Abstract:
1. A stereoscopic image display device comprising: a display panel including data lines, scan lines, and a plurality of pixels formed in cell areas; an image converter that calculates disparity values based on depth values of the depth map extracting from 2D image data, calculates gain disparities by multiplying each of the disparity values by a predetermined gain value, generates left-eye image data and right-eye image data by shifting the 2D image data according to each of the gain disparities, and converts the left-eye image data and the right-eye image data into the 3D image data according to a 3D format; a data driver that converts the 3D image data to data voltage and supplies data voltage to the data lines; and a gate driver that sequentially supplies gate pulses synchronized with the data voltage to the gate lines, wherein the image converter comprises: a depth map extractor that extracts the depth map from the 2D image data; a disparity calculator that calculates the disparity values based on a convergence, a max disparity, and the depth values in the depth map; a gain disparity calculator that calculates the gain disparities by multiplying each of the disparity values by the predetermined gain value according to a horizontal position of each of the pixels; and a 2D image data converter that generates left-eye image data and right-eye image data by changing the horizontal position of the 2D image data according to each of the gain disparities, and wherein the predetermined gain value increases linearly from 0 to 1 in a first section where the horizontal position of the pixel is from 0 to a max disparity, maintains 1 in a second section where the horizontal position of the pixel is from the max disparity to a n-max disparity, decreases linearly from 1 to 0 in a third section where the horizontal position of the pixel is from the n-max disparity to n, and n is a natural number and the horizontal resolution of the display panel.
