Flexible and mask-free Patterning Process

Laser ablation is used in the production of smart windows, solar panels, organic LED or flat panel displays.

Laser processing enables both precise patterning (e.g. ITO patterning) – beyond limiting scan field sizes – as well as a large area removal (laser ablation) of transparent conductive, semi conductive, organic and metallic layers. Process parameters are tuned to each layer stack and material.
