摘要
采用ANSYS有限元分析软件对平面栅型场致发射显示器(FED)的阴极表面电场进行了模拟分析。通过研究栅极宽度、阴栅间隙及阴极宽度对阴极表面电场分布的影响,结果表明平面栅型FED为边缘发射型器件,阴极宽度的改变对阴极表面电场整体影响明显,而阴栅间隙是影响阴极边缘电场分布的主要因素。
The ANSYS finite element computation program is used for the simulation of the surface Electric-field intensity distribution of the cathode of the planar-gate field emission display （FED）. With the study of the gate width, the gap between the gate and the cathode and the cathode width, it shows that the planar-gate FED is the edge emission device.The change of the cathode width can influence the surface electric-field intensity distribution of the whole cathode notibly, the most important factors upon the edge electric-field intensity distribution of the cathode is the gap between the gate and the cathode.
