In a crucial step in the development of color quantum-dot displays, QD Vision is developing rubber stamps to deposit quantum dots–tiny light-emitting crystals–on a surface.

The technique lets them put rows of different-colored dots next to each other, allowing for displays that promise to be thinner, more flexible, brighter, sharper, and more power efficient than flat-panel LCDs.

Affordable displays based on the technique could be on the market as soon as 2011.
