Brace up for roll up TV as Researchers at Tel Aviv University have developed a novel structure that can be used to produce thin, transparent and flexible digital displays for TV sets, smartphones and tablets.
The television can easily be rolled up and put away, rather than requiring a flat surface for storage and transportation.
The technology harnesses bio-nanotechnology to emit a full range of colours in one pliable pixel layer as against the several rigid layers that constitute today’s screens.
The material is light, organic and environmentally friendly. It is flexible and a single layer emits the same range of light that requires several layers today.
By using only one layer, one can minimize production costs dramatically which will lead to lower prices for consumers as well, he added. For this, the researchers tested different combinations of peptides: short protein fragments, embedded with DNA elements which facilitate the self-assembly of a unique molecular architecture.
Peptides and DNA are two of the most basic building blocks of life.
In the field of bio-nanotechnology, scientists utilize these building blocks to develop novel technologies with properties not available for inorganic materials such as plastic and metal.
The researchers discovered that three of the molecules could self-assemble, in a few minutes, into ordered structures.
They found that structures emit light in every colour, as opposed to other fluorescent materials that shine only in one specific colour.
Moreover, light emission was observed also in response to electric voltage — which make it a perfect candidate for opto-electronic devices like display screens, the authors concluded.
