Abstract

A plasma display filter is formed to include an alternating pattern (12) of infrared blocking layers (22, 24 and 26) and ZTO (zinc oxide/tin oxide) dielectric layers (14, 16, 18 and 20). In one embodiment, the alternating pattern comprises four ZTO dielectric layers and three infrared blocking layers. Benefits of the plasma display filter are enhanced if the ZTO dielectric layers are sputter deposited in an environment which is intentionally hydrogenated. As another possible enhancement, a sacrificial layer or glue layer may be deposited over the infrared blocking layers prior to formation of the subsequent ZTO dielectric layer, so as to protect the underlying layer during formation of the ZTO dielectric layer. Suitable materials include titanium and nichrome. The chemical durability of the ZTO dielectric layers enables the omission of the conventional protective overcoat layer (28), if desired.
