Microsoft has filed a patent application for displays that can change shape to make three-dimensional representations of objects.
Display screens would shift shape in response to light stimuli.
"A light-induced shape-memory polymer display screen is provided herein," said the application. "One example display device includes a display screen having a topography-changing layer including a light-induced shape-memory polymer."
The invention, by Microsoft researcher Erez Kikin-Gil, is for a display screen with underlying polymers that change shape when subjected to light at different points on the spectrum. The polymers are smart materials which can distort, hold their shape, and reform.
The application covers different displays, and includes a touchscreen display.
