    Abstract

    We have developed new powder materials that exhibit liquid behavior, which can lead to the realization of novel bistable and reflective displays having paper-white appearance, high contrast, and quick response. Two types of display were demonstrated, one had 160 × 160 array of pixels and the other had 320 × 320 in a 3.1-in.-diagonal viewable image size corresponding to 66 and 132 dpi, respectively. These displays were driven by passive-matrix addressing. The displays showed a reflectivity of more than 41%, a contrast more than 1:10, and a pixel response time of less than 0.2 msec. The seven-segment display for use in clocks was also demonstrated.
