"Ever since 2015 Consumer Electronics Show, quantum dots have been in a market struggle to displace light-emitting diodes (LEDs) as a backlight source for liquid crystal displays (LCDs)."

'They have produced a LED pixel out of nanorods capable of both emitting and detecting light.

'“It’s very different from the use of quantum dots as backlight,” explained Moonsub Shim, a professor at the University of Illinois at Urbana–Champaign and co-author of the paper, in an interview with IEEE Spectrum. “In backlight displays you have white light that gets diffused into a plane and color filters create your red, green and blue pixels. But here the individual pixels would be these nanorods that would emit a specific color, so you wouldn’t need a backlight.”'
