内容总结：

苹果首款折叠屏手机iPhone Duo发布后引发广泛关注，其屏幕折痕问题成为焦点。该机型采用纳米纹理屏幕涂层，可显著减少光线反射，有体验者称折痕“几乎看不出来”，但也有人指出折痕依然可见且会随时间加重。实测报告显示，折痕“用手指触摸比用眼睛观察更容易察觉”。然而，折痕问题难以一蹴而就解决，折叠屏手机普遍存在累积损伤，三星Galaxy Z Fold 8便是例证——新机展开时屏幕平整，但反复折叠后折痕愈发明显。多位苹果高管公开表示对iPhone Duo的耐用性充满信心，但纳米纹理屏幕的实际表现仍需在大规模用户使用后才能验证，其长期耐用性更有待时间检验。尽管在发布会体验环节中折痕几乎不可见，但任何上手体验都只是手机尚未经历长期折叠的“快照”，真正的考验在于使用数月之后。不过，苹果能让折痕在初期显得如此不明显，已属积极信号，预计竞争对手也将很快跟进。

为什么我们很久都无法知道iPhone Duo的折痕到底有多明显

苹果的纳米纹理屏幕可能无法永远掩盖折痕。

苹果首款折叠屏手机即将问世，本月初发布时便引发了不小的轰动。这并不令人意外，毕竟大家都在期待iPhone Duo会如何解决竞品的短板。不过现在下定论还为时过早——这款手机要到下个月才正式开售，目前我们所能接触到的也不过是几次简短的上手体验。

但最受期待的特性之一，是全新的纳米纹理显示屏，苹果承诺它能让屏幕上的折痕变得几乎不可见。事实上，折痕确实看起来不那么明显了——但要想确凿地验证这一点，还需要很长时间。

折叠屏手机最大的代价：折痕

从以往来看，折叠屏手机一直存在一个令人不悦的缺陷：折痕。归根结底，这是物理规律决定的。以目前的技术水平，几乎不可能让一块可弯曲显示屏在折叠后完全不留下任何折痕。各家厂商在这方面已经有了长足进步，折痕虽然依旧存在，但已经不那么显眼了。

苹果采取了一种巧妙的方法来让折痕更不易被察觉。iPhone Duo的屏幕表面覆盖了一层哑光涂层，能显著减少光线反射。一些亲眼见过iPhone Duo的人表示，折痕几乎看不出来。也有人认为折痕仍然可见，而且变严重只是时间问题。

我们自己的上手报告发现，折痕“用手指摸比用眼睛看更容易感觉到”。但这是否意味着苹果凭借iPhone Duo彻底解决了折痕问题？并非如此。

这里最大的问题在于累积损伤。以Galaxy Z Fold 8为例。三星出货时折叠屏手机在包装盒中是展开状态，你第一次看到它时，屏幕看起来非常平整。但当你开始反复折叠和展开之后，折痕就会明显变得更加突出。再想象一下，在数月乃至数年的时间里将这块屏幕折叠数千次。网上不难找到折叠屏手机屏幕受损的照片。

只有时间才能证明苹果是否做对了

多位苹果高管公开表示，他们对iPhone Duo深感自豪，并相信这款设备会比竞品耐用得多。但在iPhone Duo到达大量消费者手中之前，我们无法确定其纳米纹理屏幕的实际表现。不仅如此，要了解它的耐用性如何，很可能还需要一段时间。这必然会成为许多YouTuber在极端耐久性测试中重点检验的项目。

所以没错，在苹果发布会上的上手体验环节中，iPhone Duo屏幕上的折痕确实几乎看不出来。但即便最详尽的上手感受，也不过是一条尚未有时间发展的折痕的瞬间快照。即将陆续出炉的评测——包括我们的在内——也只能说明iPhone Duo刚开箱时的状态。使用几个月之后，情况可能就不一样了。

不过，这一点还是要给苹果点赞。该公司打造出了一块在最初几天里就能让折痕看起来不那么明显的屏幕，这无疑令人期待。这也是我们应该会看到竞争对手很快争相追赶的方向。

Why we won't know how visible the iPhone Duo's crease is for a long time
Apple's nano-texture screen might not hide the crease forever.
Apple's first foldable phone is coming soon, and it caused quite a stir upon its announcement earlier this month. That's no surprise, since everyone was waiting to see how the iPhone Duo would address the competition's shortcomings. It's still early to tell, given that it won't hit stores until next month and all we've had so far are a few brief hands-on experiences.
But one of the most anticipated features is the new nano-texture display, which promises to make the crease on the screen much less visible. In fact, it does seem to be much less noticeable — but it will be a long time before we know for sure.
The biggest trade-off with foldable phones: The crease
Historically, foldable phones have had an unpleasant flaw: the crease. And it all comes down to physics. With today's technology, it's nearly impossible to have a flexible display that folds without leaving any crease marks. Companies have gotten much better at this, and the creases have become less noticeable even though they're still there.
Apple took a clever approach to make the crease less visible. The iPhone Duo's screen has a matte coating on top, which significantly reduces light reflection. Some people who have seen the iPhone Duo in person say the crease is barely noticeable. Others say it's still visible and that it's only a matter of time before it gets worse.
Our own hands-on report found the crease is "easier to feel with your finger than observe with your eyes." But does that mean Apple has finally solved the crease problem once and for all with the iPhone Duo? Not really.
The biggest problem here is cumulative damage. Take the Galaxy Z Fold 8 as an example. Samsung ships its foldable phones unfolded in the box, and when you look at them for the first time, the screen looks super flat. But as you start folding and unfolding it, the crease definitely becomes more noticeable. Now imagine folding that screen thousands of times over the course of months or years. It's not hard to find photos of foldable phones with damaged screens online.
Only time will tell if Apple got it right
Multiple Apple executives have publicly stated how proud they are of the iPhone Duo and how they believe the device will be much more durable than the competition. But we won't know for sure how the iPhone Duo's nano-textured screen will perform until the phone reaches a mass of consumers. Not only that, but it will likely take some time before we have any idea of how future-proof it is. That will certainly be something many YouTubers will put to the test in their extreme durability experiments.
So yes, the crease on the iPhone Duo's screen was barely visible during the hands-on sessions at the Apple event. But even the most thorough hands-on impression is really just a snapshot of a crease that hasn't had time to develop yet. The reviews that will roll in soon, ours included, can only speak to what the iPhone Duo looks like fresh out of the box. That might be different after using the device for a few months.
Still, you have to give Apple credit here. The fact that the company created a screen that already makes the crease look much less noticeable in the first few days is certainly promising. It's also something we should expect to see the competition rushing to catch up on soon.
