Flexible bezel-less micro-LED displays are developed on polyimide film substrates using through-plastic vias (TPVs). Mask misalignment in the TPV formation process is reduced by accounting for substrate shrinkage. The developed displays provide clear moving images with video signals input from the substrate back side through the TPVs.
