Foldable Glass: How is it Used in Foldable Phones?

The era of mobile devices keeps changing and improving, evident by the new field of devices being released. Samsung just released its first foldable glass mobile phone that might be the future of mobile device now. In 2019, Samsung released Samsung’s famous Galaxy Fold with the plastic screen, but now they are improved with the glass display. The technology of folding phones is just improving, and it will make a better future of folding devices. Here is everything you need to know about the foldable glass:

Foldable Glass Only Bends Not Totally Folds

A foldable glass of device does not fold totally; in fact, it only bends because both edges of the screen doesn’t touch with each other. You might see that when you close the Samsung Galaxy Z flip device, it does not touch the screen properly and there is a gap between both sides of the display. It indicates that display is only bending but not fully folding like a paper. It’s a fact that foldable glasses are just an ultra-thin glass that can’t break when they bend thousands of times. So it’s just bending from both sides but not completely folding.

Is Bending Glass A New Technology?

Not just Samsung, but many more companies are looking to make folding phones technology. Samsung hasn’t said much about their new technology of the folding device, but it seems like they are dealing with a Korean manufacturing company Doowoo Insys. In the mobile device, most of the companies use Corning Gorilla glass which is hard to bend because of its damage-resistant benefit. But corning glass can also bend if they are the type of Willow glass.

It’s not a new technology used for the first time. Bending glass technology is growing from the last 50 years. For fibres optic cables, corning made plastic glasses that can bend through 90 degrees and work perfectly after that.

Making Of Bendable Glasses in Mobile Devices

It’s a challenge for everyone who is working on making bending glasses for mobile phones. For mobile phones, it requires the thinnest glass and also durable just like gorilla glass. It is true that gorilla glass is durable and damage-resistant. It is easy to make a thin glass, but the challenge comes from durability and damage resistance, and this happens from doing a drop test.

Banding glass companies are claiming that they are working on making durable glass-like corning gorilla and also keeping it bending. It’s a big challenge for the company that is working on it, but every company has a different concept, and most of them don’t prefer to share their methods publicly because now the competition is high.

Reason Why Foldable Glass Is a Major Aspect

Glass is a great material for Smartphone, and Samsung is no more using the plastic display on the folding device. Companies like Motorola Razr, Samsung Galaxy Fold and Lenovo ThinkPad X1 Fold all have a plastic display that seems like the screen protector. These plastic screens are durable, and there is no need to worry for breaking of these screens.

Unlike the plastic screens, glass screens can be damaged but can be scratch resistant. It is the reason most of the Smartphone focus on glass display to look original and for better touch quality. As compared to the plastic display, glass display is much better because using a finger on display doesn’t affect the screen, but the plastic display can be damaged. In current time companies and consumer both prefer to use glass display, and that is why in every innovation of Smartphone, glass display is the priority.
