Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel comprising a plurality of gate lines (GL a timing controller arranging the external input image data to be proper to the driving of the liquid crystal panel, generating a gate control signal (GCS) and a data control signal (DCS), and grouping the arranged image data into a plurality of groups each having a plurality of controller channels, and outputting a group control signal (HINV_m) by determining whether each group of the arranged image data is proper to horizontal-1-dot inversion or horizontal-2-dot inversion; a gate driver driving the plurality of the gate lines of the liquid crystal panel based on the gate control signal (GCS) from the timing controller; and a data driver grouping output terminals thereof into a plurality of groups, the number of the groups grouped by the data driver corresponding to the number of the groups grouped by the timing controller, selecting positive or negative gamma voltages corresponding to the arranged image data for each group based on the group control signal from the timing controller, and converting the arranged image data into an analog image signals by using the selected gamma voltage, wherein the timing controller comprises: an image processing unit arranging an external image data (RGB) to be proper to the driving of the liquid crystal panel, and generating the gate control signal (GDS) and the data control signal (DCS) by using an external input synchronization, a group control unit grouping the arranged image data from the image processing unit into a plurality of groups each having a plurality of controller channels, determining whether every group of arranged image data is proper to the horizontal-1-dot inversion or the horizontal-2-dot inversion, and outputting a group control signal (HINV_m) according to the result of the determining, and a low voltage differential signaling (LVDS) output unit outputting the arranged image signal, the data control signal (DCS) from the image processing unit, and the group control signal (HINV_m) from the group control unit to the data driver.
