Breakthrough Digital Displays

Linköping University researchers have created a unique digital display screen. They enabled LEDs to react to touch, light, fingerprints, and the user’s pulse, without the need for any additional sensors.  The potential results could be a…

Nano-antennas and Photoluminescence

Will white LEDs lose their light source superiority? Seems so. A 2D photonic crystal or nano-antenna is a structure in which nano-sized particles are arranged periodically on a substrate. With irradiation, combining a nano-antenna with a …
