If you had an array of high power addressable LEDs, how would you project them onto a wall? Perhaps you’d use a Fresnel lens, or maybe an individual lens on the top of each. [Joo] faced this problem ...

Researchers at Princeton University have developed a 3D printer that can print LEDs in layers -- and it could one day print contact lenses that incorporate heads-up displays. Michelle Starr Science ...

Researchers at the University of Washington have created a contact lens with an LED display built into it. Whilst at present the contact lens device has only a single pixel of information, the ...

3D printing has captivated manufacturers worldwide and has truly revolutionized the future of our technological needs. Virtually any component can be realized; plastics, metals and even clear ...
