  • Patent number: 10645373
    Abstract: A 3-dimensional displaying apparatus includes an image displaying panel having a plurality of pixels and a backlight panel spaced apart from one surface of the image displaying panel. The backlight panel includes a first line source set having a plurality of line sources arranged at regular intervals and a second line source set having line sources arranged spaced apart from the respective line sources of the first line source set by a predetermined interval. The first line source set and the second line source set are driven alternately. Thus, in a case where a horizontal location of an observer varies, the change of brightness of image information and the crosstalk between adjacent visual fields are minimized, and pseudo-stereoscopic vision is prevented. Also, the irregularity of brightness distribution in a visual field may be solved.
