Embodiment 1

[0033] Such as figure 1 As shown, Embodiment 1 provides a naked-eye 3D display method, which mainly includes the following steps:

[0034] (1): The image display layer is divided into several display units, and on one side of the image display layer, according to the optimal backlight position arc calculated in advance, a light-emitting module is arranged for each display unit according to the arc ;

[0035] In some preferred embodiments, a light-shielding layer can also be arranged between the display units to reduce stray light, thereby reducing the crosstalk rate;

[0036] (2): The human eye detection module detects in real time the spatial position and the observation angle of the observer's eyes relative to the image display layer to obtain the observation state of the observer;

[0037] (3): The human eye detection module selects the corresponding light-emitting module to emit light according to the observation state, and adjusts the light-emitting intensity to obtain ...

Embodiment 2

[0045] see figure 2 , figure 2 It is a structural schematic diagram of one of the display units of a naked-eye 3D display system according to the present invention, which includes an image display layer 22, a lens array film layer 21, a backlight 10, and a human eye detection module, which is used for detection and observation The spatial position and viewing angle of the viewer's human eyes relative to the image display layer. The film layer 21 includes an array formed by a plurality of lens units. The image display layer 22 is divided into several display units according to the lens units. The backlight unit 10 includes several light-emitting modules, and the light-emitting modules are arranged corresponding to the display units. A light-emitting module includes several rows of light-emitting units that can be independently controlled. The light-emitting units together form an arc-shaped light-emitting concave surface facing the lens unit. The curved surface is optimized...

Embodiment 3

[0051] This embodiment provides a naked-eye 3D display device, including:

[0052] The configuration module is used to configure several light-emitting units independently for each display unit in the direction perpendicular to the image display layer according to the arrangement of the light-emitting units calculated by simulation. Place an opaque partition between them to block crosstalk light;

[0053] The detection module is used to detect the spatial position and observation angle of the human eyes of the observer relative to the image display layer, so as to obtain the observation state of the observer;

[0054] The adjustment module is used to select a combination of light-emitting units corresponding to a suitable viewing area for projection according to the observation state and the division of the viewing area according to the simulation results.

[0055] The naked-eye 3D display device provided in this embodiment can independently configure a number of light-emitti...

Abstract

The invention provides a naked-eye 3D display method, a display system and a simulation analysis method of the display system. The display system comprises an image display layer, a lens array film layer, a backlight source and a human eye detection module. The lens array module is arranged between the image display layer and the backlight source; the image display layer comprises at least one display unit; the backlight source comprises at least one light-emitting module; the at least one display unit is in one-to-one correspondence with the at least one light-emitting module; for the system comprising the multiple display units, shading layers are arranged between the light-emitting modules to reduce crosstalk rate; the human eye detection module is connected with the light-emitting modules; and the human eye detection module is used for detecting the observation state of the eye of an observer, and selecting the light-emitting module corresponding to an appropriate visual area for projection according to the observation state of the observer. The naked-eye 3D display system can select appropriate light-emitting unit combination by detecting the spatial position and observation angle of the eye of the observer with respect to the image display layer, so that the human eye can obtain an optimal watch effect.

Description

technical field [0001] The invention relates to a naked-eye 3D display method, a display system and a simulation analysis method of the display system, belonging to the field of stereoscopic image display. Background technique [0002] Glasses-free 3D display technology is an important direction in the development of the display field, and has broad application prospects in scientific research, industry and entertainment. Most of the mainstream glasses-free 3D display technologies currently on the market, including parallax barriers, cylindrical lens gratings, and directional light sources, are all free stereoscopic display technologies based on the principle of binocular parallax. Make viewers feel 3D images with a sense of depth. [0003] The crosstalk rate is one of the core indicators for evaluating the naked-eye 3D display effect and viewing comfort, and reflects the obvious degree of ghosting on the display. The crosstalk rate refers to the degree to which the image ...
