Title: SCANNING DRIVING CIRCUIT AND DISPLAY PANEL WITH CHARGE SHARING
Abstract:
The invention discloses a scanning driving circuit (1) and a display panel (2)with charge sharing. The scanning driving circuit (1) comprises a driving unit (10), which receives upper stage scanning signals (Gn-1), present stage clock signals (CKn) and lower stage scanning signals (Gn+1) and generates present stage scanning signals (Gn); a pull-down maintenance unit (20), which pulls down a pull-down control signal point of the driving unit (10); and a sharing unit (30), which receives a first clock signal (SCK1), a second clock signal (SCK2), a first voltage signal (VCS1) and a second voltage signal (VCS2) so as to control the potential of the rising edge and the falling edge of the present stage scanning signal (Gn) through the first and second clock signals (SCK1, SCK2) and the first and second voltage signals (VCS1, VCS2), so that the offset voltage is reduced, the cost is thus reduced and the quality of the display panel (2) is further improved.
