Abstract
A level shift circuit includes a control logic circuit, a plurality of level shift output buffers and a plurality of charge sharing circuits. The control logic circuit receives input clock pulse signals and a charge sharing signal and acquires voltage level information of each received signal. Each output buffer amplifies a corresponding input clock pulse signal and determines whether to output a signal according to the acquired information of the charge sharing signal. Each charge sharing circuit determines whether to be turned on according to the acquired information of a corresponding input clock pulse signal. When a charge sharing circuit is turned on, the output terminal of a corresponding output buffer and a predetermined voltage level are coupled to each other by the charge sharing circuit, so as to perform the charge sharing operation. Furthermore, a corresponding liquid crystal display device and a corresponding charge sharing method are also provided.
