    • The present invention is directed to methods and apparatus for enhancing the performance of visual display units which utilize plasma display panels. More specifically, the present invention provides methods and apparatus for providing an electrical noise suppressing/chromaticity enhancing accessory device for positioning in front of the viewing surface of a plasma display panel. In its most basic embodiment, the accessory device of the present invention comprises a first and a second rigid substrate laminated together by a laminating layer; an optically selective coating providing high photopic transmittance, continuous high electrical conductivity for RFI shielding, and reflectivity specifically within the near-IR region that is mechanically protected by being sandwiched between one rigid substrate and the laminating layer; and, a multiple-dye coating for selectively absorbing IR energy emissions and selectively balancing the chromaticity of the PDP display. The combination of the IR absorption and color-correction due to the multiple-dye coating and the near-IR reflectivity due to the optically selective coating surprisingly results in very good suppression of IR emissions from the PDP within the spectral range of about 800 to about 2500 nm and chromaticity enhancement while simultaneously maintaining good photopic transmittance.
    • 本发明涉及用于增强使用等离子体显示面板的视觉显示单元的性能的方法和装置。 更具体地,本发明提供了用于提供用于定位在等离子体显示面板的观察表面前方的电噪声抑制/色度增强附件装置的方法和装置。 在其最基本的实施例中,本发明的附件装置包括通过层压层层叠在一起的第一和第二刚性基板; 提供高的透光率的光学选择性涂层,用于RFI屏蔽的连续高导电性,以及特别在靠近IR区域内的反射率,其通过夹在一个刚性基板和层压层之间机械地保护; 以及用于选择性吸收IR能量排放并选择性平衡PDP显示器的色度的多染料涂层。 由于多染色涂层的IR吸收和颜色校正以及由于光学选择性涂层引起的近红外反射率的组合令人惊奇地导致在约800至约约的光谱范围内非常好地抑制来自PDP的IR发射 2500 nm和色度增强,同时保持良好的透光率。
