As a digital enthusiast My dream phone would be Think big and think small Apparently the folding screen will do the trick The world's top 7 mobile phone manufacturers Six of them have already introduced folding screens But the number one of them is Apple Nothing has been done yet And from Apple currently According to the information on the exposed plan map A foldable iPhone is a long way off Maybe in three years, maybe in five Maybe not at all I wonder if we could build one ourselves Hi, I'm NaYan Welcome to the aesthetics of technology @KJMX Don't worry. Turn it off. Isn't this video about how to make a promo It's about making the promo real Edwin, how much does it cost to make a foldable phone The folding screen is about $10,000 It shouldn't cost us much to do it ourselves All right, well, let's get to work and you can do it Wanted to make an iPhone with a folding screen The first thing to solve is the folding screen For color accuracy and better display effect We're not using low-cost third-party screens Instead, they chose the Apple iPhone The original screen to get a makeover Take the iPhoneX screen, which has the most features Take a look at it first by dismantling it The composition of the iPhone's original screen A full iPhone screen The TP layer is made of an outer glass cover Polarizing layer OLED panel Screen retainer and 3D Touch The structure consists of six layers To make a bendable foldable screen You need to do it without destroying the screen Remove the glass cover and 3D Touch layer It's not hard to detach the iPhone's original screen But the separation still has to show the perfect effect You also need every layer of structure to work properly That would be very difficult The structure of each layer of the screen They all require a different approach One of the simplest is the outer glass cover Let's say the screen on your phone accidentally cracked But if you can still operate your phone The lower touch layer and display layer are not damaged Then you can do it for a very low price Replace only the top glass structure of the screen This is also known as the back press screen Touch won't work if the screen cracks So at the same time as replacing the cover plate You also need to replace the TP layer But when you have a leak on your screen Or when the red and green lines run through That would require you to replace the entire screen Or replace the single piece And if the 3D Touch layer is damaged You need to replace it from the back You already know what each layer of the screen does Then it's time to start the transformation The goal is to preserve the original display And touch functions at the same time Reduce the hardness of the screen as much as possible In order to achieve the effect of bending Edwin, is it too expensive for us to use the original screen The original screen works well It's only about 1,000 yuan a tablet We'd like to introduce the engineers from our science and technology aesthetics team This is also the iPhone folding The director of the project, Edwin It's up to him to introduce it to you How do we make a slice The original iPhone screen that bends The iPhone's original screen was delicate and fragile To achieve a perfect separation The first step to remove the bracket is very error-prone So Apple is on the iPhoneX screen COP packaging process was adopted for the first time The entire bottom of the screen is bent 180 degrees The advantage is that the iPhone has the highest number of mobile phones in the same period The smallest chin is very beautiful But when it comes to disassembling the screen, it's a nightmare We can see the outermost bracket Directly wrapped around the substrate connecting the FPC and the drive IC The glue is just in the position of the line You have to do it with the right force It could be damaged if it's not right After the stent is removed The cover layer needs to be separated and the TP layer retained That's the touch layer We use gold wire to enter the corner section Transverse cutting Because the TP layer is particularly thin So we need to control the temperature when we operate And grasp the strength of the gold wire If there are impurities dust down the diamond wire into the interlayer This will cause the TP layer of the screen to crumble This breaks the touch function After removing the cover plate, we need to remove the glue The process seems simple enough It's also a very high risk Especially at the bottom of the line It is particularly vulnerable to damage The whole process takes a long time on the screen Keep it at a high temperature You can burn your skin like this if you're not careful After more than a month of separation and separation Our separation and degluing techniques are becoming more and more skilled But at the end of the day, it's also the operation And the screen itself I didn't get a piece A screen that fully meets our modification requirements More than five months had passed And the budget is pretty much spent Edwin, how much money did we spend here emm…
More than twenty thousand That's a lot of screens to buy I don't think we'll need more than a few more Because we want a full screen No leaks, no bright spots, no bad spots And you can bend it So in the first few months We are constantly looking for good health Bendable original screen Because the iPhone's original screen is a multi-layer structure Each layer separated has a high chance of damage Even if the two layers are successfully extracted But bending will also face a high probability of line damage There is also the issue of bending and shifting the screen causing the black screen But we didn't give up For the next two months We continue to buy a lot of iPhone screens Try different ways to reinvent Gradually mastered the characteristics of different batches of screens Each time we fail, we gain experience Test and error to find the most suitable batch model All the hard work pays off in the end When we're done with the 37th original screen And connect the cable to the iPhone motherboard A moment of light We've waited a long time for this Don't count your chickens before they hatch A single flexible screen It doesn't make a full fold-out phone Edwin's axle remodel shouldn't cost much The shaft is not as brittle as the screen It doesn't break and it doesn't cost much The axis of rotation of the folding screen In fact, it is the most critical part of the whole machine bending Is it enough to support a two-stage fuselage Whether you can give the screen enough protection is critical For this we must seek The solutions of the major tech giants The first thing that comes to mind, of course, is Samsung Samsung released it in February 2020 The Galaxy Z Flip The well-known institution of technological aesthetics Also carried out the first unpacking experience At the time its compact fuselage was closed with a rotating shaft I was deeply impressed Here we bought two Galaxy Z Flip to disassemble To save space inside the fuselage Samsung uses small stacked motherboards The inside edge of the fuselage is equipped with strong magnets Achieve solid rebound when folding The rotating shaft section has a complex and strong spring hinge It has strong resilience when expanding and folding the screen I can say that the design is very clever But it's a shame about Samsung's pivot plan It doesn't fit the needs of the iPhone's foldable screen First, the Galaxy Z Flip The space is very small after folding Samsung, though, has custom-made high-strength flexible screens But you can see after two years of use Its screen still suffers from visible fatigue damage And the iPhone's display It was obviously not developed for folding It's vulnerable to separation It's also not strong enough to withstand such a large Angle of bending So we have no choice but to abandon Samsung's proposal In September 2020 Tech aesthetics is out of the box for you The MOTOROLA razr moto's phone impressed me the most It has a very small crease It's a big difference compared to Samsung So we bought two more moto Razrs to disassemble The moto's internal wiring is complicated There are separate rows on the back cover and front screen It's like two systems The fuselage structure is also clear It took a lot of glue to hold it in place But it's not difficult to disassemble To give the battery more room moto uses a single-layer PCB Add plenty of shielding As for the folding axis structure that we are most concerned about It runs through the center of the phone The opposite gears connect the springs of the two support plates When the phone is turned on The lower spring plate pulls the screen tight Keep the phone screen close to the center frame for force protection Between the two support plates when the phone is turned off It's going to be 7mm of vertical space To accommodate the bent screen You'll find moto's solution unique The razr's screen and shaft parts are separate When folded, the screen takes on the shape of a curved water drop Yes, this axis of rotation is what we need It can give a flimsy iPhone screen More longitudinal space protection More than half a year was barely settled Screen and pivot issues Then there's the more cumbersome motherboard Our budget is long gone by now The folding screen is about $10,000 The original screen looks good It shouldn't cost us much to do it ourselves I don't need more than a few and I just need a few more It's only about 1,000 yuan You tell me the truth How much more does this motherboard need You don't have to go because I'm about to cut a watermelon You see this watermelon is not bad These were good last time Oh, don't spend it.
Don't spend it We can just rip the motherboard off the shelf The length of the iPhone is 14.6 centimeters Now we need to split it in half I'll put a border on each of them So the actual space of the upper and lower parts It's less than seven centimeters The iPhone's original motherboard battery motor Speaker bar cable and all the internal components They all need to be rearranged We tried a number of schemes over and over again Finally, the decision was made to reverse the entire internal structure That is, the main components such as the motherboard On the bottom half of the fold-out body And the battery goes in the upper half of the body Because custom batteries can change shape More space can be adjusted in the future To lower the larger image sensors The iPhone's dual-layer motherboard design Even though I could save some space But because we don't want to lose the shine of the iPhone The Taptic Engine, for example And a 5W charge Once you've identified the general features you want to keep Custom wiring is also required The motherboard move will make all The component cable has changed.
Procedure Like an inverted battery camera The original cable can not be connected to the motherboard This requires us to customize special FPC flexible wiring And to the manufacturer for proofing This time we are also on the enclosure of the machine Modeling and material selection were carried out Convenient for later 3D printing The next step is to assemble and adjust the position Remodel and print and remodel Then the positioning and the design went back and forth The process is hard and exciting Until it looks like this How do you add tech aesthetics The process is hard and exciting Until it looks like this So after a year of unremitting efforts And trial and error Created by the tech Aesthetics team The world's first foldable iPhone Born at last You can actually tell It was a pretty rudimentary prototype How would you rate it out of 100 Make the foldable phone really work Hardware alone is not enough We don't want a foldable iPhone It's just a decoration We want to reinvent iOS It also makes iOS fold up First, the original iOS It doesn't seem to make any sense in the folding state, right Round iOS ICONS full screen gesture operation A list of information flows in the repository All of this in the folded state Can be presented very well In fact, the operation feel is not bad But when we open the software It doesn't feel right iOS was designed by Apple for straight-screen phones So after the system folds The camera interface is completely distorted and unusable This is true in many software interfaces So we started exploring again Many new renovation schemes The following effects have been achieved so far The revamped iOS can now fold and split the screen The top of the screen can be viewed Photos can be viewed at the bottom of the screen It's more efficient and intuitive It's natural for a foldable iPhone to navigate around the car Hey Siri take me to the airport Getting directions to Taiping International Airport The foldable iPhone could also be used as a selfie holder in the future It's very convenient You can also switch between the top and bottom screens It's very smooth And of course you can have meetings on the screen The bottom screen is also open The leaders are assigned jobs Now discuss with your girlfriend who will cook dinner tonight But you don't want to get it backwards They give their girlfriends jobs Now discuss with your boss who will cook dinner tonight How do you like the new iOS Makes the foldable iPhone even better The Floating plugin is used Landscape split-screen can also be smooth You can play it on the iPhone Split screen effect like iPad This is what the aesthetic of technology has been working on for almost a year There were times when I wanted to give up Burning money is one thing It's mainly one technical problem after another It's really hard to build a product Our initial idea was to build one A foldable iPhone for everyday use But when we actually made it, we realized To face another great difficulty Many features were forced to go Like a hinge because of a shaft of rotation It takes up 11 millimeters of longitudinal space So we ended up having to customize one piece 1000mAh small battery Its standby time It's also the shortest iPhone of all time It's hard to last a day The iPhone's original screen was flexible But it's not strong enough to withstand repeated bending Although we're already in the rotation part Leave as much space as possible There are also gaps when folding But after a few days of use You'll still have horizontal creases and bubbles that can't be fixed Close up and the whole screen is damaged In fact, we went to great lengths The first screen was ready in just a few days There is a leakage of fluid Line the bottom of the iPhone screen It's a single molding sheet with a very thin structure In the process of disassembling and rearranging Prone to failure A deviation of a few tenths of a millimeter during installation The screen will be disconnected, resulting in failure Is that why we disassembled it The reason for all the screens Folding, on the other hand, requires repeatedly bending and moving the screen This leaves the bottom line of the screen on the verge of damage at any time The displacement of the motherboard causes the inside of the fuselage The cable needs to be rerouted Apple's original line is very short And it can't be bent at a large Angle At present, we have re-customized the wiring But its yield is low and its durability is poor Wireless charging has to be removed due to thickness limitations Leave space above the body for batteries So you can only keep one side of the speaker That's all for this foldable iPhone A sorry place Although it took more than 200 days of effort And at great cost But the aesthetics of science and technology can present you It's still a very rudimentary thing So we named it version 0.1 In the days to come We want to continue to improve The foldable iPhone Especially if I need your help If you have any ideas for improvement Or you may be an industry expert Your comments are welcome Even if it's a wild idea Maybe the next version of the fold-out iPhone It's got your idea in it Ok, so that's the whole process I'm excited about the world's first foldable iPhone Can be born in the aesthetics of technology Now that you're here, hit a like Pay attention to us You can see the next one we're building Maybe a better foldable iPhone This is tech aesthetics and I'm NaYan I look forward to seeing you on our next show Apple says come to work tomorrow
