Display device and driving method thereof

A driving method of a display device, comprising:

• providing a display panel having a plurality of pixels;
• providing a scan driver, so that the scan driver provides a plurality of scan signals to the pixels, and that the scan driver scans at least one scanned pixel among the pixels according to the scan signals during a scan period of a display time interval;
• providing a source driver, so that the source driver provides at least one source driver signal to the at least one scanned pixel according to a display grayscale level of the at least one scanned pixel during the scan period;
• and
• causing the source driver to set a voltage peak value of the source driver signal according to the display grayscale level of the at least one scanned pixel, wherein the display grayscale level of the at least one scanned pixel is negatively correlated with the voltage peak value of the source driver signal;
• or
• causing the source driver to set a duration of the source driver signal according to the display grayscale level of the at least one scanned pixel, wherein the display grayscale level of the at least one scanned pixel is negatively correlated with the duration of the source driver signal.
