摘要
The power consumption and electric field distribution in a field emission display （FED） panel is optimized with a novel pixel structure. A circuit model is proposed to estimate the total power consumption in an FED panel which is composed of anode energy consumption, energy loss due to the leakage current and the energy dissipated in the parasitic capacitances. Moreover, the parasitic capacitances play a vital part in the power consumption and driving performance. In order to lower the parasitic capacitances, multiple dielectric layers are used as the gate electrode. Due to different etching speeds, a novel pixel structure is formed. As a result, the power consumption of an FED panel is reduced by 28% in a full white picture, and the electron beam performance is also better than that of the conventional structure.
为了降低场发射显示器的能量消耗,提出一种新型的像素点结构,并优化了其内部电场分布.基于此结构建立了一个电路模型,得到显示屏功耗的3个主要组成部分:阳极功耗、漏电流损耗和寄生电容能量损耗.其中寄生电容的存在不但会影响驱动电路性能,而且会增加显示屏的功耗.另外,利用多种绝缘层不同的腐蚀速度,得到了新型像素点结构,减小了显示屏的寄生电容,使得其功耗比传统结构减小了28%,并且发射电场分布也优于传统像素点结构.
