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.

Abstract: The present invention relates to systems for photoenergy up-conversion comprising polymers and sensitisers, where the triplet level of the polymer is lower than the triplet level of the sensitiser. These systems exhibit higher efficiency in up-conversion and are therefore more suitable for use in devices for up-conversion than polymers as used in accordance with the prior art.
