Problems solved by technology

It is understandable that under a fixed-resolution display, the greater the number of content items, the lower the resolution allocated to each group of left and right views, and the viewing experience is greatly reduced.
This solution is to increase the probability of the human eye in the effective viewing area by sacrificing the display resolution, and multi-eye shooting will also increase the difficulty and cost of production
In addition, although the space position of the effective viewing area of ​​this scheme can be changed, the area size of the effective viewing area does not change, resulting in a waste of part of the viewing area at the same distance, and the number of viewers that can be accommodated is reduced
Therefore, this solution is not conducive to the promotion and development of glasses-free 3D technology solutions

Embodiment 1

[0053] The naked-eye 3D display method of this embodiment is applied to a smart terminal. The display screen of the smart terminal is covered with an electronic 3D optical film. The electronic 3D optical film can be integrated on the display screen during the production process of the smart terminal, or after the smart terminal is generated. Paste it on the display. The electronic 3D optical film in this embodiment can adjust the grating constant; as an option, the electronic 3D optical film can be selected as electronic lenticular grating optical film, electronic barrier parallax grating optical film, etc., electronic lenticular grating optical film and For the structure of the electronic barrier parallax barrier optical film, reference may be made to the prior art, which will not be repeated in this embodiment. The smart terminal processes the 3D content according to the preset algorithm, and displays it on the display screen after processing. The light of the displayed imag...

Embodiment 2

[0072] refer to Figure 6 , on the basis of Embodiment 1, in the naked-eye 3D display method of this embodiment, after step S2 and before step S3, the method further includes:

[0073] S21. According to the spatial position information, it is judged whether all eyes are within the preset viewing area corresponding to the preset unit layout length. Because the length of the preset unit layout is fixed in this embodiment, the distance between the display screen and the electronic 3D optical film is a known amount. On this basis, according to the width of the effective viewing area, the length of the preset unit layout, the display screen and The distance of the electronic 3D optical film yields the grating constant of the electronic 3D optical film. After obtaining the preset viewing area corresponding to the preset unit layout length, judge whether all eyes are in the preset viewing zone corresponding to the preset unit layout length according to the spatial position informati...

Embodiment 3

[0077] refer to Figure 7 , on the basis of embodiment 1, in the naked-eye 3D display method of this embodiment, after step S2 and before step S3, it also includes:

[0078] S23. Judging according to the spatial position information whether all eyes can be viewed at the same time by adjusting the mobile layout of the display screen, that is, judging whether all eyes can be located in the effective viewing area by adjusting the mobile layout of the display screen according to the spatial position information Within the range, wherein the mobile layout includes the left and right displacement of the layout and / or the up and down displacement of the layout, the adjustment can be completed only through the left and right displacement of the layout, or the adjustment can be completed only through the up and down displacement of the layout, or at the same time through the left and right displacement of the layout and the up and down displacement of the layout to complete the adjustm...

Abstract

The invention relates to a naked eye 3D display method and an intelligent terminal. The method is applied to the intelligent terminal, a display screen of the intelligent terminal is covered with an electronic 3D optical film, and the intelligent terminal is in communication connection with the electronic 3D optical film. The method comprises the following steps: S1, enabling the intelligent terminal to perform initialization display on a display screen according to a preset unit layout length; S2, acquiring spatial position information of at least one group of human eyes in front of the display screen; S3, calculating an effective visual area width according to all the spatial position information; S4, obtaining a target grating constant of the electronic 3D optical film according to theeffective visual area width; S5, adjusting the grating constant of the electronic 3D optical film to a target grating constant. According to the invention, multi-view shooting is not needed to increase the number of the 3D content, and the grating constants of the electronic 3D optical film are adjusted by obtaining the spatial position information of multiple groups of human eyes, so multiple persons can watch at the same time, the resolution is not reduced, the cost is low, and the effect is good.

Description

technical field [0001] The present invention relates to the field of naked-eye 3D, and more specifically, relates to a naked-eye 3D display method and an intelligent terminal. Background technique [0002] Because naked-eye 3D display technology does not require users to wear 3D glasses to watch, the user experience is greatly improved, but there are still problems to be solved when multiple people watch the same display screen at the same time. According to the principle of naked-eye 3D display, it can be known that different viewers at different positions in front of the naked-eye 3D display panel can see different images with their left and right eyes. When multiple people watch naked-eye 3D content at the same time, some people’s eyes are easily in the wrong viewing area, causing the left eye to see the content of the left viewpoint and the content of the right viewpoint at the same time (the same is true for the right eye). There will be ghosting on the screen, and the...
