  • Pixel driving circuit, display panel, and driving method of pixel driving circuit
    Patent number: 12154509
    Abstract: A pixel driving circuit, a display panel and a driving method of the pixel driving circuit are provided by the present disclosure. The pixel driving circuit includes a driving transistor, a reset module, a writing module, a first control module, and a light emitting device. The pixel driving circuit with the 5T2C structure can compensate the threshold voltage drift of the driving transistor, improve the luminous uniformity of the light emitting device, and further improve the image quality.
    Type: Grant
