Abstract
【課題】導光板の不均一な輝度を改善し、バックライトモジュール全体の光射出外観の均一性を改善できる導光板、バックライトモジュール及び表示デバイスを提供する。【解決手段】導光板200は、本体210と、複数の微細構造220と、を備える。本体は、光学面211、光入射面212、逆光入射面213、少なくとも1つの側面214、および少なくとも1つの円弧面215を有する。光入射面及び逆光入射面は、それぞれ光学面の対向する両側に接続され、側面は、光学面、光入射面及び逆光入射面に接続され、円弧面は、側面と逆光入射面との間に位置する。本体は、光学面を貫通する貫通孔216を備える。微細構造は、側面、円弧面及び/又は逆光入射面の貫通孔に近い一部に設けられる。微細構造は、斜面221を有し、光を光入射面から離れた貫通孔側の暗影に効果的に反射し、貫通孔付近の輝度ムラを大幅に改善する。【選択図】図1
