Developed at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), the device works like a simple stamp. You upload an image, place the device on a surface, and it applies the design without complicated setup or modeling.
How ChromoLCD uses light to redesign real world objects
At the core of ChromoLCD is a mix of LCD technology and LED lighting. The system first maps an image in black and white, then uses ultraviolet light to activate photochromic dye on the surface. After that, red, green, and blue light layers in color and
