  • Patent number: 11924399
    Abstract: A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.
