I got this phone in a couple weeks ago and I immediately noticed that the screen and the hinge were just unlike anything I've seen before. I reached out to OPPO and I asked them if they could sponsor a video so I could show you guys this tech a little bit earlier than usual. So, this is the Oppo Find N6. Uh, and okay, to appreciate what's going on here, I got to show you some of the other folds I have here. This is the last one that I purchased, the Samsung Fold 5. This is a couple years old at this point, but this was a great device. The crease was very noticeable. You can see it very clearly here. And when you run your finger across it, it's like super obvious that you're going over
like a speed bump in the middle of the screen. Uh this is the latest Pixel product or foldable Pixel product. This is the Pixel 10 Pro Fold. This same deal, right? Very visible crease. Now, this over here is the Samsung Fold 7. This is actually broken unfortunately, [snorts] but same idea. You can see the uh it's a very visible crease and again when you run your finger across it, it's very obvious when you're when you go over it. Okay, it's a problem that the entire foldable market has had since the inception of foldable phones. But this is quite different. So, the Find N6 has what they call the zero feel crease that hides the crease visibly, but is an almost imperceptible crease when you run your finger across
it. It's faintly visible. So, I'll turn it off. It's kind of most obvious when you have the screen off. You tilt it at just the right angle, you can kind of see it. Yeah, it's there, but you can't feel it at all. It actually feels like a smooth, continuous piece of glass. So, how did they do it? How did they do something that Samsung couldn't do? So, part of it is the hinge. This is their second generation titanium flexion hinge. So, if you look at this thing really close up, you can see that there's this like blue tinted material on the central plate. And this is the secret sauce. This is their 3D liquid printing. So, usually hinges have these tiny microscopic variations in height right along the spine of the phone. And
it's like 0.2 0.3 mm difference in height. It seems insignificant, right? Like what are we talking about 2 millimeters? But when you take a really thin flexible OLED and you put it on top of something like that, those height variations translate into a pretty noticeable crease on the screens. So to solve this, OPPO laser scans each individual hinge with.3 micron precision. And then they apply these little droplets of photopolymer, like tiny amounts. I think it's like five pico liters, like incredibly small amounts. And then they cure it with a UV light. And they do it over and over 20 times until they build it up layer by layer until it's smooth. So it goes from like the height variation of 2 mm down to 0.05 mm. It's a massive reduction in
like bumpiness. And the result is something that's 75% smoother than a typical hinge. And now when you put a flexible OLED on top of something like that, it's almost perfectly smooth. And if you compare this to like the Fold 7, like right, it's just that valley is super obvious on this one in comparison to the Find N6. But there's a second issue that foldable phones have. It's that the crease gets worse over time. Like when you get them new, the creases look great, but as it ages, 6 8 months in, the creases get deeper and more visibly obvious. And even sometimes they can you can feel them in a more obvious manner. And it's simply because the
adhesive between the different layers of the OLED start to shift over time. And that's the importance of removing creases. Like the visual imperfections are one thing, but if you can feel a crease, it means there's a physical stress point. And every time you fold it up, you create these shearing forces that cause the older layers to shift. And that's how most foldable screens break. So OPPO addresses this in two ways. First, they do a water drop design with the fold mechanism. So as you fold the device up, instead of like a sharp acute bend on the screen, they make something that's a little more gentle. So it's like a kind of wider kind of curved bend and it just puts much less
mechanical pressure on the panel itself as the device folds up and it's an 11% wider water drop this generation. Now the second thing that OPPO does is their new glass. They have this new material called auto smoothing flex glass. And it's a glass that is thicker and more elastic than the typical ultra thin glass on foldables. And because it's thicker and more elastic, every time you open it up, this top surface acts as like a it almost like springs back open and pulls those OLED layers back open and realign all the adhesives that have shifted around from being folded up. It seems like it'd be very effective at maintaining the durability and just longevity of the screen. They're claiming up to an 82% reduction in
crease depth over time compared to the previous generation. And this hinge is extremely durable. It's got a titanium hinge casing and titanium wings. It's got carbon fiber support plates. And the phone is triple certified. It has IP 56, 58, and 59 ratings. And I was super confused by this. I was like, why all three? Like, isn't it cumulative? And it's not. By having all three, you have it that it can be submerged. It can also withstand high pressure and can also withstand high temperature water jets. It's like it's a very at least seemingly durable hinge and phone. But the spec that was most impressive to me is the fold rating. So this device is rated for 1 million fold cycles. Like
you open and close, that's one cycle. A million of them. The Fold 7 is rated for like 500,000. And the older phones are all significantly lower than that. A million. And they're claiming that at 600,000 this screen should still open up to be exceptionally flat. So, the OPPO Find N6. This is super cool screen tech. Super cool hinge tech. I'm glad I was able to share it with you. I never thought that the solution to like creases on screens would be 3D printing stuff on the hinge to be able to like flatten it out like that. It's so neat. All right. Hope you guys enjoyed this video.
