Embodiment Construction
[0026] Such as figure 1 As shown, the three-dimensional display device of the present invention includes a light source 1 , a light guide plate 2 and a light splitting structure 3 . The light source 1 is located on the side wall of the light guide plate 2, and the top of the light guide plate 2 is provided with a light splitting structure 3, wherein the inside of the light guide plate 2 has a first three-dimensional microstructure, and the surface of the light splitting structure 3 adjacent to the light guide plate 2 has a second 2D and 3D microstructures. These three-dimensional microstructures can be prisms, circles, circular frustums, cylindrical lenses, etc. and are not limited to fixed patterns, but can also be other three-dimensional patterns that can improve their optical properties. Such as Figure 6 with Figure 7 As shown, the second three-dimensional microstructure of this embodiment is a prism, Figure 6 with Figure 7 It is a picture taken under an optical mi...

The invention discloses a three-dimensional display device and belongs to the field of 3D display. The three-dimensional display device comprises a light source, a collimation backlight module and a light splitting structure, wherein the collimation backlight module comprises a light guiding plate; the light source is arranged on the side wall of the light guiding plate; and the light splitting structure is arranged at the front surface of the light guiding plate. The light source emerges to the side wall of the light guiding plate horizontally, is emerged into a surface light source with high collimation level and high brightness through a first three-dimensional microstructure in the light guiding plate; as the light guiding plate is the collimation backlight module, the emergent surface light source vertically enters the rear surface of the light splitting structure, the light emerges into different directions of light beams with included angles through a second third-dimensional microstructure in the light splitting structures, and then different directions of light beams are projected to different positions in the space so as to form multi-view three-dimensional display, even light-field type three-dimensional display. The three-dimensional display device disclosed by the invention has the advantages that the light splitting structures of the second third-dimensional microstructure are matched with the collimation backlight module to realize 3D display; and the structure is simple, the operation is convenient, the effect of the 3D images is better, the crosstalk is little, and the comfort level of a user is greatly improved.
Description
technical field [0001] The invention relates to a three-dimensional (3D) display technology, in particular to a 3D display technology based on a collimated backlight module and a light splitting structure. Background technique [0002] Three-dimensional stereoscopic display, as the next-generation new display technology vigorously developed by countries all over the world, is gradually becoming an eye-catching frontier technology field. In recent years, 3D stereoscopic display technology has been applied more and more in fields such as television broadcasting, video games, medical care, and education. 3D display has developed from movie screens to TV terminals, computer terminals, smart phone terminals, and tablet computer terminals. With the development of 3D display technology and the commercialization of products, the human visual experience will be innovated again, and the realistic reproduction of the real world and the virtual world will soon become a reality.
