What Exactly Are Foldable Smartphones?
Foldable smartphones are like magic books in the palm of your hand—devices that can transform from a compact phone to a larger tablet with just a fold. Imagine carrying around a device that can be both a phone and a tablet, all in one sleek package! These devices have been in the works for years, with concepts dating back as early as 2008 and 2013.
The First Generation: A Leap Forward or Just a Step?
When the first commercially available folding smartphones hit the market in November 2018, they were seen as a leap forward. But like any new technology, they faced some growing pains. The initial models, with their ‘InfinityFlex’ displays and smaller cover screens, were met with concerns about durability and high prices.
From Clamshell to Infinity
The first generation of foldable smartphones came in two main forms: vertically-folding devices that opened like a tablet and horizontally-folding designs that resembled the old clamshell phones. The prototype used a booklet-style layout, with an ‘InfinityFlex’ display inside and a smaller cover screen on the front for quick access when closed.
From Prototypes to Reality
As time passed, more companies got involved in the foldable smartphone game. Xiaomi showed off its prototype in 2019, while Samsung unveiled the Galaxy Fold at Mobile World Congress. LG and Motorola also expressed interest, with LG showcasing a dual-screen case and Motorola filing patents for horizontal folding smartphones.
Quality Concerns and Delays
The launch of the Galaxy Fold faced some quality concerns, leading to delays by Samsung and Huawei. These issues highlighted the challenges in making foldable screens durable enough for everyday use. Despite these setbacks, new devices continued to be released, including the Razr 2020, Mate Xs, Mi MIX Fold, OPPO Find N, Vivo X Fold, Xiaomi MIX Fold 2, Galaxy Z Fold 3, and Galaxy Z Flip 3.
The Future of Foldables
One of the most exciting developments is the Huawei Mate XT, which was released in September 2024. This device takes foldable technology to a new level with its double-folding or tri-fold design, offering even more versatility and functionality.
The Technology Behind Foldables
Foldable smartphones use flexible plastic OLED displays instead of traditional glass screens. While Corning’s Willow Glass is being developed as a flexible glass product, it may not be suitable for electronic displays due to the salt solution used in its manufacturing process.
Improving Durability
Samsung’s Galaxy Z Flip features 30 μm-thick ‘ultra-thin glass’ with a plastic layer that enhances flexibility and durability. However, even this innovative design faced challenges during testing, as it was scratched using a Mohs rating of 2 pick.
Conclusion
Foldable smartphones have come a long way since their early prototypes. They represent the future of mobile technology, offering users the best of both worlds: the convenience of a compact phone and the versatility of a tablet. As technology continues to evolve, we can only imagine what new innovations will bring to this exciting field.
