The project explored the low temperature, maskless digital fabrication of organic thin-film transistors (OTFTs) on large area rigid and flexible substrates used in flexible display backplanes.
During the manufacturing of OTFT backplanes, defects can occur at a number of different stages and can be caused by anomalies, such as contamination and thickness variations in the conductive and semi conductive layers. Defects are highly detrimental to the performance of the backplanes.
