  • 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.

  • Patent number: 10222546
    Abstract: There are provided green-emitting quantum dots (QDs) including I-III-VI type ternary Cu—Ga—S core QDs and ZnS multishell wherein Cu:Ga is 1:10 to 1:1, and a fabricating method thereof. Integration of these QDs and red-emitting QDs into a blue LED leads to the fabrication of a white light-emitting device with high color rendering index. There are also provided blue-emitting QDs including I-III-VI type quaternary Zn—Cu—Ga—S or Cu—Ga—Al—S core QDs and ZnS multishell, and a fabricating method thereof. An electrically-driven blue light-emitting device with a QD emitting layer including these QDs interposed between a hole transport layer and an electron transport layer is fabricated.
