What are Quantum Dots and How Do They Improve LEDs?
Quantum dots (QDs) are tiny semiconductor particles, typically ranging from 2 to 10 nanometers in size. They have unique optical properties due to quantum confinement effects, which cause them to emit light when excited by an external source. In LEDs, QDs can:
Provide tunable emission spectra, allowing for a wide range of colors. Improve color purity and saturation, enhancing display quality. Increase overall efficiency by converting more of the electrical energy into visible light.
