Abstract

image

Patterned photonic crystal (PC) domes with angle-independent photonic bandgaps are fabricated by inkjet printing droplets with controlled sliding three phase contact lines. Enhanced brightness over 40 times and a wide viewing-angle from 0° to 180° are easily achieved by incorporating fluorescent molecules into the PC domes, which is very desirable for display pixels. These results will be of great significance for the development of flexible, wide viewing-angle displays.
