When these particles are exposed to stimuli from different electrical fields, different aggregate shapes are produced, displaying a white or black effect. (It is possible that black and white particles could be altered into other hues, but the technology for this is not yet ripe.)
這些粒子受到不同電場驅動時，會產生不同的群聚狀態，可藉此顯示出或黑或白的效果；如果將黑白粒子改為其他顏色，也可以呈現彩色畫面，只是目前技術還不成熟。
