Stretchy micro-LED bends, folds and can be shaped into spheres and domes

Royole Corporation demonstrated a micro-LED stretchable display at the 2021 Display Week Symposium, in what it claims is world first.

The display technology, revealed at the Society for Information Display (SID) event held online this month, is compatible with industrial manufacturing processes.

Royole’s stretchable displays are foldable, rollable and capable of 3D free form shaping, including pulling, twisting, convex and concave deformations. They could be used in smart devices where three-dimensional folding could create smaller products, or deployed in dome and spherical shapes.

Dr. Bill Liu, founder, chairman and CEO of Royole, said: “Royole continues to lead in flexible innovation, with stretchable technologies marking the next frontier in technical progress that will enable unprecedented applications and form factors across augmented and virtual reality, wearable electronics, biomedical applications, vehicle design and beyond.”

Royole presented research that showed its micro-LED stretchable display technology is capable of 130% stretchability, convex bending up to 40 degrees, while reaching a resolution up to 120 pixels per inch (PPI), a resolution threshold capable for use in laptop screens. The micro-LED technology additionally allows transmittance up to 70%, much higher than existing flexible OLED technologies, suiting it to use in smart solutions requiring transparency, such as for car windshields or sunglasses.
