The color of that light depends on the energy difference between the conductance band and the valence band , or the transition between discrete energy states when the band structure is no longer well-defined in QDs. And QLED monitors often deliver better technical performance than televisions with their added features such as sync technology and black level stabilization. For an exciton inside a quantum dot, there is also the Coulomb interaction between the negatively charged electron and the positively charged hole. So, it will only be a matter of time before QLED gaming monitors become a standard for all gamers. However, the specific colors vary depending on the exact composition of the QD. The folks making indium-based solutions like to paint cadmium as the bad guy Necessary Necessary. Retrieved 16 September When those blue LEDs shine on the quantum dots, the dots glow with the intensity of angry fireflies.
