Abstract
A printed circuit unit implementing with organic transistors is provided. The printed circuit unit includes an input signal circuit, a load circuit and a level shifter. The input signal circuit includes N serially connected organic transistors. When one of the serially connected organic transistors is cut-off, the signal input circuit is cut-off, so that the circuit is maintained to output a correct voltage level. The level shifter circuit includes an organic transistor having a gate for receiving the input signal. The organic transistor can also serve as a load for improving a gain of the level shifter.
