Pixel and organic light emitting display using the same |
摘要 |
A pixel includes an organic light emitting diode, a first driver and a second driver. The second driver controls an amount of current supplied from a first power source to the organic light emitting diode, corresponding to a previous data signal. The first driver stores a current data signal supplied from a data line and supplies the previous data signal to the second driver. In the pixel, the second driver includes a sixth transistor coupled between an initialization power source and a first node coupled to a gate electrode of a first transistor, the sixth transistor being configured to turn on when a first control signal is supplied; and a seventh transistor coupled between the first power source and a second node commonly coupled to the first and second drivers, the seventh transistor being configured to turn on when the first control signal is supplied. |

1. A pixel comprising:
an organic light emitting diode; a second driver configured to control an amount of current supplied from a first power source to the organic light emitting diode, corresponding to a previous data signal; and a first driver configured to store a current data signal supplied from a data line and to supply the previous data signal to the second driver, wherein the second driver comprises:
a sixth transistor coupled between an initialization power source and a first node coupled to a gate electrode of a first transistor, the sixth transistor being configured to turn on when a first control signal is supplied; anda seventh transistor coupled between the first power source and a second node commonly coupled to the first and second drivers, the seventh transistor being configured to turn on when the first control signal is supplied. |
