​​What is Quantum Dot Technology?

A Quantum Dot is a human-made nanoparticle that has semiconductor properties. They’re tiny, ranging in size from two to 10 nanometers, with the size of the particle dictating the wavelength of light it emits, and therefore the color. When Quantum Dots are hit with a light source, each dot emits a color of a specific bandwidth: Larger dots emit light that is skewed toward red, and progressively smaller dots emit light that is skewed more toward green.
Quantum Dots are usually applied to a sheet of film that sits as a layer in that “sandwich” in front of the LED backlight that’s used to illuminate a Liquid Crystal Display (LCD). The light passes through the LCD display stack, with the Quantum Dot color filter layer enhancing and enabling the LCD to reveal a wider and more saturated range of colors than would otherwise be possible.
