Abstract:
1. A pixel circuit for a liquid crystal display using a static memory for lowering power consumption by combining an analog and a digital circuit, wherein the circuit comprises: a first multiplexer, having a plurality of current switching elements; a demultiplexer, having a plurality of current switching elements; a static memory, connecting to a scanning line connected to the first multiplexer and the demultiplexer, for storing the digital voltage signals stored in the demultiplexer; a thin film transistor, for connecting a scanning line and a data line, acting as a control switch of the circuit; a capacitor, connected to the thin film transistor, where analog or digital signals from the data line are stored; and a switch device, connected to the first multiplexer, the demultiplexer and a liquid crystal unit.
