Abstract:
1. A pixel circuit for liquid crystal display for lowering power consumption via combining an analogue and a digital circuit, the circuit comprises: a plurality of multiplexers, acting as switching elements for performing a plurality of output voltage transforming functions, said plurality of multiplexers comprising a first multiplexer and a second multiplexer; a thin film transistor, for connecting a scanning line and a data line, acting as a control switch of the circuit; and a capacitor, connecting to the thin film transistor, where analogue or digital signals from the data line are stored, wherein said second multiplexer further comprises: a selection terminal; an output terminal; a first mode terminal; and a second mode terminal, said first mode terminal further connects to the capacitor and the thin film transistor, and wherein the second mode terminal further connects to the output terminal of the first multiplexer.
