Patent ID: 8054250

Claim:
A pixel of a display having columns of pixels, the pixel in a first column of the columns and coupled to a first scan line, a second scan line and a third scan line, the pixel comprising: an organic light emitting diode; a first transistor configured to be turned-on when a scan signal is supplied to the first scan line for transferring a data signal; a second transistor configured to allow an electric current corresponding to the data signal to flow from a first power supply to a second power supply through the organic light emitting diode; a second capacitor disposed between the first and second transistors, and configured to be charged with a voltage corresponding to a voltage drop of the first power supply and a threshold voltage of the second transistor; a first capacitor coupled between the second capacitor and the first power supply, the first capacitor being configured to be charged with a voltage corresponding to the data signal; a fourth transistor coupled between a second electrode of the first transistor and a reference power supply, the fourth transistor being configured to be turned-on when the scan signal is supplied to the second scan line; a third transistor coupled between a gate electrode and a second electrode of the second transistor; and a fifth transistor coupled between the gate electrode of the second transistor and the reference power supply, the fifth transistor being configured to be turned-on when the scan signal is supplied to the third scan line; wherein the second scan line is a previous scan line of the first scan line and the third scan line is previous scan line to the second scan line, wherein the second scan line is coupled to a second pixel that is selected prior to the pixel, the second pixel in the first column, and wherein the third scan line is coupled to a third pixel that is selected prior to the second pixel, the third pixel in the first column.
