  • Patent number: 10629125
    Abstract: A display device includes a substrate including an active area having a plurality of pixels and a bezel area around the active area; a data driver on one side of the bezel area; a gate driver on at least one side of the bezel area; a shield power supply line extending from the data driver to at least one side of the gate driver; and a shield layer overlapped with at least one thin film transistor of the gate driver and connected to the shield power supply line in the bezel area.
    Type: Grant

  • Patent number: 10522609
    Abstract: A gate driver circuit, a display device, and a method of driving the display device are disclosed. The gate driver circuit includes a first transistor supplying a start signal to a Q node in response to a clock, a second transistor adjusting a gate voltage of the first transistor in response to the clock, a third transistor adjusting a gate voltage of the second transistor in response to the start signal, a fourth transistor changing a voltage of a QB node, a fifth transistor switching a current path between the first transistor and the Q node in response to a first line control signal, a sixth transistor supplying a gate-off voltage to an output node, a seventh transistor supplying a gate-on voltage to the output node, and an eighth transistor supplying a second line control signal to the QB node.
