Electrophoretic Deposition of Carbon Nanotubes Auxiliary Layer for Power Saving in AC Plasma Display Panels

The carbon nanotube (CNT) auxiliary layers are suggested to reduce the high driving voltage in ac plasma display panel (AC-PDP). The CNT layer, which was integrated on dielectric layer overlapping the PDP bus electrode, was formed by electrophoretic deposition without sheltering further plasma emission light. The effective CNT pretreatment, uniform and thickness distribution of CNTs in the layer result in the excellent field-emission properties of low turn-on field (1.7 V/μm), which was proved to effectively reduce the discharge voltage of display cell with A-type (CNT layer is at the middle of indium-tin-oxide electrode) in a series of discharge testing. The lowest sustain volt- age for turning on the cells was reduced by 30-40 V. The FE-PDP theoretical model was proposed for explaining the testing results.
