Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic cross-sectional structure diagram of a 3D display device according to a first embodiment of the present invention, where the device 10 includes:
a substrate 11;
the display device comprises at least one display unit 12 arranged on the substrate 11, wherein each display unit 12 corresponds to a 3D display picture, when the display unit 12 is irradiated by a light source at a preset angle, incident light is reflected, and the reflected light forms the 3D display picture.
By adopting the device, the invention can realize real three-dimensional image display and obtain a three-dimensional 3D display image, and the application scene is wider.
The 2 display units in fig. 1 are only exemplary, and the 3D display device of the present invention may include 1 or more than 1 display unit, and the number of the display units is not limited.
The following describes a specific structure of the display unit by way of example.
In some preferred embodiments of the present invention, the display unit 12 includes a plurality of sub-pixel units 20, referring to fig. 2, each sub-pixel unit 20 corresponds to a display information in the 3D display frame, and each sub-pixel unit 20 includes:
a reflective layer 21 on the substrate 11;
a transparent material layer 22 on the reflective layer 21;
a liquid crystal layer 24 covering the metal nanorods 23;
the thickness of the transparent material layer 22, the size and the setting angle of the metal nanorods 23, and the deflection angle of the liquid crystal molecules in the liquid crystal layer 24 satisfy that when the sub-pixel unit 20 is illuminated by a light source at a predetermined position at a predetermined angle, the reflected light can form display information corresponding to the sub-pixel unit 20.
Wherein, the reflecting layer 21 is used for reflecting light; the transparent material layer 22 is used for light penetration; the metal nano-rod 23 is used for controlling the imaging of the reflected light, and enabling the light with a specific wavelength to pass through, so that the unnecessary light cannot pass through, and the displayed image presents corresponding colors; the liquid crystal layer 24 serves to control light transmittance.
The structure of the sub-pixel unit 20 is a metamaterial, which has a special property not possessed by a natural material because the metamaterial has an artificial composite structure having extraordinary physical properties not possessed by a natural material. By utilizing the light manipulation of the metamaterial, the angle of the reflected light can be different when the light source at the preset position irradiates the 3D display device 10 at the preset angle, so that the purpose of imaging at the specific position is achieved, and the three-dimensional image display can be really realized. The principle of stereoscopic imaging is briefly explained below.
Referring to fig. 3, if the incident light irradiates on the metal nanorods 23, the light is directly reflected out; if the incident light irradiates on the transparent material layer 22, the light first propagates in the transparent material layer 22 and is reflected by the reflective layer 21, and then the reflected light exits the transparent material layer 22. Because the metal nanorods 23 are arranged at different angles, the outgoing angles of the reflected light rays are different, and the outgoing angles of the reflected light rays are different due to the different incident positions and angles of the incident light rays, the propagation of the light rays can be controlled by controlling the arrangement angles of the metal nanorods 23 and the positions and angles of the 3D display device 10 irradiated by the incident light rays, the outgoing light rays at different angles can be obtained, and the three-dimensional 3D display image can be obtained. In addition, as the sizes of the metal nanorods 23 are different, the positions of the formed 3D display images are also different, and the sizes of the metal nanorods 23 can be adjusted according to different application scenes, so that the imaging effect of the 3D images is optimal, and the application of the 3D holographic technology is wider.
Referring to fig. 4, the arrangement angle of the metal nanorods 23 is an included angle between the length direction of the metal nanorods 23 and the set direction parallel to the substrate plane, for example: the length direction of the metal nano-rod 23 forms an included angle phi with the x-axis.
In the above embodiments, the reflective layer 21 may be made of a metal material. Preferably, the reflective layer 21 and/or the metal nanorods 23 are made of gold. Of course, in other preferred embodiments, the reflective layer 21 and/or the metal nanorods 23 can also be made of other metals (e.g., silver or copper), and the invention is not limited thereto.
In some preferred embodiments of the present invention, the substrate 11 is a flexible substrate.
In other preferred embodiments of the present invention, the 3D display device 10 includes a plurality of display units 12, and the plurality of display units 12 are arranged in series in the same direction and connected two by two, so that the 3D display device 10 is formed in a band shape, and when the substrate 11 is a flexible substrate, the 3D display device 10 is similar to a motion picture film, see fig. 5.
In the above embodiments, one display unit corresponds to one 3D display frame, and the structure of each display unit corresponds to the 3D display frame corresponding to the display unit. A method of how to determine the structure of each display unit is explained below.
