Abstract:
1. A plasma display device comprising: a plasma display panel (PDP); and an electromagnetic interference (EMI) filter provided at a front portion of the plasma display panel, the EMI filter including an EMI coating supported by a glass substrate, the EMI coating including layers moving away from the glass substrate including: a first high index layer having a refractive index (n) of at least about 2.2; a first silicon-inclusive layer; a first layer comprising zinc oxide; a first EMI shielding layer comprising silver contacting the first layer comprising zinc oxide; a first layer comprising an oxide of Ni and/or Cr contacting the first EMI shielding layer comprising silver; a first metal oxide layer; a second silicon-inclusive layer; a second layer comprising zinc oxide; a second EMI shielding layer comprising silver contacting the second layer comprising zinc oxide; a second layer comprising an oxide of Ni and/or Cr contacting the second EMI shielding layer comprising silver; a second metal oxide layer; a third silicon-inclusive layer; a third layer comprising zinc oxide; a third EMI shielding layer comprising silver contacting the third layer comprising zinc oxide; a third layer comprising an oxide of Ni and/or Cr contacting the third EMI shielding layer comprising silver; and a third metal oxide layer; a fourth silicon-inclusive layer; a fourth layer comprising zinc oxide; a fourth EMI shielding layer comprising silver contacting the third layer comprising zinc oxide; a fourth layer comprising an oxide of Ni and/or Cr contacting the third EMI shielding layer comprising silver, wherein the EMI filter has a sheet resistance of greater than about 1.2 ohms/square, and wherein thicknesses of both the first and fourth EMI shielding layers are less than thicknesses of the second and third EMI shielding layers.
