Problems solved by technology

like Figure 4 As shown, in this system, the front polarizer 3 in the conventional display system is canceled, and the naked eye will not be able to see the displayed image due to the insensitivity of the human eye to the polarization phenomenon

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0032] Figure 5 Characteristic one of the display system of the present invention is demonstrated. On the side of the display system, the same Figure 4Similar structure: cancel the front polarizer, add a liquid crystal display control unit 22 on this basis to constantly randomly select N preset states of the display system, and in each preset state, there is a preset value of the polarization amount of the liquid crystal layer error. At the same time, the viewer 4 uses a polarizer 28 with an adjustable polarization direction. Only the polarizer 28 can match and compensate the error in the preset state of the display control unit 22 at a certain polarization angle, so as to display images correctly. Accordingly, the polarization direction of the polarizer 28 is controll...

Abstract

The invention provides an image display system and a method therefor. Original image information is encrypted into a number of shared images via an image encryption unit, the shared images are sent to a display control unit, the shared images are sent to a display unit for display via the display control unit according to a timing sequence, a random polarization state is adopted for displaying each shared image, a polarization angle is sent to a polarization direction control module by the display control unit via a communication unit, and the polarization direction control module enables an adjustable polaroid to realize the polarization angle. The image display system and the method therefor are free from blind area for information protection, a plurality of authorized viewers are allowed to view information at a wide angle, unauthorized users can be prevented from reading protected information via use of the polaroid or other similar optical apparatuses, and complete protection of the information can be realized.

Description

technical field [0001] The invention relates to an image display system, in particular to a display system based on a multi-state dynamic polarizing system and visual encryption technology. Background technique [0002] At present, liquid crystal display technology has been widely used in electronics such as desktop computer monitors, tablet computers, mobile phones and televisions. The main display components of a liquid crystal display panel include two linear polarizers, front and rear, and a liquid crystal layer sandwiched between them. Two linear polarizers usually have a fixed angle, which is close to or equal to a right angle. The display control circuit achieves different light transmittance by applying different voltages on the liquid crystal to change its polarization angle, and the light transmittance determines the gray scale of the display pixel. By controlling each pixel on this principle, the display of the constituent image can be realized. Such as figure...
