The new insertion method of liquid powders using the electrode array for e-paper applications

In this paper, the new particle insertion method was proposed and experimentally demonstrated. In the proposed method, the electrode array was adopted to insert the liquid powders into each cell of the liquid powder display panel. The each electrode pattern size was 140 times 140 mum and the size of the electrode pattern array was fabricated on the glass wafer. The each square cell size of the base panel was 220 times 220 mum and the width of the rib on the panel was 20 mum. The voltage range applied to the electrode array was about from 0 to 600 V DC. To monitor the operation characteristics of the liquid powder under the various applied voltage conditions, the computer vision system was also used. The experimental results showed the strong capability of the noble method to manipulate the charged tiny particles for the mass production applications of the e-paper.
