Abstract

TELA DE PROJEÇÃO DO TIPO REFLETIVA A presente invenção refere-se a uma tela de projeção do tipo refletiva que possui ganho uniformemente alto ao longo de uma ampla faixa de ângulos de observação. A tela de projeção inclui um substrato de sustentação refletor de luz com duplo propósito, que inclui pelo menos uma folha de filme fibrila plexifilamentar de fiação rápida não pigmentada que possui uma refletância de luz de mais de cerca de 85% e um brilho de menos de cerca de 10% quando medido em um ângulo de incidência de 60° e uma camada de difusão óptica de um polímero transmissivo de luz processável por fusão que contém partículas de aumento da difusão que cobrem pelo menos uma superfície do substrato. A tela de projeção possui um ganho óptico de entre cerca de 0,90 a cerca de 2,0 e o ganho óptico desvia em não mais de cerca de 8% ao longo de ângulos de observação entre -60° a +60°. A tela de projeção possui boa drapeabilidade, flexibilidade quanto ao dobramento e capacidade de ser depositada e pendurada de forma plana. A tela de projeção pode também ser reciclada.
