METHODS AND APPARATUS FOR PROVIDING A NEAR-IR EMISSION SUPPRESSING/COLOR ENHANCING ACCESSORY DEVICE FOR PLASMA DISPLAY PANELS

摘要

A method and apparatus for enhancing the performance of visual display units (52) which utilize plasma display panels (50) wherein the apparatus includes an electrical noise suppressing/chromaticity enhancing accessory device (10) for positioning in front of the viewing surface of a plasma display panel. The accessory device (10) includes a first and a second rigid substrate (30, 30') laminated together by a laminating layer (36), and an optically selective coating (22) providing high photopic transmittance, continuous high electrical conductivity for RFI shielding, and reflectivity specifically within the near-IR region. The laminated layer includes a multiple-dye coating for selectively absorbing IR energy emissions and selectively balancing the chromaticity of the plasma display panel.
