Displayer and driving method thereof

The invention discloses a displayer and a driving method thereof. The displayer comprises a first scanning line, a second scanning line, a third scanning line, a data line and a first pixel, wherein the first pixel comprises first sub-pixel, a first switch, a second sub-pixel, a second switch, a lower color cast circuit, a lower color cast switch and a dark space forming circuit. The first sub-pixel comprises a first sub-pixel electrode; the first switch receives a second scanning signal of the second scanning line to electrically couple the data line with the first sub-pixel electrode; the second sub-pixel comprises a second sub-pixel electrode; the second switch receives the second scanning signal of the second scanning line to electrically couple the data line with the second sub-pixel electrode; the lower color cast circuit comprises a compensation capacitor; the lower color cast switch receives a third scanning signal of the third scanning line to electrically couple the compensation capacitor to the second pixel electrode of the second sub-pixel selectively; the dark space forming circuit receives a dark space forming signal to electrically couple the first sub-pixel electrode or the second sub-pixel electrode with a universal potential node selectively.
