Abstract:
1. A display device comprising: a panel including a plurality of pixels connected to a plurality of data lines and a plurality of gate lines, each pixel comprising a switching device; a data driver that is connected to the plurality of data lines and configured to apply data signals having a first voltage level or a second voltage level which is lower than the first voltage level to the plurality of data lines; and a gate driver that is connected to the plurality of gate lines and configured to sequentially apply gate signals to the plurality of gate lines, the gate driver being configured to provide only one of a first gate-low voltage and a second gate-low voltage which is higher than the first gate-low voltage during an off period of each switching device, wherein the plurality of pixels comprise a first pixel and a second pixel that are connected to the same data line while the first pixel is connected to a first gate line and the second pixel is connected to a second gate line that is immediately next to the first gate line, the first pixel comprising a first switching device, the second pixel comprising a second switching device, wherein the gate driver is further configured to provide the first gate-low voltage to apply to the first pixel while providing the second gate-low voltage to apply to the second pixel in the same frame; wherein in a frame in which the data signal having the first voltage level is applied to the second pixel, in response to applying the first gate-low voltage to the second switching device, a pixel voltage of the first pixel is offset by a first constant value, and wherein in a frame in which the data signal having the second voltage level lower than the first voltage level is applied to the second pixel, in response to applying the second gate-low voltage higher than the first gate-low voltage to the second switching device, a pixel voltage of the first pixel is offset by a second constant value.
