对钠钙平板玻璃进行切割形成后封装面板.结合高效的丝网印刷技术,在后封装面板上制作了半圆组阴栅结构.烧结的银浆层用于形成导电电极组中的双长条电极,而固化的绝缘浆料则用于构成绝缘层.碳纳米管直接制备在长条电极的表面,呈现双半圆形状,用于进行电子发射.栅极则是固定在碳纳米管阴极的上方,栅极和阴极之间依靠栅极基底而相互隔离.测试结果表明,应用半圆组阴栅结构,能够进一步降低阴极-栅极之间的电容效应,提高碳纳米管的电子发射能力,并增强三极场发射显示器的驱动灵活性.以碳纳米管作为阴极材料,进行了三极结构小型场发射显示器的研制.该三极显示器具有良好的场致发射特性,高的发光亮度以及优良的发光图像均匀度,其开启场强约为2.12 V/μm,且制作成本低廉.
