    • The present invention is a tinted, optical adhesive for use in making plasma display filters comprising a substantially acid free, pressure-sensitive adhesive (PSA) containing a narrow-band, visible spectrum dye (e.g. less than 30 nm bandwidth) and a broader-band, near infra-red spectrum dye (e.g. greater than 200 nm), the second dye providing enhanced thermal stability as well as near infra-red (NIR) blocking. Further, acid-free adhesives offer improved stability of light control dyes. In the present invention, porphyrin-based dyes combined with acrylate-based, pressure-sensitive optical adhesives are preferred. Invention offers reduced number of functional layers in an optical filter structure as well as reduced number of manufacturing (lamination) steps in the optical filter/plasma display assembly process.
    • 本发明是用于制造等离子体显示过滤器的着色光学粘合剂,其包含基本上无酸的压敏粘合剂(PSA),其包含窄带可见光谱染料(例如小于30nm带宽) 近红外光谱染料(例如大于200nm),第二种染料提供增强的热稳定性以及近红外(NIR)阻挡。 此外,无酸粘合剂提供了光控染料的改进的稳定性。 在本发明中,优选与基于丙烯酸酯的压敏光学粘合剂结合的卟啉系染料。 本发明在光学滤波器结构中提供了减少数量的功能层,并且在滤光器/等离子体显示组件工艺中减少了制造(层压)步骤。
