Abstract
A liquid crystal display (LCD) has a pixel matrix, a plurality of shift registers, a plurality of common voltage generators, a plurality of common voltage buffers, and a plurality of primary bidirectional switch circuits. The shift registers sequentially output gate signals to scan lines of the pixel matrix. The common voltage generators output initial common voltages according to the gate signals. The common voltage buffers are configured to buffer the initial common voltages to output a plurality of common voltages to a plurality of common voltage lines of the pixel matrix. Each of the primary bidirectional switch circuits is configured to control electrical connection between two of the common voltage lines according to one or more gate signals outputted from at least one of the shift registers.
