Problems solved by technology

[0002] At present, the existing display devices on the market can only focus on one point. When making a video, the photographer either focuses on the near view or the distant view. When focusing on the near view, the near view is clear and the distant view is blurred. On the contrary, When focusing on the distant view, the distant view is clear, and the close view is blurred. Therefore, when the audience is watching, the focus of viewing is the scene that the photographer has already arranged. , to express related ideas, but this is relatively depriving the viewer of the right to independently choose what to watch. For example, some viewers prefer to appreciate the scenery in the distant view, but the photographer focuses on the close-up characters, so there is a certain contradiction

Abstract

The invention relates to a multi-focus three-dimensional display device which comprises a support body, at least two imaging display screens, at least one reverse image reflecting mirror and at least one combination imaging lens. The support body is divided into at least two layers. The imaging display screens are respectively placed on the two layers of the support body. The imaging display screens are arranged in a mutually parallel mode. The reverse image reflecting mirror or the combination imaging lens is arranged in front of one imaging display screen. The included angle between the reverse image reflecting mirror and one imaging display screen is alpha. The included angle between the combination imaging lens and one imaging display screen is beta. The combination imaging lens is arranged over one reverse image reflecting mirror. The obverse side of the combination imaging lens faces towards the imaging display screens. The reverse side of the combination imaging lens faces towards observers. The multi-focus three-dimensional display device is simple in structure and good in three-dimensional sense.
