However, in a mobile office scenario, it is inevitable that the screen is peeped by a non-partner; if the surrounding situation is noticed at any time in order to ensure that the patient is not peeped, the working efficiency will be greatly reduced.

As shown in fig. 1, the invention discloses a binocular parallax compensation peep-proof display principle embodiment based on polarization regulation. Under normal conditions, screen display content is incident on the human eye in the form of screen light and is imaged on the retina. In fig. 1, the screen display content generates a blurring effect after passing through a blurring processing film, and the specific principle is as follows:

1. the screen light is converted into linearly polarized light after passing through the polarizer;

2. the screen light is divided into two beams after passing through the polarization beam splitter, wherein one beam is transmitted by deflecting for 90 degrees, the other beam is transmitted along the original path, the polarization direction of the polarizer and the polarization direction of the beam splitter form an included angle of 45 degrees, and then the powers of the two beams of screen light are equivalent;

3. polarization modulation is carried out on the two beams of screen light components through a polarization rotator, and the polarization directions of the two beams of screen light components are always kept orthogonal;

4. the prism group is utilized to combine the screen light components of two adjacent paths of screen light with different polarization states and output a fuzzification processing film, and at the moment, an output light field comprises two screen images with different polarization states, and a certain spatial offset exists, so that a fuzzy effect is generated.

The screen data is specially used for users to wear binocular parallax compensation glasses, the thicknesses of the left lens and the right lens are different, and the thickness difference can exactly compensate the spatial deviation of the light components of the two beams of screens. Meanwhile, the left lens and the right lens of the double-sided parallax compensation glasses have the functions of polarization adjustable analyzers, the polarization directions of the left lens and the right lens are respectively consistent with the polarization directions of the two beams of screen light components, and therefore the left lens and the right lens can only penetrate through one beam of screen light components and inhibit the other beam of screen light components with the maximum extinction ratio. Through synchronous modulation module and wireless communication module, can make two bundles of screen light component polarization directions change time at random, and concrete implementation mode does: the synchronous modulation module generates symmetrical synchronous modulation signals, wherein one path of the synchronous modulation signals is in a polarization direction in which two beams of screen light components are randomly distributed at the fuzzification processing film, the other path of the synchronous modulation signals is sent to the binocular parallax compensation glasses through the wireless communication module and is converted into a lens polarization direction through compiling, and the synchronous modulation module continuously updates the synchronous modulation signals, so that the left lens and the right lens can respectively penetrate through one beam of screen light components at the highest transmittance and block the other beam of screen light components at the maximum extinction ratio. The screen data is specially used for the left eye and the right eye of a user to see a consistent clear screen through the compensation effect of the optical path difference of the left lens and the right lens on the spatial deviation of the light components of the two beams of screens; even if the viewer can use the analyzer to filter out one of the screen light components, the viewer cannot keep the parallel synchronization of the polarization directions due to the lack of the synchronous modulation link, i.e. cannot see the screen content stably for a long time. The screen information is specially provided for a user to see the screen clearly through the polarized glasses, and the premise is that the polarization direction of the polarized glasses is always parallel to the polarization direction of one of the screen light components. It should be noted that the synchronous modulation module can also be used to implement dynamic binocular disparity compensation, i.e. the spatial offset of the two beams of screen light components and the optical path difference of the left and right lenses of the binocular disparity compensation glasses are controlled simultaneously, so that the dynamically changing optical path difference of the left and right lenses can compensate the dynamically changing spatial offset of the two beams of screen light components in real time.

and finally, distributing synchronous modulation signals for the binocular parallax compensation glasses and the fuzzification processing film in real time through a wireless communication means, compiling the synchronous modulation signals into random rotation amount of polarization direction of two beams of screen light components and random rotation amount of polarization direction of the corresponding binocular parallax compensation glasses, or simultaneously compiling the synchronous modulation signals into space deviation of random change of the two beams of screen light components and optical path difference of the binocular parallax compensation glasses, so that screen data are ensured to be specially used by a user to clearly see the screen without disturbance all the time, other peepers can not stably see the screen all the time, and the peeping prevention display effect is achieved.
