Abstract
Emissive displays require high-efficiency linear drivers which are stable under electrical stress and can deliver uniform performance across a large area. Owing to their low saturation voltage and flat saturation characteristic, source-gated transistors (SGTs) are ideally suited to act as power-efficient driving transistors in active matrix backplanes for lighting, low-power signage and display screens. It is shown that SGTs are also very stable during electrical stress. The technology is compatible with standard TFT fabrication allowing FET and SGT devices to be integrated in the same design and fabrication run.
