Problems solved by technology
Although a reflective film can be formed on the surface of the optical waveguide element, so that the light that does not satisfy the total reflection condition can continue to propagate in the optical waveguide element through the reflection of the reflective film, so as to prevent the light from exiting the optical waveguide element from affecting the display effect, but this will As a result, the light in the optical waveguide component can only exit in the area without a reflective film to form a display image, which greatly limits the exit range of the light

Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0034] As in the background art, most of the current optical waveguide components use the principle of total reflection to transmit light. Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an optical waveguide element that uses the principle of total reflection to propagate light. The incident light is reflected into the optical waveguide medium 10 by the reflective film 11, so that the reflection angle of the incident light on the surface of the optical w...

The embodiment of the invention provides an optical waveguide device, a display device and display equipment. The optical waveguide device comprises an optical waveguide dielectric body, a first polarization reflection layer and an optical structure layer; the optical waveguide dielectric body comprises a first surface and a second surface which are opposite, the first polarization reflection layer is arranged on the first surface, and the optical structure layer is arranged on the second surface; the optical waveguide dielectric body is used for transmitting light, and the light comprises first polarized light; the first polarization reflection layer is used for reflecting the first polarized light and transmitting the second polarized light; the optical structure layer is used for converting the first polarized light incident at a preset angle into second polarized light, reflecting the second polarized light to the first polarization reflection layer, and reflecting the first polarized light incident at other angles to the first polarization reflection layer. The emergent area of the second polarized light is not limited in the area without the reflecting film layer any more, so that the light emergent range of the optical waveguide device is enlarged.
Description
technical field [0001] The embodiments of the present application relate to the field of optical display technology, and in particular to an optical waveguide device, a display device, and a display device. Background technique [0002] An optical waveguide is a dielectric device that guides light waves to propagate in it, also known as a dielectric optical waveguide. Optical waveguides have become an important component of near-eye display devices due to their thinness and lightness. However, most of the current optical waveguide components use the principle of total reflection to propagate light. Although a reflective film can be formed on the surface of the optical waveguide element, so that the light that does not satisfy the total reflection condition can continue to propagate in the optical waveguide element through the reflection of the reflective film, so as to prevent the light from exiting the optical waveguide element from affecting the display effect, but this w...
