主 题：deformation reflective fluid
摘 要：Reflective displays have stimulated considerable interest because of their friendly readability and low energy ***,we develop a reflective display technique via an electro-microfluidic assembly of particles(eMAP)strategy whereby colored particles assemble into annular and planar structures inside a dyed water droplet to createopenandclosedstates of a display ***-in-oil droplets are compressed within microwells to form a pixel *** particles dispersed in droplets are driven by deformation-strengthened dielectrophoretic force to achieve fast and reversible motion and assemble into multiple *** eMAP based device can display designed information in three primary colors with≥170°viewing angle,~0.14 s switching time,and bistability with an optimized material *** proposed technique demonstrates the basis of a high-performance and energy-saving reflective display,and the display speed and color quality could be further improved by structure and material optimization;exhibiting a potential reflective display technology.
