The generation of multi-colors in plasma display panels has been obtained by the excitation of phosphors with the gas discharge. This excitation means has been either by the use of ultraviolet generated by the gas discharge or by direct electron excitation of the phosphors using the electrons generated in the plasma discharge. Ultraviolet excitation has been used with AC plasma panels, and the electron excitation with DC plasma devices. The use of ultraviolet for phosphor excitation necessitates the use of a gas mixture other than the conventional neon-argon, resulting in higher voltages, higher currents and crosstalk, requiring optical isolation of each cell, thereby complicating the cell topology.
