Imagine this situation. You are enjoying your favorite show on your phone while standing on a crowded train during rush hour. When you get closer to your destination, you just need to fold the phone and easily store it in your pocket without worrying about the screen size and durability. These are some of the real advantages of the smart display technology developed by Samsung that has now not only revolutionized the way we interact with devices but has become part of our fast-paced modern lifestyle.
How Was the Technology Realized?
Although the development process was challenging, this achievement is not impossible. Through deep research, continuous development, and huge investments in innovation, Samsung has succeeded in creating advanced display technology that is now the basis of various smart devices, including foldable devices.
Flexible OLED
With expertise in the field of smart displays and electronic engineering, Samsung has revolutionized the landscape of the global mobile device industry. It all started with the introduction of Flexible OLED technology, a display that can be bent without compromising on visual quality. What was once considered a futuristic concept is now the mainstay of various latest device models.
Flexible OLED
Samsung has once again set a new benchmark by introducing a mobile OLED panel equipped with a built-in fingerprint reader and heart rate sensor. Known as OLED Sensor, this technology is capable of detecting biometric data such as fingerprints and blood pressure directly through the screen surface. It combines advanced optical and digital sensor technology to make the screen smarter, not just for display, but also as a future interactive platform.

At the same time, Samsung also pioneered the development of Rollable Flex technology, a rollable display that can be resized according to user needs. This technology allows a device to be used in various situations, whether as a small portable display or a large display for work tasks. The combination of these innovations proves that Samsung has not only successfully overcome technical challenges but also continues to strengthen its position as a global leader in the display technology industry.
Rollable Flex
The OLED display developed by Samsung is based on the principle of organic molecules that emit light when an electric current flows through them. Each pixel functions as a self-contained light source, and unlike LCD displays that require backlighting. This uniqueness allows OLED displays to be designed thinner, more energy-efficient, and capable of producing high-quality visuals including deep contrast and brighter, more vivid colors
Thin-Film Encapsulation
One of the key challenges in the development of Flexible OLED is the need to protect organic materials from exposure to oxygen, moisture, and other elements that can damage them. To address this issue, Samsung developed a thin-film insulator (Thin-Film Encapsulation) combined with a polymer substrate such as polyimide.
In the context of chemistry, a substrate refers to a material, compound, or ion that undergoes a chemical reaction. As a result, the display can be bent thousands of times without affecting its functionality or visual quality.
Ultra-Thin Glass
To ensure that foldable devices perform optimally and are durable, Samsung introduced Ultra-Thin Glass (UTG) technology. This ultra-thin glass, less than 100 micrometers thick, is strong enough to protect the display while maintaining visual sharpness. Combined with high-quality micro-hinges tested to withstand over 200,000 folds, this technology can ensure that the stability of the display and user comfort are not compromised even after repeated use.
The Mobile Display World Revolution Begins
Rollable Flex opens a new chapter in the world of mobile display technology. With the ability to mechanically extend and shorten as needed, it introduces a more flexible dimension of use. This feature makes Rollable Flex versatile from compact-sized smartphones to large-screen tablets, thus ready to revolutionize various smart devices in the future.

At the same time, the OLED Sensor display not only functions as a visual medium but also acts as a smart biometric tool. It is capable of detecting the user's blood pressure and fingerprint through Photoplethysmography (PPG) technology, a safe optical technique that does not require any physical procedures that penetrate the body. It is also widely used in research and monitoring of heart rate which is closely related to changes in blood volume.

Meanwhile, touch sensors allow the phone screen to help maintain the user's health. This technology allows Samsung devices to be used in smart medicine and health applications. By incorporating smart sensors into the screen, Samsung turns the phone into not just a communication tool but a portable tool for personal and easy-to-use health monitoring.
Key Supplier of Leading Brands
Samsung's success does not only depend on its own product development. Through its subsidiary, Samsung Display, they also play an important role as a key supplier to leading technology brands such as Apple, Oppo, and OnePlus.
OPPO Find N5
For example, the iPhone Pro model uses Samsung's OLED display due to its high energy efficiency and smooth refresh rate. At the same time, OnePlus and Oppo have chosen Samsung’s Flexible OLED displays for their flagship devices to ensure the best visual quality. This market dominance is supported by Samsung’s ability in large-scale production, efficient thin-film transistor (TFT) design, and high display durability including burn-in resistance, making the company the leading choice in the global digital display industry.
Samsung Galaxy S25 Ultra
Even more impressive is the durability of Samsung’s display, which has been proven to perform well in extreme conditions. Several reports claim that the Galaxy S25 Ultra device is able to absorb the impact of metal fragments in armed situations and provide protection to its users. In fact, there are reports that the Galaxy S20 has withstood bullets and acted as a life-saving physical barrier.
These incidents highlight the importance of using high-quality materials such as titanium and polymer composites that are not only durable but also offer additional protection in unexpected situations.
Conclusion
Samsung has transformed the digital display landscape in the modern world through a combination of material engineering, quality design and smart functional integration. Through their commitment to research and implementation of cutting-edge technologies, they have not only driven a revolution in consumer technology but also set new standards in terms of safety and the daily experience of today’s consumers.
