An exemplary liquid crystal display (200) includes a liquid crystal panel (201) having a plurality of pixel units (240), a scanning circuit (202) configured to activate the pixel units, a data circuit (203) configured to provide data voltage signals the pixel unit via a plurality of data lines (220), and a common voltage circuit (205) configured to generate a common voltage signal. Each pixel unit includes a pixel electrode (242), a common electrode (243), and a coupling member (245). The coupling member is connected between the pixel electrode and a corresponding one of the data lines, and is configured to transfer an electrical potential shift of the corresponding common electrode to the corresponding data line when one of the data voltage signals is applied to the pixel electrode. The common voltage circuit is configured to compensate the common voltage signal according to a feedback signal obtained from the data lines.
