    摘要： A pixel includes an organic light-emitting diode, a driving transistor, a first dual gate transistor, a first capacitor, and a compensation transistor. The organic light-emitting diode includes first and second terminals. The driving transistor generates the driving current and includes a first terminal to which a first power supply voltage is applied, a second terminal connected to the first terminal of the organic light-emitting diode, and a gate terminal. The first dual gate transistor is connected between the gate terminal of the driving transistor and the second terminal of the driving transistor and includes first and second sub-transistors. The first capacitor includes a first electrode to which the first power supply voltage is applied, and a second electrode connected to a first node that connects the first and second sub-transistors to each other. The compensation transistor includes a terminal connected between the second electrode and the first node.

    摘要： A display panel, a display driving method and a display pixel driving circuit therefor are provided. In the display driving method, the light emitting signal includes multiple pulse signals, and the variation trend of the pulse-off durations of the pulse signals is consistent with the variation trend of the light emitting brightness of the light emitting element during the light emitting period, that is, the pulse-off durations decreases sequentially with the decrease of the light emitting brightness of the light emitting element, or sequentially increases with the increase of the light emitting brightness of the light emitting element. Therefore, the flicker problem in the display panel when emitting light can be solved, and improving the image display quality.
