Abstract:
A display device comprising:a plurality of elongated compartments (30, 30â€², 30â€³) each containing an ionizable gas (33), walls of each of the compartments (30, 30â€², 30â€³) being provided with respective electrodes (31, 32) for selectively ionizing the ionizable gas (33) thereby forming a plasma discharge in the respective compartments during operation, each compartment defining a respective dimension of at least one pixel, an electro-optical layer (35) of an electro-optical material which, in response to application of a voltage across the material, attenuates transmitted or reflected light, and means for activating the electro-optical layer (35), characterized in that, to influence at least one of the ignition characteristics, sustain current characteristics, and afterglow characteristics of the plasma discharge, the ionizable gas (33) comprises a carrier gas and an additional gas comprising, a gas selected from the group consisting of deuterium and deuterium hydrogen.
