Claim Text:
1. A stereoscopic image display device comprising: a display panel including a plurality of sub-pixels; an optical plate configured to control display of images in n numbers of sub-pixels in n numbers of viewpoints located at different positions, wherein n is an integer equal to or greater than 2; a 2D data converter configured to receive two-dimensional (2D) data for each of the n numbers of sub-pixels and to convert the 2D data for each of the n numbers of sub-pixels into different 2D data for each of the n numbers of sub-pixels, the different 2D data for each of the n numbers of sub-pixels being based on all of the 2D data for the n numbers of sub-pixels; a display panel driving circuit configured to receive the different 2D data for each of the n numbers of sub-pixels and to supply each of the different 2D data to a corresponding one of the n numbers of sub-pixels in a two-dimensional (2D) mode of the stereoscopic image display device, wherein the 2D data converter includes: a horizontal interpolation unit configured to calculate a kth horizontal interpolation data of a jth horizontal line by using a plurality of 2D data of the jth horizontal line, wherein j and k are each an integer greater than 0; and a vertical interpolation unit configured to calculate the kth vertical interpolation data of the jth horizontal line by using horizontal interpolation data of the jth horizontal line and adjacent lines to the jth horizontal line.
