Researchers build 3D TVs using quantum dots and DNA structures

Researchers from the Massachusetts Institute of Technology (MIT) want to build a 3D television based on DNA structures and quantum dots. This could lead to even narrower displays.

The next step in the further development of computers is imminent. Because quantum computers will soon replace classic systems. Current systems are again based on the presence of a voltage. Current either flows (reflecting a “1”) or not (reflecting a zero). Quantum computers, on the other hand, can map both states in one bit and therefore require significantly less memory for the same amount of operations.

So far, however, the technology has mostly only been used in large companies and research institutes. But now researchers from MIT have brought a flat screen into play that is supposed to display content on the basis of so-called quantum rods in 3D. Previously, only simple points were possible that allowed the unstructured rendering of two-dimensional content.

3D TV based on DNA scaffolds and quantum dots

This is made possible by using a DNA scaffold. For the past 15 years, a team has been dedicated to the production of nanostructures from the biological material. This approach, known as DNA origami, is very stable and is an ideal building material for nanoscale applications. For this purpose, a research team also developed a computer-aided application that spits out the appropriate instructions for every requirement.

The scientists at MIT now used these research results to position quantum dots. They made diamond-shaped DNA structures and placed the dots on them. The approach makes it possible to keep the right distances and align in the right direction.

Possible areas of application in the production of AR/VR headsets

The researchers hope that this will make it possible to produce so-called wafers (large plates). If successful, the technology could produce screens that are significantly more compact and lighter.

Possible areas of application would be displays for virtual reality and augmented reality headsets. But the technology should also play an important role in future smartphone generations. Because when screen components become smaller, power consumption also decreases and manufacturers have more leeway to integrate new components.
