Infrared
drives flexible color display
The plastic display is made of molecules that absorb infrared light and transfer the energy to other molecules that emit the energy as visible light. This means the display can be driven by low-power infrared lasers, and the same light source can produce multiple colors.
The display can be refreshed thousands of times a second. It can be made virtually any size, and could be manufactured inexpensively.
