Abstract
The luminous efficiency of the plasma display panel is investigated in terms of the xenon mole fraction. A theoretical model of the luminous efficiency in a mixed gas is developed, based on the energy balance equation. The luminous efficiency η is expressed as η=kχexp(−ɛ*/Tb), where χ is the gas mixture ratio, Tb is the electron breakdown temperature and ɛ* is the xenon excitation energy in eV. As an example, the luminous efficiency in neon gas mixed with xenon is investigated. It is shown that the luminous efficiency η increases monotonically as the xenon mole fraction increases from zero to unity. A preliminary experiment is carried out for neon gas mixed with a small percentage of xenon. The theoretical results agree reasonably well with experimental data. However, the efficiency enhancement dampens significantly when the xenon mole fraction is considerably large.
