1. A display device, comprising:
a display panel including a first data line, a second data line, a first pixel in a first pixel row and connected to the first data line, a second pixel in the first pixel row and connected to the second data line, a third pixel in a second pixel row and connected to the first data line and a fourth pixel in the second pixel row and connected to the second data line, wherein the second pixel row is adjacent to the first pixel row; and
a display driver configured to receive image data including first, second, third and fourth pixel data for the first, second, third and fourth pixels, respectively, and to provide first, second, third and fourth data voltages respectively corresponding to the first, second, third and fourth pixel data to the first, second, third and fourth pixels through the first and second data lines, the display driver further configured to:
calculate average data of the first pixel data and the second pixel data; and
selectively perform a charge sharing operation between the first data line and the second data line according to whether a first increase/decrease condition among the first pixel data, the average data and the third pixel data and a second increase/decrease condition among the second pixel data, the average data and the fourth pixel data are satisfied,
wherein the first increase/decrease condition and the second increase/decrease condition are different from each other.
