Pixel and organic light emitting display using the same |
摘要 |
A pixel (142) includes an organic light emitting diode (OLED), a first driver (146) and a second driver (148). The second driver (148) controls an amount of current supplied from a first power source (ELVDD) to the organic light emitting diode (OLED), corresponding to a previous data signal. The first driver (146) stores a current data signal supplied from a data line (Dm) and supplies the previous data signal to the second driver (148). In the pixel (142), the second driver (148) includes a sixth transistor (M6) coupled between an initialization power source (Vinit) and a first node (N1) coupled to a gate electrode of a first transistor (M1), the sixth transistor (M6) being configured to turn on when a first control signal is supplied to a first control line (Cl1); and a seventh transistor (M7) coupled between the first power source (ELVDD) and a second node (N2) commonly coupled to the first and second drivers (146, 148), the seventh transistor (M7) being configured to turn on when the first control signal is supplied. |
