  • Display panel and electronic device
    Patent number: 11462147
    Abstract: A display panel and an electronic device is provided. A voltage drop value of the clock input transistor of a pull-up module of m1st GOA unit connected to an n1st clock signal line is greater than a voltage drop value of the clock input transistor of a pull-up module of m2nd GOA unit connected to the n2nd clock signal line. Based on this circuit structure, a CK impedance difference existing in 8K ultra-high resolution electronic devices can be alleviated.
