第４孔７４を備える。第３孔７３および第４孔７４の内面には雌ねじが設けられている。第３孔７３には、前述した第３ねじ６３が挿入され、第４孔７４には、前述した第４ねじ６４が挿入される。 The second bottom plate portion 34 includes a third hole 73 and a fourth hole 74 disposed on the rear side of the third hole 73. Female threads are provided on the inner surfaces of the third hole 73 and the fourth hole 74. The aforementioned third screw 63 is inserted into the third hole 73, and the aforementioned fourth screw 64 is inserted into the fourth hole 74.
　放熱板３１は、後板部３２の左右それぞれの短辺に沿って前方に突出する長方形板状の側板部３６を有する。側板部３６には略等間隔に５個の第５孔７５が設けられている。第５孔７５の内面には、雌ねじが設けられている。なお、第５孔７５の数は、図６に示す５個に限定しない。表示装置１０の寸法等に応じて、任意の数の第５孔７５を設けることができる。 The heat sink 31 has a rectangular plate-like side plate portion 36 that protrudes forward along the short sides of the left and right sides of the rear plate portion 32. The side plate portion 36 is provided with five fifth holes 75 at substantially equal intervals. An internal thread is provided on the inner surface of the fifth hole 75. The number of the fifth holes 75 is not limited to five shown in FIG. An arbitrary number of fifth holes 75 can be provided according to the dimensions of the display device 10 and the like.
　後板部３２は、保持部３５の上側に接する部分に、他の部分よりも肉厚になった厚肉部３７を有する。このように後板部３２が、保持部３５の上側に接する部分に厚肉部３７を有するため、この部分では変形を生じにくい。そのため、外力による変形は、主に保持部３５と第１底板部３３との間の部分で発生し、表示部１１内の部品間の位置ずれ等は生じにくい。 The rear plate part 32 has a thick part 37 that is thicker than the other parts at the part in contact with the upper side of the holding part 35. As described above, since the rear plate portion 32 has the thick portion 37 in the portion in contact with the upper side of the holding portion 35, the portion hardly deforms. For this reason, deformation due to external force mainly occurs in a portion between the holding portion 35 and the first bottom plate portion 33, and misalignment between components in the display portion 11 hardly occurs.
　なお、放熱板３１は、Ｔ字形断面を有するアルミニウム合金または銅合金等の高熱伝導性金属の押出成形品を切断し、端部を折り曲げて側板部３６を形成することにより製作される。 The heat radiating plate 31 is manufactured by cutting an extruded product of a highly heat conductive metal such as an aluminum alloy or a copper alloy having a T-shaped cross section and bending the end portion to form the side plate portion 36.
　図７は、側面筐体１３と放熱板３１とを組み合わせた状態を示す模式図である。側面筐体１３の後側縁１３２は、側面筐体１３の下部においては除去されており、その部分に放熱板３１がはめ込まれて、長方形の枠体を形成する。側面筐体１３の下端部においては、前側縁１３１も除去されている。 FIG. 7 is a schematic diagram showing a state in which the side housing 13 and the heat radiating plate 31 are combined. The rear edge 132 of the side housing 13 is removed at the lower portion of the side housing 13, and the heat radiating plate 31 is fitted into that portion to form a rectangular frame. The front side edge 131 is also removed at the lower end of the side housing 13.
　側面筐体１３の内面と放熱板３１の側板部３６の外面とが接触する。側面筐体１３と側板部３６とは、側面筐体１３の外側から第５孔７５に挿入された皿ねじにより固定される。以上のように、側面筐体１３と放熱板３１とが面で接触した状態で固定されることにより、外力を受けても歪みにくい、構造部材の枠体が構成される。 The inner surface of the side housing 13 and the outer surface of the side plate portion 36 of the heat sink 31 are in contact with each other. The side housing 13 and the side plate portion 36 are fixed by a countersunk screw inserted into the fifth hole 75 from the outside of the side housing 13. As described above, by fixing the side housing 13 and the heat radiating plate 31 in contact with each other, a frame of a structural member that is not easily distorted even when subjected to an external force is configured.
　以下、表示装置１０の動作の概要を説明する。照明基板１５に搭載された白色ＬＥＤ８０からの出射光は、導光板１４の下面に入射する。入射した光は、導光板１４の作用により、平面光になって導光板１４の前側の広面から放射される。放射された平面光は、表示パネル１２の背面から前側に透過する。すなわち導光板１４と照明基板１５とは、表示パネル１２を背面から照明するバックライトを構成している。 Hereinafter, an outline of the operation of the display device 10 will be described. Light emitted from the white LED 80 mounted on the illumination board 15 enters the lower surface of the light guide plate 14. The incident light is radiated from the wide surface on the front side of the light guide plate 14 as planar light by the action of the light guide plate 14. The emitted planar light is transmitted from the back surface of the display panel 12 to the front side. That is, the light guide plate 14 and the illumination substrate 15 constitute a backlight that illuminates the display panel 12 from the back.
　照明基板１５は、表示パネル１２の後側を照明する本実施の形態の照明部の一例である。照明基板１５には、白色ＬＥＤの代わりに有機ＥＬ（ElectroLuminescence）素子等の発光体が実装されていても良い。照明部は、冷陰極管等の発光体であっても良い。 The illumination board 15 is an example of the illumination unit of the present embodiment that illuminates the rear side of the display panel 12. A light emitter such as an organic EL (ElectroLuminescence) element may be mounted on the illumination board 15 instead of the white LED. The illumination unit may be a light emitter such as a cold cathode tube.
　なお、導光板１４と照明基板１５とを組み合わせた、エッジライト方式のバックライトの代わりに、表示パネル１２の後側に多数の白色ＬＥＤと拡散シート等を配置したいわゆる直下型のバックライトを使用しても良い。 In addition, instead of the edge light type backlight combining the light guide plate 14 and the illumination substrate 15, a so-called direct type backlight in which a large number of white LEDs and a diffusion sheet are arranged on the rear side of the display panel 12 is used. You may do it.
　入力基板から入力された映像信号に基づいて、制御基板２４がドライバ制御基板１９を制御する信号を接続する。ドライバ制御基板１９の制御に基づいて、ドライバ１８が表示パネル１２を構成する各画素を制御する。これにより、表示パネル１２を構成する各画素がバックライトから放射された光を透過および遮蔽する。バックライトの作用により、ユーザは表示パネル１２に表示される映像を視認することができる。 The control board 24 connects a signal for controlling the driver control board 19 based on the video signal input from the input board. Based on the control of the driver control board 19, the driver 18 controls each pixel constituting the display panel 12. Thereby, each pixel which comprises the display panel 12 permeate | transmits and shields the light radiated | emitted from the backlight. The user can visually recognize the video displayed on the display panel 12 by the action of the backlight.
　なお、入力基板および制御基板２４の機能の一部または全部を、表示装置１０の外部に設けた機器が実行しても良い。 Note that a part or all of the functions of the input board and the control board 24 may be executed by a device provided outside the display device 10.
　表示装置１０の放熱について説明する。表示装置１０を構成する部品のうち、照明基板１５およびドライバ１８は特に発熱量が多い部品である。照明基板１５から発生した熱は、放熱板３１を介して、後面筐体１６、側面筐体１３および上側筐体２６を経て周囲の床、壁、空中等に拡散する。また、ドライバ１８から発生した熱は、ドライバ基板１７を介して伝熱部４９に伝達され、伝達された熱は、放熱板３１を介して、後面筐体１６、側面筐体１３および上側筐体２６を経て周囲の床、壁、空中等に拡散する。 The heat dissipation of the display device 10 will be described. Among the components constituting the display device 10, the illumination board 15 and the driver 18 are components that generate a large amount of heat. The heat generated from the illumination board 15 is diffused through the heat radiating plate 31 to the surrounding floor, wall, air, etc. via the rear casing 16, the side casing 13 and the upper casing 26. Further, the heat generated from the driver 18 is transmitted to the heat transfer section 49 through the driver board 17, and the transmitted heat is transmitted through the heat radiating plate 31 to the rear housing 16, the side housing 13, and the upper housing. It diffuses to the surrounding floor, wall, air etc. via 26.
　本実施の形態によると、表示パネル１２の前方に突出した第１底板部３３と表示パネル１２の後方に突出した第２底板部３４とを有する逆Ｔ字形の放熱板３１を備えて、第１底板部３３および第２底板部３４をスタンド金具２０にねじ留めにて固定する構造としたので、表示部１１の後面を完全に平坦にできると共に、高い強度を維持することができる。よって、デッドスペースを発生させず、部屋の空間を有効に活用できる表示装置１０を提供することができる。 According to the present embodiment, the first T-shaped heat sink 31 having the first bottom plate portion 33 protruding forward of the display panel 12 and the second bottom plate portion 34 protruding rearward of the display panel 12 is provided. Since the bottom plate portion 33 and the second bottom plate portion 34 are fixed to the stand metal fitting 20 by screwing, the rear surface of the display unit 11 can be completely flattened and high strength can be maintained. Accordingly, it is possible to provide the display device 10 that can effectively use the room space without generating a dead space.
　本実施の形態によると、スタンド金具２０，２０間の空間をユーザが自由に使うことができる。 According to this embodiment, the user can freely use the space between the stand brackets 20 and 20.
　本実施の形態によると、側面筐体１３と放熱板３１とが面で接触した状態で固定された歪みにくい枠体が構成されるため、外力を受けた場合であっても表示パネル１２、導光板１４および後面筐体１６等の薄い部材が変形または破壊することを防ぐことができる。また、放熱板３１が構造部材を兼ねることにより、少ない部品数で表示装置１０を構成することができる。 According to the present embodiment, since the frame body which is fixed in a state where the side housing 13 and the heat radiating plate 31 are in contact with each other is configured, the display panel 12 and the conductive plate are guided even when receiving external force. Thin members such as the optical plate 14 and the rear housing 16 can be prevented from being deformed or broken. Further, since the heat radiating plate 31 also serves as a structural member, the display device 10 can be configured with a small number of components.
　本実施の形態によると、スタンド金具２０に固定される第１底板部３３および第２底板部３４とは別に保持部３５を設けてあるため、外力を受けた場合であっても照明基板１５の波打つような変形による破損および画質の低下が生じにくい表示装置１０を提供することができる。 According to the present embodiment, since the holding portion 35 is provided separately from the first bottom plate portion 33 and the second bottom plate portion 34 that are fixed to the stand metal fitting 20, It is possible to provide the display device 10 that is less prone to breakage and image quality deterioration due to undulating deformation.
　本実施の形態によると、照明基板１５およびドライバ１８が発生する熱を効率良く放熱できる表示装置１０を提供することができる。これにより、熱による各部品の損傷、劣化、誤作動等を防止することができる。 According to the present embodiment, it is possible to provide the display device 10 that can efficiently dissipate the heat generated by the illumination board 15 and the driver 18. Thereby, damage, deterioration, malfunction, etc. of each component by heat can be prevented.
　表示装置１０をテレビジョン受信機として使用する場合には、入力基板にテレビジョン放送のアンテナを接続するアンテナ端子およびテレビジョン放送の電波を受信するチューナ回路を備えたテレビジョン受信部を搭載する。テレビジョン受信部が受信した放送信号に所定の処理を行い、映像信号と音声信号とに分離する。映像信号に基づき表示パネル１２に映像を表示する。音声信号はスピーカから出力する。 When the display device 10 is used as a television receiver, a television receiver including an antenna terminal for connecting a television broadcast antenna and a tuner circuit for receiving television broadcast radio waves is mounted on the input board. A predetermined process is performed on the broadcast signal received by the television receiver, and the broadcast signal is separated into a video signal and an audio signal.
