Like razors and hamburgers, the key to better OLED seems to be more stacks. The OLED layer stacked on other OLED layers will lead to a brighter and brighter display. OLED screens on TVs, monitors, laptops and phones already offer the best image quality for any display technology, and using two new technologies, they promise to get better.
LG’s latest high-end OLED TV G5 has a four-pack design, resulting in the brightest OLED Pictures CNET that has tested to date – over 30% higher than any other OLED TV we’ve tested. For some of the existing performances, this is a great development The best TV once.
New advances in phosphorescent materials that supplement OLEDs usually luminescent materials may be equally interesting. This new technology may increase brightness more or provide a more efficient display for portable devices. Are these advancements just hype? Probably not. This seems to be a serious increase in OLED performance. This is why.
Stack Stack
LG’s third-generation OLED, like previous generations, used blue OLED material with yellow or yellow OLEDs, plus color filters to create red, green and blue light. The new design uses separate red and green OLED materials, which are rare materials for TV OLED designs.
To understand why this new design is worth noting, let’s first take a moment to talk about previous generations of OLEDs and how they work. Before popular comments, modern OLED TVs did not create light without red, green and blue OLED materials. Samsung experimented with RGB OLED early on, but couldn’t make it cost-effective. Instead, LG has long made some version of blue OLED as well as yellow or yellow-green OLED materials. This “white” light will be made through a color filter to create the red, green and blue colors that make up the image. They will add an extra white subpixel to increase brightness.
We’ve talked about this before, and while it seemed odd at first, it looked great at the time and it only improved over the years. Samsung finally took a different approach when it re-entered the OLED market with its QD-Ol design. This is used The only one Blue OLED material, and red and green added Quantum dots Create a rainbow of fruit aroma.
The problem from a technical perspective is that you can only put OLEDs so hard. There are many reasons for this, especially life span. Essentially, the candle burns twice as much. What engineers discovered was that if OLED layers were stacked on top of each other, they could work together to create a brighter image without being particularly hard on any individual layer. As in “33+33+33 = ~100”, its advantage is more than “100 = 100”. There are more to it than that, but that’s how we got here.
Not only are there more stacks, but also different stacks
So with that in mind, I’m sure you’ll see that adding another layer is logical (“33+33+33+33=profit!”). Although basically true, there is another change here, because from the early days when people who wrote about OLED, I found that LG has become RGB.
LG calls its new fourth-generation technology “main RGB tandem”. It has two blue OLED heaps and then swaps the yellow-green layer for separate green and red layers. (RGB OLED returns!) The biggest advantage here is better color performance at higher brightness levels. Creating green and red without using yellow-green materials has obvious efficiency advantages. Blue, a long-standing OLED child problem, has still doubled the problems in the new design for brightness and longevity reasons.
In CNET’s test of G5 OLED, we measured about 2,800 columns, which is 40% brighter than other OLED TVs we’ve reviewed, the Samsung S95D, than the previous LG G4. Even if our tests don’t match LG Display’s 4,000 column claims, this is still a significant increase after years of relatively modest improvements.
Phosphorescence

LG also recently announced another OLED breakthrough, which isn’t ready for TV’s “golden time” but is just as fun, at least if you’re a nerd like me. To date, the blue OLED material used in TVs is luminous. This basically means that when you give them energy, they glow and when you turn it off, they dim. Phosphoresis works slightly differently. Supply energy to the phosphorescent material and emit light. How long does their glow vary, but interestingly, phosphorescent materials tend to be much higher than luminescent materials. They “hold” energy for a moment, releasing more light than the “instant” conversion of luminescent materials.
Phosphorescence Blue OLED is a bit beluga in OLED designs, and LG and Universal Display Corp finally broke down (it has been studied for a long time). They combine the fluorescent blue layer with the phosphorescent blue layer, currently pairing it with the yellow-green layer. This combines “the stability of the fluorescent material with the power efficiency of the phosphorescent material, thus reducing power consumption by about 15%,” LG said.
Currently, LG intends to use this technology in displays that require high brightness and efficiency, namely smartphone and tablet screens. Can the four-pack designs in LG’s new TV be modified to use a phosphor layer for brightness and energy efficiency? I think at least it ends up being that way.
The new king is now?
The next generation of television technology has many names: QD-EL, EL-QD, nano, QED; also known as direct view, electrologic quantum dot.
It’s logical to drift towards Samsung to understand what its reaction is. However, I’m not sure if they need one. At least not now. Its QD-old technology is very novel and very good. Quantum dots are excellent, and the efficiency of turning one color into another is almost 100%. QD-oled does not have the same potential limitations as color saturation in older LG designs at high brightness levels. So if Samsung adds more stacks (somewhere between possible and possible), it is theoretically possible to get greater brightness while maintaining color saturation. If the company switches to phosphorescent blue material, it can see improvements in brightness and efficiency, as LG claims. We will see it.
We can also imagine that, on the horizon, it might replace OLED. QD-el, also known as nanometers, also known as direct view quantum dotscreate images using electroluminescent quantum dots without OLED or LED. After years of restricted tech demonstrations, TCL’s prototype just sat on the booth at CES 2025, and can be seen by everyone (at least, everyone who notices). During the Information Display Association’s presentation week, Samsung presented a 400-NIT QD-EL prototype. As far as this technology is concerned, it’s big and bright. (We love the big and bright ones.) It will be a fun few years for the display technology, which is for sure.
