What Are Foldable Smartphones?
Foldable smartphones are like magic wands of technology, transforming from a compact pocket gadget into a larger screen powerhouse. Imagine carrying around a tablet in your back pocket – that’s what these devices promise to do! The concept dates back to 2008 and 2013, but it wasn’t until November 2018 that the first commercially available folding smartphones hit the market.
How Do They Work?
Foldable smartphones can fold vertically or horizontally. The magic lies in their flexible displays or multiple touchscreen panels connected by a hinge, allowing them to change shape like a book opening up. These devices use plastic OLED displays rather than glass because they need to bend without breaking.
Early Challenges and Innovations
The first generation of foldable smartphones faced significant challenges, including durability concerns and high prices. However, as time passed, companies like Samsung, Huawei, Motorola, Xiaomi, OPPO, Vivo, and others continued to innovate, releasing their own versions with improved features.
A Journey Through Time
From 2019 onwards, the landscape of foldable smartphones began to take shape. In that year, Samsung unveiled its Galaxy Fold during Mobile World Congress, alongside other notable releases like Huawei Mate X and TCL’s DragonHinge technology. Motorola also received patents for a horizontal folding smartphone and released the Razr in April 2019.
However, not all launches were smooth sailing. Huawei delayed the release of its Mate X due to concerns over Samsung’s Galaxy Fold. Despite these challenges, the industry continued to grow, with more devices hitting the market each year:
- 2020: Huawei Mate Xs and Samsung Galaxy Z Fold 2
- 2021: Huawei Mate X2 and Xiaomi Mi MIX Fold
- 2022: Samsung Galaxy Z Fold 3, Samsung Galaxy Z Flip 3, OPPO Find N, Vivo X Fold, Xiaomi MIX Fold 2
- 2022 (August): Samsung Galaxy Z Fold 4 and Galaxy Z Flip 4, Motorola Moto Razr 2022
- 2023: Motorola Mobility announced new Razr models for the US market.
- 2024: Huawei is set to release its Mate XT, a double-folding or tri-fold foldable smartphone with an innovative design that could offer a desktop PC-like experience when paired with a case and keyboard.
The Technology Behind Foldables
These devices typically use flexible plastic OLED displays rather than glass. Plastic is more bendable, allowing the phone to fold without breaking, but it’s also more prone to scratches and blemishes. To address this, companies like Samsung have developed ultra-thin glass with a plastic layer and special materials to ensure consistent hardness.
Corning’s Willow Glass is another interesting development in this space. It’s a flexible glass product that could potentially be used in smartphones, but its manufacturing process requires a salt solution which can damage the transistors used in OLED panels. Samsung claims their Galaxy Z Flip uses 30 μm-thick ‘ultra-thin glass’ with a plastic layer and special material to achieve consistent hardness.
Conclusion
Foldable smartphones are not just about the technology; they’re about redefining how we interact with our devices. As these devices continue to evolve, they promise to bring us closer to the seamless integration of technology and everyday life. The journey from 2018 to 2024 has been filled with challenges and innovations, but one thing is clear: foldable smartphones are here to stay.
