Field emission was proposed as an auxiliary application of the PDP flat panel display. The CNT auxiliary electrode sample prepared was subjected to Performance evaluation. In this paper, the macro-scale and micro-morphology of the CNT auxiliary electrode during the process are characterized by three-dimensional contour and SEM micrographs. The dispersion of the system directly related to its properties was characterized by Raman spectroscopy, Fourier transform infrared spectroscopy, particle size distribution and ZETA potentials. Optimized electrophoresis parameters were obtained through systematic analysis and optimization of charged salt concentration, electrophoresis voltage, electrophoresis time and the distance between cathode and anode. By comparing the key parameters to determine the process before and after the treatment and its effect. The field emission performance of the CNT auxiliary electrode was tested to evaluate its auxiliary performance and to investigate its compatibility with the PDP unit preparation process. The CNT assisted electrode field emission turn-on voltage of the optimized process was as low as 1.2 V / μm at a current density of 10 μA / cm2. Although it is increased to 1.6 V / μm after the preparation of the MgO protective layer, it can still guarantee its typical function as a PDP auxiliary electrode. The established method for preparing the CNT auxiliary electrode has good compatibility with the preparation process of the PDP display unit.
