Patent ID: 8638324

Claim:
A display device comprising: a controller receiving an image data from an external device, outputting the image data in synchronization with a first timing signal, and outputting a second timing signal; a line inversion driving chip receiving the image data and inverting the image data to a first data voltage having a first polarity and a second data voltage having a second polarity different from the first polarity based on a positive gamma and a negative gamma alternately applied at every horizontal scanning period, where a horizontal scanning period is a 1H period, to alternately output the first data voltage and the second data voltage at a period that is equal to or less than the 1H period; a gate driving circuit outputting a gate signal during the 1H period in response to the second timing signal; and a display panel comprising: a plurality of gate lines sequentially receiving the gate signal; a plurality of data lines intersecting with the gate lines, insulated from the gate lines, and receiving the first and second data voltages at every 1H from the line inversion driving chip; and a plurality of pixels that receives the first and second data voltages in response to the gate signal and are arranged in a plurality of pixel rows to display an image, the plurality of pixels arranged in each of the plurality of pixel rows being divided into a first pixel group and a second pixel group receiving the first and second data voltages, respectively, the first and second pixel groups being alternately arranged in the each of the plurality of pixel rows, and a polarity of a data voltage applied to the first and second pixel groups being inverted at every pixel row, and wherein, the first pixel group is connected to corresponding data lines, the second pixel group is connected to corresponding data lines different from the data lines connected to the first pixel group.
