【摘要】 介绍了一套简单、低成本的制作二极管型碳基膜场发射显示器模块的制作方法。该显示单元模块为16*16矩阵型点阵,可根据实际需要拼接成各种尺寸。器件的阴极和阳极均采用丝网印刷技术,包括:阴极导电图形、CNT图形、阳极荧光图形的印刷。各膜层图形经过精心设计以实现矩阵选址。使用低玻粉将阴极和阳极烧结之后,采用超高真空排气台进行排气,然后装配上驱动电路,即实现了单元碳基膜场发射显示器模块的制作。另外,为了改善CRT荧光粉的黏附性差和电阻率低的问题,我们往CRT荧光粉浆料中分别加入了碳纳米管和硝酸镁,得到了更好的发光性能。更多还原

【Abstract】 The paper introduces a simple and low-cost process for fabricating diode-type field emission display unit with 16×16 matrix arrays of pixel.Screen printing technology is adopted to prepare carbon nanotubes(CNTs) cathode and phosphor anode,including silver electrodes as the cathode conductive layer,CNTs layer,and phosphor layer.The patterns of above-mentioned layers were all designed elaborately to realize 16×16 matrix addressing.Glass firt was used during sealing the CNT cathode and phosphor anode.After gas exhaustion by ultra-high vacuum exhaust station and assembly of driving circuit,a 16×16 matrix-addressable diode CNT-FED module was achieved.And it’s easy to realize the fabrication of different sizes FED by jointing corresponding modules.Furthermore,in order to improve the weak adhesion and low conductivity of phosphor,proper CNTs and magnesium nitrate(Mg(NO3)2) were added respectively to phosphor paste before screen printed,and both resulting better display quality.更多还原
