Defect identification in large area electronic backplanes

 

We describe a rapid testing system for active matrix TFT backplanes which enables the identification of many common processing defects. The technique spatially maps the charge feedthrough from TFTs in the pixel and is suited for pixels with switched-capacitor architecture.
