Samsung Z Fold 2 features upgraded hinge

Foldable Phones
[MUSIC] After rigorous tests, the Z42 display is now ready to provide a premium look and upgraded usability. Before display like this to open and close properly, you need a pretty complicated mechanism. This hinge to is constantly being improved. It has a more firm snap To placing it flat and then unsnapping it from flat, You can stand it up like this in this thing they call flex mode. What will the next one be like?>> We designed the Z fold to to stay open at multiple angles like the Z flip. What makes this possible is the cam mechanism. Here's how it works. This is a cam. These two rich shaped pieces slide up and down against each other and the friction created here allows the device to free stand at different angles. Together with larger screens, the new hinge creates many new user scenarios. z flip is long and narrow, while z full two is large and wide. [SOUND] A larger and more solid display needs even stronger power in the hinge. To create that strength, we decided to double up the cam and elastic components including the cam There are over 60 components in the hinge all moving in unison but for them to have space to move. There must be a gap. Ben, so if you get this phone, it might be a good idea to vacuum out your pockets every morning before you put on your pants. [MUSIC] To sweep away these worries, we tried out over a hundred different ideas. The 99th try gave us a starting point for a solution. On the 100 and 8 try, we invented what we now call the sweeper. Interestingly enough, we got the idea from a vacuum cleaner commercial. We found out these machines use bristles made up of carbon and nylon fibers and can rotate 20 times per second for two years. These fibres were elastic and durable enough to be placed under the hinge sweeping through it with every move. Thanks to the upgraded cutting technology, the sweeper became even smaller and is [UNKNOWN] The moment all these innovations come together is when it's finally in the users hands. Providing a whole new experience along with strength and a sense of security.
