“…5) One of the most critical issues in current photonic devices is the improvement of the luminous efficiency and/or discharge efficiency. There have been several approaches so far for the optimization of cell structures in the field of plasma display panels (PDPs), such as a structure with a grooved dielectric layer between the electrodes, [6][7][8][9] a structure with vertically raised bus electrodes, 10) a structure with a long electrode gap, 11) a structure with a delta array of discharge cells, 12) and a structure with horizontal counter electrodes. 13) In the photonic device field, new structures fabricated on semiconductor, ceramic, and multilayer metal/ polymer substrates have been developed, 14,15) which have cross-sectional dimensions much smaller than those of current PDP cells.…”

The present paper describes a three-dimensional (3D) thick-photoresist microstructuring technique that exploits the effect of exposure wavelength on dissolution rate distributions in a thick-film diazonaphthoquinone (DNQ) photoresist. In fabricating 3D microstructure with specific applications, it is important to control the spatial dissolution rate distribution in the photoresist layer, since the lithographic performance for 3D microstructuring is largely determined by the details of the dissolution property. To achieve this goal, the effect of exposure wavelength on dissolution rate distributions was applied for 3D microstructuring. The parametric experimental results demonstrated (1) the advantages of the fabrication technique for 3D microstructuring and (2) the necessity of a dedicated simulation approach based on the measured thick-photoresist property for further verification. Thus, a simple and practical photolithography simulation model that makes use of the Fresnel diffraction theory and an empirically characterized DNQ photoresist property was adopted. Simulations revealed good quantitative agreement between the photoresist development profiles of the standard photolithography and the moving-mask UV lithography process. The simulation and experimental results conclude that the g-line (λ = 436 nm) process can reduce the dimensional limitation or complexity of the photolithography process for the 3D microstructuring which leads to nanoscale microstructuring.

“…There were some examples in which the high electric field was achieved by the modification of cell design. 10,31,32 However, those designs are not easy to apply in real PDPs because of the complication in fabrication. Figure 4 shows the change in E/p distribution with time for each case.…”

“…It is well known that high luminous efficacy can be achieved if the number of excited particles is increased by increasing the Xe partial pressure, 2-4 by increasing the gap distance between electrodes, [5][6][7] or by developing a new design for the shape of electrodes or dielectrics. [8][9][10][11][12][13][14] Each of the above mentioned solutions has its own drawback. Increasing the gap distance between the electrodes or increasing the partial pressure of Xe requires a high driving voltage.…”

The results of a two-dimensional fluid simulation of a plasma display panel (PDP) cell show that the discharge characteristics of a coplanar dielectric barrier discharge can be controlled by the electrode tilt angle rather than by the gas mixture ratio or gap distance. The change in the tilt angle results in a significant change in the wall charge distribution and the discharge duration for each pulse. Therefore, the breakdown voltage, plasma density, light brightness, and luminous efficacy can be controlled by the tilt angle. A concave electrode structure allows large wall charge accumulation near the outer edge of two coplanar electrodes, and it results in a long-duration discharge, high luminance, and high luminous efficacy. On the other hand, a convex electrode structure allows high wall charge accumulation near the gap between two coplanar electrodes, and it results in a short-duration discharge with a decreased breakdown voltage.

The effects of total pressure and Xe partial pressure on the characteristics of an alternating-current plasma display panel with a two-opposite-electrode discharge cell configuration and a three-electrode surface-discharge cell configuration were investigated in terms of the following electro-optical properties: breakdown voltage, sustain voltage, wall charge transfer curve, infrared emission characteristics, luminance and luminous efficacy. Despite the longer discharge gap length, the results of the experiment and three-dimensional plasma simulation indicated that the opposite-discharge configuration has a significantly lower breakdown voltage than the surface-discharge configuration. Furthermore, the ratio of the increase in the breakdown voltage for the opposite-discharge configuration to the incremental Xe partial pressure was found to be smaller than that of the surface-discharge configuration. Because of its low driving voltage and possible use of high-Xe partial pressure, the opposite-discharge mode exhibited a higher luminous efficacy compared with the surface-discharge mode. These results indicated that the two-opposite-electrode discharge cell configuration has a cost reduction potential in electronics as well as high efficacy for plasma displays.
