Message
1.	Electronic and photonic devices and their applications for image information systems Visualizing the invisible leads to discoveries and propels our understandings on nature. A beautiful picture takes our breath away. There is no need to reiterate the importance of electronic systems that handle images. Image sensors and displays are essential parts for human interfaces, contributing to the evolution of our social life of information. These devices are based on electronic and photonic materials, which also provide solid foundations for radiation detection, energy harvesting, and other important systems. This laboratory focuses on such materials, devices and systems. Our recent interests include a Luminous Reflective Display: by utilizing ambient light with luminescent materials, bright, vivid images are displayed.
