LG Electronics will begin the development of handsets with energy-efficient displays based on Qualcomm’s mirasol MEMS technology. Qualcomm said tis nature-inspired mirasol display consumes significantly less power than other display technologies, extending handset battery life and enabling consumers to enjoy greater mobility. 
The display works by reflecting light so that specific wavelengths interfere with each other to create color. The phenomenon that makes a butterfly’s wings shimmer is the same principle used in Qualcomm’s mirasol displays.
