An embodiment of the present invention provides a display device, including: a backlight module, the backlight module includes a first light source; a first polarizer, the first polarizer is located on a light-emitting side of the backlight module; a liquid crystal module , the liquid crystal module is located on the side of the first polarizer away from the backlight module, including: the opposite array substrate and the opposite substrate, and between the array substrate and the opposite substrate a liquid crystal layer; a second polarizer, which is located on the side of the liquid crystal module away from the first polarizer; a quantum dot film layer, which is located on the second polarizer the side away from the liquid crystal module.

Description

technical field [0001] The present invention relates to the field of display, and in particular, to a display device, a display system and a display method. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of low radiation, small size and low energy consumption, and has gradually replaced the traditional cathode ray tube display (CRT) in some applications, so it is widely used in Notebook computers, personal digital assistants (Personal Digital Assistant, PDA), flat-screen TVs and mobile phones and other products. [0003] With the rapid development of science, data security and privacy have become a major problem, especially in some application environments where privacy needs to be protected in public places, such as ATMs, etc., data security and privacy protection are important to everyone. However, the display devices in the prior art are mainly visible displays, and there are few display devices that realize concealed display. SUMMARY OF ...
