Embodiment Construction
[0022] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0023] A two-dimensional microlens array can reproduce full parallax images, and its principle is as follows figure 1 As shown, when the image is recorded, the images of different viewing angles generated by each microlens unit are recorded. When the image is reproduced, the outgoing rays of the multi-viewing image elements are reproduced in front of the microlens array. Reconstructing up to thousands of viewing angles can achieve full parallax, that is, there is horizontal and vertical parallax, forming a complete 3D image, and providing motion parallax information.
[0024] When describing the microlens array morphology, the equation can be int...

The invention provides a naked-eye three-dimensional display device. The device comprises a display component and a visual angle regulation and control device, wherein the display component comprisesa display unit array formed by the array arrangement of a plurality of display units; and the visual angle regulation and control device comprises a visual angle regulation and control unit array formed by arranging a plurality of visual angle regulation and control units in an array mode, each visual angle regulation and control unit corresponds to a plurality of display units, the display unitsare divided into a plurality of groups, light rays emitted by each group of display units are converged into one visual angle through the visual angle regulation and control device, light rays emittedby different groups of display units are converged into different visual angles through the visual angle regulation and control device, each display unit in each group of display units corresponds todifferent visual angle regulation and control units, and the plurality of display units corresponding to each visual angle regulation and control unit are divided into different groups. In this way,different three-dimensional display effects can be achieved when a user watches at different visual angles, and a full-parallax image can be reproduced.
Description
technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a naked-eye three-dimensional display device. Background technique [0002] As one of the main sources of information for human beings, vision is particularly important in daily life. Unlike natural scenes, traditional display devices can only present two-dimensional images at present. This lack of depth of plane information to a certain extent limits human exploration and cognition of the vast world. Studies have shown that almost 50% of the human brain is used to participate in the processing of visual information, and the presentation of two-dimensional images leads to a decrease in brain utilization. Glasses-free 3D (three dimensional, 3D) display has great application value in film and television, games, education, vehicle, aviation, medical treatment, and military affairs. Taking the military field as an example, the visualization of 3D images is requir...
