Electro-wetting displays

We show that a novel effect, electro wetting, can be the basis of passive displays which (i) switch reversibly from transparent to white, (ii) have fast response time (<1.0 ms),and (iii) can be operated with low voltages (<1.0 V) and low power consumption (<1.0 mW/cm2). We derive the operating parameters and report experiments demonstrating the concept of electro-wetting displays.
