Abstract: A pixel circuit includes a first switch element turned on by a gate-on voltage of a first scan pulse to apply a data voltage to a first node; a second switch element turned on by a gate-on voltage of a second scan pulse to connect a second node to a third node; a third switch element turned on by a gate-on voltage of a light-emitting control pulse to apply a reference voltage to the first node; a fourth switch element turned on by the gate-on voltage of the light-emitting control pulse to connect the third node to a fourth node; and a fifth switch element turned on by a gate-on voltage of the second scan pulse to apply the reference voltage to the fourth node. A voltage higher than or equal to the pixel driving voltage is applied to the third node before generation of the first scan pulse.

Abstract: Provided are a gate driving circuit and a display device including the same. The gate driving circuit includes a first outputter for outputting a first scan pulse that swings between a gate-on voltage and a first gate-off voltage, a second outputter for outputting a second scan pulse that swings between the gate-on voltage and a second gate-off voltage, and a controller for controlling the first and second outputters. The first gate-off voltage is set to be higher or lower than the second gate-off voltage.

Abstract: Disclosed is a method of driving a display device that includes, for example, generating a gate control signal, a data control signal and an image data using an image signal; generating a data voltage using the data control signal and the image data; generating a gate voltage using the gate control signal; and sequentially applying the gate voltage of a high level to q groups of the plurality of gate lines during q frames, respectively, where q is an integer greater than 1.

Abstract: A liquid crystal display (LCD) device are disclosed, which reduce power consumption and improve an image quality. The LCD device includes a liquid crystal panel in which a plurality of sub-pixels is defined by intersection of a plurality of gate lines and a plurality of data lines, and sub-pixels adjacent to each other in a column direction are connected by sharing the plurality of gate lines. A gate driver may sequentially transfer a scan pulse to even-numbered gate lines and then sequentially transferring a scan pulse to odd-numbered gate lines. A data driver may be synchronized with the applied scan pulse in providing data voltage to columns of sub-pixels. The data driver provides the data voltage having different polarities to a neighbor data line during one frame interval such that sub-pixels are driven by a horizontal 2-dot inversion scheme.
