in Reference to Samsung, with an investment in branding "QLED":

Quantum dot TV tech works by placing a layer or film of quantum dots in front of a regular LED backlight panel. The layer is made up of tiny particles each of which emits its own individual colour depending on its size (anywhere between 2 and 10 nanometers). Basically, the size of the particle dictates the wavelength of light that it emits, hence the different colours. Samsung boasts that quantum dots enable over a billion colours.


BOE says in relation to QLED:


QLED stands for “Quantum Dot Light-Emitting Diode”. It has quantum film and its light-emitting layer is made of quantum dots instead of
phosphor as in conventional LED.


QLED is referring to different things depending on which company is talking.
