Abstract
A driving waveform based on the powder charge of a quick-response liquid-powder display (QR-LPD®) was investigated. The charging mechanisms for contact charging and triboelectric charging determine the powder charge of a QR-LPD®. In this letter, driving waveforms containing both charging mechanisms are used for driving a QR-LPD®. As the experimental results indicate, the charge of the powder accumulates according to the image refresh times. The waveform of a pixel voltage with a slight frictional charge achieves a better contrast ratio for a QR-LPD®.
