Abstract

Summary form only given. We have investigated the correlation between the secondary electron emission coefficient (gamma) of MgO protective layer and discharge luminous efficiency in alternating current plasma display panel (AC-PDP). We have fabricated the 4 inch PDP test panels with ITO gap distance of 60 mum, in which each PDP panel has respective their own secondary electron emission coefficient with Ne-Xe (15%) gas mixture. The MgO protective layer in PDP test panels has been deposited to be 7000 Aring by electron beam evaporation. Oxygen (O2) flowing rate has been changed for an each test panel during the MgO deposition. The secondary electron emission coefficient of MgO protective layers has been investigated by gamma-focused ion beam system (gamma-FIB) according to the respective O2 flowing rate. It is found that the secondary electron emission coefficient of MgO protective layer and discharge luminous efficiency are in strong correlation in this experiment.

交流等离子体显示面板(AC- PDP)中MgO保护层二次电子发射系数与发光效率的相关性

只提供摘要形式。研究了交流等离子体显示面板(AC-PDP)中MgO保护层的二次电子发射系数(gamma)与放电发光效率的关系。我们制作了ITO间隙距离为60 mum的4英寸PDP测试板，其中每个PDP面板在Ne-Xe(15%)气体混合物中各自具有自己的二次电子发射系数。采用电子束蒸发法制备了PDP测试板的MgO保护层，厚度可达7000 μ m。在MgO沉积过程中，每个测试面板的氧(O2)流速都发生了变化。利用γ聚焦离子束系统(γ - fib)研究了不同O2流速下MgO保护层的二次电子发射系数。实验发现，MgO保护层的二次电子发射系数与放电发光效率有很强的相关性。
