There are two TV technologies available to most people right now:And . Sure, people with tons can get a , But only mortal people have two options. Samsung is the largest TV manufacturer in the world For many years, while Crosstown rivals . LCD, Despite Advancement , And , has always Overall picture quality.
Now Samsung is working on a new kind of TV, which aims to combine two display technologies into more than the sum of its parts. It is a hybrid between OLED andCalled QD Display. According to Korea IT News, Samsung Display will cease production of LCD panels by the end of 2021, moving to QD displays next year. At the same time, Samsung Electronics may start selling these new TVs in early 2022.
Here’s what we know so far.
Samsung’s $ 11 billion bet on quantum dots
Samsung has been selling LCD TVs augmented by Quantum Dots for the past few years under its QLED brand, but itsIt was closed over a decade ago. In October 2019, Samsung Display announced that it is building a factory to produce TVs that combine these technologies:
Samsung Display will invest 13.1 trillion won by 20.1 “Q1 line,” the world’s first QD display mass production line in Asa Campus. The new line is scheduled to begin production in 20,000 with an initial 30,000 sheets (8.5 generations) and will produce 65-inch or larger QD displays.
It is an investment of about $ 11.1 billion. While the company calls it “QD Display”, it is not. That technology is still many years away. It is going to be a QD-OLED hybrid.
At the time of the announcement, South Korea’s President Moon Jae-in also referred to Samsung’s rival LG regarding Korea’s location in world TV production: “It is important to maintain the top spot of the global display market with game-changing technologies , “Moon said. “Following LG Display’s 3 trillion-won investment in large OLED panel production in July, Samsung Display’s latest investment plan further brightens prospects.”
One thing you may have noticed is that Samsung is calling this “QD display”, which can be confusing as it is not direct-quantum dots (more on these later). Since LG has spent years being the only name (figuratively and literally) in the city for OLED, it is unlikely that Samsung will call any version of this technology OLED. We’ll probably have to wait until CES 2022 to find out how it brands the new TV.
How QD-OLED will work
So how will it work? Nanosys, a company that makes quantum dots, has shared some details. Its CEO, Jason Hartlowe, relies heavily on technology that relies on converting light from an OLED panel:
“Quantum dot color conversion is a new way of providing displayed color,” he told CNET. “The result is pure quantum dot color with much higher efficiency because the color filter loses no light.”
The combination of quantum dots and OLEDs play to the strengths of both technologies. To consider with any TV. LED LCDs with quantum dots, such as Samsung’s current QLED TVs, To change that blue to red and green. With the current version of OLED, . In both cases, color filters only pass what color is required for that specific subpixel.
The idea with QD-OLED is to simplify these designs into one, using OLED to create blue light, and then a quantum dot layer to convert some to blue and red.
This method has many advantages, in principle. By using only one color or material of OLED, the manufacturing cost is reduced because it is easier to manufacture. LG, for example, uses only two OLED materials, blue and yellow, for every pixel in the entire display. Light-blocking color filters make green and red. QDs have around 100% efficiency, which is much better than filters, so in theory hybrid TVs would be much brighter. In addition, there is also the possibility ofAt all brightness levels.
Because every pixel can be switched off, these hybrid TVs will also be unreliableOLED is known for.
Since blue OLED materials still age faster than red and green, having one color of the entire panel means that the TV ages more uniformly with no color shifts. Keeping aging to a minimum, and thus having a TV that does not seem to dim after a few years, is one of the major manufacturing issues. This is especially true inAge of extreme brightness levels.
While this new Samsung plant is focusing on TV-size displays, the technology can also work in phone-size displays. Since Samsung does not have any issues that are making excellent small OLEDs, I would be surprised if it is in any rush that might upset that market as if it is something advanced. Also, Samsung’s phone-sized OLEDs use red, green, and blue OLEDs compared to LG’s blue-yellow. Samsung tried to make RGB OLED TVs and simply could not make them profitable. What’s more likely, and mentioned in the latest rumors, is that they will use this technology to make ultra-high resolution 8K computer monitors with a TV screen.
As previously mentioned, it is clear that Samsung strongly believes in this technology, as it is ending production of LCDs in its factories in Korea. This does not mean that it will not start selling from next year. someone LCD. Samsung is a big company, and part of the company makes LCD, Samsung Display, Stopping Production. That part of the company Sells The TV, Samsung Electronics, has not made any such announcement. In fact, part of the most recent delay was Samsung Electronics needing LCD panels before they were ready to start selling QD-OLED panels. They have worked for 2021, and most likely will source their LCD panels from third parties.
QD-OLED seems right around the corner. But what about future display technology going forward? Well, quantum dot people think. These will not be about electroluminescent quantum dots or ELQDs, all the benefits of OLEDs, all the benefits of QDs and any issues of LCDs or OLED’s wear and longevity concerns. A very promising technique indeed.
Other new TV technologies that are already coming on the market are extreme high end of the market anyway. It has many of the same benefits as the QD-OLED hybrid, but doesn’t revolve around with those pesky organics. Affordable versions of that are still at some distance. Oh, and microLEDs also use quantum dots. They are an attractive technique to use .
