Embodiment 1

[0036] An embodiment of the present invention provides a holographic display system, such as figure 1 As shown, the holographic display system includes a display device 1 and anti-peeping glasses 2 , and the anti-peeping glasses 2 are used in conjunction with the display device 1 .

[0037] Wherein, the display device 1 includes a backlight 3 , a data processor 6 and a first spatial light modulator 5 . The backlight 3 is used to generate laser beams. The data processor 6 is used to generate holographic encoded data according to the holographic three-dimensional image information to be displayed, and divide the holographic encoded data into synchronous first sub-holographic encoded data and second sub-holographic encoded data. The first spatial light modulator 5 is connected to the data processor 6, and the first spatial light modulator 5 includes a plurality of first pixels 51, and the first spatial light modulator 5 is used for, according to the first sub-holographic coded d...

Embodiment 2

[0058] An embodiment of the present invention provides a holographic display system, which is similar in structure to the holographic display system provided in Embodiment 1. The difference is that in the holographic display system provided in this embodiment, the first sub-holographic The encoded data carries amplitude information, and the second sub-holographic encoded data carries phase information. Corresponding to this situation, for example Figure 5 As shown, the first spatial light modulator 5 of the display device of the holographic display system in this embodiment includes a fifth substrate 22 and a sixth substrate 23 oppositely arranged, and the fifth substrate 22 is arranged on the first spatial light modulator 5 On the light incident side, a third liquid crystal layer 24 is arranged between the fifth substrate 22 and the sixth substrate 23, a third polarizer 27 is arranged on the surface of the fifth substrate 22 facing away from the sixth substrate 23, and the fi...

Embodiment 3

[0065] An embodiment of the present invention provides a holographic display method, which is used in a holographic display system. The holographic display system includes a display device and anti-peeping glasses, the display device includes a plurality of first sub-pixels, and the anti-peeping glasses includes a plurality of second sub-pixels. Such as Figure 7 As shown, the holographic display method includes the following steps:

[0066] Step S101: Generate holographic encoded data according to the holographic three-dimensional image information to be displayed, and divide the holographic encoded data into synchronous first sub-holographic encoded data and second sub-holographic encoded data.

[0067] Step S102: providing laser beams to each of the first pixels, and modulating the laser beams incident on each of the first pixels according to the first sub-holographic encoding data.

[0068] Step S103: according to the second sub-holographic encoding data, modulate the la...

Abstract

The invention discloses a holographic display system and a holographic display method, relates to the technical field of display, and can prevent other persons from obtaining holographic three-dimensional image information and ensure the safety of user information when providing the holographic three-dimensional image information for a user. The holographic display system comprises a display device and a pair of peep-proof spectacles, wherein the display device comprises backlight for generating laser beams, a data processor and a first spatial light modulator, wherein the data processor is used for generating holographic coding data according to to-be-displayed holographic three-dimensional image information, and dividing the holographic coding data into first sub-holographic coding data and second sub-holographic coding data; and the first spatial light modulator comprises multiple first pixels and is used for modulating the laser beams emitted into each first pixel according to the first sub-holographic coding data. The pair of peep-proof spectacles comprises a second spatial light modulator, wherein the second spatial light modulator is connected with the data processor, comprises multiple second pixels and is used for modulating the laser beams emitted into the each second pixel according to the second sub-holographic coding data. The holographic display system and the holographic display method provide safe holographic three-dimensional information for the user.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a holographic display system and a holographic display method. Background technique [0002] At present, in order to improve the user's viewing experience, the display system is often designed to have the function of providing the user with three-dimensional image information. Specifically, the working process of the display system with the above functions is as follows: project the light emitted by the pixel row displaying the image for the left eye to the left eye of the observer, and project the light emitted by the pixel row displaying the image for the right eye to the right eye of the observer. Eyes, so that the observer can synthesize three-dimensional image information in the brain according to the left eye image observed by the left eye and the right eye image observed by the right eye. [0003] However, the inventors of the present application found that altho...
