[0047] Example 1
[0048] The embodiment of the present invention provides a grating film, such as figure 1 As shown, the grating film 500 includes a first substrate 100, a first microstructure 150, a second microstructure 200, and a second substrate 300 arranged in sequence;
[0049] The first microstructure 150 is disposed on the surface of the first substrate 100, and the second microstructure 200 is disposed on the surface of the second substrate 300; the shape of the first microstructure 150 is complementary to the shape of the second microstructure 200, and the first microstructure 150 It is anastomosedly connected with the second microstructure 200.
[0050] In the embodiment of the present invention, the grating film 500 includes a first substrate 100 and a second substrate 300 disposed opposite to each other. The materials of the first substrate 100 and the second substrate 300 are both flexible and high-transmittance materials, such as PET (polyethylene glycolterephthalate, p
Example Embodiment
[0060] Example 2
[0061] The embodiment of the present invention provides a stereoscopic display device, such as Figure 5 As shown, the stereoscopic display device 1000 includes a 2D liquid crystal display module 450 and the grating film 500 provided in the first embodiment;
[0062] The first substrate 100 of the grating film 500 and the side of the 2D liquid crystal display module 450 close to the user are bonded together by the adhesive 400; the extension direction of the first microstructure 150 and the second microstructure 200 of the grating film 500 is consistent with The extension direction of the sub-pixels of the same color in the 2D liquid crystal display module 450 is vertical.
[0063] Figure 5 A cross-sectional view of the stereoscopic display device 1000 is shown. Among them, in the 2D liquid crystal display module 450, in the direction perpendicular to the cross-sectional view, each column of sub-pixels has three sub-pixels: R (Red), G (Green), and B (Blue, blue) Th
