Description
映像装置に用いる受光装置および映像表示装置に関する。
(実施の形態1)
[1−1.構成]
図1は、実施の形態1による受光装置を備えた薄型表示装置を示す斜視図である。また図1のA部の拡大図も示している。
以上のように構成された受光装置6について、その動作を以下説明する。
図6は照度センサーの受光感度の解析データであり、図5の受光装置において、出射面10の鉛直面に対する出射面角度Aを変化させ、使用環境下における照明光の受光感度と、エネルギースター省エネ規格における光源からの照明光の受光感度の関係を示したものである。この解析データは、インテグラ社製の光シミュレーションソフトウェアであるLumiceptを使用して得られた。なお、解析に用いた受光装置6の導光部8は、厚みが2mm、幅が5mm、長さが10mmの屈折率1.59のポリスチレン製樹脂の透明部材で構成し、入射面9は表示画面2と平行とした。光源条件としては、エネルギースター省エネ規格は導光部入射面9と同一高さで水平方向距離1.5mの位置に、使用環境における光源は導光部入射面9から上方2mの高さに、水平方向からの角度が25°〜70°の範囲で存在していると仮定する。
以下、図9〜11を用いて、実施の形態2を説明する。
本実施の形態における受光装置16は実施の形態1と同様、図1に示す薄型表示装置に用いられている。
以上のように構成された受光装置16について、その動作を以下説明する。
図11は照度センサーの受光感度を説明するための解析データであり、図9の受光装置において、出射面15の鉛直面に対する出射面角度Fを変化させ、使用環境下における照明光の受光感度と、エネルギースター省エネ規格における光源からの照明光の受光感度の関係を示したものである。この解析データは、インテグラ社製の光シミュレーションソフトウェアであるLumiceptを使用して得られた。なお、解析に用いた受光装置16の導光部68は、厚みが2mm、幅が5mm、長さが15mmのポリスチレン製樹脂の透明部材で構成し、入射面9は表示画面2と平行とした。光源条件は図6と同じにした。
