Hi, this is Wayne again with a topic “Why Foldable Phones Are a BAD Idea”.
Between VR headsets and electric cars, there are plenty of things all around us that scream we’re living in the future. But if you want something you can carry in your pocket to remind you, look no further than the foldable phone, except for one small problem. Where did they all go? The first model that looked like it was going to make it to market the Samsung Galaxy fold. Has been riddled with problems that have caused its release to be delayed, it turns out that making a foldable phone worth its salt is a lot more work than just chucking a hinge and a flexible screen at your existing product. So let’s talk about why foldable phones might not be ready for primetime just yet. The first thing to consider is just how thin a foldable display needs to be in order to be usable, no one’s going to want to buy an ultra thick device straight out of the 1980s or feel like they’re, trying to fold a piece of cardboard in half Every time they close their phone, that means that both the screen itself and the underlying structures that support touch functionality need to be less than a millimeter thick and packing. All of that Hardware into such a small space means that all the components inside need to be made very thin, which also means they’re incredibly fragile.
Unsurprisingly, this presents problems with yields, which are how many displays come off. The assembly line fully functional compared to defective now. According to this post from IHS market, the OLED displays that are used in smartphones have a yield of around two-thirds. By contrast, foldable touchscreens have a yield of under 30 %, so not only are foldable phones already expensive due to the newness of the technology and the complexities of the manufacturing process.
They also have higher resource costs due to the wasted materials and fab time from low yields. Now, let’s get into the materials themselves, like the plastic, that’s used for the top layer of the display in a traditional non flexible smartphone, the top layer is made of toughened glass and in recent years, that technology has advanced to the point where many phones are not Only reasonably resistant to scratches, but even high-impact drops you can learn much more about that up here. Problem is flexible, glass, isn’t really a thing at least not yet, and that means that foldable phones have to be made from less durable plastics, making an already fragile device. Even more prone to failure, or at least scuffs, and scratches all right so so far, we’ve got cutting edge, low yield, manufacturing, thinner, less durable screens and less durable coverings for them. What more could go wrong? All right? The fact that the user is going to be constantly opening and closing these things, whooping them open, snapping them shut and I’ve even seen the fold described as a remarkable fidget clicker. So, in a way, folding phones take the industry trend of having as few moving parts as possible and completely turn it on its head by making the most fundamental component something you’ll use.
Every time you touch the device, essentially a moving part and making matters worse. Foldable phones also present other less obvious avenues for failure. For example, the Galaxy fold notably had a couple of gaps in between the screen and the frame that allowed the hinge and the display to move properly too bad. They also allowed debris to enter, which is exactly what happened to a couple reviewers, who noticed bulges in the screen.
After a short while and considering that phones are portable, devices meant to be carried in a pocket, preventing things like dust and Pocket lint from getting inside them will have to be a major design consideration for any manufacturer that wants to take a stab at making a Foldable one with all of that said, we’re not actually hating on the idea of being able to carry around what is essentially a tablet in your pocket that you can whip out to watch movies in your self-driving car or whatever. We want them to succeed and we think that, given some for the technology to mature, they will so when we said they were a bad idea. We were referring to the idea itself, but rather to the idea of rushing to market in a wild attempt to gloriously proclaim yourself to be the first like, okay, yeah sure being first is cool, but the problem is, if you don’t also add something of substance, you Just end up looking kind of foolish, it’s making a foolish don’t be foolish use.
