Embodiment 1

[0075] Embodiment 1, according to a structural scheme 2 of a 3D projection film,

[0076] On the upper surface of the square film 1, there are several triangular prisms 2 that are closely arranged in parallel, neatly arranged in parallel, bounded by the vertical midline of the film 1 and parallel to the vertical side of the film 1 or the vertical side of the display. , the cross-section of the triangular prism 2 is a triangle, there are respectively unequal angles such as 30 degree angle and 60 degree angle between the two sides and the base of the triangle of the cross-section of the triangular prism 2 and the base of the triangle On the upper surface of the film 1, the width of the base of the triangle in the cross-section is 1500 μm or several values, and the triangles in the cross-section of the triangular prism 2 on both sides of the median line are bounded by the median line Or symmetrically arranged, the cross-sections of all the triangular prisms 2 are similar and / or e...

Embodiment 2

[0079] Embodiment 2, according to a structural scheme 3 of a 3D projection film,

[0080] On the upper surface of the square film 1, engrave or make a number of closely arranged rectangular pyramids 7 whose bottom diagonal lines are parallel to the corresponding sides of the film 1 or the corresponding sides of the display. The corresponding slopes of the adjacent quadrangular pyramids 7 are in the same direction, and the adjacent two rows of quadrangular pyramids 7 are closely spaced and neatly arranged. There is an angle between each slope of the quadrangular pyramids 7 and the bottom surface, such as a 45 ° angle, The angles between the opposite slopes and the bottom surfaces are equal, the angles between the adjacent slopes and the bottom surfaces are equal, the bottom surfaces of all the quadrangular pyramids 7 are similar and / or the area is equal, the height is equal, and the base width of the quadrangular pyramids 7 At 1500 μm or several values, the bottom surface of th...

Embodiment 3

[0082]Embodiment 3, according to a structural scheme 6 of a 3D projection film, on the upper surface of the square film 1, there are several closely arranged bottom edges or a corresponding edge of the film 1 or the bottom edge of the display. A parallel triangular pyramid 9 corresponding to the side, wherein the corresponding slopes of the triangular pyramids 9 separated in the same row are in the same direction, and the corresponding slopes of the adjacent triangular pyramids 9 in the same row are arranged in a positive and negative direction, and the triangular pyramids There is an angle between each slope of 9 and the bottom surface, and the angle between the corresponding slope and the bottom surface is equal, such as 45 degrees or 35 degrees. The bottom surface of the triangular pyramid 9 is on the upper surface of the film 1, and all of the The heights of the triangular pyramids 9 are equal and the bottom surfaces are similar and / or the areas are equal. The bottom surfac...

Abstract

The invention relates to a 3D projection film and / or method of use, belongs to the optical field and particularly relates to the technology of 3D display. The shortages in previous display technology are solved. The key points of the technical scheme are that an upper surface of a film has a plurality of triangular prisms which are closely and neatly arranged and are parallel to a vertical side of the film or a vertical side of a display device, the cross sections of the triangular prisms are isosceles triangles, the bottom sides of the isosceles triangles are at the upper surface of the film, two slopes of all triangular prisms have protection layers, the lowest layer of the film has a highly transparent adhesive layer or adhering layer, the adhesive layer is stuck to the surface of the display device, after a 3D film source of an image or video in the display device is reflected or refracted by the film of the invention, an image or video viewed by naked eyes of people has a 3D effect, and the 3D projection film is mainly used for the holographic naked eye 3D projection display for some kinds of display devices and some kinds of TV monitors and projectors.

Description

technical field [0001] The invention belongs to the 3D stereoscopic display technology in the field of optics, and specifically relates to a 3D projection film and / or application method applied on the surfaces of several types of television displays, smart phone displays, several types of computer displays, and projection lenses of projectors. Background technique [0002] Today's mainstream 3D stereoscopic display technology still can't free us from the shackles of special glasses, which makes its application scope and comfort are discounted. The current naked-eye 3D display technologies in the market mainly include parallax barrier technology, lenticular lens technology, MLD Although these technologies have their own advantages, their disadvantages are: the technology is still under development, the 3D stereoscopic display is bulky, and the product is not mature. Contents of the invention [0003] In order to solve the constraints and troubles of watching 3D stereoscopic...
