In this work, we propose the novel method to simply but precisely manipulate the hemispherical LC microdroplet array on a substrate through controlled nucleation and growth. Moreover, UV light irradiation on a photo-sensitive layer enables precise control of LC droplet location and size across the entire surface for pixelazation. The LC droplet arrays display scattered structural color that varies with the specific size of LC droplets.
