Technical Field

Background
Transparent display systems are typically composed of an image source and an imaging window. In existing transparent display systems, there are a variety of options for image sources and imaging windows. The imaging window generally consists of a base material and a reflecting surface, and most of the structures of the imaging window adopt the reflecting surface as an interlayer in the base material, so that the manufacturing process is difficult.
In the prior art, there is a technical solution that uses a source emitting p-polarized light as an image source. For example, imaging with p-polarized light is described in chinese patent applications CN204143067U and CN104267498A, US patent applications US6952312B2, US7123418B2 and US7355796B2, and european patent application EP0836108a 2.
However, when these imaging methods using p-polarized light are applied to a head-up display, a dark spot is formed on the front window, and if a relatively high transmittance is required, the reflectance is reduced, and in order to achieve a good imaging effect, the brightness of the image source is required to be relatively high, thereby increasing the cost of power dissipation of the image source. Therefore, if a relatively high reflectance is required, the transmittance is reduced, and thus the effect of observing the external environment is reduced, resulting in a relatively high demand for brightness of the image source.
In addition, in the prior art, there is also a technique of using a source emitting S-polarized light as an image source, and when the source emitting S-polarized light is used as the image source, a transparent base material is often used for the imaging window, and the transparent base material itself has reflectivity for S-polarized light, so that a ghost image is generated between a virtual image formed by reflecting S-polarized light to human eyes and a virtual image formed by reflecting S-polarized light to human eyes by a reflection surface provided in the base material itself, and the view of an observer is affected.
