Description
Technical Field
The utility model relates to a 3D shows, more specifically says, the utility model relates to a 3D display device based on slit grating and post lens grating.
Background
The one-dimensional integrated imaging 3D display technology is a true 3D display technology without any vision-aid equipment. The technology has the characteristic of being watched by naked eyes, the recording and displaying processes are relatively simple, and full true color stereo images can be displayed, so that the technology is one of hot spot technologies of 3D display at present. However, the bottleneck problem of insufficient 3D resolution seriously affects the experience of viewers, thereby restricting the wide application of one-dimensional integrated imaging 3D display. While reducing the lenticular and image element pitch may increase resolution, the viewing angle may be reduced.
Disclosure of Invention
The utility model provides a 3D display device based on slit grating and cylindrical lens grating, as shown in figure 1, which is characterized in that the device comprises a display screen, a slit grating and a cylindrical lens grating; the slit grating and the cylindrical lenticulation are arranged in parallel in front of the display screen and are correspondingly aligned; the slit grating is attached to the cylindrical lens grating; the display screen is used for displaying the micro-image array; the pitch of the slits is equal to the pitch of the picture elements; the number of slits equals the number of picture elements; the pitch of the image element is a multiple of the pitch of the cylindrical lens, and the aperture width of the slit is a multiple of the pitch of the cylindrical lens; the centers of the slits are correspondingly aligned with the centers of the corresponding image elements; the display screen is positioned on the focal plane of the cylindrical lenticulation; and reconstructing a plurality of 3D images by each image element through a plurality of corresponding cylindrical lenses, and combining the 3D images into a high-resolution 3D image in a viewing area.
RPreferably, the resolution R of the one-dimensional integrated imaging 3D display is
（1）
p w mWhere p is the pitch of the cylindrical lenses, w is the aperture width of the slit, and m is the number of picture elements.
