ABSTRACT:
To improve performance, reliability and lifetime of a plasma-containing electro-optic display device, at least the cathode electrodes have hollows or wells within which plasma discharge occurs. This reduces the tendency of the electrode material to be sputter deposited on the walls of the device. In addition, cathode emission is improved by incorporating emitter materials into the electrodes, either by alloying or by surface coatings.
