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 large field of view, it has inherent defects such as difficult calibration between projectors and high cost.

Embodiment 1

[0030] refer to figure 1 Embodiment 1 of the true three-dimensional display device of the present invention includes a light source 10 and the first light-transmitting layer to the N-th light-transmitting layer 12 sequentially arranged along the light propagation direction of the light source 10, where N is an integer greater than 1, and each light-transmitting layer The optical layer 12 is used to display the tomographic image corresponding to the predetermined field of view, and the tomographic images corresponding to the predetermined field of view displayed by each light-transmitting layer 12 are used to form a true three-dimensional image corresponding to the predetermined field of view.

[0031] The number of the above preset fields of view can be multiple, such as figure 1 As shown, the true three-dimensional display device of the present invention can form a plurality of fields of view V1, V2...VR, R is an integer greater than 1, and the light projected into each field...

Embodiment 2

[0038] refer to figure 2 Embodiment 2 of the true three-dimensional display device of the present invention includes a light source 20 and N light-transmitting layers 22 arranged along the light propagation direction of the light source 20. The true three-dimensional display device of this embodiment is the same as the true three-dimensional display device of embodiment 1. The structure is basically the same, the difference is:

[0039] Each light-transmitting layer 22 is a polar light rotator, and its light processing parameter is specifically a function of rotation rate. Each polar light rotator is used to receive external control information to control the rotation rate function value of each display unit to the light, and then display the required image information (tomographic image).

[0040] Optionally, when the light emitted by the light source is divergent light, a first polar light modulator 24 is also arranged between the light source and the first polar light rot...

Embodiment 3

[0045] refer to image 3Embodiment 3 of the true three-dimensional display device of the present invention includes a light source (not shown in the figure) and an Nth light-transmitting layer 32 arranged along the light propagation direction of the light source 0, and each light-transmitting layer 32 can be a spatial light modulator , a polar light rotator or other devices that can adjust the display content of the tomographic image. When each light-transmitting layer 32 is a polar light rotator, the true three-dimensional display device of this embodiment also includes a first polar light modulator and a first polar light modulator. The second polar light modulator has been specifically described in Embodiment 2 and will not be repeated here.

[0046] The true three-dimensional display device of this embodiment has basically the same structure or working mode as the true three-dimensional display device of embodiment 1 or embodiment 2, the difference is that, as image 3 As...

Abstract

The invention provides a true three-dimensional display device and system, a true three-dimensional display control method and apparatus. The true three-dimensional display control method comprises: according to a preset view field, target light is determined, wherein specifically, the target light is one that is generated by a light source and can penetrate N light-transmitting layers successively and be projected in the preset view field and N is an integer larger than 1; and according to coordinate information of all target light at all light-transmitting layers, optical processing parameters of all light-transmitting layers are adjusted, thereby displaying a faultage image for forming a true three-dimensional image corresponding to the preset view field. According to the invention, performances of definition and resolution ratio brightness and the like of true three-dimensional display can be improved.

Description

technical field [0001] The present invention relates to image display technology, in particular to a true three-dimensional display device and system, and a true three-dimensional display control method and device. 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, which has the surface characteristics of real physical depth and image quality, and the observer does not need any The auxiliary device can observe the displayed object arbitrarily from multiple directions, and perceive the most real and complete three-dimensional information. 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 spa...
