Claim:
1. A 3D panel, comprising: a plurality of gate lines; a gate driving circuit, wherein in a 3D displaying, the gate driving circuit is configured to drive a first group of gate lines row by row in a scan of a (4k+1)-th frame for displaying a first image, where k is a natural number, to drive a second group of gate lines row by row in a scan of a (4k+2)-th frame for displaying a second image, to drive the first group of gate lines row by row in a scan of a (4k+3)-th frame for displaying a third image and to drive the second group of gate lines row by row in a scan of a (4k+4)-th frame for displaying a forth image; and a scanning direction controller, wherein the scanning direction controller is configured to control a scanning direction of the gate driving circuit, by keeping a scanning direction of the (4k+1)-th frame opposite to a scanning direction of the (4k+3)-th frame, and a scanning direction of the (4k+2)-th frame opposite to a scanning direction of the (4k+4)-th frame; wherein one of the first image and the second image is a left-eye image and the other is a right-eye image; wherein one of the third image and the fourth image is a left-eye image and the other is a right-eye image; wherein the first group of gate lines is in odd-numbered rows and the second group of gate lines is in even-numbered rows, or the first group of gate lines is in even-numbered rows and the second group of gate lines is in odd-numbered rows; wherein the scanning direction controller comprises a 2D/3D control end, a scanning direction control end and an output end, and the output end comprises a first output end and a second output end; wherein in a 2D displaying mode, the 2D/3D control end is connected to a 2D mode control signal, and wherein the output end controls the gate driving circuit to perform a forward scan or a reverse scan based on a scanning direction signal from the scanning direction control end; and wherein in a 3D displaying mode, the 2D/3D control end is connected to a 3D mode control signal, and the output end controls the gate driving circuit to sequentially perform a forward scan and a reverse scan based on a scanning direction signal from the scanning direction control end, wherein the forward scan and the reverse scan are respectively performed on corresponding frames.
