Description

本発明は二つの挾持部材により表示パネルの周縁部を前後から挾持してある液晶テレビジョン等の表示装置に関する。   The present invention relates to a display device such as a liquid crystal television in which a peripheral portion of a display panel is held from front and rear by two holding members.

液晶テレビジョン等の薄型の表示装置は、前側に表示面を有し直方体をなす表示パネルと、該表示パネルの周縁部前面に対向する第１環板部及び該第１環板部の外縁から後方へ延出されている第１枠部を有する金属性の前挾持部材と、前記表示パネルの周縁部後面に対向する第２環板部及び該第２環板部の外縁から後方へ延出されている第２枠部を有し、前記第１枠部との間で前記表示パネルの周縁部を挾持してある合成樹脂性の後挾持部材と、前記表示パネルの周縁部に一端が接続され、電子部品が実装されているフレキシブルプリント基板と、該フレキシブルプリント基板の他端に接続され、前記第２枠部に取付けられているプリント回路基板とを備える（例えば、特許文献１参照）。   A thin display device such as a liquid crystal television includes a display panel having a display surface on the front side and a rectangular parallelepiped, a first ring plate portion facing the front surface of the peripheral edge of the display panel, and an outer edge of the first ring plate portion. A metallic front holding member having a first frame portion extending rearward, a second annular plate portion facing the rear surface of the peripheral edge portion of the display panel, and an outer edge of the second annular plate portion extending backward. A synthetic resin rear holding member having a second frame portion that is held between and holding the peripheral portion of the display panel between the first frame portion and one end connected to the peripheral portion of the display panel And a flexible printed circuit board on which electronic components are mounted, and a printed circuit board connected to the other end of the flexible printed circuit board and attached to the second frame portion (see, for example, Patent Document 1).

近年の表示装置における表示パネルは大型化及び高精細化の傾向にあり、これに伴い、フレキシブルプリント基板に実装されている電子部品の消費電力が増加し、発熱量も増加することになるため、特許文献１にあっては前記フレキシブルプリント基板と前記前挾持部材との間に、絶縁体からなる熱伝導性部材を設け、前記電子部品により発熱した熱を熱伝導性部材から前挾持部材へ逃がすことにより前記電子部品の温度上昇を抑制するように構成されている。   In recent years, display panels in display devices tend to be larger and higher definition, and accordingly, the power consumption of electronic components mounted on a flexible printed circuit board increases and the amount of heat generated also increases. In Patent Document 1, a heat conductive member made of an insulator is provided between the flexible printed circuit board and the front holding member, and heat generated by the electronic component is released from the heat conductive member to the front holding member. Thus, the temperature rise of the electronic component is suppressed.

また、前記電子部品により発熱した熱により前記プリント回路基板が熱膨張し、該プリント回路基板に反りが発生し易くなるため、前記第１枠部のプリント回路基板と対向する複数の箇所に合成樹脂製のクリップを取付けたり、又は第１枠部のプリント回路基板と対向する箇所に帯状のクッション材を貼付けることによりプリント回路基板の反りを抑制するように構成された表示装置も開発されている。   In addition, since the printed circuit board is thermally expanded by heat generated by the electronic component and the printed circuit board is likely to be warped, a synthetic resin is formed at a plurality of locations facing the printed circuit board in the first frame portion. A display device configured to suppress warpage of the printed circuit board by attaching a clip made of plastic or by attaching a band-shaped cushion material to a portion of the first frame portion facing the printed circuit board has also been developed. .

また、近年の表示装置は狭額縁化及び薄型化の傾向にあり、これに伴い、前挾持部材及び後挾持部材間の間隔が狭くなり、前記プリント回路基板と前記第１枠部間の間隔が狭くなるため、熱膨張により前記プリント回路基板に反りが発生したとき、該プリント回路基板に実装されている電子部品が金属製の第１枠部と接触し、ショートする可能性が高くなるため、前記第１枠部のプリント回路基板との対向箇所に絶縁シートを貼付け、熱膨張によりプリント回路基板に反りが発生したときにおいてもショートすることがないように構成された表示装置も開発されている。
特開２００７−２２６０６８号公報 Further, display devices in recent years tend to be narrower and thinner, and accordingly, the distance between the front holding member and the rear holding member is narrowed, and the distance between the printed circuit board and the first frame portion is reduced. Since the printed circuit board is warped due to thermal expansion, the electronic component mounted on the printed circuit board comes into contact with the first metal frame portion and is likely to be short-circuited. There has also been developed a display device that is configured so that an insulating sheet is attached to a portion of the first frame portion facing the printed circuit board so that the printed circuit board is not short-circuited due to thermal expansion. .

この発明にあっては、熱膨張によりプリント回路基板に反りが発生する際、該プリント回路基板の反りを、前挾持部材と一体に設けられている抑制凸部が抑制するため、部品点数を増加することなくプリント回路基板に実装されている電子部品が前挾持部材に接触するのを防ぐことができる。従って、狭額縁化及び薄型化される表示装置の部品点数を増加することなくプリント回路基板部分でのショートを防ぐことができ、コストを低減することができる。   In this invention, when the printed circuit board is warped due to thermal expansion, the warped part of the printed circuit board is restrained by the restraining convex portion provided integrally with the front holding member, so the number of parts is increased. Thus, it is possible to prevent the electronic component mounted on the printed circuit board from coming into contact with the front holding member. Therefore, it is possible to prevent a short circuit in the printed circuit board portion without increasing the number of parts of the display device to be narrowed and thinned, thereby reducing the cost.

本発明によれば、熱膨張によりプリント回路基板に反りが発生する際、該プリント回路基板の反りを、前挾持部材と一体に設けられている抑制凸部が抑制するため、部品点数を増加することなくプリント回路基板に実装されている電子部品が前挾持部材に接触するのを防ぐことができる。従って、狭額縁化及び薄型化される表示装置の部品点数を増加することなくプリント回路基板部分でのショートを防ぐことができ、コストを低減することができる。   According to the present invention, when warpage occurs in the printed circuit board due to thermal expansion, the warpage of the printed circuit board is suppressed by the restraining convex portion provided integrally with the front holding member, so that the number of parts is increased. The electronic component mounted on the printed circuit board can be prevented from coming into contact with the front holding member without any trouble.

ランプ４１は両端部に電極を有する冷陰極管又は熱陰極管であり、シャーシ４２内の両側に並設された保持部に両端部が保持され、また、中間部がランプクリップによりシャーシ４２の後壁に保持されている。   The lamp 41 is a cold-cathode tube or a hot-cathode tube having electrodes at both ends, and both ends are held by holding portions arranged in parallel on both sides in the chassis 42, and an intermediate portion is placed behind the chassis 42 by a lamp clip. Held on the wall.

キャビネット６は、前側の第１環板部２１を被覆する装飾板部６１、及び該装飾板部６１の外縁から後方へ延出され、第１枠部２２の周縁部を被覆する枠部６２と、装飾板部６１の内側から後方へ突出する筒形ボス６３とを有し、合成樹脂材により一体に成形され、筒形ボス６３内に螺着する雄螺子によりシャーシ４２の周縁部に取付けられている。   The cabinet 6 includes a decorative plate portion 61 that covers the first ring plate portion 21 on the front side, and a frame portion 62 that extends rearward from the outer edge of the decorative plate portion 61 and covers the peripheral edge of the first frame portion 22.

Further, the plate wall portion has a cylindrical boss protruding forward, and is attached to the peripheral portion of the chassis 42 by a male screw screwed into the cylindrical boss.

以上のように構成された表示装置は表示パネル１の周縁部を前後から挾持している前挾持部材２と後挾持部材３との間の隙間は比較的狭く、表示パネル１の表示面積に対して小型化及び薄型化されており、後挾持部材３の第２枠部３２に取付けられているプリント回路基板９と前挾持部材２の第１枠部２２との間の間隔も比較的狭くなっている。   In the display device configured as described above, the gap between the front holding member 2 and the rear holding member 3 holding the peripheral edge of the display panel 1 from the front and rear is relatively narrow, and the display area of the display panel 1 is relatively small. The distance between the printed circuit board 9 attached to the second frame portion 32 of the rear holding member 3 and the first frame portion 22 of the front holding member 2 is also relatively small. ing.

このように構成されている表示装置において、プリント回路基板９に実装されている電子部品９１が発生する熱等によりプリント回路基板９が熱膨張し、該プリント回路基板９が第１枠部２２側へ反り変形する際、第１枠部２２と一体成形されている抑制凸部２３にプリント回路基板９の接地部９ｂが接触し、プリント回路基板９の反り変形を抑制することができる。従って、プリント回路基板９に実装されている電子部品９１が、金属製の第１枠部２２（前挾持部材２）に接触するのを防ぐことができ、プリント回路基板９部分でのショートを防ぐことができる。また、抑制凸部２３は第１枠部２２と一体成形されているため、部品点数の増加がなく、組立作業性を高めることができ、コストを低減できる。また、プリント回路基板９の接地部９ｂが抑制凸部２３に接触した際、前挾持部材２によりプリント回路基板９をアースすることができる。   In the display device configured as described above, the printed circuit board 9 is thermally expanded by heat generated by the electronic component 91 mounted on the printed circuit board 9, and the printed circuit board 9 is on the first frame portion 22 side. When warping and deforming, the grounding portion 9b of the printed circuit board 9 comes into contact with the restraining convex portion 23 formed integrally with the first frame portion 22, and warping deformation of the printed circuit board 9 can be suppressed. Therefore, the electronic component 91 mounted on the printed circuit board 9 can be prevented from coming into contact with the metal first frame portion 22 (the front holding member 2), and a short circuit at the printed circuit board 9 portion can be prevented. be able to. Moreover, since the suppression convex part 23 is integrally molded with the 1st frame part 22, there is no increase in a number of parts, an assembly workability | operativity can be improved and cost can be reduced. Further, when the grounding portion 9 b of the printed circuit board 9 comes into contact with the restraining convex portion 23, the printed circuit board 9 can be grounded by the front holding member 2.

図６は要部の他の構成を示す拡大断面図である。以上説明した実施の形態では、プリント回路基板９の接地部９ｂと僅かに離隔して対向する抑制凸部２３を備える構成について説明したが、その他、図６に示すように抑制凸部２３はプリント回路基板９の熱膨張に関係なく該プリント回路基板９の接地部９ｂと接触する構成としてもよい。この構成にあっては、第１枠部２２の抑制凸部２３が非熱膨張のプリント回路基板９に接触しているため、プリント回路基板９の取付け強度を高めることができるとともに、特別のアース用部品を増加することなくプリント回路基板９をアースすることができる。   FIG. 6 is an enlarged cross-sectional view showing another configuration of the main part. In the above-described embodiment, the configuration including the suppression convex portion 23 facing the grounding portion 9b of the printed circuit board 9 with a slight distance therebetween is described. However, as shown in FIG. The circuit board 9 may be in contact with the ground portion 9b of the printed circuit board 9 regardless of the thermal expansion of the circuit board 9. In this configuration, since the restraining convex portion 23 of the first frame portion 22 is in contact with the non-thermal expansion printed circuit board 9, the mounting strength of the printed circuit board 9 can be increased, and a special grounding can be achieved. The printed circuit board 9 can be grounded without increasing the number of components.
