ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE |
| 摘要 |
Provided is an OLED display device that is in a black mode in which a threshold voltage of a driving TFT need not accurately be sensed. Further, a low voltage value of zero or less is constantly and continuously supplied to a data line during an initialization period, a sampling period, and a programming period in a pixel. As a result, when the pixel is driven in the black mode, a reference voltage and a data voltage having different values are not alternately supplied to the data line to minimize power consumption. |

1. A display panel comprising:
a gate driver; a gate line extending from the gate driver; a data line applying a data voltage to a pixel which corresponds to a point where the gate line and the data line cross each other, the pixel including an internal compensation pixel driving circuit, wherein while the pixel implements a black color, only one voltage value is present, and wherein the voltage value is applied to the pixel from the data line. |
