Abstract:
1. A display device comprising: a display panel including a plurality of gate lines, a plurality of data lines and a plurality of pixels connected to the plurality of gate lines and the plurality of data lines; a gate driver supplying a gate signal to the plurality of gate lines; a data driver supplying a data signal to the plurality data lines; and a signal controller controlling the gate signal and the data signal, wherein the signal controller includes a data converter converting a gray value of image data when a difference in a gray value of the image data of two adjacent pixels of the plurality of pixels connected to a same data line of the plurality of data lines is greater than or equal to a first threshold value, wherein: the data converter includes: a data comparator counting a number of cases where the difference in the gray value of the image data of the two adjacent pixels connected to the same data line is greater than or equal to the first threshold value and determining whether the number of cases is greater than or equal to a second threshold value; and a gray value corrector converting the gray value of the image data when the number of cases is greater than or equal to the second threshold value, and the data comparator: counts, when the plurality of pixels is disposed in a zigzag with respect to the plurality of data lines, and counts the number of cases where the difference is greater than or equal to the first threshold value by comparing the differences in the gray values of the image data of two pixels of the plurality of pixels that are adjacent in a diagonal direction.
