Abstract: Provided are a display device and a driving method thereof. In the display device, a display panel has multiple pixels. A scan driver provides multiple scan signals to the multiple pixels. During a scan period, the scan driver scans a scanned pixel according to the scan signals, and a source driver provides a source driver signal to the scanned pixel according to display grayscale level of the scanned pixel. The source driver sets a voltage peak value of the source driver signal according to display grayscale level of the scanned pixel. Display grayscale level of the scanned pixel is negatively correlated with the voltage peak value of the source driver signal. Alternatively, the source driver sets a duration of the source driver signal according to display grayscale level of the scanned pixel. Display grayscale level of the scanned pixel is negatively correlated with the duration of the source driver signal.
