以下の共有であり同時係属中の米国特許出願を本明細書に参照として引用する:米国特許出願シリアル番号11/212,166、題名、凹面トランス反射体を具備する光循環キャビティを有する直接照明バックライト;同11/458,891、題名、2機能性方向転換器を具備する光源を有する直接照明バックライト;同11/466,628、題名、凹面トランス反射体を具備する光循環キャビティを有するエッジ照明バックライト;同xx/xxx、xxx、題名、凹面トランス反射体を具備する光循環キャビティを有する直接照明バックライトを形成する方法(代理人ドケット番号61199US006)、である。
比較のバックライトキャビティを光抽出素子またはフィルムをLEDの上方に有しない構成にした。背面反射体のトップ(すなわち、反射基板)から拡散板の底までのキャビティ深さを28mmにした。
バックライトキャビティは、光抽出素子として使用される3M社から入手可能なBEFフィルムIIIを含んでいた。そのフィルムをアクリル板上にプリズムがLEDに対向するようにして支持させ、(すなわち、LED列の方向に対して平行に)水平に配向させた。キャビティ深さは反射基板のトップから拡散板の底までが約28mm、そして部分反射体を反射基板の上約12.7mmに配置した。反射基板は米国特許第6,096,247号(Ulsh等)に記載の技術を使用して作製されたフレームエンボスESRであった。
バックライトキャビティは、光抽出素子として使用されるキューブコーナー光抽出フィルムを含んでいた。このフィルムは0.25mm(10ミル)厚さの単層ポリカーボネートシート材料であり、それは1つの主要面が平坦で平滑であり、反対表面に形成されたプリズムパターンを有した。プリズムは、3M社から入手可能な3M(登録商標)スコッチライト(Scotchlite、登録商標)反射材6260高光沢フィルムに使用されるピラミッド状キューブコーナー配列と同一であり、ピラミッド状配列は片傾斜キューブコーナープリズムで特徴付けられ、その高さ(三角形の底面からキューブコーナーの頂点まで)は約87.5μm(約3.5ミル)であり、その底面三角形は約55°、55°、および70°の角度を有する。この抽出フィルムは、フィルムの構造化側がLEDに面するように配向させた。フィルムをアクリル板で支持した。キャビティ深さは、反射基板のトップから拡散板の底までが28mmであり、光抽出フィルムは反射基板の上方約12.7mmに設置した。反射基板はESRであった。
バックライトキャビティは、光抽出素子として利用される2つの光抽出フィルムを含んでいた。各々の光抽出フィルムは、実施例Bに使用された光抽出フィルムと同一であった。第1フィルムはキューブコーナー要素をLEDに対向するようにしてアクリル板上に支持させた。第2フィルムはキューブコーナー要素を(アクリル板に接触させて)LEDに対向するようにしてアクリル板の反対面に支持させた。キャビティは約18mm深さであり、光抽出フィルムは反射基板の上方約12.7mmに配置した。反射基板はESRであった。
バックライト空隙は、光抽出素子として利用される2つの光抽出フィルムを具備した。各々の光抽出フィルムは実施例Bに使用された光抽出フィルムと同一であった。第1フィルムはキューブコーナー要素をLEDに対向するようにしてアクリル板上に支持させた。アクリル板の反対面は拡散フィルムを具備した。第2フィルムはキューブコーナー要素をLEDに対向する(アクリル板に接触させて)ようにして拡散フィルムを有するアクリル板の面に固定させた。キャビティは約28mm深さであり、光抽出フィルム構築物は反射基板の上方約12.7mmに配置した。反射基板はESRであった。
バックライトキャビティは、それが0.13mm(5ミル)厚さのポリエチレンテレフタレート(PET)製ベースフィルムの上に約1.586の屈折率を有する樹脂で、そこに形成させたプリズム構造化表面722を有する硬化樹脂層からなることを除いては、光抽出素子として本開示の図7b〜eに関して記述した光抽出フィルムを具備した。光抽出フィルムは、約0.15mm(6ミル)の公称の全体の厚さを有した。構造化表面上の各プリズム726は、約150μmの特性的長さλ(図7e参照)、それぞれ約68μmと4μmの最高幅Wmaxおよび最低幅Wmin、並びにそれぞれ約25μmと1μmの最高の高さおよび最低の高さを有した。各プリズムの傾斜したプリズム表面は、実質的に平坦な横断方向断面(図7dのy−z平面参照)であり、その間に約96°の頂角を形成した。プリズムは図7b〜eに図示したように構造的対称性を有し、片勾配角度θは約19°であった。θフィルムはプリズムをLEDに対向させ、プリズムを水平に配向させて(すなわち、角プリズムはLED列の方向に平行に広がる)、アクリル板上に支持させた。キャビティ深さは、反射基板のトップから拡散板の底までで38mmであり、光抽出素子は反射基板の上方約12.7mmに設置した。反射基板はESRであった。
バックライトキャビティは光抽出素子として実施例Eの光抽出フィルムを具備した。プリズムをLEDに対向させ、かつ水平に配向(すなわち、各プリズムがLEDの列の方向に平行に広がる)させて、フィルムをアクリル板上で支持した。キャビティ深さは、反射基板のトップから拡散板の底までが28mmであり、光抽出構築物は反射基板の上方約12.7mmに設置した。反射基板はESRであった。
実施例A〜Fの比較を表1に示す。相対的効率パラメータは各々のバックライト構成に対して、実施例の平均輝度を対照例の平均輝度で除算して計算し、各々の場合の平均輝度はそれぞれのバックライトの実質的な全出力面積に対して計算した。輝度の不均一性パラメータは各々のバックライト構成に対して、標準輝度偏差をバックライトの実質的な全出力面積に渡る平均輝度で除算して計算した。色不均一性パラメータΔuvは各々のバックライト構成に対して、実施例の平均的な色からの各点における色彩偏差の平均値として計算し、かつ、色彩は色彩空間におけるCIEu'v'として表現する。従って、
