项目摘要

Through this research, we developed multi-color flat discharge panels by using negative glow (barrier) discharge which was based on the principle of the color controlled dischage, and also developed turn on circuits for them.(1) Flat discharge panel with ITO and Al foil outer electrodes and Xe gas 8 or 15.7 Torr enclosedWe painted red and blue fluorescent materials on inner walls of the opposite glass plate of the flat panel, and we got 450nt in maximum brightness and (0.16,0.13) - (0.64,0.35) in CIE-xy chromaticity by using booster transformer circuits. In this case, the discharge voltage was high according to the thickness of the glass wall.(2) Flat discharge panel with ITO and Al foil outer electrodes and Ne/Xe mixed gas 747 Torr enclosedWarm-white and blue fluorescent materials were used. We got (0.14,0.06) and 1000nt- (0.45,0.41) and 5200nt by using full-bridge switching circuit in addition to transformer circuit. The maximum value of brightness was about 8000nt at the center of a panel, and the mean value was about 4000nt. But, in this case, the discharge voltage was over lkV,and the destribution of brightness was not uniform.(3) Flat discharge panel with ITO and metalized inner electrodes (dielectric coating)On the Hg/Xe enclosed panel, because of unevenness of ITO transparent electrodes, we were not able to turn on color controlled discharge. The Ne/Xe enclosed panel was broken by radiant heat of negative glow. But inner electrodes method was very effective to lower the discharge voltage.Turn on circuitIt was effective to increase the brightness that we increased a peek current by using full-bridge rectangular switching.

通过本课题的研究，我们利用基于色控放电原理的负辉光（阻挡）放电，研制出多色平板放电板，并研制出相应的开启电路。(1)采用ITO和Al箔外电极、8或15.7Torr氩气保护的平板放电屏在平板对面玻璃板内壁涂上红、蓝荧光材料，采用升压Transformer电路，获得最大亮度450 nt，CIE-xy色度（0.16，0.13）~（0.64，0.35）。在这种情况下，放电电压根据玻璃壁的厚度而变高。(2)采用ITO和Al箔外电极、Ne/Ar混合气体747 Torr封闭的平板放电屏，使用暖白和蓝色荧光材料。采用全桥开关电路和Transformer电路，分别得到（0.14，0.06）、1000 nt-（0.45，0.41）和5200 nt。亮度的最大值约为8000 nt，平均值约为4000 nt。但是，在这种情况下，放电电压超过1 kV，并且亮度的分布不均匀。(3)具有ITO和金属化内电极（电介质涂层）的平面放电面板在Hg/Hg封闭的面板上，由于ITO透明电极的不均匀性，我们无法开启颜色控制放电。氖/氖封闭板被负辉光的辐射热破坏。而内电极法对降低放电电压非常有效。导通电路采用全桥矩形开关增加峰值电流对提高亮度有效。
