A transparent display device

Abstract

The invention discloses a transparent display device, comprising: a transparent display panel, a first optical structure fixed on the light incident side of the transparent display panel, and a plurality of light sources arranged on the side of the first optical structure; wherein, the first optical structure On the side away from the transparent display panel, there are a plurality of uniformly arranged convex structures connected to the first optical structure, and the refractive index of the medium between the first optical structure and the transparent display panel is smaller than that of the first optical structure. Due to the evenly distributed convex structure, the light incident on the surface of the first optical structure close to the transparent display panel by the light source, the light with an incident angle smaller than the critical angle of total reflection passes through the first optical structure and shoots to the transparent display structure, as The transparent display structure provides a backlight source, and the light with an incident angle greater than or equal to the critical angle of total reflection can be emitted through the convex structure to provide a light source for the display object, thereby realizing a double-sided open transparent display effect and improving the performance of the transparent display device. flexibility.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent display device. Background technique [0002] With the development of display technology, various new technologies are constantly emerging, and transparent display technology has attracted more and more attention because of its transparent display panel and its unique applications. [0003] A transparent display generally refers to a display that can form a transparent display state so that the viewer can see the image displayed on the display and the image behind the display. Transparent displays have many possible applications, such as windows in buildings or cars and display windows in shopping malls. In addition to these large device applications, small devices such as handheld tablets can also benefit from transparent displays, for example, enabling users to view maps and see through the screen to what is ahead. [0004] In the liquid crystal display (Liquid...
