Why is it difficult to produce a folded - screen phone?

Smartphone producers need something that can shake the market and make many believe that folding phones are the future.

Small changes as hardware updates have failed to generate enough interest, as has happened in the past, what has caused the sale of companies like Apple and Samsung to be blocked in the country.

Some popular smartphone producers have thus begun to create luxury telephones with more advanced folding than their capators. These phones can be opened on the tablet.

But converting a folding screen from the concept into a device that really works has proved to be a separate engineering challenge.

Samsung first started on the phone Galaxy Fold, which cost 2,000 dollars. Some reports that had access to these phones found that the axis had problems and that the screen broke after a glass was removed.

Samsung responded by delaying the debut predicted on April for an indefinite deadline. Huawei Mate X, the next salt price and folding screen phone will debut no sooner than September.

Apple, on the other hand, has applied for some patents for folding phones but is still away from presenting a device.

A Kriative Strategic analyst, Ben Bayari, said folding screens create scientific problems with his material. First, light issue diodes should be created that allow for nondegradable pixels and the creation of an axis that does not harm the screen.

Also, the question is how the battery will be placed on it, whether it will fold on the screen or not. But the real challenge is the screen.

Samsung and Huawei use a protective screen consisting of plastic polymers. These polymers are so flexible that they allow screen folding but not as resistant as glass and can easily scratch.

plastic can also form wrinkles and distort without breaking. The plastic polymers are the only chance left for the production of folding phones in the short term, but the future remains glass.

The glass can only be distorted at temperatures higher than 600 degrees. “The combination of super thin glass, smaller than the hair of a hair, and high power enabled it to bend without any harm,”, according to Glass Science Professor of Alfred University.

The “will not fold as if it were a piece of paper, but it can fold around a metal vault and go back to flat without causing any scratch.

Smartphones are made of glass that is very strong and flexible. The problem is it's not flexible enough to fold up according to LaCourse.

He predicts that a glass-folding device can become reality in the next two years.

The ideal folding screen should be thick enough to be strong but thin enough to be flexible without using force. “The thicker the glass the greater the strength to bend it,” said LaCourse.

Corning, one of the world's largest smartphone glass producers, creates and produces Gorilla Glass, which is used by several smartphone producers including Apple.

A company spokesman confirmed that they are working to create a thin but resistant glass that can be used on folding screen phones. The company said it succeeded in testing.

“The development of a mosque that can fold hundreds of thousands of times without being damaged or preserving the ability to lie flat is near a reality” according to Corning.

Corning is responsible for some innovations like super thin but powerful, super thin and flexible glass. “technology is going towards new levels but there are still limits,” said LaCourse.

But even the finest glass cannot be folded like a paper coin, although it has advantages over plastic. LaCourse said that even Gorilla Glass has limitations because it can create scratches on the surface.

The first generation of folded-screen phones may be coming, but they're far from perfect.
