Embodiment Construction

[0014] As noted above, certain embodiments of the present technology relate to apparatus, methods, and systems for mitigating ghost images in a see-through mixed reality display device system including a display engine and an optical waveguide.

[0015] In the following description, the same numerals or reference signs will be used to refer to the same parts or elements throughout. In addition, the first digit of a three-digit reference number identifies the drawing in which the reference number first appears.

[0016] Figure 1A , Figure 1B and Figure 1C Front, top, and side views, respectively, of an exemplary optical waveguide 102 that may be used to replicate an image associated with an input pupil to an expanded output pupil. As used herein in discussing waveguides, the term "input pupil" refers to the aperture through which light corresponding to an image is overlaid on the input coupler of the waveguide. As used herein in discussing waveguides, the term "output pup...

Abstract

The non -far -hearted display system of heavy shadow images includes optical waveguide and display engine.The image former of the display engine includes the reflection surface, which has the surface of the reflection surface.The lighting engine of the display engine transmits light towards the reflection surface of the image formor, so that the main light and the surface method line of the main light and the surface of the reflection surface shift sharply.The display engine reflects the reflected surface of the image formor, and the light corresponding to the image is guided by the input coupling of the optical waveguide to the input coupling of the optical waveguide to combine the optocoupler corresponding to the image and enter it.Output coupler.Because the main light of the light emitted from the lighting engine to the surface method of the surface of the reflection surface is shifted, the heavy shadow image is at least partially prevented.

Description

Background technique [0001] Various types of computing, entertainment, and / or mobile devices can be implemented with transparent or translucent displays through which a user of the device can view the surrounding environment. Such devices may be referred to as see-through mixed reality display device systems or augmented reality (AR) systems that enable users to see through the device's transparent or translucent display to view the surrounding environment and also view images of virtual objects (e.g., text, graphics, video, etc.), these virtual objects are generated for display to appear as part of and / or overlaid on the surrounding environment. These devices, which may be implemented as, but are not limited to, head-mounted display (HMD) glasses or other wearable display devices, typically utilize optical waveguides to replicate the image produced by the display engine to a location where the device Users of the can view the image as a virtual image in an augmented reality ...
