  • Patent number: 10049634
    Abstract: The disclosure provides a pixel circuit and a driving method thereof, a driving circuit, and a display device, which pertains to the field of pixel driving technology. The pixel circuit includes a capacitor, a capacitor charging transistor, a first and second capacitor discharging transistor. The capacitor is charged to a first voltage greater than the pixel voltage when the capacitor charging transistor is turned on. The capacitor is connected in series with the first and second capacitor discharging transistor to form a discharge circuit, and the capacitor is discharged when the first and second capacitor discharging transistor are turned on so that the voltage across the capacitor drops from the first voltage to the pixel voltage. There is no need to arrange a Gamma resistor for the driving circuit for the pixel circuit array provided by the disclosure, which makes the structure simple and the power consumption in driving low.
