Patent ID: 8368625

Claim:
An active matrix display device, comprising: a display panel comprising a plurality of scanning lines extending along a horizontal axis of the display panel, a plurality of data lines extending along a vertical axis of the display panel, and two scanning lines and two data lines defining two display pixels; a plurality of dummy data lines, wherein each of the plurality of dummy data lines is disposed between two adjacent display pixels located between the two random adjacent data lines; and a data driving circuit, configured for driving the plurality of data lines, wherein the plurality of dummy data lines comprise at least a common connective end electrically connected to the data driving circuit, the data driving circuit provides gray scale voltages for the plurality of dummy data lines; wherein each of the plurality of data lines is connected to at least two adjacent display pixels along the horizontal axis, the at least two adjacent display pixels are driven by two corresponding scanning lines respectively, and 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, to form coupling capacitances between each of the plurality of dummy data lines and two pixel electrodes of the two display pixels, wherein the polarity of the gray scale voltage for the two random adjacent data lines is opposite to the polarity of the gray scale voltage for the corresponding dummy data line at the same time.
