World's smallest pixels may help create building-sized flexible displays

Updated: few hours ago

London, May 13 (PTI) Scientists have created the world's smallest pixels, by trapping particles of light under tiny rocks of gold, that could be used for new types of large-scale flexible displays, big enough to cover entire buildings.

The colour pixels, developed by scientists from the University of Cambridge in the UK, are compatible with roll-to-roll fabrication on flexible plastic films, dramatically reducing their production cost.

It has been a long-held dream to mimic the colour-changing skin of octopus or squid, allowing people or objects to disappear into the natural background.

However, making large-area flexible display screens is still prohibitively expensive because they are constructed from highly precise multiple layers.
