Abstract
A driving circuit includes a first transistor having a first terminal, a second terminal and a control terminal; a second transistor having a first terminal connected to the second terminal of the first transistor and a second terminal connected to an organic light-emitting diode; a third transistor having a first terminal connected to the control terminal of the first transistor; a fourth transistor having a first terminal connected to the first terminal of the first transistor; and a fifth transistor having a first terminal connected to the second terminal of the second transistor. The first transistor, the second transistor and the fourth transistor are low temperature poly-silicon transistors, and the third transistor is an oxide semiconductor transistor.
