Abstract

Targeting the creation of magnetic twisting ball displays, we confirm the performance of a technology that partially coats white resin balls with a magnetic layer to form the contrasting black hemispheres. Control experiments verify that such balls can be magnetically driven and that power off steady state displays is possible by suspending the balls in a thixotropic fluid of appropriate viscosity. An experimental display sheet is prepared using the balls and thixotropic suspension fluid; rewriting and image holding performances are confirmed using a 3 by 5 driving unit with 15 electromagnets. The relations between driving pulse width and the display characteristics elucidate the minimum pulse width required for image switching.
