Embodiment 1

[0079] Embodiment 1, according to the structural scheme seven of a 3D stereoscopic projection film, as follows, the side length of the square film 1 is 14.5 cm, the width is 6.9 cm, and the thickness is 0.33 mm. On the upper surface of the square film 1, there are several The bottoms of the bottoms arranged in close order in parallel and the bottoms parallel to the corresponding sides of the square film 1 are square identical regular pyramids, and the bottoms of each of the regular square pyramids are on the upper surface of the square film 1, The height of each regular quadrangular pyramid is 0.5 millimeters, and the base width of the bottom surface is 1 millimeter, and each slope forms an angle of 45 ° with the bottom surface, and the thickness of the adhesive layer and / or adhesion layer 3 on the lower surface of the square film 1 is 0.09 mm. mm, paste the adhesive layer and / or adhesion layer 3 of the square film 1 on the surface of the smart phone display, one side of the sq...

Embodiment 2

[0081] Embodiment 2, according to a structural scheme 3 of a 3D stereoscopic projection film, the description is as follows,

[0082] The width of the square film 1 is 60 centimeters, the height is 30 centimeters, and the thickness is 0.15 to 0.7 millimeters. On the upper surface of the square film 1, the midpoint of a base of the square film 1 and the The square membrane 1 is divided into two congruent triangles and a larger triangular membrane area by two lines connecting two vertices of the other base parallel to the other base, and in the larger triangular membrane area There are several identical triangular prisms 2 that are closely arranged in parallel and parallel to the bases of the larger triangular membrane regions on the upper surface, and there are several closely spaced triangular prisms 2 on the upper surface of the two congruent triangular membrane regions. The same triangular prisms 2 parallel to the vertical sides of the square film 1 arranged in parallel, one...

Abstract

The invention discloses a 3D stereoscopic projection film, and belongs to the field of optics, in particular to 3D stereoscopic projection display technology of display devices. The technical scheme mainly comprises that the upper surface of a square film is provided with a plurality of rows of identical rectangular pyramids that are aligned closely, orderly and parallelly and have square bottom surfaces, base edges of the bottom surfaces of the rectangular pyramids are parallel with corresponding sides of the square film respectively, the bottom surface of each rectangular pyramid is on the upper surface of the square film, 4 side faces of all the rectangular pyramids are provided with protective layers, the bottom surface of the square film is provided with an adhesive layer and / or adhering layer, and the adhesive layer and / or adhering layer is stuck to the surface of a display flatly, so that an intersection of 2 diagonal lines of the square film overlaps with an intersection of 2 diagonal lines of a display area of the display. After reflection and / or refraction of a 3D film source by the square film, an image and / or video seen with naked eyes has a 3D stereoscopic effect. Mainapplication of the 3D stereoscopic projection film comprises 3D stereoscopic projection display of a plurality of displays and projectors for naked eyes.

Description

technical field [0001] The invention belongs to the 3D stereoscopic image and / or video projection display technology in the field of optics, and specifically relates to a 3D stereoscopic projection applied to the surfaces of several types of television displays, smart phone displays, several types of computer displays, and projection lenses of projectors membrane. Background technique [0002] Today's mainstream 3D stereoscopic projection display technology still cannot free us from the shackles of special glasses. MLD technology, pointing light source technology and other technologies, although these technologies have their own advantages, but disadvantages: the technology is still under development, 3D stereoscopic display is bulky, and the product is immature. Contents of the invention [0003] In order to solve the constraints and troubles of watching 3D stereoscopic TV and / or video with glasses, overcome the shortcomings of existing 3D stereoscopic display technology...
