Abstract

"superfície de exibição de projeção para receber luz de um projetor"é descrita uma superfície de exibição para reduzir itens causadores de mancha de um projetor com pelo menos uma fonte de luz de banda de comprimento de onda vísivel incidente,em que a banda de comprimento de onda vísivel incidente tem um comprimento de onda de pico incidente e uma largura de banda incidente,compreendendo:um substrato com camada refletiva que reflete luz incidente em pelo menos uma banda de comprimento de onda visível incidente;e um agente fluorescente distribuído sobre a camada refletiva,em que o agente fluorescente absorve uma fração da luz na banda de comprimento de ond visível incidente e emite luz em uma banda de comprimento de onda visível emissiva com um comprimento de onda de pico emissivo e uma largura de banda emissiva; em que a luz de retorno da superfície de exibição de projeção contém luz tanto na banda de comprimento de onda visível incidente quanto na banda de comprimento de onda visível emissiva,dessa forma reduzindo itens causadores de mancha.
