Patent ID: 7864145

Claim:
A display unit comprising: a first switch element having a first terminal for receiving a data signal and a second terminal electrically coupled to a first node; a second switch element having a first terminal electrically coupled to the first node and a second terminal electrically coupled to a second node; a driving element having a control terminal electrically coupled to the second node, a first terminal electrically coupled to a third node, and a second terminal electrically coupled to a fourth node; a storage capacitor electrically coupled between the first and third nodes; a third switch element having a first terminal electrically coupled to the second node and a second terminal electrically coupled to the fourth node; a fourth switch element having a first terminal electrically coupled to a first voltage source and a second terminal electrically coupled to the third node; and a light-emitting element electrically coupled between the fourth node and a second voltage source; wherein the first and third switch elements are controlled by a first signal, and the second and fourth switch elements are controlled by a second signal.
