利用等离子体显示板自发光、薄型、亮度高、发光均匀的特点,开发出基于等离子体显示机理的薄型等离子体面光源,用于需要薄型照明的特定场合.为克服等离子体显示板发光效率过低的不足,对面光源显示板的结构、材料,工艺和驱动电路诸方面进行多项改进,经改进后的等离子体面光源最小厚度不大于4 mm,亮度350 cd/m2,色温为 6500 K,发光效率4Lm/W.光源型 PDP 显示板的研究结果对进一步提高图象型 PDP 显示板的光电性能提供了有益的启示.%By using PDP (plasma display panel) characteristics of self-luminescence, thin structure, high brightness and uniform luminescence, a novel surface lamp-house based on PDP technology was developed to apply in a special space which needs thin illuminator. To overcome PDP'S shortage of low luminous ef- ficiency, many important modifications are accomplished in panel structure, phosphors material, working gas, manufacturing process and drive circuit. The improved surface lamp-house has parameters as follows.thickness less than 4 ram, luminance more than 350 cd/m2, color temperature 6500 K and luminous effi-ciency 4 lm/w. The study result of surface light source PDP will help to improve the photoelectric proper-ties of image PDP.
