TCL announce plans for H-QLED display technology
TCL’s ascent as a TV manufacturer continues apace. In 2015, the Chinese company became the world’s 3rd largest manufacturer of televisions and in 2018, they officially launched into the UK market. At CES this year they displayed both Micro LED displays and their Mini LED backlighting technology and now they have announced the development of a hybrid technology called H-QLED.
TCL doesn’t seem to be content with merely being purveyors of huge numbers of affordable, quality TVs based on well-established display technologies and instead seems to be pursuing an aggressive R&D agenda to put themselves on a competitive technological footing with the more established TV companies of Samsung, Sony, LG, Panasonic and Philips.

Now, the company has unveiled a new prototype display technology which is an amalgam of OLED and Quantum Dot technology - hence the reference to ‘hybrid’ in the nomenclature - H-QLED.

As reported by OLED-Info, TCL is taking a blue OLED emitter and partnering it with both a red and a green Quantum Dot emitter. Details are scant but it seems once these emitters are combined they will then be printed using an ink-jet platform. TCL is backing the resulting H-QLED technology as the backbone for future high-end TCL TV displays.

The use of ink-jet printing as part of the TV production process is something that TCL has invested in, resulting in a handful of prototypes. At CES back in January, the company demonstrated a 31-inch 4K H-QLED display that featured a brightness of 150 nits and supported wide colour gamuts of 80% of Rec .2020 and 112% of DCI-P3.

TCL is not the only player exploring this combination of Quantum Dot and OLED and Samsung are rumoured to be pursuing a similar goal. Both companies are faced with the same problem in the production process since commercial-grade red and green emitters are likely to be achievable with relative ease in the near future but the blue emitter could be problematic to develop which is why, for the time being, an OLED emitter is being used.

In theory, bringing together the best qualities of OLED and Quantum Dot technologies is highly desirable since it will see the high contrast and deep blacks of OLED and the wide colour reproduction of Quantum Dot together in one package. The result would be a TV featuring the best of both worlds in terms of contrast and colour which means the consumer no longer has to commit to a technology that is strong in one area but has drawbacks in others.
