Abstract

The invention discloses a display device, a display system and a display method. The display device is capable of realizing hidden display. The display device provided by the embodiments of the invention comprises a backlight module, a first polaroid, a liquid crystal module, a second polaroid and a quantum dot film layer; the backlight module comprises a first light source; the first polaroid islocated on the light outgoing side of the backlight module; the liquid crystal module is located on one side of the first polaroid, wherein the one side of the first polaroid is far away from the backlight module; the liquid crystal module comprises an array substrate, an alignment substrate and a liquid crystal layer, wherein the array substrate and the alignment substrate are opposite to each other, and the liquid crystal layer is located between the array substrate and the alignment substrate; the second polaroid is located on one side of the liquid crystal module, wherein the one side of the liquid crystal module is far away from the first polaroid; and the quantum dot film layer is located on one side of the second polaroid, wherein the one side of the second polaroid is far away fromthe liquid crystal module.

Description

technical field [0001] The present invention relates to the display field, in particular to a display device, a display system and a display method. Background technique [0002] Liquid crystal display (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 (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 that require privacy protection in public places, such as self-service teller machines, etc., data security and privacy protection are very important. However, the display devices in the prior art are mainly for visible display, and there are few dis...
