Abstract: A liquid crystal display device and a driving method of the liquid crystal display device includes a display panel including a plurality of gate lines, a plurality of data lines crossing the gate lines, and a plurality of pixels coupled to the gate lines and the data lines, a gate driver configured to provide a gate signal to the pixels through the gate lines, a data driver configured to provide a data signal to the pixels through the data lines and a timing controller configured to receive an image data provided from an external device and generate control signals that control the gate driver and the data driver. The timing controller analyzes a pattern of the image data by every frame, and changes an inversion driving method and gamma voltages of the image data based on a pattern analyzing result from the analysis of the pattern of the image data.

Abstract: A stage of a gate driving circuit includes: a first control transistor diode-connected between a first input end of the stage and a first node, biased by a first input signal, and back-biased by a second input signal; a second control transistor including a control end which receives a third input signal, a first end connected to the first node, and a second end connected to a first voltage, and back-biased by a fourth input signal; a first output transistor including a control end connected to the first node, a first end connected to a clock input end of the stage, and a second end connected to a first output end of the stage; and a capacitor connected between the control and second ends of the first output transistor. The second input signal and the fourth input signal have enable levels during different periods.
