“…Some part of the above three-body processes may produce Xe 2 (0 u ϩ ) at higher vibrational levels, which lead to the 152 nm band emission. 17 However, from the observed spectra in the VUV region in usual cases, 18 the wavelength-integrated intensity of the 152 nm band is estimated to be less than 10% to 20% of the intensity of the 173 nm band. There included also is the contribution from Xe(1s 4 ) atoms to the 152 nm band emission as described below.…”

Two-dimensional spatiotemporal behaviors of excited Xe atoms in the 1s 4 resonance state and the 1s 5 metastable state were measured in a unit discharge cell of an ac-type plasma display panel by a laser absorption technique combined with an optical microscope. The measured density of Xe(1s 5 ) has two large peaks on both the temporal anode and cathode sides. The peak at the anode has a narrower spatial distribution while the peak at the cathode is distributed over the electrode area. In its temporal behavior, the anode peak rises slightly faster than the peak at the cathode and decays faster at the beginning of afterglow, but both peaks tend to have the same decay rate in the later period. The behavior of Xe(1s 4 ) shows similar features, but the decay rate is much larger, corresponding to the effective lifetime of imprisoned resonance radiation. The maximum densities of Xe(1s 5 ) and Xe(1s 4 ) are 5ϫ10 13 and 2ϫ10 13 cm Ϫ3 , respectively. Emission from Xe(2p) atoms was also observed, and this nearly followed the current wave form. With these results, we estimated the efficiency of vacuum ultraviolet emissions from excited Xe(1s 4 ) atoms and Xe 2 * excimers formed from Xe(1s 5 ) atoms.

We have studied the effects of ternary gas mixtures of Xe͑10%͒-Kr͑20% and 40%͒-Ne on the luminous efficiency in ac plasma display panels. Spatiotemporal behaviors of near infrared ͑IR͒ emission was measured by an intensified charge-coupled device camera equipped with a narrow bandpass filter and absolute densities of excited Xe * and Kr * atoms in the lowest resonance ͑1s 4 ͒ and metastable ͑1s 5 ͒ levels were measured by a technique of microscopic laser absorption spectroscopy. We have found interesting features from both emission and absorption experiments, such as longer near-IR emission ͑0.3-0.4 s͒ and different temporal behaviors between the excited Kr * ͑1s 5 ͒ atoms and Xe * ͑1s 4 ,1s 5 ͒ atoms. We have also found that the order of magnitude of the peak density of excited Kr * ͑1s 5 ͒ atoms ͑ϳ10 12 cm −3 ͒ was ten times smaller than that of Xe * ͑1s 4 ,1s 5 ͒ atoms, and that their decay time was remarkably short ͑ϳ0.3 s͒. These results have then been compared with those for a binary gas mixture of Xe͑10%͒-Ne. At a certain range of the sustain voltage, the production rate of Xe * ͑1s 4 ,1s 5 ͒ atoms and the luminous efficiency have turned out to be slightly improved for the ternary gas mixtures, compared to the binary gas mixture.

We have developed a simple model of a bright-room contrast ratio (BRCR) measurement system for plasma display panels (PDPs) adopting a contrast enhancement film (CEF) by using an illumination design tool. Only four model parameters were used, namely, total ambient illumination power delivered by fluorescent lamps, a panel scattering rate, illuminance of PDP white patterns, and the absorption coefficient of a color adjusting film. These parameters were determined by simple optical measurements and matching simulations. The proposed model was employed to predict the BRCR values of four different CEF samples, and the simulated ones were found to be in agreement with measured ones within about 10% relative-error.
