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.
In order to reduce the energy consumption of the field emission display, a new type of pixel structure is proposed and its internal electric field distribution is optimized.Based on this structure, a circuit model is established and three main components of display power consumption are obtained: anode power dissipation , The leakage current loss and the parasitic capacitance energy loss.The existence of parasitic capacitance will not only affect the performance of the driving circuit, but also increase the power consumption of the display.In addition, the use of a variety of different insulating layer corrosion rate, a new pixel structure, Reduce the parasitic capacitance of the display, making its power consumption reduced by 28% than the traditional structure, and the emission electric field distribution is also superior to the traditional pixel structure.
