Abstract
The present invention provides a driving circuit including multilevel cascading driving sub-circuits, wherein an Nth level driving sub-circuit includes a pull-up potential generating unit, a driving signal generating unit, a pull-down potential generating unit, and a driving signal pull-down unit. The driving circuit provided by the present invention separately outputs a display driving signal and fingerprint driving signals in a different timing through the driving signal generating unit, so that fingerprint driving circuits are not required, thereby reducing size of border regions occupied thereof.
