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 ...

If you remember old computer magazines (or browse them today), you’ll see that back in the late 1970s and early 1980s, you weren’t always sure what you were going to do with a computer. Games were a ...

An LED 3D printer at Princeton has integrated quantum dot LEDs with a standard contact lens to create a device capable of projecting beams of coloured light. Essentially, an artificial eye. Though not ...

While you can get an LED matrix in any size or shape, the really cool looking ones that are perfect for low-res displays all have diffusors. When they come from a nameless Chinese factory, these ...

After more than two years and an estimated $20,000, a research group in the mechanical engineering department has created the first 3D printer capable of printing LED lights. The venture was led by ...

Researchers at Graz University of Technology have created a new type of 3D printer that uses LED instead of laser sources for additive manufacturing of metal parts. The new 3D printer can optimize 3D ...

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 ...
