摘要： Disclosed are an apparatus and method for increasing the FOV of displayed images in a head-mounted display (HMD) device. A display apparatus comprises a display module and a waveguide optically coupled to the display module. The display module may generate individually multiple different portions of an image, to be conveyed to an optical receptor of a user of the HMD device, and may include multiple optical output ports, each to output a different portion of the image. The waveguide may include multiple optical input ports, each optically coupled to a different one of the optical output ports of the display module, where the waveguide is configured to output, to the optical receptor of the user, light corresponding to the image in its entirety.

摘要： In embodiments of waveguide optics focus elements, an imaging structure includes a waveguide for viewing of an environment that is viewable with the imaging structure. The waveguide transmits light of a virtual image that is generated to appear as part of the environment for augmented-reality imaging or virtual-reality imaging. The imaging structure also includes one or more focus elements that are integrated in the waveguide and switchable to focus the virtual image at a focus depth that approximately correlates to a focal distance of the environment. The focus elements can each be implemented for a different focus depth of the virtual image, and the focus depth is adjustable based on a combination of the focus elements being switched-on or switched-off.
