Outstanding Venture Award for Smart Color-Changing Windows

Outstanding Venture Award for Smart Color-Changing Windows

The color of the windows can be changed at any time through the remote control of a mobile app. Lin Tsung-Hsien, a distinguished professor in the Department of Photonics, teamed up with the Liquid Crystal Photonics Lab students and spent more than a year to develop a film that could attach to the glass. Through the mobile app, a touch on the screen of the phone can alternate the glass between blurred, light, and dark colors as well as convert it into a projector at any time. In the future, the film could be applied to vehicles and commercial buildings. This innovative invention was distinctive among the 166 enlistments from new team members and won the Outstanding Venture Award from the Ministry of Science and Technology, with a prize valued at NT$2 million. This product can be used in  a variety of situations. In vehicles for example, the glass can be switched to a heat-insulating state during the day to block the glare of light and heat, and to a transparent state in the evening to provide a clear view while driving. When applied to architectural glass, users can actively control the light flux inside the room, and switch to a state of black fog at night to ensure privacy. The multifuntional smart window can be uesd with projection equipment to present high-quality images on the glass, thus improving the experience of augmented reality.
