摘要： The present application provides a pixel and a control method thereof and a related OLED display. The present application could utilize the driving TFT having a main gate and a sub-gate and utilize the internal compensation to store the threshold voltage of the driving TFT into the second storage capacitor. In addition, the data voltage is applied to the first storage capacitor. The driving TFT is controlled by the main gate and the sub-gate to drive the light emitting unit to generate light. Because the threshold voltage of the second storage capacitor is applied to the driving TFT, the current flowing to the driving TFT and the threshold voltage are unrelated.
