🤔 What Is This?

Quantum dots are tiny semiconductor nanocrystals, just 2-10 nanometers in diameter. Their extraordinary property: size determines color. Smaller dots emit blue light, larger ones emit red, with every color in between. This size-dependent emission arises from quantum confinement — when electrons are trapped in a space smaller than their natural wavelength, energy levels become discrete and tunable.

Why does this matter? QD displays (QLED, QD-OLED) produce the widest color gamuts in consumer electronics, exceeding 100% DCI-P3. By precisely controlling dot diameter during synthesis, manufacturers create displays with ultra-pure red, green, and blue sub-pixels — each with emission peaks as narrow as 25nm FWHM, far sharper than any phosphor or organic emitter.
