Patent ID: 8111216

Claim:
A system for displaying images, comprising: a pixel driving circuit, comprising: a storage capacitor comprising a first node and a second node; a transistor comprising a gate coupled to a discharge signal, coupled between the first node and the second node, wherein the transistor is turned on by the discharge signal to discharge the storage capacitor during a first period; a transfer circuit coupled to the first node of the storage capacitor, the transfer circuit transmitting a data signal or a reference signal to the first node of the storage capacitor; a driving element comprising a first terminal coupled to a first fixed potential, a second terminal coupled to the second node of the storage capacitor, and a third terminal outputting a driving current; and a switch circuit coupled between the driving element and a display element, directing the driving element to operate as a diode during a second period and allowing the driving current to be output to the display element during a third period.
