Technical Field
The utility model relates to an integrated formation of image 3D shows, more specifically says, the utility model relates to an integrated formation of image double vision 3D display device based on pointolite.
Background
The principle of the double-view display is that two different pictures are displayed on one display screen at the same time, and viewers in different viewing directions can only see one picture, so that different requirements of a plurality of viewers are met on one display screen at the same time. In the existing dual-view display, two images are separated by a light splitting element such as a parallax barrier or a cylindrical lens, or a viewer wears different filters, so that an effect of displaying only one image in a certain viewing direction is achieved. However, the existing dual view display has a significant disadvantage: the display screen is a 2D screen, and three-dimensional display cannot be realized.

The display screen is used for displaying the micro-image array. The display screen is arranged in parallel right in front of the point light source array. The center of the point light source array is correspondingly aligned with the center of the display screen. The barrier array consists of a series of opaque barriers. The barrier array is located between the array of point light sources and the display screen. The point light source array is formed by arranging a plurality of point light sources with the same parameters at intervals. As shown in fig. 2, the micro-image array is composed of sub-image elements I in sub-micro-image array I and sub-image elements II in sub-micro-image array II, which are closely arranged. The size of the sub-picture element I in the sub-micro-picture array I is equal to the size of the sub-picture element II in the sub-micro-picture array II; the number of sub-picture elements I in the sub-micro-picture array I is equal to the number of sub-picture elements II in the sub-micro-picture array II. The image element consists of a subimage element I and a subimage element II; the pitch of the picture elements is equal to the pitch of the point light sources. The number of picture elements in the micro-image array is equal to the number of point light sources in the point light source array.
