A billion colors and shades brought to life
Quantum dot size and color
Quantum dots are very small semiconductor particle, in the nanometer (nm) range, with unique optical and electrical properties that can be converted to energy. The electronic properties of quantum dots depend on size and shape: large quantum dots (5nm to 6 nm) emit long wavelengths such as red and orange,
while small quantum dots (2 nm to 3 nm) emit shorter wavelengths such as green and blue.
The video features Quantum dot size and colors. The Quantum dot core is consist of Core, Shell, Ligands and emits different wavelengths and color depend on the size and shape.
Ultimate benefits of quantum dot display
Quantum dot (QD) displays are devices that use these fluorescent semiconductor nanocrystals (a.k.a
quantum dots) as a part of panel architecture
to produce monochromatic light to deliver tunable
primary colors and increase screen efficiency and
performance. Quantum dot displays represent
innovative technology that can redefine the
performance capabilities for current displays. By
integrating quantum dots into a display,
Samsung Display (SDC) has enabled unmatched image
quality and optimized color performance. Take a closer
look at the amazing benefits of
quantum dot displays and the next generation of
products from Samsung Display.

Vibrant color with chromatic purity
Quantum dot displays provide the widest color gamut
of any existing display technology. Quantum Dots
displays can meet the BT2020 standard (73%)
as well as DCI-P3 (100%). Quantum dot technology can
mesmerize viewers with chromatic purity,
unmatched color volume (brightness and contrast) in
addition to vivid imagery.

100% color volume of delivering
more lifelike colors
Color volume refers to the range of colors that can be represented onscreen; higher the color volume, the
wider the actual range of color expression.
Samsung's Quantum Dot displays offer brings colors to
life, with an industry leading 100% color volume. This
100% color volume gives you vivid, life-like viewing experience for all your display needs
from movies to games.

Realistic and brilliant images with HDR
Adding the High Dynamic Range (HDR) feature to a quantum dot display lets you see all images in greater depth and clarity. The higher the peak luminance of
HDR, the brighter the screen gets, providing a more detailed view from the darkest to brightest parts of the screen, as well as improving depth and color accuracy to ensure amazing picture clarity.

Guarantee long lifespan without burn-in
"Burn-in" is a phenomenon in which a static image (text or graphics like a broadcast station logo) that remains on the screen for an extended period of time becomes permanently displayed. This burn-in problem can lead to ghost images or poor screen performance. However, quantum dots are an inorganic material with robust material properties that are not affected and can resist the burn-in issue.

Quantum dot core synthesis mainly uses cadmium selenide (CdSe) and indium phosphide (InP).
Cadmium-based QDs allow for the highest quantum efficiency but are toxic, and their use is regulated by RoHS. Samsung Display’s quantum dot displays are indium-based QDs, always safe and eco-friendly while engineered to perform for the most discerning of customers.
