Isamu Akasaki and Hiroshi Amano of Japan and US scientist Shuji Nakamura won the Nobel Prize in physics on Tuesday for the invention of blue light-emitting diodes, a breakthrough that spurred the development of LED technology used to light up computer screens and modern smartphones.
Blue light-emitting diodes help create the glowing screens of mobile phones, computers and TVs and promises to revolutionise the way the world lights its homes and offices.
The Nobel Prizes were given away at a glittering ceremony in Oslo, Norway. Here is a look at this year's winners.
Shuji Nakamura was given only a tiny bonus for his invention and he had to sue to get the money due him.
