Abstract
A display device is disclosed. Plural sub-pixels of a display panel are connected to two adjacent gate lines. Each data line is connected to two adjacent sub-pixels of same pixel. In first or second pixel sets, the first and the fourth gate lines are connected to sub-pixels in same column. The second and the third gate lines are connected to sub-pixels in same column. The sub-pixels connected to the fourth gate line of the first pixel set and the first gate line of the second pixel set are located in different columns. In one frame time, the data signal drives same pixel through the nth and (n+1)th data lines using opposite polarities and the data signal drives two adjacent sub-pixels of same pixel set in column direction through the nth and (n+1)th data lines using the same polarities.
