Novel Cyanoethyl Cellulose-based Bilayer Materials for Electrowetting Displays at Low Voltage.

Electrowetting displays (EWD) still face the challenge of high driving voltages, provided by specialized driver ICs for electrowetting technologies. However, if the driving voltage is reduced to the threshold of widely used driver ICs of liquid crystal displays, it would significantly accelerate the revolution of driving ICs for EWD devices. Cyanoethyl cellulose (CEC) is utilized as a novel dielectric layer for electrowetting-on-dielectric systems and shows a large contact angle modulation, enabling low-voltage-driven wettability and device operation.
