Abstract

The invention discloses a transparent display device, relating to the field of display, and capable of improving transmittance of the transparent display device. The transparent display device comprises an upper substrate, a lower substrate and a colour H-PDLC (holographic polymerdispersed liquid crystal) layer, wherein the upper substrate sequentially comprises a transparent electrode and an alignment film from top to bottom, the lower substrate sequentially comprises the transparent electrode and the alignment film from top to bottom, and the colour H-PDLC layer is arranged between the upper substrate and the lower substrate.

Description

technical field [0001] The invention relates to the display field, in particular to a transparent display device. Background technique [0002] With the development of display technology and the increasing demand for the use of portable information media, in recent years, so-called transparent display devices have been actively researched and developed. Objects behind the display can be seen through the display when no voltage is applied. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] In the existing transparent display device structure, the liquid crystal molecules are located between two polarizers, and the electric field is used to control the rotation of the liquid crystal molecules to change the polarization direction of light, and cooperate with the polarizers to form different gray levels. However, the use of polarizers greatly reduces the transmittance of the t...
