MIT Researchers Develop Reprogrammable Photochromic Display

MIT CSAIL researchers have developed ChromoLCD, a portable device that programs photochromic-dyed surfaces by combining an LCD panel with UV and RGB LEDs, and will present the paper at the ACM International Conference on Tangible, Embedded, and Embodied Interaction. The system stamps designs onto textiles, walls, and whiteboards in about 15 minutes via Bluetooth or USB, enabling reprogrammable apparel, AR tags, and interactive surfaces.
