Downscaling micro- and nano-perovskite LEDs

Downscaling micro- and nano-perovskite LEDs

Many technological breakthroughs in electronics and photonics were made possible by downscaling—the process of making elementary devices smaller in size1–5. The downsizing of light-emitting diodes (LEDs) based on III–V semiconductors led to micro-LEDs5–12, an ‘ultimate technology’ for displays. However, micro-LEDs are costly to produce and they exhibit severe efficiency losses when the pixel sizes are reduced to about 10 μm or less, hindering th…

University Team Creates World’s Smallest LED

PeLEDs are an emerging class of light sources that can be used in displays, lighting, and communications.

New LED displays packing 90nm 'virus-sized' pixels can deliver 127,000 PPI visuals

Researchers have created pixels that are as small as a virus, enabling display densities up to 127,000 PPI.

Oh yes, China and viruses, they are the most breathtaking inventions in the world! Chinese physicists, engineers, opticians and photonics specialists from Zhejiang University in Hangzhou, China, have developed pixels the size of a virus. These pixels have been used to create a display that is being called the world's smallest light-emitting diode (LED) array. With the help of colleagues from the University of Cambridge...
