Abstract

The invention discloses a transparent display device. The transparent display device comprises a transparent liquid crystal screen and a backlight module arranged on the incident surface of the transparent liquid crystal screen, the backlight module comprises a transparent light guide plate and a dimming film parallel to the transparent light guide plate. The dimming film is in full-fit connectionwith the dot surface of the transparent light guide plate; the transparent liquid crystal screen is completely attached to the light-emitting surface of the transparent light guide plate; a light source is arranged on the edge of the transparent light guide plate, a plurality of transparent liquid crystal screens are sequentially and completely attached to the same transparent light guide plate,the dimming film comprises a white dimming film and a black dimming film, the rough surface of the white dimming film is completely attached to the mirror surface of the black dimming film, and the mirror surface of the white dimming film is completely attached to the dot surface of the transparent light guide plate. According to the display device at any time, transparent and non-transparent display of the display device can be switched at any time, and screen information can be displayed more clearly.

Description

technical field

[0001] The invention relates to the technical field of transparent display, in particular to a transparent display device. Background technique

[0002] A transparent display means that the display itself has a certain degree of light penetration, allowing users to clearly see the background behind the display while watching the display screen. Therefore, transparent displays are suitable for application in building windows, high-speed trains, subways, and shop windows.

[0003] However, in the prior art, transparent display and non-transparent display are realized by two independent devices, and it is difficult to switch between transparent and non-transparent display at any time through the same device, and the image quality of the existing transparent display is very rough, and Transparent display costs are relatively high. Contents of the invention

[0004] Based on the technical problems in the background technology, the present invention proposes a ...
