[0022] See also Figure 1 , the optical display assembly 100 comprises: an optical waveguide layer 110, a first optical adjustment layer 120 and a second optical adjustment layer 130. In some embodiments, the optical waveguide layer is used to couple out the waveguide output light for displaying the virtual image. In some embodiments, the first optical adjustment layer is configured such that the waveguide output light undergoes a first deflection after passing through the first optical adjustment layer. In some embodiments, the deflection causes the imaging position of the virtual image to be adjusted toward a predetermined display distance. In some embodiments, the predetermined display distance matches the physical distance of a real object. For example, the predetermined display distance is the physical distance of a real object. In some embodiments, by adjusting the imaging position of the virtual image, the convergence adjustment conflict when the user uses the optical display assembly can be reduced. In some embodiments, by adjusting the imaging position of the virtual image to match the physical distance of the real object, the focal length of the user's eyes and the line of sight distance are matched, thereby reducing the convergence adjustment conflict when the user uses the optical display assembly.

[0023] In some embodiments, the second optical adjustment layer is configured such that an external incident light representing a real object undergoes a second deflection when passing through the second optical adjustment layer, and the second deflection is restored when passing through the optical waveguide layer and the first optical adjustment layer.

[0024] In some embodiments, the external incident light is deflected by the second optical adjustment layer and then restored by the first optical adjustment layer, and the external incident light entering the user's eyes is not deflected. Therefore, the optical display component does not change the light of the external real object, but only deflects the light emitted by the waveguide.

[0025] In some embodiments, the first optical adjustment layer is disposed on a first side of the optical waveguide layer. In some embodiments, the first optical adjustment layer is disposed on a second side of the optical waveguide layer. In some embodiments, the first side of the optical waveguide layer is, for example, a side close to the user's eyes or a side away from a real object. In some embodiments, the second side of the optical waveguide layer is, for example, a side away from the user's eyes or a side close to a real object.

[0026] In some embodiments, the ability of the first optical adjustment layer or the second optical adjustment layer to deflect light can be characterized by a deflection parameter.

In some embodiments, controlling the deflection parameter of the first optical adjustment layer to the first target deflection parameter causes the light emitted from the waveguide to undergo a first deflection through the first optical adjustment layer.

[0029] In some embodiments, the refraction parameter of the second optical adjustment layer is adjustable. In some embodiments, the refraction parameter of the second optical adjustment layer is adjusted to change the refraction capability of the second optical adjustment layer to external incident light. In some embodiments, (the controller) changes the refraction capability of the second optical adjustment layer to external incident light by adjusting the refractive index of the second optical adjustment layer. In other embodiments, (the controller) changes the refraction capability of the second optical adjustment layer to external incident light by adjusting the focal length and / or prismatic power of the second optical adjustment layer.

[0030] In some embodiments, the controller is configured to: control the deflection parameter of the second optical adjustment layer to a second target deflection parameter, control the deflection parameter of the second optical adjustment layer to the second target deflection parameter so that an external incident light representing a real object undergoes a second deflection through the second optical adjustment layer, and restores the second deflection through the optical waveguide layer and the first optical adjustment layer.

[0031] In some embodiments, the refraction parameters of the second optical adjustment layer can be determined based on the refraction parameters of the first optical adjustment layer. In some embodiments, the light deflection caused by the refraction parameters of the second optical adjustment layer is opposite to the light deflection caused by the refraction parameters of the first optical adjustment layer.

[0032] In some embodiments, the first optical adjustment layer or the second optical adjustment layer is, for example, an optical layer such as a liquid crystal optical device, a micro-lens array optical device, a combination of a prism and / or a lens.

In some embodiments, the (controller) adjusts the refractive index of the first optical adjustment element to adjust the imaging position of the virtual image. In other embodiments, the (controller) adjusts the optical focal length and / or prism power of the first optical adjustment element to adjust the imaging position of the virtual image.

In some embodiments, controlling the deflection parameter of the first optical adjustment element to the first target deflection parameter causes the light emitted from the waveguide to undergo a first deflection through the first optical adjustment element.

[0050] In some embodiments, the deflection parameter of the second optical adjustment element is adjustable. In some embodiments, the deflection parameter of the second optical adjustment element is adjusted to change the deflection capability of the second optical adjustment element to external incident light. In some embodiments, the (controller) changes the deflection capability of the second optical adjustment element to external incident light by adjusting the refractive index of the second optical adjustment element. In other embodiments, the (controller) changes the deflection capability of the second optical adjustment element to external incident light by adjusting the optical focal length and / or prism power of the second optical adjustment element.
