When the meta-display is stretched lengthwise, it is also stretched widthwise at the same ratio, so that the displayed image can be expanded without distortion. Credit: The Korea Institute of Machinery and Materials (KIMM)
The Korea Institute of Machinery and Materials (KIMM) has successfully developed the first stretchable meta-display technology that can be stretched up to 25 percent without image distortion. The results are published in Advanced Functional Materials. The Department of Nano-Mechanics at KIMM has been researching the field of micro-LED transfer technology since 2008. This was achieved by using the design and manufacturing technology of metamaterials with unique mechanical properties that do not exist in nature.
Most stretchable materials in nature, such as rubber, demonstrate shrinkage in width when stretched lengthwise, thus resulting in image distortion. This was also the same in cases of the rubber-based stretchable displays.
