Hardware and software challenges with creating a collapsible smartphone


The hype is real. You've probably seen and heard rumors about the impending release of a smart folding device. Taking years to develop, design and design, the world's first foldable smartphones have arrived. So what do you think?


You probably have not gone too far in the social media timeline without finding Samsung's new Galaxy Fold device or the sleek new Huawei Mate X. First of all, these phones have attracted the attention of people around the world. However, the response to these devices was mixed.

New or potentially useful innovation? These high-priced "luxury" devices have several features centered around the folding capabilities of each phone, promising to usher in a new era for the smartphone.

Whether you agree with this or not, you have to admit that the engineering behind these phones is impressive, and based on some of the development ideas for these phones, is not easy. You may not like the phones, but you should appreciate the technology and challenges these companies have created to create these phones.

So, hold your phone and take a peek at the software and hardware challenges of creating those devices and any possible challenges that may occur in the near future for users. Who knows, you may gain a new appreciation for these devices.

A continuous experience throughout

Perhaps a little overlooked, creating a device that can seamlessly move from a bent experience to an unfolding experience is not an easy achievement. The UX for these devices needs to be intuitive without breaking the immersion, a big challenge for developers.

You may be playing your favorite game on your foldable device, but then decide you want to unfold the device for a little more actual screen. It will be imperative for application developers to ensure that the user experience does not change from one screen to the other, ensuring that the application provides adequate support for changing the run-time configuration.

At least from the demonstrations of the Mate X and the Samsung Galaxy Fold, both phones seem to work smoothly when transitioning from the folded state. However, it is worth mentioning that the display rates of 21: 9 and 4.2: 3 (Galaxy Fold) are not common in the industry. Creating applications for these proportions will also be a challenge.

Having a display device with multiple windows presented challenges before, just coming into commercial use recently. Android made it possible to support views of multiple windows from more than one application at a time.

Android allows multiple applications to share the screen at once by dividing the screen in three different ways and pausing the screen to ensure that the device does not overload when running multiple applications.

Developers who have the ability to configure applications for multi-window mode let them choose how an application's activities support multi-window mode, including selecting attributes to control size and layout.

It will be interesting to see how developers adapt applications to these screens and how these new folding phones are able to handle multiple applications at once. Further, this is back to the continuity of each device's immersive experience. developers will need to design controls to provide seamless experience.

In short, developers need to think of two things when building applications for devices, screen continuity, and multi-window mode, as this will forcefully dictate the success of these devices in the long run.

The folding display

Now, one of the biggest challenges when creating a bending device is to find or create a high-quality screen that suits a person's desires. Flexible displays have been around for some time in the areas of electronics research. Companies such as Xerox PARC and HP have spent countless hours developing this new technology.

However, the emergence of flexible OLED displays is what enabled Mate X and Galaxy Fold to be possible. On each device, a phone starts with the default screen size and then unfolds to the size of what you can call a mini tablet.

The OLED on these devices is large and vibrant and can rival any other top-level device on the market. However, now that companies know that a foldable device is possible, they need to rethink their uses. Folding phones may not be the future, but folding OLED displays are the future.

Please do not break

Folding. Folding Folding. Unfolding This will happen every day for hours on end. Creating a device that is durable enough to withstand its constant use is a feat in itself. However, how many folds can these phones receive? And will there be special cases on those phones?

Time will tell, but insiders have already pointed to the "inevitable crease" that appears in the devices.

What's more, the OLED screen has a number of benefits compared to traditional displays, such as larger fields of view, better contrasts and better brightness, but these screens are also very sensitive to water and have shorter lifetimes.

To combat these challenges, Samsung's Infinity Flex Display uses a polymer that is said to make the display "flexible and resilient," which means it can maintain its strength even when folded and unfolded "hundreds of thousands of times."
