Display medium with particle manipulations in an emulsion droplet array

A self-assembled and packaged display medium is fabricated using microfluidic emulsion technology to encapsulated droplets of particles solutions in a curable continuous phase, which greatly simplifies the packaging process. After photo crosslinking, we obtain an emulsion droplet array of regularly and densely arranged droplets containing uniformly dispersed particles that are further addressable by the externally applied electric field to alter the reflectivity and perform as a display medium.
