Abstract

We report a novel optical switch and display using fringing field-induced aperture change of a bracelet-like liquid ring. To prove concept, we demonstrated a 4x4 color pixel array and a black-and-white single pixel for an optical switch. Without an electric field, the pixel has the largest clear aperture. The applied fringing field stretches the liquid surface, leading to a decreased aperture size. For a 230-μm-diameter pixel, the switchable aperture ratio is over 80% and the response time is ~10 ms. This device has following advantages: polarization independence, fast response time, and easy fabrication.
