Patent ID: 7773054

Claim:
A pixel comprising: a first capacitor connected between a first node and a second node; a second capacitor connected between the first node and a third node; a first switching device connected between a data line and the first node, and for selectively delivering a data signal to the first node; a second switching device connected to the second node, and for selectively delivering a first power of a first power source to the second node; a third switching device connected to the first node and the third node, and for selectively delivering a voltage at the third node to the first node; a fourth switching device connected to the third node, and for selectively delivering a second power of a second power source to the third node, wherein the fourth switching device is configured to be turned on at substantially a same time as when the second switching device is configured to be turned off, and to be turned off at substantially a same time as when the second switching device is configured to be turned on; a driving device connected to the second node, and for causing a driving current to flow in response to a voltage at the second node; and a light emitting device connected to the driving device, and for emitting a light in response to the driving current flowing into the light emitting device.
