Abstract
"aparelho de projeção para produzir imagens em cores com itens causadores de mancha reduzidos"é descrito um aparelho de projeção para produzir imagens em cores com itens causadores de mancha reduzidos compreendendo :pelo menos três fontes de luz de banda estreia com primeira ,segunda e terceira bandas de comprimento de onda visíveis;uma fonte de imagem digital provendo dados de imagem digital em cores ;pelo menos um modulador espacial de luz para forma uma imagem em cores usando luz em resposta aos dados de imagem digital em cores;uma superficie de exibição de projeção incluindo uma camada reflexiva que reflete iluminação incidente na primeira ,segunda e terceira banda de comprimento de onda; e um agente fluorescente que absorve uma fração da luz incidente na primeira bandas de comprimento de onda visíveis e emite luz em um primeira banda de comprimento de onda visí vel emissiva correspondente ;e um lente de projeção que projeta o imagem em cores na superficie de exibição de projeção ;em que o retorno da luz na superficie de exibição de projeção contém luz tanto na primeira banda de comprimento de onda visível incidente quanto na primeira banda de comprimento de onda visível emissiva ,dessa forma reduzindo itens causadores de mancha.
