When buying a new Smart TV we have several options in terms of the panel and its technology. We have the traditional LCD or LED panels together with more advanced technologies such as OLED or QLED. QLED televisions include Quantum dot technology, a semiconductor that emits light based on the size of nanoparticles. Unlike OLEDs that are organic, they do not degrade over time. Samsung is already working on QD-LED, however, it seems that soon we will have news. In 2021 Manufacturing of the new QNED panels begins, but what advantages will they offer?
Korean firm Samsung plans to stop manufacturing LCD panels in late 2020 in favor of Quantum Dot LED (QD-LED) panels. Right now, this type of panel is positioned as the immediate future of the company, which is also contributed by the manufacturing problems of MicroLED. However, we could be closer than ever to starting to manufacture panels with a secret technology in which the television manufacturer has been working for a long time.
Advantages of QNED technology
As reported by ZDNet Korea, Samsung Display is going to start investing in the manufacture of QNED as of the second quarter of 2021. QNED is a new technology that stands for Quantum dot Nanorod LED. The main difference with QD-OLED is in the material of the pixels and in the manufacturing process of these. A couple of months ago we started talking about this technology and we may soon have the first televisions with these advantages. Some 30,000 panels are expected to be manufactured in that second quarter of 2021.
In QD-OLED panels, Samsung uses the same principle as in its QLED televisions, where the backlight is done with blue LEDs. Here the red and green quantum dots filter out the colors they need to display correctly, while the blue color passes through without filters directly. However, in the QNED the particles are used GaN Nanorod for blue light emission.
These are more energy efficient, we have a improved brightness, longer panel life or complete absence of burning problems. Samsung will continue to use Quantum Dots or quantum dots in the color conversion process for red and green pixels.
Finally, another of its advantages will be the manufacturing cost. QNED panels are expected to be cheaper to manufacture than OLED, microLED and QD-LED, although the manufacturing time is longer, something the company is currently working on. Like any emerging technology, it will take us a few years to see it as a market trend.
