Abstract
An exemplary active matrix display device includes a display panel comprising a plurality of scanning lines extending along a horizontal axis, a plurality of data lines extending along a vertical axis, and a plurality of dummy data lines. Two scanning lines and two data lines define two display pixels; each of the plurality of data lines is connected to at least two adjacent display pixels along the horizontal axis, and the at least two adjacent display pixels are driven by the two scanning lines, respectively. Each of the plurality of dummy data lines is disposed between two random adjacent data lines and is provided with gray scale voltage signals by a driving circuit of the display panel, thereby forming coupling capacitances between each of the plurality of dummy data lines and two pixel electrodes of the two display pixels.
