Abstract:
1. A pixel located on an i-th horizontal line of a plurality of horizontal lines, where i is a positive integer and each of the horizontal lines includes a scan line and an emission control line, the pixel being coupled to the scan line of an (i−1)-th horizontal line of the horizontal lines, the scan line of the i-th horizontal line, the emission control line of the i-th horizontal line, and the emission control line of an (i+1)-th horizontal line of the horizontal lines, the pixel comprising: an organic light emitting diode having a cathode electrode coupled to a second power source, an emission of the organic light emitting diode being controlled by an emission control signal supplied to the emission control line of the i-th horizontal line; a fourth transistor for controlling an amount of current flowing to the second power source from a first power source via the organic light emitting diode; a first capacitor having a first terminal coupled to a gate electrode of the fourth transistor; a first transistor coupled between a second terminal of the first capacitor and a data line, and configured to turn on in response to a scan signal supplied to the scan line of the i-th horizontal line; a second transistor coupled between the first terminal of the first capacitor and an initial power source, and configured to turn on in response to a scan signal supplied to the scan line of the (i−1)-th horizontal line; and a third transistor coupled between the second terminal of the first capacitor and a reference power source, and configured to turn off in response to an emission control signal supplied to the emission control line of the (i+1)-th horizontal line.
