Abstract:
1. A stereoscopic image display device, comprising: a liquid crystal display panel on which frame data is addressed in order of a (n+1)-th frame data to a (n+4)-th frame data, n being a positive integer; a frame rate conversion unit that divides 3D input data into left eye image data and right eye image data, and inserts reset frame data including black grayscale data between the left eye image data and the right eye image data, thereby generating the (n+1)-th frame data including the left eye image data, the (n+2)-th frame data including the black grayscale data, the (n+3)-th frame data including the right eye image data, and the (n+4)-th frame data including the black grayscale data; a shutter control signal transmitter that outputs a shutter control signal to shutter glasses, the shutter control signal controlling: a backlight unit that provides light to the liquid crystal display panel by periodically repeating turning on and off, the backlight unit being turned on: a luminance difference compensation unit that generates compensation values for compensating a luminance difference depending on positions in a screen of the liquid crystal display panel according to a turning-on timing of the backlight unit, wherein a compensation value added to the left eye image data and the right eye image data to be displayed on an upper part of the screen of the liquid crystal display panel is higher than a compensation value added to the left eye image data and the right eye image data to be displayed under the upper part of the screen of the liquid crystal display panel.
