Author : Priyanka | December 24, 2023
Many of us have noticed the emergence of foldable smartphones and TVs. But, have you ever pondered the intricacies of these devices and how they achieve their flexibility? Well, the secret lies in the foldable display technology. In the following discussion, we explained the inner workings of these devices and the innovations contributing to their widespread appeal.
Let's dive in!
What are Foldable Displays?
Foldable displays, or foldable screens, are a type of screen technology that can be bent or folded without damaging the display. They offer a flexible and versatile form factor, allowing devices to have larger screens that can be folded into a more compact size for portability. Displays with foldable technology are typically made using flexible OLED (organic light-emitting diode) technology, which allows the display to be thin and bendable.
Foldable screens are also known as flexible displays. These displays have gained attention in recent years, particularly in the smartphone industry, for their ability to enable devices with larger screens while still maintaining portability. As per a recent report by Kings Research, the global foldable display market is likely to reach $28.33 billion by 2030, growing at a CAGR (compound annual growth rate) of 8% from 2023 to 2030.
Exploring the Pivotal Types of Foldable Displays
Below are the common types of foldable screens widely used in various applications.
- Flexible OLED displays
These displays utilize flexible OLED (organic light-emitting diode) technology. It can be bent, rolled, or folded without damaging the display. Offer thin and lightweight form factors. These displays provide enhanced flexibility and durability when compared to traditional rigid displays. It is widely used in various devices, including smartphones, tablets, and wearables.
- Multi-Fold Displays
These displays can be folded multiple times, both inward and outward. They offer a compact form factor when folded and a larger screen when unfolded. Multi-fold displays improve multitasking and productivity by providing more screen space. Examples of these devices include the Xiaomi foldable display smartphone.
- Clamshell Displays
Clamshell displays consist of two separate displays joined by a hinge. When unfolded, they provide a larger, continuous screen. Microsoft Surface Duo is the best example of these screens, which feature two displays that can be used independently or together.
- Foldable Tablet Displays
A larger, foldable screen is designed for tablet-like experiences. These displays offer the convenience of a larger screen while maintaining portability. They can be folded into a more compact size for easy carrying.
- Foldable Laptop Displays
These screens aim to provide a more versatile computing experience. They combine the functionality of a laptop and a tablet. Foldable laptop displays offer flexible screens that can be folded or adjusted to different angles. A prominent example is a prototype like Intel foldable-screen computer.
- Foldable Display Form Factors
Various designs and configurations of foldable screens include inward fold, outward fold, multi-fold, and clamshell form factors. Each form factor such as size and shape offers unique benefits and use cases. Manufacturers are actively engaged in ongoing innovation and the exploration of novel form factors for foldable displays.
