Claim 0:
1. A display device, comprising:
a display panel, comprising a common electrode and a plurality of data lines; and
a voltage processing circuit, comprising a first input node electrically connected to the common electrode and a first output node electrically connected to at least one of the common electrode and the plurality of data lines,
wherein the voltage processing circuit is configured to obtain a common voltage signal of the common electrode in an nth frame through the first output node, and configured to control a voltage of the at least one of the common electrode and the plurality of data lines in an (n+k)th frame through the first output node in response to a difference between the common voltage signal of the nth frame and a standard voltage, where the n and k are positive integers;
wherein the voltage processing circuit comprises a voltage comparison circuit, which comprises a second input node electrically connected to the first input node, a second output node electrically connected to the first output node, and a third input node loaded with a frame synchronization signal, and the voltage comparison circuit is configured to generate a first target voltage signal in response to the difference between the common voltage signal in the nth frame and the standard voltage on a condition of a synchronization pulse occurring in the frame synchronization signal; and
wherein the voltage of the at least one of the common electrode and the plurality of data lines in the (n+k)th frame is related to the first target voltage signal.
