3D Photoactivatable Dye Displays for Visualization

We live in a colorful and complex 3D world, yet we communicate and represent data almost entirely on 2D displays like computer screens and paper. Traditional 3D displays (such as stereoscopic displays that require 3D glasses) do not generate actual three-dimensional images, but rely on tricking the eyes and brain to "appear" three-dimensional. While truly 3D "volumetric" display systems are being developed, they generally require moving parts, high power lasers for plasma generation or upconversion processes, complex light source arrays, or advanced multi-layered liquid crystal displays. These requirements all contribute to the expense of fabricating and operating such systems, making large-scale implementation impractical. As such, there is a need for fundamentally new 3D display technologies that are low cost and easy to implement. We have developed and disclosed a new type of volumetric 3D digital light photoactivatable dye display (3D Light PAD) that uses innovative photoswitch chemistry to generate high quality 3D images in a simple, inexpensive, and safe manner.
