摘要

在电泳基电子纸中,研究了流体与带电粒子的比例是否会影响面板的反射率和流过面板的漂移电流。为此,本研究制作了三个面板,带电粒子与流体的比例分别为1:5、1:1和5:1。每个样品都使用相同的输入脉冲驱动,为此,在面板中流动的电流和光电二极管的输出电压被测量面板的反射率。因此,漂移电流最初呈现峰值,随后在一个点呈现饱和值。该值与带电粒子的比值成正比,大于1:1时与该比值相近。由于面板的反射率,光电二极管的输出电压与带电粒子的比例成正比。但是,当比例大于1:1时,响应速度下降。期望本研究结果将有助于电泳基电子纸中带电粒子的电荷分析,以及适当浓度的选择。

Current Properties and Evaluation of Electronic Ink in Electrophoretic Display
An investigation was conducted to determine whether the ratio of the fluid to the charged particles affects the panel reflexibility rate and the drifting current flowing in the panel, in electrophoretic-based electronic paper. In this regard, three panels were produced in this study with the ratio of the charged particles to the fluid set as 1:5, 1:1, and 5:1. Each sample was driven using an identical input pulse, for which the current flowing in the panel and the output voltage of the photodiode were measured for the panel reflexibility rate. Consequently, the drifting current initially exhibited a peak value and a saturated value at a later point. This value was proportional to the ratio of the charged particles, and it was similar to this ratio when it is higher than 1:1. The output voltage of the photodiode due to the panel reflexibility rate was proportional to the ratio of the charged particles. However, the response speed decreased if the ratio was higher than 1:1. It is expected that the results of this study will contribute to the analysis of the charging of charged particles in electrophoretic-based electronic paper, and the selection of an appropriate concentration.
