Abstract: A stereoscopic image display device includes a display panel configured to display an image and an optical member that refracts image display light emitted in the display area of the display panel, outputting it as stereoscopic image display light. A plurality of image sensors arranged in the display area capture front-side image data. A main driver circuit analyzes the front-side image data to track a user's location and/or the user's right and left eye positions and controls pixels in the display area to display right-eye and left-eye image data. The main driver circuit further adjusts the viewing points of the right-eye and left-eye image data based on the tracked user's location and/or eye positions and drives the pixels to display a stereoscopic image aligned with the adjusted viewing points.
