Large-area display panels encounter voltage drops across the panel, which causes nonuniform light emission of their pixels. Such a voltage drop is due to the high sheet resistance of the transparent conductive electrode. A remedy to overcome the problem is to add assistive conductors between pixels so that the cross-panel resistance can be reduced. Electrohydrodynamic jet (EHJ) printing of silver ink has been investigated for its suitability to fabricate the assistive conductors. It was found that the high electric field in the EHJ printer could influence the characteristics of thin-film transistors (TFTs) of the backplane circuit, causing noticeable shifts in the threshold voltage due to the field-induced charge accumulation in the TFT semiconductor channel. A modified version of TFT was proposed and the influence of the electric field on the TFTs was greatly reduced.

显示背板电路中导体的电流体动力印刷研究

大面积显示面板在面板上遇到电压降，这会导致其像素的发光不均匀。这种电压降是由于透明导电电极的高薄层电阻引起的。解决该问题的一种补救方法是在像素之间添加辅助导体，以便可以降低跨面板电阻。已经研究了银墨水的电液喷射技术（EHJ）的适用性，以制造辅助导体。已经发现，EHJ打印机中的高电场会影响背板电路的薄膜晶体管（TFT）的特性，由于TFT半导体通道中的场致电荷积累，导致阈值电压发生明显变化。
