Abstract

An electronic device and a 3D image display method are disclosed. A receiver receives 3D video data including left-view video data and right-view video data. A formatter generates a first video frame and a second video frame, wherein the first video frame includes first pixel data of one of the left-view video frame and the right-view video frame in odd lines and includes second pixel data of the other of the left-view video frame and the right-view video frame in even lines, and wherein the second video frame includes third pixel data of one of the left-view video frame and the right-view video frame in odd lines and includes fourth pixel data of the other of the left-view video frame and the right-view video frame in even lines. A display scans the first video frame and the second video frame.
