We report DC driven full color inkjet printed quantum-dots light-emitting devices. The inkjet was used to print monochromatic red, green, and blue, as well as integrate red-green-blue light-emitting quantum dots unto a substrate having QVGA display. The performance of the inkjet printed monochrome devices was on the same order as that of spin coated ones. For the full color RGB devices, a video brightness...
The use of a vertical thin film transistor (VTFT) topology in the flat panel active matrix array, opens up a plethora of new high performance applications. The VTFT is small in footprint by virtue of its stacked layer configuration, in which channel lengths can be conveniently scaled down to nanometer regime without having to resort to photolithography as would otherwise be needed when scaling lateral...
