Abstract
A stereoscopic display device and a display method thereof are provided. The stereoscopic display device includes a display panel, a lens array, an image sensor, and a processing circuit. The display panel displays a three-dimensional image. The lens array is disposed on a transmission path of the three-dimensional image. The image sensor acquires a sensed image of a viewing field of the display panel. The processing circuit is coupled to the lens array and the image sensor. The processing circuit calculates an actual eye position of a user in the viewing field according to reference coordinates of a reference position in the sensed image and eye coordinates of the user in the sensed image. The processing circuit adjusts a liquid crystal rotation angle of the lens array according to the actual eye position, so that a viewing position of the three-dimensional image matches the actual eye position.
