Problems solved by technology

[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, they have their own disadvantages: the technology is still under development, the 3D stereoscopic display is bulky, and the products are immature

Embodiment 1

[0069] Embodiment 1, according to a structural scheme 2 of a 3D projection film,

[0070] On the upper surface of the film 1, there are several closely arranged in parallel, with the vertical center line of the film 1 as the boundary and parallel to the vertical edge of the film 1 or the vertical edge of the display, or with the horizontal center line as the boundary. The boundary is a triangular prism 2 parallel to the horizontal edge of the film 1 or the horizontal edge of the display, the cross section of the triangular prism 2 is a triangle, and there is a gap between the two sides and the base of the triangle in the cross section of the triangular prism 2. equal angles and the base of this triangle is on the upper surface of the film 1, the triangles of the cross-section of the triangular prism 2 on both sides of the median line are arranged symmetrically with the median line as the boundary, all the three The cross-sections of the prisms 2 are similar and / or equal in are...

Embodiment 2

[0072] Embodiment 2, according to a structural scheme 3 of a 3D projection film, on the upper surface of the film 1, there are several closely and neatly arranged bottom diagonal lines parallel to the corresponding sides of the film or the corresponding sides of the display. The bottom surface is a rhombus-shaped quadrangular pyramid 7, wherein the corresponding slopes of adjacent quadrangular pyramids 7 in the same row are in the same direction, and two adjacent rows of quadrangular pyramids 7 are closely spaced and neatly arranged, and each slope of the quadrangular pyramid 7 is closely aligned with the bottom surface. There is an angle between them, such as a 45 ° angle, the angle between the opposite slope and the bottom surface is equal, the angle between the adjacent slope and the bottom surface is equal, and the bottom surfaces of all the quadrangular pyramids 7 are similar and / or equal in area, so The base width of the quadrangular pyramid 7 is 1500 μm or several values...

Abstract

The invention discloses a 3D projection film and / or a utilization method and belongs to the field of optics and specifically belongs to the field of 3D stereoscopic display technologies. Shortcomings of conventional 3D display technologies can be solved. Key points of a technical solution of the 3D projection film and / or the utilization method are that an upper surface of the film is provided with a number of triangular prisms that are arranged in a close and orderly manner, the triangular prisms are parallel to a vertical edge of the film or a vertical edge of a display device, a cross section of each triangular prism is shaped as an isosceles triangle, a bottom side of the isosceles triangle is positioned on the upper surface of the film, two inclined planes of each triangular prism are provided with nano-scale photosensitive coatings, protection layers are arranged on the nano-scale photosensitive coatings, a bottommost layer of the film is provided with a highly transparent adhesive layer or adhesion layer, and the adhesive layer is flatly pasted on a surface of a display device; after a 3D stereoscopic film source of images or a video on the display device is reflected via the film disclosed in the invention, the images or the video seen by naked human eyes has 3D stereoscopic effects; the 3D projection film and / or the utilization method can be mainly applied to holographic 3D stereoscopic projection display of several kinds of display devices, several kinds of television display devices and projectors.

Description

technical field [0001] The invention belongs to the true three-dimensional 3D display technology in the field of optics, and specifically relates to a 3D projection film and / or using method applied on the surfaces of several types of TV 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 v...
