OLED Display Device |
| 摘要 |
An OLED display device includes an OLED display panel on which subpixels are disposed, a gamma reference voltage supply circuit supplying gamma reference voltages that are variable during driving and when sensing a threshold voltage, and a data driver supplying data voltages based on the gamma reference voltages to data lines. The data driver senses a voltage of a sensing node within each of the subpixels in sensing mode. A timing controller controls the data driver, and performs a compensation process based on the voltage sensed by the data driver. |
