  • Patent number: 10424252
    Abstract: A display panel includes a substrate including a first area and a second area, a gate driver configured to supply a gate signal to pixels disposed on the substrate, a plurality of stages constituting the gate driver, and a first clock signal line and a second clock signal line to be respectively applied with a first clock signal and a second clock signal having the same phase. The plurality of stages are connected to the first area and the second area and driven at the same time. The first clock signal line and the second clock signal line are connected to each of the plurality of stages connected to the first area and the second area.

  • Patent number: 8520076
    Abstract: A liquid crystal display is capable of detecting a failure of a gate driver, and a method of testing the same are provided. The liquid crystal display includes a liquid crystal display panel on which liquid crystal cells connected to thin film transistors (TFTs) located at crossings between gate lines and data lines are formed, a data driver that drives the data lines of the liquid crystal display panel, and a gate driver which includes first to nth stages (n is a natural number larger than 1) formed on the liquid crystal display panel that generates normal scan signals for turning on the TFTs in a normal mode, and that generates test scan signals for turning off the TFTs in a test mode.
