Description
図1〜図9を参照して、本発明の実施の形態1に係る表示ユニット10について説明する。なお、理解を容易にするために、表示ユニット10が、野外で表示ユニット10の正面が地面に対して垂直に設置されたと仮定し、地面と表示ユニット10の正面とに平行な方向をX軸方向、地面に対して垂直な方向をY軸方向、X軸方向とY軸方向とに垂直な方向をZ軸方向として説明する。これらの軸方向の規定は、他の実施の形態においても同様である。
さらに、防水フィルム50がケース40を覆うので、ケース40の経年劣化を抑制できる。
まず、配線を備えた回路基板20と防水フィルム50とを準備する。次に、発光素子30の電極37を、回路基板20の配線にリフロー方式によりハンダ付けして、各発光素子30を回路基板20の実装面22に実装する(ステップS11)。
次に、発光素子30が実装された回路基板20をケース40に載置する(ステップS12)。
以上によって、表示ユニット10を製造できる。
図10を参照して、本実施の形態2に係る表示ユニット11を説明する。
実施の形態1においては、防水フィルム50と回路基板20の実装面22は、直接接しているが、防水フィルム50の実装面22に対向する面52と、実装面22との間に、粘着性を有する部材が設けられてもよい。
図11を参照して、本実施の形態3に係る表示ユニット12を説明する。
防水フィルム50の面52と回路基板20の実装面22との間に設けられる部材は、粘着層102に限られない。
図12を参照して、本実施の形態4に係る表示ユニット13を説明する。
実施の形態1〜実施の形態3において、防水フィルム50は透光性を有する。表示ユニット13は、防水フィルム50に代えて、透光性と共に光拡散性を有する防水フィルム54を備える。その他の構成は実施の形態1と同様である。
図13〜図16を参照して、本実施の形態5に係る表示ユニット14を説明する。
実施の形態4においては、防水フィルム54が、外光106を拡散して画像のコントラストの低下を抑制する。本実施の形態に係る表示ユニット14は、他の部材を備えることによって、画像のコントラストの低下を抑制する。
マスク板110は、例えば、黒色の樹脂から射出成形によって作製される。
図17を参照して、本実施の形態6に係る表示ユニット15を説明する。
実施の形態2、3において、表示ユニット11、12は、防水フィルム50の面52と回路基板20の実装面22との間に、面52と実装面22との密着性を向上させる部材を備える。防水フィルム50の面52と回路基板20の実装面22との間に設けられる部材は、面52と実装面22との密着性を向上させる部材に限られない。
マイクロレンズ122は、発光素子30の光出射面32からの出射光を集光する。
図18〜図21を参照して、本実施の形態7に係る表示装置18を説明する。
複数の表示ユニット10〜15を組み合わせることによって、より大型の表示装置18を構成できる。表示装置18は、競技場、ビルの壁面等の野外に設置される。
マイクロレンズシート120は、防水フィルム50、54の面52と回路基板20の実装面22との間に限られず、防水フィルム50、54の面56の上に設けられてもよい。
