19‐1: A Novel Electrowetting‐based Display for Future Smart Window Application

Smart window is an emerging application for display industry. It can control the sunlight penetration and display information. In this paper, we had made 6-inch color smart window prototype by electrowetting-based technique. The ink jet process is adopted to dose various colored oil into sub-pixel to achieve color device. Without color filter, the transmittance of the device can be improved. Further, to evaluate the practicability of using the smart window device in the night, we had added luminescence substances into the colored oils and designed the cladding structure to achieve a luminous smart window.
