Samsung Galaxy Z Fold three could redefine foldable phones — here's how
If the Samsung Galaxy Z Fold three shifts to a new technology, then the mildly abrasive brandish crease that's present on fifty-fifty the all-time foldables will go less apparent.
That'due south according to OTI Lumionics, an advanced OLED materials and inquiry firm that has specialist knowledge when it comes to displays, folding or otherwise. The firm told Tom's Guide that foldable phones like the Milky way Z Fold iii are probable to see a less noticeable pucker in folding screens, along with other technological improvements, thanks to advancements in display materials and manufacturing.

Aslope the reduced crease, OTI Lumionics' market research, along with reports by Brandish Supply Chain Consultants (DSCC), have the Galaxy Z Fold 3 tipped to go a more responsive touch screen and an impressive under-display camera.
Every bit OTI Lumionics has developed a new filter technology that's currently inside the OLED supply chain, it's is confident in the Milky way Z Fold iii claims. Withal, the firm couldn't confirm if its engineering was being used in the upcoming Samsung foldable phones, but a representative did say that it "provides material for inquiry purposes to a number of OLED console makers and smartphone OEMs."
Simply if this applied science is adopted by Samsung and other smartphone makers, then we could see the Galaxy Z Fold 3 spearhead an evolution in foldabe phones.
Hither'south how Samsung Galaxy Z Fold 3 could reduce foldable display creases
According to OTI Lumionics and DSCC, the Milky way Z fold 3 will forgo the circular polarizer found on pretty much every smartphone and adopt a much thinner "color filter on encapsulation" (CoE) engineering.
That'due south all very technical and so let'south interruption it down. Most, if non all, phones ship with a circular polarizer inside the display stack (the layers that make up a screen). Information technology's a material that helps reduce reflections in brilliant light, improving visibility in sunlight.
The problem is that a circular polarizer can exist 81 microns thick, near that of a sheet of paper. That might non seem like a lot, only all these layers add together up and a thicker display stack tin can lead to a bulkier phone. The current Samsung Galaxy Z Fold 2 is hardly a slim telephone, then it's logical that Samsung might desire to observe slimmer materials wherever necessary.
And so both OTI Lumionics and DSCC believe that Samsung will become for a CoE material rather than a round polarizer for the neutralization of incoming light and reduce the thickness of the display stack.
"By jumping into this new engineering called colour filter on encapsulation, what they tin permit for is basically take more space now for other stuff to do," said Jacky Qiu, vice president of OTI Lumionics.
And Qiu noted that the apply of thinner materials would allow Samsung to then use thicker foldable drinking glass for the Galaxy Z Fold three'due south display. And as a consequence information technology would exist less prone to visible creasing.
Korean website The Elec has also reported that Samsung could use this new color filter material. And a recent written report by Ross Immature, co-founder and CEO of Brandish Supply Chain Consultants in Austin, effectively corroborated previous reports and Qiu's claims.
Yet, Young doesn't believe Samsung will use thicker glass to reduce display creases or that the display stack volition be thinner than before. Rather, Immature claims Samsung will incorporate a carbon reinforced polymer layer under the Milky way Z Fold 3 panel, with the same glass used by its predecessor.
"The Z Fold iii incorporates a carbon reinforced polymer layer to increment force below the console," Young told Tom's Guide. "The display film stack on the Z Fold iii is nearly 40% thicker than the Z Fold 2 despite the removal of the circular polarizer due to the addition of the relatively thick digitizer. It includes a shatterproof/protection layer under the UTG previously seen in the Z Flip 5G."
So even if thicker glass isn't used and the display stack remains thicker, the Galaxy Z Fold 3'south screen is still tipped to be more than crease-resistant thanks to the reinforcement. And if this tech filters down the supply concatenation to other telephone makers, we could encounter stronger and more than resilient foldable phone displays in the near hereafter.
Can the Galaxy Fold 3'due south rumored under-display camera compare to punch hole cameras?
Samsung'due south flagship phones take long been contenders in our best camera phones list, especially with the Galaxy S21 Ultra. Simply evolution of the selfie camera is the next telephone frontier, notably with the idea of putting it nether the brandish to avoid the use of distracting punch-pigsty cut-outs or notches.
The Galaxy Z Fold 3 is tipped to go such a camera, and Qiu told u.s.a. it could be the best one nonetheless. And that'll be down to the CoE technology.
With early-generation under-display cameras, there was simply nearly 20 to 22% transparency co-ordinate to Qiu, which doesn't allow for great front-facing photos. We've seen this happen in the ZTE Axon twenty 5G one of the first phones to send with an under-brandish camera.
But while display layers are expected to sit down betwixt the Galaxy Z Fold 3'southward rumored selfie camera and the pinnacle glass surface, Qiu reckons the use of a CoE cloth filter will let a lot more than light to motility through the display. And more light meant improve photos.
"And then if you get that 50 to 100% improvement, yous might become to 30% overall stack transparency," said Qiu. "It'southward still less than one-half as transparent every bit earlier, but information technology can, with more powerful backend algorithms, cameras, y'all can go everything up to par."
Immature notes that while not fully transparent like a hole punch the increased transmissivity could see the Galaxy Z Fold 3's nether-display camera deliver notable improvements over the ZTE Axon 20's camera.
Furthermore, Young says Samsung's computational photography could assist fe out some odd quirks with CoE, such as the "yellowing polyimide substrate" (the ZTE Axon 20 has a articulate glass substrate), which could make selfies await yellow before algorithms tweak the photo.
In the future, Samsung may be able to use a colorless polyimide instead, but current temperature requirements prevent information technology from existence used as a flexible substrate.
In that location'due south some other reward to using a proper nether-display camera in that information technology can brand a foldable phone more durable. According to Qiu, by pushing the photographic camera underneath the display, it should aid eliminate a potential weak betoken caused by light amplification by stimulated emission of radiation-cut a pigsty on the front end panel assembly.
"Instead of earthworks a pigsty, you lot tin can basically apply something that is existing, and you lot just basically stick on the photographic camera behind the display [information technology] can also improve the structural integrity," said Qiu.
Milky way Z Fold 3 improved impact and Southward Pen support
A modify in brandish tech has as well been tipped to make the Galaxy Fold 3's screen more than responsive to touch on and have S Pen compatibility; the latter we've already seen in the rumor factory.
According to a presentation past Immature at the SID 2021 Business Briefing, the Milky way Z Fold 3 could exercise this past using active electrostatic digitizer technology instead of electro-magnetic resonance for South Pen touch functionality.
Equally a result, touch response will be improved over the Galaxy Z Fold ii. And that will be handy equally foldables use softer glass than that found in standard smartphones, meaning there's more requite in the brandish that could make them less responsive when using a stylus. Only if the Galaxy Fold 3 tackles, this it could pb the way for other foldables to follow suit.
The future of foldable telephone prices and ubiquity
While the Samsung Galaxy Z Fold iii is looking like the foldable phone to watch, Young recently tweeted that Google, Oppo, Vivo and Xiaomi had purchased LTPO 120Hz UTG panels for foldables launching in Q4 of 2021.
Even with more companies getting involved with the space, foldables are notwithstanding out of attain for many buyers due to the high cost associated. The Milky way Z Fold 2 launched at $ii,000 for instance. And with the new tech Samsung's next foldable phone is tipped to have, it could be a while before the advancements filter downwardly to time to come affordable foldables.
Only every bit manufacturing gets better with increased foldable production, prices should follow. Sri Peruvemba, CEO at display firm Marketer International, predicts foldables like the Z Fold iii could autumn below the $1,000 mark in the next iii years.
Already, rumors are pointing to the Galaxy Z Flip iii creeping closer to that $1,000 price indicate. While a rumored $ane,249 isn't cheap, it'south better than the Galaxy Z Flip 5G's original $1,449 cost.
"What I'one thousand really excited near is if they tin can showtime bringing the Fold series outside of their domicile market in South Korea and be able to come across it around town here..." said Qiu. "Because this is definitely a tremendous device that is a head turner."
