Abstract

This paper describes a microfluidic-based multicolor reflective display using dyed water droplets as pixel elements. Our display was composed of a PDMS sheet with a connected pixel-patterned microchannel. Several types of water droplets and air gaps were sequentially introduced in the microchannel by sucking with a syringe pump to display . We evaluated the stability of minimum continuous number of water and air dots to display images correctly. We demonstrated displaying three colored dot-matrix reflective images. We believe that our display could be applicable to energy-less and color-changeable displays for future advertising signage or accessories including bags, shoes, or cloths.
