Abstract
Improved plasma displays utilize electrodes including low electron affinity (LEA) materials such as diamond. In dc displays the LEA materials are disposed on the cathode. In ac displays the LEA materials are disposed on the dielectric layers of both electrodes. The improved displays exhibit reduced operating voltage, higher resolution, and enhanced robustness.
Claims13
In a plasma display comprising at least one plasma display cell, said cell comprising a pair of electrodes and walls separating said electrodes and enclosing a volume containing gas, comprising noble gas,
- the improvement wherein at least one of said electrodes comprises a low electron affinity material having an electron affinity less than 3 electron volts comprising a material selected from the group consisting of diamond, aluminum nitride, and aluminum gallium nitride.
