“SID Display Week 2025,” the world’s largest display technology event held in San Jose, USA, in May 2025, was a stage where you can directly see the evolution of next-generation form factor technology. In particular, rollable and slidable displays are no longer concepts, but have become technologies that are about to be commercialized as actual products. At the same time, Samsung Display has significantly improved its technological completeness by announcing material technology innovations to solve the structural problems of rollable displays.

Rollable displays have been gaining attention as next-generation displays that simultaneously provide portability and large-screen experiences, with a structure that expands as if the screen is rolled up. At SID 2025 and CES 2025, major global companies drew attention by implementing these into actual products.

Lenovo’s ThinkBook Plus Gen 6 Slidable AI PC, which was commercialized in the first quarter of 2025, is equipped with Samsung Display’s slidable OLED and extends from 14 inches to a maximum of 16.7 inches and has passed durability tests more than 30,000 times.

 At CES 2025, Samsung Display unveiled a prototype of its vertically expanded “Slidable Flex Vertical” smartphone. It is evaluated as a new method that simultaneously provides portability and a large screen experience by sliding vertically from the basic 5.1-inch screen size to a 6.7-inch large screen. There is also interest in whether Samsung will commercialize a Galaxy Rollable Phone based on its own slidable OLED technology in the future.

 At SID 2025, BOE unveiled a rollable OLED prototype that extends from 12.3 inches to 17.3 inches. The product is characterized by an expansion ratio of 4 mm and 3.2:1 in roll radius and has been introduced to have a flexural durability of more than 100,000 times.

 Tianma entered the advanced form factor competition by introducing a 13-inch sliding AMOLED prototype. It was designed with a radius of curvature (R) of 5 mm, the screen can move 70 mm, and it was reported that there was little change in thickness and flatness before and after the slide.

Rollable and sliderable displays still face technical challenges such as durability, uniform resilience, and reliability of the drive mechanism, but structural design and material innovation are emerging as the key to solving these issues.

Samsung Display emphasized the importance of material development, a core technology of rollable displays, by publishing a paper titled “Highly Reversible and Robust Rollable AMOLED Display with Smart Elastomer Materials” at SID 2025. The paper was chosen as the Distinguished Paper for Display Week 2025.

Samsung Display has greatly increased the durability and resilience of rollable displays with its two-layered smart elastomer structure, which is highly elastic and low elastic. Thanks to the new structure, the deformation of the edge of the panel has been significantly reduced even after the pen drop test and repeated rolling. The elastomer layer significantly reduces deformation compared to conventional polyimide and showed excellent recovery even in repeated rolling. Anti-static treatment was added to effectively suppress panel image damage due to repetitive friction and charging.

Rollable and slidable OLED technologies are now entering various product markets such as smartphones, laptops, and vehicle displays beyond the technology demonstration stage.  At the same time, the mechanical stress, durability, external impact and electrostatic accumulation problems they experience cannot be solved without high-performance material technology. The smart elastomer-based double-layer design proposed by Samsung Display presents an answer to these problems, potentially giving the company a technological edge in the premium mobile device and automotive large-format display markets. The next initiative in the display industry will be completed through integrated technology that synergistically combines materials, structures, and processes for design innovation.

Laptop manufacturer Lenovo plans to launch a rollable OLED notebook in 2025, and Samsung Display is expected to exclusively supply the panels.

Lenovo simultaneously exhibited an AI notebook with foldable OLED and an AI notebook with rollable OLED at MWC 2025 held in Barcelona, ​​Spain.

The name of the foldable notebook displayed by Lenovo is ‘ThinkBook codename Flip’, and it has a screen size of 13 inches when folded and 18.1 inches when unfolded. It is very light at 1.4 kg and has a thickness of 16.9 mm.

Lenovo introduced Rollable AI PC as another new product. The name of the Rollable AI PC is ‘ThinkBook Plus Gen 6 Rollable AI PC’ and it is equipped with a rollable display that increases in size from 14 inches to a maximum of 16.7 inches. Both Lenovo products are exclusively supplied by Samsung Display and are scheduled to be released in mid-2025.

Attention is being paid to whether the size of the foldable/rollable notebook market will expand with Lenovo’s entry into the rollable notebook market.

Tianma’s OLED shipments for smartphones were second only to BOE among Chinese makers

TIANMA

It was found that Tianma, a Chinese OLED panel supplier, supplied the second most OLED panels for smartphones after BOE in the first quarter of 2023. In the meantime, among Chinese companies, Visionox has always been in second place after BOE in OLED shipments for smartphones, but it gave way to Tianma for the first time in this first quarter.

Tianma’s major customers include Xiaomi, Vivo, Oppo, Honor, and Lenovo. It is analyzed that one of the reasons for Tianma’s increase in OLED shipments is that it brought some of TCL CSOT’s shipments to Xiaomi.

Thanks to orders from Xiaomi, Tianma’s panel shipments have soared since the fourth quarter of last year. Tianma’s OLED panel shipments for smartphones in the fourth quarter of 2022 increased by about 3 times compared to the previous quarter, and in the first quarter of 2023, OLED panel shipments for smartphones reached 8.5 million units, an increase of 430% compared to the same quarter of the previous year.

If this atmosphere continues, it is analyzed that there is a possibility that Tianma will overtake Visionox and produce the second largest number of OLED panels for smartphones after BOE in China for the first time this year.

Samsung Electronics launched its Windows tablet ‘Galaxy Book 12.0’ in Japan. It has a 12-inch OLED display with an aspect ratio of 3: 2 and a resolution of 2,160 × 1,440. The size is 291.3 × 199.8 × 7.4 mm (WLH), the weight is 754 g, and the official price is 139,800 yen.

Galaxy Book 12.0 was released to the public at MWC 2017, the world’s largest mobile telecommunication exhibition held in Barcelona, Spain on February 26, and was pre-booked in Korea in April. At MWC 2017, a Samsung Electronics official said, “Galaxy book is expected to be able to target both tablet PC and notebook market at the same time, and burn-in phenomenon, which is a weak point of AMOLED panel, has been improved enough to be used for notebook applications.”

OLED, which was mainly applied only to mobile devices and TVs, has recently been applied to tablets and notebooks, widening its application range. In early 2017, Alienware launched the ’13 R3 2017 ‘with 13.3-inch OLED, and Lenovo also released the X1 Yoga 2017, which is powered by a 14-inch OLED in July 2017.

As OLEDs are applied to various applications and become the mainstream of display industry, it will be interesting to see if they can exert their influence in the tablet and notebook market as well.
