    • Disclosed is a front filter attached to a front surface of a plasma display panel, the front filter comprising: an antireflection coating for preventing reflection of incident light from outside; an optical characteristic film for improving optical characteristics of incident light from the panel, by decreasing brightnesses of red (R) and green (G) rays and by increasing brightness of blue (B) rays; an EMI shielding film for shielding emission of electromagnetic wave; and an NIR blocking film for blocking near infrared rays emitted from the panel, wherein, transmittance of emitted light from the plasma display panel when the emitted light transmits the antireflection coating, the optical characteristic film, the EMI shielding film, and the NIR blocking film is determined in dependence of wavelength of the emitted light, and wherein transmittance of B rays at a wavelength of 454 nm is 50-80%, transmittance of G rays at a wavelength of 525 nm is 40-80%, transmittance of orange rays at a wavelength of 580-592 nm is 5-30%, transmittance of R rays at a wavelength of 610-650 nm is 50-80%, and transmittance of NIR at a wavelength of 850-950 nm is 1-10%.
    • 公开了一种附着在等离子体显示面板的表面上的前部过滤器,前部过滤器包括:防反射涂层,用于防止来自外部的入射光的反射; 通过降低红色(R)和绿色(G)光线的亮度和通过增加蓝色(B)光线的亮度来提高来自面板的入射光的光学特性的光学特性膜; 用于屏蔽电磁波发射的EMI屏蔽膜; 以及用于阻挡从面板发射的近红外线的NIR阻挡膜,其中,当所发射的光透射抗反射涂层,光学特征膜,EMI屏蔽膜和NIR阻挡膜时,来自等离子体显示面板的发射光的透射率 根据发射光的波长确定,并且其中在454nm的波长处的B射线的透射率为50-80%,波长525nm处的G射线的透射率为40〜80%,橙色的透射率在 580-592nm的波长为5-30%,波长为610-650nm的R射线的透过率为50-80%,850-950nm波长的NIR的透射率为1-10%。
