Abstract
A driving circuit includes a current drive unit and a reset compensation and light emitting control circuit. The current drive unit includes a first transistor and a second transistor. The first transistor and the second transistor are connected in series, wherein the first transistor and the second transistor include a silicon semiconductor layer. The reset compensation and light emitting control circuit is coupled to the current drive unit. The reset compensation and light emitting control circuit includes a third transistor connected to a control terminal of the first transistor, wherein the third transistor is an oxide semiconductor transistor.
