From: Integrated multilayer stretchable printed circuit boards paving the way for deformable active matrix
Deformable LED active matrix realized using SPCB method. The planar a addressable LED matrix can be deformed to different shapes without altering its electrical functionality. The deformation involves deflation (b), inflation (c), 3D guided shapes (d), and vacuum forming (e). The addressability of the array remains unaltered after mechanical deformation (f)
