Abstract

The invention provides an anti-peeping display system based on rotary polaroids, relates to the technical field of liquid crystal display, and aims at solving the problems that in the anti-peeping display technology, the existing anti-peeping display technology is poor in anti-peeping performance and safety, large in technological difficulty and high in production cost. The system comprises the first polaroid, a first motor, a liquid crystal module, a first control module and polaroid glasses. The liquid crystal module comprises a TFT array plate, a liquid crystal box and a color filtering plate. A signal sending device is included in the first control module. The polaroid glasses comprise the second polaroid, the third polaroid, a first transmission rod, a second transmission rod, a second motor, a second control module and a polaroid manual adjusting knob. A signal receiving device is included in the second control module. The decoding difficulty of display content for a peeper is increased through the changes of the rotating speeds of the polaroids.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a peep-proof display system based on a rotating polarizer. Background technique [0002] With the development of science and technology, the level of liquid crystal display technology has improved rapidly. While people are pursuing high-quality and high-resolution displays, more and more people pay more and more attention to the privacy and security of displayed content. Especially in some special places, such as: military units, technology research and development units, banks, etc., information security is particularly important. The harm caused by the content of the display being peeped by others abounds. Therefore, it is necessary to develop an anti-peeping display system with high safety, stable performance, little modification to existing production equipment, and relatively low production cost. [0003] Existing anti-spy displays can be roughly divided in...
