    摘要: A plasma display panel (PDP) includes an EMI filter at a front portion thereof for blocking/shielding substantial amounts of electromagnetic waves. The filters has high visible transmission, and is capable of blocking/shielding electromagnetic waves. In certain example embodiments, a silver based coating of the EMI filter reduces damage from EMI radiation through highly conductive Ag layers, blocks significant amounts of NIR and IR radiation from outdoor sunlight to reduce PDP panel temperature, and enhances contrast ratio through reduced reflection, while maintaining high visible transmission. In certain example embodiments, at least one layer of or including silicon nitride may be Si-rich, and/or at least one layer including an oxide of Ni and/or Cr may be a suboxide, in order to improve heat treatability of the coated article.
