[0067] refer to Figure 1a and Figure 1b , Figure 1a and Figure 1b A first example of an optical structure is shown, including: a light-transmitting film 10 and a plurality of optical microstructures 11 disposed in the light-transmitting film 10 .
[0068] Wherein, the material of the light-transmitting film 10 may be various materials that allow light to pass through, and the light-transmitting film 10 may be transparent or translucent, and so on.
[0069] The front of each optical microstructure 11 forms a predetermined angle with the surface of the light-transmitting film 10 . There are intervals between adjacent optical microstructures 11 . The front side of the optical microstructure 11 scatters or reflects the incident light, that is, the light incident on the front side of the optical microstructure 11 will be scattered or reflected, while the light not incident on the front side of the optical microstructure 11 will directly pass through. The light-transmitting f...

[0087] refer to Figure 10 , Figure 10 A sixth example of a transparent display screen is shown, including: a light-transmitting film 90 , a plurality of optical microstructures 91 disposed in the light-transmitting film 90 , and a medium 92 bonded on one side of the light-transmitting film 00 . Figure 10 The sixth example shown with Figure 5 The structure of the transparent display screen in the first example shown is basically the same, the difference is that in the sixth example, one side surface of the medium 92 (the surface attached to the light-transmitting film 90 ) has a variety of film layers with different refractive indices in different regions. 921 , for example, has film layers 921 with refractive indices n4, n5 and n6 according to different regions. In addition, one surface of the medium 92 (the surface attached to the light-transmitting film 90 ) may also have an anti-reflection film or an anti-reflection film. The other surface of the medium 92 may also h...
