Abstract
Description
かかる液晶表示装置において、上記液晶パネルの前面側には枠体であるベゼル(表枠)が配置され、該パネルの背面側には、該パネルとその光源であるバックライト装置との間にフレーム(例えば樹脂製フレームはPシャーシ(プラスチックシャーシ)とも呼ばれる。)が配置されている。このベゼルおよびフレームは、上記液晶パネルの中央における表示領域(アクティブエリア)を矩形状に囲む額縁形状に形成されており、該液晶パネルの前後両側から該パネルの矩形状の周縁部を狭持している。
一方、上記ネジのような強制的な固定器具に代えて、フレーム外側面に装着されるクリップ形状の器具(以下「基板クリップ」という。)の使用が行われている。かかる基板クリップは、該クリップとフレーム外側面との間に回路基板を挟み込んだ状態で当該フレーム外側面に装着されるように構成されることにより、回路基板に生じる反り等の多少の変形を許容しつつ当該回路基板をフレーム外側面の所定位置に保持することができ、且つ、回路基板はフレームの長手方向には固定されておらず、1方向にのみ自由に動くことができる状態となる。よって、液晶パネルが微小に動いた際も、それに追従して回路基板も動くため、フレキシブル配線基板が破断するのを防ぐことができる。
そこで本発明は、上記従来の問題点に鑑みてなされたものであり、その主な目的は、より安定した装着状態を保ち得る基板クリップと、該基板クリップによって上記回路基板をフレームの外側面の所定位置に保持した液晶表示装置を提供することである。
ここで上記基板クリップは、上記装着時において上記フレームの外側面に対向して配置されるプレート状本体部と、該本体部の一端側であって上記装着時において上記フレームに設けられた前面側クリップ取付部と係合する前面側係合部と、該本体部の他端側であって上記装着時において上記フレームに設けられた背面側クリップ取付部と係合する背面側係合部とを有している。さらに上記基板クリップには、上記前面側係合部の近傍において、上記液晶パネルが狭持されるように上記ベゼルが所定位置に配置された際に該ベゼルの周縁部の一部が接し得るベゼル載置部が形成されていることを特徴とする。
なお、本明細書ならびに特許請求の範囲において「前面」とは、液晶表示装置及び液晶パネルにおける映像が表示される側(即ち視聴者に面する側)の面をいい、「背面」とは、当該前面の裏側の面をいう。
そして、上記フレームには、上記一対の前面側係合爪及び一対の背面側係合爪にそれぞれ対応する位置において、該係合爪をそれぞれ嵌合し得る一対の前面側嵌合孔及び一対の背面側嵌合孔が形成されていることを特徴とする。
かかる構成の液晶表示装置では、基板クリップのプレート状本体部におけるフレーム前後方向の両端に各々一対の上記前面側係合爪および上記背面側係合爪が設けられ、それらを対応する一対の上記前面側嵌合孔および上記背面側嵌合孔にそれぞれ嵌合することができるため、より安定して上記基板クリップを所定位置に配置することができる。
かかる構成の液晶表示装置では、上記一対の前面側嵌合孔のうちの一方が長溝状に形成されており且つ上記一対の背面側嵌合孔のうちの一方が長溝状に形成されている。このことにより、フレームに加工誤差や熱収縮が生じた場合であっても、かかる誤差や熱収縮による一対の嵌合孔間の距離が変動する影響を回避し、上記係合爪部と嵌合孔との嵌合不良を防止することができる。
かかる構成の液晶表示装置では、上記プレート状本体部の一端から液晶パネルの中心方向に張り出すように前面側係合部が設けられている結果、その張り出した部位を利用することによりベゼル載置部をより広く形成することが可能となる。そして、上記突条部(リブ)を設けることにより、より安定してベゼルを載置することができるために基板クリップのがたつきをより一層確実に防止することができる。また、突条部(リブ)を設けることにより、基板クリップ自体(特にパネル載置部)の機械的強度を向上させることができる。
かかる基板クリップは、上記フレームに装着された時に該フレームの外側面に対向して配置されるプレート状本体部と、上記本体部の一端側であって上記装着時において上記フレームに設けられた前面側クリップ取付部と係合する前面側係合部と、該本体部の他端側であって上記装着時において上記フレームに設けられた背面側クリップ取付部と係合する背面側係合部とを有する。さらに上記前面側係合部の近傍において、上記液晶パネルが狭持されるように上記ベゼルが所定位置に配置された際に該ベゼルの周縁部の一部が接し得るベゼル載置部が形成されていることを特徴とする。
本発明に係る回路基板保持用の基板クリップを使用することにより、上述したとおり、所定の装着位置において当該基板クリップ自体のがたつきが防止されるため、上記フレキシブル配線基板を介して液晶パネルに接続されている回路基板の少なくとも一部をフレームの外側面に安定的に保持することができる。
かかる構成の基板クリップは、上記前面側係合爪および上記背面側係合爪がそれぞれ一対(二つ)設けられているので、より安定してフレーム外側面の所定位置に配置することができる。
かかる構成の基板クリップでは、上記プレート状本体部の一端から液晶パネルの中心方向に張り出すように前面側係合部が設けられている結果、その張り出した部位を利用することによりベゼル載置部がより広く形成される。そして、上記ベゼル載置部として上記ベゼルが配置される方向に突出する突条部(リブ)が形成されているので、上記ベゼルをより安定して配置することができる。また、突条部(リブ)を設けることにより、基板クリップ自体(特にパネル載置部)の機械的強度の向上が実現される。
なお、以下の図面において、同じ作用を奏する部材、部位には同じ符号を付し、重複する説明は省略または簡略化することがある。また、各図における寸法関係(長さ、幅、厚さ等)は、必ずしも実際の寸法関係を正確に反映するものではない。
図1に示されるように、本実施形態に係る液晶表示装置100は、大まかにいって、矩形状の液晶パネル10と、当該液晶パネル10の背面側(即ち図1における下側)に配置された額縁状のフレーム30と、当該液晶パネル10の前面側(即ち図1における上側)に配置された額縁状のベゼル(前枠)20とを備えている。また、フレーム30のさらに背面側には、所定の外部光源72を有するバックライト装置70が備えられている。
図示されるように、バックライト装置70は、複数本の線状の光源(例えば蛍光管、典型的には冷陰極蛍光管)72と、当該光源72を収納するケース(シャーシ)74とを備えている。ケース74は、表側に向けて開口した箱形形状を有しており、ケース74内には、光源(蛍光管)72が平行に配列されており、ケース74と光源72との間には、光源72の光を効率的に視聴者側に反射させるための反射部材76が配置されている。
図1に示されるように、液晶パネル10は、概して、全体として矩形の形状を有しており、その中央領域には、画素が形成されている領域であって画像を表示する表示領域10Aが形成されている。通常の液晶パネルと同様、本実施形態に係る液晶パネル10は、互いに対向する一対の透光性のガラス基板11,12と、その間に封入された液晶層(図示せず)とから構成されるサンドイッチ構造を有している。かかる基板11,12には、製造工程でそれぞれマザーガラスと称される大型の母材から切り出されたものを使用している。上記一対の基板11,12のうち、前面側がカラーフィルタ基板(CF基板)11であり、背面側がアレイ基板(TFT基板)12である。
図2に示されるように、本実施形態に係るフレーム30は、全体の構成として液晶パネル10の背面側に配置され、該パネル10の中央における表示領域10Aを矩形状に囲むように形成された平面視で枠形状の部品であり、その前面30Aの内周寄り部分に、上記液晶パネル10の周縁部が配置される。そして、図3に示されるように、前面30Aの内周寄り部分に配置された液晶パネル10の周縁部にフレキシブル配線基板14を介して接続されている回路基板16は、フレキシブル配線基板14の可撓性を利用して、フレーム30の前面30Aを越えてその外側面30Bに誘導、配置されている。
而して、本実施形態に係る基板クリップ50は、所定の位置(図3参照)に装着した際にフレーム30の外側面30Bに対向して配置されるプレート状の本体部52を備える。
その本体部52の一端であって装着時においてフレーム30の前面側に配置される方の端部には、本体部52の幅方向の両端付近に左右一対の前面側係合部54,55が形成されている。他方、本体部52の一端であって装着時においてフレーム30の背面側に配置される方の端部には、本体部52の幅方向の両端付近に左右一対の背面側係合部56,57が形成されている。さらに、前面側係合部54,55の上面側(即ち装着時においてベゼル20に対向する側)には、本実施形態に係るベゼル載置部60が形成されている。以下、詳細に説明する。
また、本実施形態に係るベゼル載置部60は、液晶パネル10の中心方向に張り出した上記前面側係合部54,55における延伸部54A,55Aのそれぞれの上面側(即ち装着時においてベゼル20に対向する面側)に設けられた当該上面側からみて十文字状にパネル前面方向に突出した突条部(十文字リブ)62A,62Bを備えている。各突条部62A,62Bの上端は同一の高さで且つフラットに形成されている。
このように一対の背面側係合部56,57(係合爪56A,57A)を左右非対称に形成することによって、基板クリップ50をフレーム外側面30Bに装着する際の当該基板クリップ50の正しい向き(方向)を作業者は容易に認識することができる。このため、基板クリップ50の向きを逆にして装着するといった作業ミスの発生を防止し、効率よく正確に基板クリップ50を正しい向きに装着することができる。なお、本実施形態においては、背面側係合部について左右非対称の形成を実施しているが、前面側係合部を左右非対称に形成した場合でも同様の効果を奏することができる。
さらに、幅広な第1背面側係合爪56Aの先端はテーパ状に成形されており、係合爪56Aの中央付近には係合段差56Bが形成されている。
図5に示されるように、フレーム30(長辺部30E)の前面30Aの外周寄りには、基板クリップ50を所定の装着位置に装着した際の上記一対の前面側係合爪54B,55Bにそれぞれ対応する位置に、本実施形態に係る前面側クリップ取付部44,45に相当する一対の前面側嵌合孔44A,45Aが設けられている。
即ち、図示されるように、本実施形態においては、第1フレーム構成部材32の前面30Aに形成された嵌合孔44Aは、対応する係合爪54Bがちょうど嵌り込む孔サイズに形成されている一方、第2フレーム構成部材33の前面30Aに形成された嵌合孔45Aは、対応する係合爪55Bのサイズよりも長辺部30Eに沿う方向に長い長溝状に形成されている。
即ち、図示されるように、本実施形態においては、第1フレーム構成部材32の外側面の下部(即ちバックライト装置70寄り)に、対応する第1背面側係合部56の係合爪56Aが嵌り込む第1背面側嵌合孔46Aと該嵌合孔46Aを構成する周壁部46Bとが形成されている。かかる周壁部46Bのフレーム外側面30Bに対向する面の下部は開放されており、当該開放部に係合爪56Aのテーパー状先端部が配置されると、図6に示されるように、係合段差56Bに周壁部46Bのエッジ部分が係合する(引っ掛かる)こととなり、結果、基板クリップ50の当該クリップ取付部46からの抜け落ち(脱落)を確実に防止することができる。なお、図示されるように、第1背面側嵌合孔46Aは、第1背面側係合爪56Aの幅よりも長辺部30Eに沿う方向に長い長溝状に形成されている。
一方、図示されるように、本実施形態においては、第2フレーム構成部材33の外側面の下部(即ちバックライト装置70寄り)に、対応する第2背面側係合部57の係合爪57Aが嵌り込む第2背面側嵌合孔47Aと該嵌合孔47Aを構成する周壁部47Bとが形成されている。図示されるように、第2背面側嵌合孔47Aは、第2背面側係合爪57Aがちょうど嵌り込む孔サイズに形成されている。
具体的には、基板クリップ50のプレート状本体部52とフレーム外側面30Bとの間に二つの回路基板16の端部を挟み込んだ状態で、上記一対の前面側係合爪54B,55Bを各々対応する前面側嵌合孔44A,45Aに挿入して嵌合させるとともに、上記一対の背面側係合爪56A,57Aを各々対応する背面側嵌合孔46A,47Aに挿入して嵌合させる。このように基板クリップ50(本体部52)の前面側及び背面側を各々一対の係合部(前面側係合部54,55と背面側係合部56,57)を介してフレーム30に取り付けることにより、安定した装着を実現することができる。
従って、本実施形態に係る液晶表示装置100では、図6に示されるように、ベゼル載置部60(突条部62A,62B)に接するベゼル20が障壁となって基板クリップ50のガタツキが防止され、延いては上記回路基板16をフレーム30の外側面30Bに安定的に保持することができる。また、突条部(リブ)62A,62Bを設けることによって、例えば、単純なプレート(フラット)状ベゼル載置部と比較して当該部分の機械的強度を向上させることができる。
例えば、上記実施形態では、突条部62A,62Bが十文字形状に形成されているが、この形状に限定されない。ベゼル20が安定して接触され得る限り(即ちベゼル20によって基板クリップが押さえつけられてガタツキの発生が抑止され得る限り)において、種々の形状(例えば同心多重円形状のリブ)の突条部を形成することができる。
また、基板クリップ50は、フレーム構成部材32,33の境界部分38に限られず、回路基板16を配置すべき場所に応じてフレーム外側面30Bの任意の場所に装着することができる。
