In the human eye 30 of the central axis, that is, the two pixels located at the two side edges 11 of the triangular prism 10 are superimposed on the image 40 formed in the human eye.

The light-transmitting structure of the transparent film provided by the present invention is as shown in FIG. 2-3, and the transparent film 50 includes two faces, one face is a smooth plane 51, and the other face 52 is evenly distributed with a plurality of tiny pieces of the same size. The triangular prism-shaped projections 521 are all on the same plane 52, and the central axes 5211 of all the projections 521 which are parallel to both sides of the projections are parallel to each other. In this embodiment, the central connections of all the projections form a mesh, and each of the grids is a square of the same size. The length of the bottom side of each of the triangular prism-shaped protrusions is between 0.05 mm and 0.5 mm, and adjacent prisms The distance between the adjacent sides of the bottom surface of the convex shape shall not exceed 2 times of the length of the bottom side of the triangular prism-shaped protrusion, that is, the distance between the adjacent sides of the bottom surface of the adjacent triangular prism-shaped protrusion is 0 mm to 1 mm. . Preferably, in this embodiment, the distance between adjacent sides of the bottom surface of the adjacent triangular prism-shaped protrusions, and the length of the bottom side of each of the triangular prism-shaped protrusions is 0.1 mm. Therefore, in practice, the distance between the adjacent triangular prism-shaped protrusions and the size between the protrusions are similar to the size of the pixel points of the display, so that the light-transmissive film is disposed in front of the two images, and the A straight line connecting the center of the image and the second image is perpendicular to the central axis of the protrusion on the light-transmissive film, and the convex surface of the light-transmissive film is opposite to the first image and the second image to realize an image. Superposition.
