Highly Stretchable LED Display Using Liquid Metal and Molybdenum‐Barriered Multilayer Electrodes with Long‐Term Reliability
Abstract Promising freeform deformable displays require highly stretchable interconnection lines and reliable, low‐resistance connections. To this end, a stretchable light‐emitting diode (LED) display with a molybdenum‐barriered multilayer electrode using liquid metal (LM) alloys with high reliabili...

| description | Abstract Promising freeform deformable displays require highly stretchable interconnection lines and reliable, low‐resistance connections. To this end, a stretchable light‐emitting diode (LED) display with a molybdenum‐barriered multilayer electrode using liquid metal (LM) alloys with high reliability and stretchability under repeated deformations of 12 000 times and long‐term stability over 300 days is introduced. The developed multilayer‐stacked electrode shows consistent and stable stretchable electrical connections with long‐term reliability, even under continuous mechanical deformation. Thus, the developed display with micro‐ or mini‐LED components can be deformed, such as domes and twice folding like a handkerchief. Highly stretchable LM fine lines are developed by printing directly onto the acrylic adhesive layer, which enables high stretchability even under 100% uniaxial strain with a 100 µm narrow width. The stretchable display technology has successfully realized form‐free displays that flexibly deform into 3D shapes for advanced wearable and freeform applications. |
