  • Gate driver and display device including the same
    Patent number: 10643546
    Abstract: A gate driver and a display device including the same are disclosed. The gate driver includes a plurality of stages. Each stage includes a transistor T6 outputting an emission signal of a gate-on voltage to a node Na while a node Q is activated, a transistor T7 outputting the emission signal of a gate-off voltage to the node Na while a node QB is activated, a Q controller controlling a voltage of the node Q depending on a clock signal ECLK1 and a clock signal ECLK2 that are in antiphase, and a voltage of a node Q?, a QB controller controlling a voltage of the node QB depending on the clock signal ECLK1, the voltage of the node Q, and the voltage of the node Q?, and a capacitor CQ connected between an input terminal of the clock signal ECLK1 and the node Q.
    Type: Grant
