Quantum Dot LED Display Development Kicked Off by Quantum Materials Corp

Quantum Materials are now supplying tetrapod quantum dots to an Asian manufacturer of LCD displays. Tetrapod quantum dots are a high-efficiency display technology that could revolutionize the market.

Quantum dots are nanoscale structures, which are so small their structure directly affects their optical and electrical properties.

For example, quantum dots made of the same material emit different colored light depending only on their size.

This unusual property, coupled with their high brightness, makes them very attractive to manufacturers of displays. In most types of display, red, green and blue emitters require different chemicals. This is true of LCDs, LED and OLEDs. With quantum dots however, a single material can be used to create a full color display, keeping manufacturing costs low.

Quantum Materials have another advantage which will help make quantum dot displays commercially viable. Their green, efficient continuous flow process makes transitioning to high-volume manufacturing an easy step. Quantum dots can also be made without toxic materials or rare earth elements, keeping the cost of raw materials and processing down.

"Tetrapod Quantum Dots ultimately allow for lower display manufacturing costs due to their superior luminescence and much lower incidence of aggregation. Far fewer quantum dots are required to achieve the same level of performance.  We believe this performance advantage coupled with our continuous-flow manufacturing technology will insure the lowest quantum dot cost."

Stephen Squires, CEO, Quantum Materials

The news that a major electronics manufacturer is working with Quantum Materials on quantum dot displays is very exciting for the display industry - Wintergreen Research published a report on the quantum dot display market in 2013, which predicted that as soon as one manufacturer successfully adopts the technology, all the others will have to quickly follow suit, or be left behind.

It isn't difficult to see why this might be the case when you look at the benefits of quantum dot displays. "QD-LED" displays can be lighter, brighter, more energy efficient, and will offer incredible levels of contrast and precise color reproduction.

The technology is still at an early-stage commercially speaking, but the electronics industry moves fast, and it will be fascinating to see the first prototypes of these game-changing QD-LED displays when they emerge.

  1. William Leigh William Leigh United States says:

    I think you should consider investing in the company - OTC Ticker = QTMM

  2. Ted Johnston Ted Johnston United States says:

    Will, when you state "Quantum Materials are now supplying tetrapod quantum dots to an Asian manufacturer of LCD displays" are you referring to QMC supplying samples to a manufacturer for evaluation per the PR or do you have information that QMC is supplying Qdots in bulk for manufacturing?  Thanks for the clarification.  Ted J

    • Will Soutter Will Soutter AZoNetwork Team Member says:

      Hi Ted - this is in reference to the press release, the QDs have so far been supplied in sample quantities only.

      • Ted Johnston Ted Johnston United States says:

        Will, you may want to look at an article on Nanalyze:

        "The press release referenced by Aoznano states that Quantum Materials Corp  has “shipped Tetrapod Quantum Dots in sample quantities to a diversified leading Asian-based electronics manufacturer”. Assuming that these were solicited shipments, it still hardly means they are “supplying” to this leading manufacturer."


        They are pointing out the fine line between supplying samples and supplying materials for production and inferring a lack of attention to detail.  The rest of their article was based on some pretty thin/out-of-date reseach and does not provide clear picture of QMC.  They seem to more focused on just making others look bad.

        You might want to consider looking more closely at QMC and seeing if you can provide a more balanced article.
