  • Pixel driving circuit and display panel
    Patent number: 11062658
    Abstract: A pixel driving circuit and a display panel are provided. The pixel driving circuit adopts a pixel driving circuit with a 4T1C structure to effectively compensate a threshold voltage of a driving transistor in each pixel. A compensation structure of the pixel driving circuit is simpler and easier to operate. By compensating the threshold voltage of the driving transistor through two compensation phases, it can achieve a wider compensation range of the threshold voltage, thereby improving brightness and a lifespan of the display panel.
