ABSTRACT:
A pixel driving circuit with threshold voltage and EL power compensation. The pixel circuit includes a storage capacitor, a transferring circuit, a driving element, and a switching circuit. The transferring circuit transfers a data signal or a variable reference signal to a first node of the storage capacitor. The driving element has a first terminal coupled to a first fixed potential and a second terminal coupled to a second node of the storage capacitor. The switching circuit is coupled to a third terminal of the driving element and the second node of the storage capacitor. The switching circuit can be controlled to make the driving element diode-connected in one time period and allowing a driving current to be output to a display element in another time period.
