The luminous efficiency improvement is a key issue for making a plasma display into a large flat panel device. We suggest a new combination of a three-component gas, Ne–Xe–Ar, to achieve a high luminous efficiency of a color plasma display panel. The densities of 26 species and the electron temperature were calculated by zero-dimensional simulation, and we compared the results of zero-dimensional simulation with a measurement of vacuum ultraviolet (VUV) intensity covering a 140–180 nm wavelength range, in order to find the optimum mixing condition of Ne–Xe–Ar gas in a color plasma display panel. Reaction mechanism was analyzed by a computational work to comprehend the mechanism of discharge in Ne–Xe–Ar as well as Ne–Xe. The maximum peak point of the Xe*(1S4) state was obtained in 0.5% of Ar mixing ratio by simulation and the maximum luminous efficiency was measured at the same point of 0.5% Ar mixing ratio in VUV measurement. The luminous efficiency has been improved considerably (about 30%) with a 0.5% Ar addition, compared with the Ne–4% Xe mixing gas.

Accordingly, a new combination of a four-component gas, He-Ne-Xe-Ar, is proposed in order to achieve a high luminous efficiency in color plasma display panels ͑PDP͒. The densities of 32 species and electron temperature were calculated using a zero-dimensional simulation. The results were then compared with measurements of brightness and luminous efficiency to identify the optimum mixing condition of He͑7͒: Ne͑3͒-Xe͑4%͒-Ar gas for a color PDP. The reaction mechanism was computationally analyzed to comprehend the discharge mechanism in He-Ne-Xe-Ar as well as in He-Ne-Xe. By simulation, the maximum peak point of the Xe*( 1 S 4 ) state was obtained between a 0.1% and 0.5% Ar mixing ratio and the maximum luminous efficiency was measured with a 0.3% Ar mixing ratio in the PDP. As a result, the luminous efficiency was considerably improved ͑about 20%͒ with a 0.3% Ar addition, compared with the conventional He-Ne-4% Xe mixing gas.
