US Patent 7492101 - Multicolor plasma display with CNT layers

http://www.freepatentsonline.com/7492101.html

This patent from Samsung SDI discloses a plasma display in which a layer of carbon nanotubes is placed above the color fluorescent material to provide improved luminous efficiency. Claim 1 reads:

1. A plasma display panel (PDP), comprising:

a lower substrate;

a dielectric layer formed on the lower substrate;

partitions formed along a first direction on the dielectric layer;

red, green, and blue discharge cells defined by the partitions; and

a red, green, and blue fluorescent layer formed in the red, green, and blue discharge cells, respectively; wherein

a carbon nanotube (CNT) layer extends along the first direction and completely covers the red, green, or blue fluorescent layer.
