  • Pixel driving circuit and driving method thereof, and display apparatus
    Patent number: 12763017
    Abstract: Disclosed are a pixel driving circuit and a driving method thereof, and a display apparatus, the circuit includes a driving transistor; a storage capacitor; an initializing unit configured to transmit an initialization voltage to a second node to charge the storage capacitor; a threshold compensation unit configured to obtain a threshold voltage of the driving transistor in response to a first scanning signal scanned at a first frequency and update a potential of the second node; a data writing unit configured to transmit a data signal to a first node; a reset unit configured to reset a potential of the first node in response to a second scanning signal scanned at a second frequency; a light emitting control unit configured to control light emission of an organic light emitting diode; the second frequency being N times the first frequency, N being an integer greater than or equal to 1.
