And the larger the suitable viewing distance of the 3D display with the larger size is, the larger the suitable stereoscopic imaging focal distance is.
However, the conventional naked-eye 3D display technology relates to a single layer of grating, and generally requires 9-16 or more view-point pictures and the conventional display method can reduce the resolution of a single picture to 1/9 or 1/16 of the resolution of the display panel, so as to satisfy the 3D display with a wide viewing angle, which cannot satisfy the current demands of people.
In summary, the present invention solves the existing problems by designing a 3D display with a double-layer lenticular lens.
Disclosure of Invention
The present invention is directed to a 3D display with a double-layer lenticular lens to solve the above-mentioned problems.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a double-deck lens grating's 3D display, includes the display body, the back of display body has display body support frame through the screw connection, the display body is by supreme display frame, the board that is shaded, display panel, polaroid, lower glass, liquid crystal, last glass, first lens grating and the second lens grating of mainly including down, board, display panel, polaroid, lower glass, liquid crystal, last glass, first lens grating and the second lens grating of being shaded are installed in the inside of display frame from lower to upper.
Preferably, the focal length and the width of the first lenticular lens grating are both smaller than those of the second lenticular lens grating.
Compared with the prior art, the invention has the beneficial effects that:
1. in the invention, by designing that the focal length and the width of the first lens grating are both smaller than those of the second lens grating, the width of the first lens grating is smaller, the first lens grating is used for focusing one pixel light source into a plurality of smaller line light sources, the width of the second layer of lens grating is larger, the effect is similar to that of the lens grating used by a common naked eye 3D display, so that different positions of different ten-point picture focusing are separated, and thus when the multi-viewpoint naked eye 3D display is designed, excessive resolution does not need to be lost like the prior art.
2. In the invention, two layers of lenticulations are designed, so that the problems that the existing naked eye 3D display technology relates to a single layer of lenticulations, and in order to meet the 3D display of a wide viewing angle, 9-16 or more viewpoint pictures are generally needed, and the resolution of a single picture is correspondingly reduced to 1/9 or 1/16 of the resolution of a display panel by the existing display method are solved, and the requirements of people at present can be further met, so that the invention has stronger practicability and is more suitable for large-scale popularization and use.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution:
A3D display of double-layer lens grating comprises a display body 1, the back of the display body 1 is connected with a display body supporting frame 2 through screws, the display body 1 mainly comprises a display frame 3, a backlight plate 4, a display panel 5, a polarizer 6, a lower glass 7, a liquid crystal 8, an upper glass 9, a first lens grating 10 and a second lens grating 11 from bottom to top, the backlight plate 4, the display panel 5, the polarizer 6, the lower glass 7, the liquid crystal 8, the upper glass 9, the first lens grating 10 and the second lens grating 11 are arranged in the display frame 3 from bottom to top, the focal length and the width of the first lens grating 10 are both smaller than those of the second lens grating 11, the first lens grating 10 acts on focusing a pixel light source into a plurality of smaller linear light sources, the second lens grating 11 acts on being similar to the lens grating used by a common naked eye 3D display, to separate different positions of the picture focus of different ten points
Example 1
As shown in fig. 2, the display body 1 mainly includes, from bottom to top, a display frame 3, a backlight plate 4, a display panel 5, a polarizer 6, a lower glass 7, a liquid crystal 8, an upper glass 9, a first lenticular lens 10 and a second lenticular lens 11, and is installed inside the display frame 3 from bottom to top, the focal length and the width of the first lenticular lens 10 are both smaller than those of the second lenticular lens 11, the first lenticular lens 10 functions to focus one pixel light source into a plurality of smaller line light sources, and the second lenticular lens 11 functions to separate different positions of picture focusing at different ten points, similar to the lenticular lens used in a general naked-eye 3D display, so that the two lenticular lenses have different focal lengths and widths.
Therefore, through implementation in the scheme, as shown in fig. 4, when the multi-view 3D display is used, only 2 view pictures need to be displayed, each view picture forms a plurality of linear light sources after passing through the first lenticular lens 10, which means that one left picture and one right picture are changed into a plurality of parallel left pictures and parallel right pictures, and the pictures are focused by the second lenticular lens to different positions, so that the display with 2 views can achieve the effect of multi-view naked-eye 3D display, and the resolution is reduced from 1/9 or 1/6 in the prior art to 1/2, thereby solving the problem that the resolution of a single picture is reduced to 1/9 or 1/16 of the resolution of a display panel by using the existing naked-eye 3D display technology, which relates to a single-layer lenticular lens, and in order to satisfy the 3D display with a wide viewing angle, and then can satisfy people's demand now, therefore the practicality is stronger, more is fit for using widely on a large scale.
