基于荫罩式PDP新型十字扫描电极放大单元的研究

Study of a Novel Cross Scan Electrode by Macro-Cell Based on Shadon Mask PDP

新型荫罩式等离子体显示板利用制造工艺成熟的金属荫罩替代复杂的介质障壁,不仅降低了成本、而且改善了性能。为了进一步提高其亮度和效率,针对42inch荫罩式等离子显示器提出了一种新型十字形扫描电极结构,采用放大单元实验方法,研究了该电极结构的放电过程,给出了高速ICCD拍摄的光分布图。测量了相应的功耗、红外辐射强度、以及放电效率,并与传统条状电极结构进行了比较。结果表明,新型十字形扫描电极结构使放电区域沿扫描电极的主电极部分大大扩展,放电更剧烈,亮度也有显著提高,效率得到了改善,放电速度也更快。

Different from the common PDP, the complex barrier ribs are instead by shadow mask in Shadow mask PDP （SMPDP）, so the cost has been reduced and the performance has been improved. In order to enhance the luminance and efficacy further, we proposed a novel cross scan electrode based on the 42 inch SMPDP with diamond cell configuration. The macro-cell is used to investigate the discharge process of the novel electrode and the radiation figures obtained with ICCD are given. The power consumption, infrared radiation and discharge efficacy has been measured and compared with the conventional strip electrode. The results show that the novel cross electrode configuration has made the discharge area spread further along the cross electrode and enhanced the intensity of discharge. At the same time, the luminance and efficacy has been increased and the discharge became more faster with the novel cross electrode.
