The best-performing dots today emit light with over 99 percent efficiency. When combined with the efficiency gains that come with removing the filter, these dots can create a picture as much as twice as bright as today’s LCDs with twice the efficiency. This display also has a wide viewing angle because the quantum dots sit at the front of the screen and emit light in all directions.

Don’t expect to see electro-emissive quantum-dot displays in stores in the next couple of years—they’re still in the early phases of development. However, they’re moving along quickly: Chinese display maker BOE Technology Group Co. demonstrated the technology publicly for the first time in 2017. The first commercial displays using the technology should start rolling out of factories in the next five years.
