Patent number: 9508182Abstract: A display apparatus includes a display panel and an active parallax barrier panel. The display panel displays n numbers of viewpoint images on a display panel (‘n’ is natural numbers greater than 2). The active parallax barrier panel includes a plurality of barrier units. Each of the barrier units includes an opening portion and a blocking area divided into m numbers of sub-areas. The active parallax barrier panel selectively opens the m numbers of sub-areas to exit the m numbers of viewpoint images on (n×m) numbers of viewpoint positions (‘m’ is natural numbers greater than 2). Thus, an active parallax barrier panel is time-division driven to display multi-viewpoint images. Moreover, a pixel structure and a barrier structure are alerted, so that deterioration of a resolution of a 3D image may be minimized.Type: GrantFiled: December 4, 2012Date of Patent: November 29, 2016Assignee: SAMSUNG DISPLAY CO., LTD.Inventor: Goro Hamagishi
