According to a peep-proof display method based on wavefront distortion compensation, a tunable phase plate array covers the front portion of a displayer, screen light can penetrate through the phase plate array and generate wavefront distortion, and normal information displayed on a screen cannot be read no matter screen data is specially provided for a user or a scout person; and screen data is specially used for a user to wear wavefront distortion compensation glasses, screen light wavefront distortion generated by the phase plate is compensated, and the user can see the screen clearly. The phase distribution of the tunable phase plate array and the phase distribution of the wavefront distortion compensation glasses are always kept complementary, and the two parties are synchronous and consistent through a shared key for wireless communication interaction; and the scout person cannot know the content of the secret key, and screen information cannot be read in real time even if the scout person has the wavefront distortion compensation capability. According to the invention, technologies of wireless communication, key distribution, adaptive optics and the like are effectively combined, non-cooperative personnel are effectively prevented from peeping into security switching information displayed on a screen, and a brand new solution is provided for prevention of visual hackers in a mobile office environment.
Description
technical field [0001] The invention belongs to the interdisciplinary field of optoelectronics, display optics, adaptive optics and wireless communication, and specifically refers to a method of covering the front of a display with a phase plate to blur the screen, using wavefront distortion compensation glasses to restore screen information, and controlling The phase distribution of the phase plate and the wavefront distortion compensation glasses is synchronized in real time to realize the anti-peep display technology that only the screen data is exclusively for the user to see the screen clearly, especially relates to an anti-peep display method based on wavefront distortion compensation. Background technique [0002] The display of mobile phones and computers is an important medium for information processing platforms to realize human-computer interaction, and it is also the starting point for visual hackers to steal security-concerned information. In mobile office scena...
