“…10 shows the most important energy levels and transitions for Xe. The generation of the Xe excitation states Xe*(1s 4 ) and Xe*(1s 5 ) include three kinds of processes: 21,25 (1) electron impact excitation directly from the ground state (shown by the gray arrows); (2) heavy body collisions with Xe**(2p 5-10 ), Xe*(1s 2 ), or Xe*(1s 3 ) by the Ne or Xe atoms (shown by the magenta arrows); (3) radiative processes by Xe**(2p [1][2][3][4] or Xe**(2p 5-10 ) (shown by the green arrows). The processes related to NIR and VUV radiation, which are concerned with in this section, are marked in the diagram.…”

“…INTRODUCTION Recently, the improvement of luminous efficacy in the PDPs towards the goal of "5 lm/W" is achieved by using various advanced technologies. [1][2][3][4][5][6][7][8] However, comparing with the fluorescent lamp that is able to reach the luminous efficacy of 60 lm/W, the gap in plasma display panel (PDP) is still huge. This becomes especially clear when observing the difference in the VUV production efficiency: compared with the other VUV emitting plasma devices, like the fluorescent lamps, the small discharge space of PDP limits the VUV production efficiency of PDP to a level of only 0.1, compared with about 0.6 for a fluorescent lamp.…”

In this work, the effect of the Xe partial pressure on the excimer vacuum ultraviolet (VUV) emission intensity of the plasma display panels is investigated, both by measuring the spectral emission directly and by two-dimensional simulations. Experimentally, we find that at the high Xe partial pressure levels, there is an supra-linear increase of excimer VUV radiation and that determines the strong increase of luminance at the high pressures and high voltage. Due to the increase of the luminance and the almost unchanged discharge current, the luminous efficacy strongly increases with the Xe partial pressure. In addition, we also investigated the dynamics of the VUV generation, by measuring the decay time of the excimer VUV light as a function of the gas pressure. It is found that the decay time decreases with the increase of gas pressure. The spatial characteristics of the excimer VUV emission are also discussed. Different from the Ne and near-infrared emission, the excimer VUV emission is generated near the surface of the electrodes and increases uniformly on both sides of the anode and cathode (i.e., the bulk plasma region). Most importantly, it is found that the VUV production occurs during the afterglow period, while it is almost zero at the moment of the discharge itself. From the simulations, it can be seen that the Xe2*(3Σu+) excimer species, which are generated from Xe*(1s5), play a dominant role in the excimer VUV emission output at the high Xe partial pressure. The two-dimensional simulations also show that the strong increase of Xe excimer excitation states in the case of high pressure is mainly the result of the high conversion efficiency of the Xe excimer states, especially in the afterglow period. Due to the high conversion efficiency of Xe excitation species to Xe excimer species by the high collision rate in the case of high pressure, there is a strong increase of excimer VUV production, especially from the cathode.

A new sustainer with primary-side integration of DC/DC converters and energy recovery(SPIDER) circuits is proposed. The proposed circuit operates as a DC-DC converter during address period and energy recovery circuit during sustain period. Therefore, the conventional three electronic circuits composed of the power supply, X-driver, and Y-driver can be reduced to one circuit. As a result, it has desirable advantages such as a simple structure, less mass, fewer devices and cost reduction. Moreover, since the Zero Voltage Switching (ZVS) of all power switches can be guaranteed, a switching loss can be considerably decreased. To confirm the operation, validity, and features of the proposed circuit, experimental results from a prototype for 42-inch PDP are presented.

“…Both PDP and FED have higher brightness and greater response than an LCD. However, they have high fabrication costs and lower yields, especially for large panels, because of difficulties in forming fluorescent coatings [6]. The fabrication of a fluorescence layer involves applying a fluorescent paste, solvent drying, exposure, development, and heat treatment.…”

A new paste and fabrication procedure for forming stable fluorescent layers on flat panel displays formation is discussed. We have characterized the uniformity and thickness of the fluorescent paste and, using simulations, have found that the optimum fabrication conditions are with a paste sectional area of 2050 lm 2 , a dispenser pressure of 0.5 MPa, a nozzle gap of 30 lm, and nozzle inner diameter of 0.14 mm. In addition, a contact angle of 0°is the optimum surface of the glass substrate, supporting a heat-treated black matrix. The finished layer has a uniform thickness of 13.9 ± 1.1 lm, and a thickness/width aspect ratio of 0.1. The new method can form uniform 8 ± 1.5-lmthick fluorescent layers at each opening in the black matrix; it reduces contamination, and can be extended to large substrates.
