Stereoscopic image display device and method for driving the same

A stereoscopic image display device comprising:

• a display panel comprising data lines, gate lines, and a plurality of pixels;
• a data modulation unit that outputs modulated 3D image data by modulating kth pixel data of a jth line based on the kth pixel data of the jth line and kth pixel data of a line adjacent to the jth line,
• wherein k is an integer less than or equal to n and greater than 1, and n is a horizontal resolution of the display panel,
• wherein j is an integer less than or equal to m and greater than 2, and m is a vertical resolution of the display panel;
• a data driving circuit that converts the modulated 3D image data into analog data voltages and outputs the analog data voltages to the data lines;
• and
• a gate driving circuit that sequentially outputs gate pulses to the gate lines.
