What is Quantum Dot Display


A quantum dot display utilizes quantum dots(QD), or semiconductor nanocrystals. The quantum dots may discharge light, or simply change over it, in LED-illuminated LCDs. At present, every single business item, for example, TVs utilizing quantum dots, and marked as QLED, utilize them to change over light for LCD backlights, rather than as part of the actual display.

Quantum spots are incredibly little particles. They extend between 2 to 10 nanometers in diameter, which is equivalent to 50 atoms. You can’t measure these things. It’s this small size that gives quantum dots the unique properties to improve techs.

This display technology would be like organic light-emitting diode (OLED) displays, in that light would be radiated on demand, which would enable more effective displays, and is also seen as the next generation technology after OLED. However, such products are still experimental. The European Commission does not exempt the use of cadmium for lighting to create these QLEDs.

It could support large, flexible displays and would not degrade as readily as OLEDs, theoretically making them good candidates for flat-panel TV screens, digital cameras, mobile phones and personal gaming equipment.

Benefits of Quantum Dots

Higher peak brightness

Quantum dots is that they allow them to produce TVs with much higher peak brightness. This opens up some interesting possibilities, such as enabling support for ‘high dynamic range’ TVs that support standards such as Dolby Vision.

Better color accuracy

Another big benefit of quantum dots is improved color accuracy. The light produced by quantum dots is so closely tied to their size that they can be tuned very precisely to emit the exact kind of light needed. This means purer, cleaner whites and more precise colors.

Downsides of Quantum Dots

A potential drawback when used in biological applications is the fact that due to their large physical size, they cannot diffuse across cellular membranes. The delivery process may actually be dangerous for the cell and even result in destroying it. In other cases a QD may be toxic for the cell and inappropriate for any biological application.

Their quite extended lifetime may be a hindrance to certain applications that require QDs to biodegrade immediately after the experiment has been performed. In certain cases however it is possible to remove the QDs by simply washing the cells with appropriate solutions.
