High-privacy liquid crystal displaying component

Abstract

The invention relates to the field of liquid crystal displaying, in particular to a classified liquid crystal displaying component. The high-privacy liquid crystal displaying component comprises a liquid crystal displaying screen and screen-watching glasses. The liquid crystal displaying screen comprises a backlight module, a lower glass substrate, a TFT liquid crystal module, an upper glass substrate and a horizontal polarizing film which are arranged in the light-moving direction in an overlapping mode. The horizontal polarizing film is attached on a light-out face of the upper glass substrate. The screen-watching glasses comprise vertical polarizing films and spectacle lenses which are arranged on a glasses frame, and the vertical polarizing films are attached on the spectacle lenses and are matched with the horizontal polarizing film. According to the high-privacy liquid crystal displaying component, the polarizing films which are originally matched with the liquid crystal displaying screen are detached and are attached on the spectacle lenses, so that the spectacle lenses and the liquid crystal displaying screen become one set of component, the content of the liquid crystal displaying screen can be seen only during pair matching, displaying screen content revealing can be effectively avoided even in public places, and safety is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a confidential liquid crystal display component. Background technique [0002] Liquid crystal is a substance between solid and liquid, and is an organic compound with regular molecular arrangement. Simply put, the principle of liquid crystal display is that when the liquid crystal between the two electrodes is energized, the arrangement order of the liquid crystal molecules will change when the electrodes are energized, thereby changing the optical path of the transmitted light and realizing the control of the image. [0003] Liquid crystal displays have gradually eliminated traditional CRT displays due to their small size, thinness, low power consumption, stylish appearance, and low radiation. The structure of the existing liquid crystal display is usually as follows figure 1 It includes a backlight module 1, a vertical polarizing film 2, a lower glass substrate 3, a TFT ...

AI Technical Summary

Problems solved by technology

This type of liquid crystal display has the same feature as the traditional CRT display, that is, anyone can see the screen content within the visible range of the display screen. When operating confidential documents in public places and other places, there will be a risk of leakage, which cannot meet the needs of this group of people
