Anti-stealing 3D liquid crystal display, anti-stealing 3D glasses, liquid crystal display system and implementation method

Abstract

The invention discloses an anti-stealing 3D liquid crystal display, anti-stealing 3D glasses, a liquid crystal display system and an implementation method. The anti-stealing 3D liquid crystal display comprises an upper glass substrate and a lower glass substrate and a polaroid, wherein the polaroid is attached to the upper glass substrate, or the polaroid is attached to the lower glass substrate. The anti-stealing 3D glasses comprise lenses, wherein the lenses are polarized lenses, and the polarization direction of the polarized lenses is perpendicular to the polarization direction of the 3D liquid crystal display. According to the anti-stealing 3D liquid crystal display, the anti-stealing 3D glasses, the liquid crystal display system and the implementation method, only an operator who wears the 3D glasses can see the content displayed by the 3D liquid crystal display, the problem that the content displayed by the 3D liquid crystal display can be stolen easily is solved, and the safety of liquid crystal displaying is enhanced.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an anti-theft 3D liquid crystal display, glasses, a liquid crystal display system and an implementation method. Background technique [0002] Liquid crystal display LCD has been widely used in the field of display technology due to its flat display, stable and non-flickering image, low power consumption, light weight, and direct drive with large-scale integrated circuits. [0003] However, with the development of LCD technology, the brightness and viewing angle of LCD have been improved, but it also brings hidden dangers of privacy being peeped, especially the ATM automatic teller machine of the bank. The current ATM machines mostly use liquid crystal display or liquid crystal display touch screen, and the operator is easy to be stolen through the visible LCD display when operating, which is not conducive to the protection of the operator's own password. Therefore, it is necessa...

[0003] However, with the development of LCD technology, the brightness and viewing angle of LCD have been improved, but it also brings hidden dangers of privacy being peeped, especially the bank's ATM automatic teller machine

Most of the current ATMs use LCD screens or LCD touch screens. Operators are prone to steal passwords through visible LCD displays during operations, which is not conducive to the protection of operators for their own passwords. Therefore, existing LCD displays need to be Make improvements to prevent others from peeping on the operator's personal information
