Introduction: Samsung’s Stretchable Micro LED Display Technology
On August 21, international reports surfaced that Samsung Display showcased a stretchable Micro LED display at the International Information Display Conference held on Jeju Island, South Korea. The device sets new records for resolution and stretchability among stretchable display products.
Breakthrough Features of Samsung’s Stretchable Micro LED Display
The new display can stretch up to 1.25 times its original size while maintaining a high resolution of 120 pixels per inch (PPI). According to Samsung Display, the screen has a rubber-like texture, making it ideal for creating buttons on flat screens or applying it to uneven surfaces like fabrics, furniture, and buildings, thereby offering novel user experiences.
At the conference, Samsung demonstrated the capabilities of this stretchable display technology by projecting a 3D image of a resort island, showcasing its potential to provide dynamic visual experiences on various surfaces.
Industry-wide Research into Stretchable Micro LED Displays
Notably, Samsung is not the only player in this field; numerous university teams and companies are actively researching flexible and stretchable Micro LED products. For instance, in June, a research group led by Professor Yongtaek Hong from the Department of Electrical and Information Engineering at Seoul National University announced a significant breakthrough in integrating Micro LED technology with flexible and stretchable devices.
Similarly, in April, Stanford University developed flexible and stretchable integrated circuits (ICs) that successfully powered a Micro LED display, opening up new possibilities for health monitoring and disease diagnosis.
In March 2022, Korea’s Institute of Machinery and Materials (KIMM) developed a distortion-free stretchable Micro LED meta-display technology that can stretch up to 25% without compromising image quality.
Corporate Advances in Stretchable Micro LED Technology
In addition to academic research, several companies are advancing stretchable Micro LED technology. Last year, AUO introduced a stretchable Micro LED screen, while LG unveiled a 12-inch stretchable Micro LED touchscreen with a stretchability rate of 20%. These developments signify the increasing focus on flexible and versatile display technologies across the industry.
