A pixel unit and driving method thereof are disclosed. The pixel unit includes a switch, a storage element and a first multiplexer. The switch develops a charge transfer path according to a scan signal associated with a scan line. The storage element has a first electrode coupled to the switch and a second electrode coupled to a reference voltage for receiving a pixel voltage via the charge transfer path. The first multiplexer is coupled to the second electrode of the storage element for selectively providing the reference voltage with a default value and the reference voltage with a determined value to the second electrode of the storage element according to a modulating signal. The driving method enlarges the voltage range of the first electrode of the storage element for enhancing the contrast ratio of the display panel.
