News hardware OLED TV: Samsung is already developing a big improvement to its QD-OLED technology
After only a few months in the OLED market, Samsung already has a strong position, and doesn’t seem to want to stop there. The brand announces at a show the next version of its QD-OLED screens, which would pass yet another milestone, and perhaps for less.
Samsung’s QD-OLED is already getting better
For a long time, Samsung was content with its QLED technology, without venturing on the path of OLED like its competitors. This is now ancient history and with its new QD-OLED technology, the South Korean firm surprises with its S95B models.
The main problem with standard OLED, called W-OLED, is that without a backlight, the total brightness of the self-emissive pixels is lower than what LCD offers. W-OLEDs use a fourth pixel which is white and is not intended to display colors, but simply to create more brightness. But the result is not perfect.
The solution, Samsung found it with QD-OLED: use the Quantum Dot that we know on QLEDs and apply it to OLED to obtain panels that are both very contrasting and have infinite blacks, but also with a brightness that undermines the W -OLED. We can also say goodbye to blooming, an unpleasant effect that spreads the light around the subject, creating a luminous halo all around.
Currently, QD-OLED panels are simply the brightest available on the OLED market. We can reach 1500 nits, when most competitors are limited to around 1000 nits. QD-OLED technology also provides access to a wider color palette than conventional OLED panels.
Samsung’s new innovation, brighter and less expensive
It is the Korean site TheElec which reports this information, and it is good news for OLED enthusiasts on smaller budgets.
QD-OLED is a success story, and at the SID 2022 OLED event in Seoul, Samsung showed off what they plan for the future of the technology. The organic emitters from the QLED and used in the QD-OLED are blue and are used to create this color but also to react red and green nanocrystals, to obtain all the colors of the rainbow.
The blue emitter is a fluorescent type, and to prevent it burning and to be efficient enough, it needs three layers. This greatly increases production costs.
Samsung is going to switch to phosphorescent and non-fluorescent blue emitters, which can transcribe the light much better and are much more resistant. So it only needs one coat to work, and can portend even higher luminosity.
This is therefore an advantage also for the luminous efficiency but also for the consumer. The goal of this innovation is to make QD-OLED technology accessible to as many people as possible. For the moment, it remains necessarily a little expensive because of its recent arrival.
According to TheElec, this new version of the QD-OLED should arrive on the shelves around 2024.
