Problems solved by technology

[0003] The current binocular stereo glasses technology, parallel blocking grating technology, cylindrical mirror technology and integrated display technology all have various defects, such as small display size, small number of fields of view, low resolution, low brightness, insufficient clarity, etc.
Although the multi-projector light field true 3D display system has the potential to obtain a larger field of view, it has inherent defects such as difficult calibration between projectors and high cost.

Embodiment 1

[0027] refer to figure 1 , the true three-dimensional display device provided by the present invention includes:

[0028] light source 101;

[0029] N light modulation layers arranged in sequence along the propagation optical path of the light, N is an integer greater than 0, each of the light modulation layers is used to display the tomographic image synthesized by time division and modulate the light incident in different directions, so that different Light rays in different directions pass through each light modulation layer in turn, and form light field distributions in target viewing fields corresponding to different direction areas, so as to form true three-dimensional image information corresponding to corresponding target viewing fields.

[0030] The light source 101 is disposed close to one side of the first light modulator layer 102, and the other side of the first light modulation layer is disposed with a light splitting component.

[0031] Such as figure 1 As sh...

Embodiment 2

[0038] refer to figure 2 The true three-dimensional display device provided by the present invention includes a light source 201 and two light modulation layers sequentially arranged along the propagation optical path of the light. The structure of the true three-dimensional display device in this embodiment is basically the same as that in embodiment 1. The difference is that:

[0039] The light source 201 is arranged close to one side of the first light modulator layer 202 , and the other side of the first light modulation layer 202 is provided with a light-splitting component, and the light-splitting component is a microlens array 203 .

[0040] The first light modulation layer 202 is arranged close to the side of the light source 201, and the illumination light emitted by the light source 201 passes through the first light modulation layer 202 and the microlens array 203 to generate illumination light with controllable directions. This series of illumination light with di...

Embodiment 4

[0051]The true three-dimensional image display device provided in this embodiment includes a light source 401 and N light modulation layers arranged on the illumination light path of the directional light source, where N is an integer greater than 0. The true three-dimensional image display device provided in this embodiment and the true three-dimensional image The structure of the third embodiment of the display device is basically the same, the difference is that part of the light modulation layer in the true three-dimensional image display device provided by this embodiment is a polar light rotator.

[0052] Specifically, the light source 401 is arranged close to the side of the spatial light modulator 402, and the other side of the spatial light modulator 402 is provided with a microlens array 403 (or cylindrical mirror array), and the first polar light rotator There is a first polar light modulator 404 that converts the light generated by the light source 401 into polar li...

Abstract

The invention provides a true three-dimensional display device and a display control method, device and system. The display device comprises a light source and N light modulation layers which are arranged in sequence along the ray spread optical path, N being an integer larger than 0. Each light modulation layer is used for displaying faultage images composited at divided time and modulating the rays incident from different directions respectively so as to enable the rays of different directions to penetrate through the light modulation layers in sequence and form optical field distribution in target view fields corresponding to different direction areas, and thus true three-dimensional image information corresponding to the corresponding target view fields is formed. Therefore, the true three-dimensional display method can realize large-size displaying, improve resolution, brightness and sharpness and the like of the true three-dimensional display, and meanwhile, helps to prevent the problem of high difficulty in true three-dimensional display calibration carried out by utilizing the multi-projector.

Description

technical field [0001] The present invention relates to image display technology, in particular to a true three-dimensional display device, a display control method, device and system. Background technique [0002] The so-called "true three-dimensional display" means that the relative positional relationship between the displayed three-dimensional objects is also truly reflected, forming a real three-dimensional space image, with real physical depth and surface characteristics of image quality, and the observer does not need to With the help of any device, the displayed object can be observed from multiple directions arbitrarily, and the most real and complete three-dimensional information can be perceived. True 3D display technology fundamentally updates the concept of image display, makes the displayed image lifelike, provides complete psychological and physiological 3D perception information to the viewer, and provides a basis for understanding the spatial relationship be...
