PIXEL CIRCUIT AND ORGANIC LIGHT EMITTING DISPLAY DEVICE INCLUDING THE SAME |
| 摘要 |
A pixel circuit and organic light emitting display device using the pixel circuit are disclosed. One aspect of the pixel circuit includes an organic light emitting diode, a switching transistor configured to transfer a data signal in response to a scan signal, a storage capacitor configured to store the data signal transferred through the switching transistor, an amplifying unit configured to amplify the data signal stored in the storage capacitor to generate an amplified signal having a swing range greater than a swing range of the data signal, and a driving transistor configured to drive the organic light emitting diode in response to the amplified signal. |

1. A pixel circuit, comprising:
an organic light emitting diode; a switching transistor configured to transfer a data signal in response to a scan signal; a storage capacitor configured to store the data signal transferred through the switching transistor; an amplifying unit configured to amplify the data signal stored in the storage capacitor so as to generate an amplified signal having a swing range greater than a swing range of the data signal; and a driving transistor configured to drive the organic light emitting diode in response to the amplified signal.
