The The light output of dipole source in three types of light-emitting diodes (LEDs), including the conventional planar LED, the nanorod LED, and the localized surface plasmon (LSP) assisted LED by inserting silver nanoparticles in the gaps between nanorods, was studied by use of two-dimensional finite difference time domain method.

Again, uLED beats QD-LED/LCD on performance but loses massively on cost, and QNED is unlikely to surpass QD-LED/LCD on brightness, so it’ll come down to how it competes on cost while delivering perfect blacks (meaning a challenge, it’s probably going to have to be cheaper than QD-LED/LCD to take market share from the Bright Lover crowd). 2021-01-17 · Mini-LED, on the other hand, improves on the existing LCDs by replacing their LED backlights with mini-LED backlights, which consist of more efficient and numerous light-emitting diodes that will increase contrast ratio, uniformity, response time, etc.
