Abstract

A driving circuit includes: a switch unit operable according to a scan signal, and adapted for permitting transfer of a data signal when operating in an on state; a capacitor having a first end that is coupled to the switch unit, and a second end; a first transistor having a first terminal that is adapted for coupling to a voltage source, a second terminal that is coupled to the second end of the capacitor and that is adapted to be coupled to a load, and a control terminal that is coupled to the first end of the capacitor; and a second transistor having a first terminal that is adapted for coupling to the voltage source, a second terminal coupled to the second terminal of the first transistor, and a control terminal that is adapted for receiving a bias voltage. Each of the first and second transistors operates in the linear region.
