Foldable screens use flexible OLED technology

A foldable screen uses a flexible OLED panel that can be folded thousands of times while maintaining its functionality. This technology enables smartphones to change their shape depending on how they are used. Samsung has played a major role in popularizing this innovation through its Galaxy Z series.

OLED technology allows flexibility

OLED screens are particularly suitable for foldable devices because each pixel emits its own light, eliminating the need for a separate backlight. This design allows for thinner and more flexible panels. These screens consist of multiple layers, including an OLED panel, a touch layer, a protective film, support layers, and a hinge that guides the folding movement.

Design challenges for foldable screens

Creating a foldable screen involves more than simply bending a traditional screen. The entire structure must be engineered to handle repeated folding without compromising display quality or durability. Samsung leverages its expertise in display technology, working on all components from the panel to the hinge.

Materials and structure enable flexibility

The flexibility of foldable screens comes from the materials used, particularly the thin OLED panel. However, each fold applies forces across multiple layers, which the hinge helps manage. The external protection must be both flexible and durable to withstand daily use while allowing the screen to bend.

Different models offer varied formats

Samsung's Galaxy Z Fold and Galaxy Z Flip use foldable screens but in different ways. The Z Fold unfolds like a book, offering a larger screen for tasks like multitasking or reading. The Z Flip folds compactly, making it easier to carry. Both models highlight how foldable screens can adapt to user needs.

Visible folds and durability

The visible fold on some screens marks where the panel changes shape. Manufacturers are working to make this transition less noticeable. Durability remains a key concern, as these devices must withstand frequent folding without damage.

Foldable screens enhance user experience

Beyond their visual appeal, foldable screens provide practical benefits by allowing devices to change shape based on usage. A Galaxy Z Fold can function as a regular smartphone when closed but offers a larger screen for activities like watching videos or multitasking. The Galaxy Z Flip offers a more compact form when folded, making it easier to carry.

Integration with software and ecosystems

Samsung is also developing software features like Galaxy AI to enhance the foldable experience. These innovations allow the interface to adapt to the screen's format. Through SmartThings, Samsung connects foldable smartphones to a broader ecosystem of devices, making them a central part of daily life.
