Colloidal quantum dot laser diodes are just around the corner

Los Alamos scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as lasers. These ...

Photoluminescent display absorbs, converts light into energy

By replacing the phosphor screen in a laser phosphor display (LPD) with a luminescent solar concentrator (LSC), one can harvest energy from ambient light as well as display high-resolution images. "Energy-harvesting laser ...

Huge 3D displays without 3D glasses

A new kind of display uses laser beams to send out different pictures into different directions. Each pixel contains lasers and a moving mirror, which directs the laser light. Different pictures can be sent to the right and ...
