An amorphous silicon triode rectifier switching device for active-matrix liquid-crystal display

A triode rectifier switching (TRS) device composed of two amorphous silicon (a-Si) diodes and one resistor has been demonstrated experimentally to be a good switching device for active-matrix liquid-crystal display (AMLCD). The output and transfer characteristics of a TRS are very similar to those of an a-Si thin-film transistor. High on/off current ratio (>5*10/sup 6/) and low off-state leakage currents (<0.4 pA) have been demonstrated with a-Si diodes and a-Si resistor, indicating that the TRS is suitable for highperformance switching devices for AMLCD.
