  • DISPLAY PANEL AND DISPLAY DEVICE
    Publication number: 20250095586
    Abstract: A display panel and a display device are disclosed. By setting numbers of effective pulses of first start signals in both a writing frame and a holding frame of one display period to be plural, a plurality of first strobe driving circuits connected in cascade are allowed to output a plurality of first strobe signals multiple times to adjust a bias voltage of a first transistor of a plurality of pixel driving circuits. Therefore, the display panel can display at a similar light-emitting brightness in both the writing frame and the holding frame, thereby improving a flickering problem of the display panel.
    Type: Application
