I’ve been writing articles about quantum dot technologies since 2008. In 2013, I surveyed many quantum dot suppliers and published the first “Quantum Dot Display and Lighting Technologies and Market Forecast Report”. According to my industry friend, a CTO at a famous quantum dot company, “Jennifer, you are the first analyst who wrote a quantum dot market report, as far as I know.”
Quantum dot (including quantum rod, or tetrapod-shaped quantum dot) could improve Liquid Crystal Display (LCD) dramatically in terms of color gamut, color accuracy and reducing power consumption. This is one of the biggest breakthrough technologies for LCD in recent several years. Quantum dot LCD is challenging AMOLED displays.
- QD Vision and Sony brought quantum dot TVs to the market in 2013.
- Nanosys, 3M and Amazon brought quantum dot tablet PCs to the market in 2013.
- Samsung announced SUHD TV with quantum dot at CES 2015, and commercialized it since Q1 2015.
- LG Electronics also announced quantum dot TV at CES 2015, (but later LG changed strategy about quantum dot).
- Quantum dot was hot topic in CES 2015 to 2017, was hot topic at SID DisplayWeek from 2013 to 2017, and was hot topic at IFA 2014 to 2017.
According to the “Quantum Dot Display and Lighting Technologies and Market Forecast 2017 Report”, the quantum dot display has grown from zero dollar revenue in 2012 to a billion-dollar display category in 2017. The quantum dot display formed a new category—QLED (Quantum dot light emitting diode).
In the early years, “QLED”, or “QDEL”, or “QD-LED” were used in academic papers to call the electro-luminescent (EL) types of quantum dot. When an electric current is applied to these types of material, it will generate light. At this moment in 2017, the EL types of quantum dot is still in R&D stage.
Currently, 100% the quantum dot display that is commercially available is the photo-luminescent (PL) type quantum dot. When a short wavelength light (such as blue light) shine on a certain quantum dot, then it could emit a longer wavelength light (such as green or red).
In 2016, Samsung Electronics has applied for the trademark “Samsung QLED TV” with US Patent and Trademark Office. Samsung indicated that although they own the “Samsung QLED TV” trade mark, the “QLED” name is a common term like OLED TV or LED TV. “QLED” can be used by the whole display industry as a category name to call any displays with quantum dots in it.

Touch Display Research believes it is a good idea to use QLED as an umbrella name (or category name) to call any displays with quantum dots in it. Under the QLED umbrella name, the photo-luminescent (PL) type quantum dot can be called QLED PL type. The electro-luminescent (EL) types of quantum dot can be called QLED EL type.
QLED is a nice and short name. There is no need to reserve the QLED name for the EL type quantum dot only, since EL type is not in the market yet. When the EL type quantum dot enters the market (we forecast it will be after 2019), we can call it: QLED EL type.
