Development of reflective paper-like display with triboelectrically charged-polymer particles

We have developed a paper-like display using polymer particles charged triboelectrically. By using a toner-type display with a simple structure, we confirmed that polymer particle movement is controlled by only a voltage difference between scan and data electrode. We fabricated a diagonal 2.4 inch panel on the glass substrate and successfully produced an image by the passive driving method with operating voltages of about ± 120 V. The contrast ratio was 4:1.
