Samsung talks about "Galaxy Z Fold2" display glass and hinge device

Samsung Electronics announced the launch of the latest model of foldable smartphone "Galaxy Z Fold2" at the recital "Galaxy Unpacked" held on the 5th. Therefore, we introduced the new ideas that the company has made regarding display glass and hinges.

"This glass bends. It's thinner than human hair."-The "Galaxy Z Fold 2 display glass. It has a five-layer structure including a protective layer on the surface." The display glass is said to have both the conflicting elements of strength and flexibility.

On the other hand, as for the hinge, the design that can be left open with any accuracy is adopted like the vertically folded type "Galaxy Z Flip". Inside the hinge, the two pieces slide up and down with each other, but the friction between the pieces allows them to stand at an angle. More than 60 parts, including the cam, move together within the hinge.

On the other hand, the problem was the gap in the hinge part. In the presentation, we will introduce the state of YouTuber testing with sand on the predecessor model. Then, this time, after trying more than 100 ideas, I finally arrived at a mechanism called "Sweeper".

This was inspired by the commercials of vacuum cleaners, and since the carbon fiber and nylon fiber brushes used in vacuum cleaners have sufficient durability and elasticity, they are cut to a short length of 0.87 mm and then the hinge part. Will be built into. The "Galaxy Z Flip" also uses a brushed hinge, which is now 25% shorter in size.
