Abstract

The present application proposes a display device and a driving method thereof. The display device includes a display panel and a driving control module. The display panel includes first data lines and second data lines. The driving control module controls each of the first data lines and each of the second data lines to output a first data signal and a second data signal. A high electric potential period of the first data signal is within a low electric potential period of the second data signal. A high electric potential period of the second data signal is within a low electric potential period of the first data signal.
