It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.

Fig. 1 is a schematic diagram of main blocks of a naked-eye 3D image display system according to an embodiment of the present invention.

As shown in fig. 1, a naked eye 3D image display system according to an embodiment of the present invention includes a display panel 101, a plurality of correction layers 102, and a plurality of prism layers 103; wherein:

a display panel 101 for displaying a flat image;

at least one correction layer 1021 of the plurality of correction layers 102 is disposed on the display panel 101; a correction layer 102 for filtering the light rays coincided during the display process;

each prism layer 103 is composed of a plurality of convex lenses; a prism layer 103 for refracting light by the convex lens;

the planar image is displayed as a 3D image by the filtering of the correction layer 102 and the refraction of the prism layer 103.

In the embodiment of the present invention, at least one correction layer is disposed on the display panel 101, and is configured to filter overlapping light rays of the light rays emitted by the display panel 101; the plurality of correction layers 102, except for at least one correction layer, are used for filtering the coincident light rays generated after refraction by the prism layer 103.

It is to be understood that the above mentioned marks of the correction layer 1021 and the correction layer 102 are only used for more clearly describing the embodiments of the present invention, the correction layer 1021 is an implementation manner corresponding to the correction layer in the naked-eye 3D image display system provided by the embodiments of the present invention, and the following marks of the correction layer 1022, the correction layer 1023, the correction layer 1024, and the correction layer 1025 are all similar to this, which are different implementation manners corresponding to the correction layer in the naked-eye 3D image display system provided by the embodiments of the present invention, that is, the correction layer 1022, the correction layer 1023, the correction layer 1024, and the correction layer 1025 are all the correction layer 102.

It is to be understood that the above-mentioned marks of the prism layer 1031 and the prism layer 103 are only made for the sake of more clearly describing the embodiments of the present invention, the prism layer 1031 is an implementation manner corresponding to the prism layer in the naked-eye 3D image display system provided by the embodiments of the present invention, and the following marks of the prism layer 1032, the prism layer 1033, and the like are all similar to these marks, and are different implementation manners corresponding to the prism layer in the naked-eye 3D image display system provided by the embodiments of the present invention, that is, the prism layer 1031, the prism layer 1032, and the prism layer 1033 are all prism layers 103.

In an embodiment of the present invention, the correction layer 102 is composed of any one of the following optical components: a privacy film, a plurality of light shields, or a plurality of polarizers.

In the embodiment of the present invention, the correction layer 102 uses the principle of a louver, as shown in fig. 2, the lowermost layer in fig. 2 represents the display panel 101, each quadrangle represents an optical component, each straight line represents light emitted from the display panel 101, and the dots represent the positions of human eyes. Among a plurality of light rays emitted from the lower side of the correction layer (the lower side of the correction layer 102 may be the display panel 101, or may be the prism layer 103), the optical component (correction layer) with a certain angle only allows light rays with certain angles to pass through, and light rays with other angles are overlapped with other light rays, so that the optical component (correction layer) with a certain angle blocks the light rays, as shown by the five light rays marked with crosses on the right side of fig. 2, the light rays cannot pass through the optical component (correction layer) to reach dots (human eyes), so that the correction layer 102 plays a role of filtering the overlapped light rays.

In a preferred embodiment of the present invention, the convex lenses constituting the same prism layer 103 have the same size and curvature.

The principle of the prism layer is shown in fig. 3, where the lowest layer in fig. 3 represents the display panel 101, each semicircle represents a convex lens, and each straight line represents the light emitted by the display panel 101 and refracted by the convex lens. The size and radian of the convex lens determine the refractive index of the convex lens, and the light emitted by the display panel 101 is refined and distributed through multiple layers of convex lenses with different refractive indexes, so that the light can be divided into more pixel areas (the pixel areas are small grids on the display panel 101 in fig. 3) in a limited area (the size of a screen is limited), and therefore, a user can see the light emitted from the pixel areas at different angles (eyes of each person in fig. 3), and the image seen by the user is more real.
