Description:

AMOLED displays at low gray levels require high SS to control the data potential easily. In this study, we present a high-mobility, coplanar dual-gate (DG) dual-channel TFT, where the SS can be tailored. This approach enables the device to function effectively as a driving TFT, achieving SS of 0.618 V/dec. The proposed DG, dual-sweep (DS) a-IZO/a-IGZTO TFT exhibits µFE of 65 cm²/V.s, VTH of 0.46 V, and on/off current ratio of 10^8.
