Abstract

An exemplary liquid crystal display includes a liquid crystal panel having a plurality of pixel units arranged in rows, a scanning circuit configured to activate the pixel units row by row by outputting a plurality of corresponding scanning signals, a data circuit configured to provide data voltage signals to the activated pixel units, and a common voltage circuit. Each pixel unit includes a coupling member. When a row of pixel units is activated, all the coupling members in the row of pixel units cooperatively generate a coupling signal according to the data voltage signals applied to the activated row of pixel units, and superpose the coupling signal to the corresponding scanning signal so as to form a feedback signal. The common voltage circuit adjusts a reference voltage signal according to the feedback signal, and provides at least one common voltage signal to the pixel units.
