An exemplary driving circuit includes pixel electrodes ( 362 ) applied with voltage signals (VS) respectively via corresponding switching elements ( 361 ) connected thereto and common electrodes ( 363 ) applied with common voltage signals. Each switching elements includes an input electrode ( 3613 ). The driving circuit further includes at least one comparator ( 40 ) and a common voltage generator ( 34 ). The at least one comparator is configured for obtaining at least one voltage deviation value (DeltaV) between the voltage signal of at least one of the pixel electrodes and the voltage signal of the corresponding input electrode. The common voltage generator is configured for generating a common voltage signal according to the at least one voltage deviation value, and outputting to the common voltage signal to the common electrodes.
