Electric charge recovery circulating circuit of display equipment

The invention discloses an electric charge recycle circuit of a display unit used to connect between a display panel and a source drive circuit which are both of a display module, wherein, the display module is provided with the source drive circuit and a gate drive circuit; when the source drive circuit closes, the electric charge recycle circuit transfers the electric charge to a system external capacity. The invention comprises an electric charge transfer circuit and a sense switching element, wherein, the electric charge transfer circuit can transfer the electric charge stored of a parasitic capacitor of the display panel to a system external capacity element to be stored; the sense switching element can sense voltage level between the display panel and the source drive circuit, and the on-state between the electric charge transfer circuit and the source drive circuit is determined according to a luminous critical pressure of the display panel of different color layers. The invention can effectively save
