Abstract
Description
図1は、実施の形態に係る画像表示装置10の外観斜視図である。図2は、実施の形態に係る液晶モジュール100の分解斜視図である。
次に、サポートピン200について詳細に説明する。
次に、サポートピン200と下フレーム140、140aとの組み付けについて説明する。
まず、下フレーム140における孔部141について説明する。図8は、実施の形態に係る下フレーム140の孔部141の概略構成を示す平面図である。孔部141は、X軸方向に長尺な貫通孔である。孔部141は、第一係合部1411と、第二係合部1412と、中間部1413とを備えている。第一係合部1411と、第二係合部1412は、孔部141の長手方向における両端部である。つまり、第一係合部1411と、第二係合部1412は、長手方向で対向する一対の縁部である。中間部1413は、第一係合部1411と、第二係合部1412とに挟まれた部分である。
次いで、他の下フレーム140aにおける孔部141aについて説明する。図12は、実施の形態に係る他の下フレーム140aの孔部141aの概略構成を示す平面図である。孔部141aは、孔部141と比べて、第二係合部1412aに拡幅部1414aが形成されている点で異なる。このため、以降の説明においては、孔部141と同一の部分については、同一の符号を付してその説明を省略する。
次に、組み立て後における実施の形態に係るサポートピン200とその周囲に配置された部材との位置関係について説明する。
以上のように、本実施の形態に係る画像表示装置10は、表示パネル102の背面側に配置された下フレーム140、140aと、下フレーム140、140aにおける前面側に配置される複数のLED1091と、複数のLED1091を覆うようにLED1091の前面側に配置されて、当該LED1091からの光を均一化する輝度均一板107と、輝度均一板107の前面側に配置されて、輝度均一板107を透過した光を拡散する拡散板106と、下フレーム140、140aに固定された状態で輝度均一板107を貫通するように延設され、先端で拡散板106を支持するサポートピン200とを備え、サポートピン200の先端は、凸曲面状に形成されている。
以上のように、本出願において開示する技術の例示として、実施の形態を説明した。しかしながら、本開示における技術は、これらに限定されず、適宜、変更、置き換え、付加、省略などを行った実施の形態にも適用可能である。また、上記実施の形態で説明した各構成要素を組み合わせて、新たな実施の形態とすることも可能である。そこで、以下、他の実施の形態を例示する。
