The keeper's note

Increasing returned light in compact AR/VR display.

Abstract

Implementations of an augmented reality (AR)-capable display device for displaying polarized light generated by a display onto a predefined field of view are disclosed herein. The display device comprises an optical arrangement having a predefined arrangement relative to a predefined position of the display and defining the field of view. The optical arrangement comprises a mirror element disposed within the field of view and at least partially transmissive of ambient light incident on a first surface and at least partially reflective of light incident on an opposite second surface, a polarized beam splitter element disposed within the field of view and closer to the second surface of the mirror element than the first surface, a half-wave plate element disposed between the polarized beam splitter element and the display and outside the field of view, and a quarter-wave plate element disposed between the polarized beam splitter element and the mirror element.

Background

BACKGROUND(1) Field of the Disclosure(2) The present disclosure generally relates to computer-based entertainment, and more specifically to optical arrangements suitable for augmented reality (AR) and/or virtual reality (VR) devices.(3) Description of the Related Art(4) Computer graphics technology has significantly progressed since the first video games were developed. Relatively inexpensive 3D graphics engines now provide nearly photo-realistic interactive game play on hand-held video game, home video game, and personal computer hardware platforms costing only a few hundred dollars. These video game systems typically include a hand-held controller, game controller, or, in the case of a hand-held video game platform, an integrated controller. A user interacts with the controller to send commands or other instructions to the video game system to control a video game or other simulation. For example, the controller may include a joystick and buttons operated by the user.(5) While video games allow the user to interact directly with the video game system, such interactions primarily influence the graphical depiction shown on the video game device (or on a connected display), and rarely influence any other objects outside of the virtual world. That is, a user may specify an input to the video game system, indicating that the user's avatar should perform a jump action, and in response the video game system could display the user's avatar jumping. However, such interactions are ty

Claims

1. An augmented reality (AR)-capable display device comprising: a display configured to generate polarized light; one or more computer processors configured to: receive display data; and generate compensated display data for the display based on identification information indicating one or both of a brand and a model of the display; and an optical arrangement having a predefined arrangement relative to a predefined position of the display and defining a field of view, the optical arrangement comprising: a mirror element having a first surface and opposite second surface, the mirror element disposed within the field of view and being at least partially transmissive of ambient light incident on the first surface and at least partially reflective of light incident on the second surface; a polarized beam splitter element disposed within the field of view and closer to the second surface of the mirror element than the first surface; a half-wave plate element disposed between the polarized beam splitter element and the display and outside the field of view; and a quarter-wave plate element disposed between the polarized beam splitter element and the mirror element, wherein the optical arrangement defines a first optical path from the display, through the half-wave plate element, to the polarized beam splitter element, through the quarter-wave plate element, to the second surface of the mirror element, through the quarter-wave plate element and through the polarized beam splitter element, and wherein the optical arrangement further defines a second optical path from the first surface of the mirror element through the quarter-wave plate element and through the polarized beam splitter element. 8. A system comprising: a mobile computing device comprising: a display configured to generate polarized light, wherein the mobile computing device is configured to generate compensated display data for the display based on identification information indicating at least one of: a brand of the display, a model of the display, a brand of the mobile computing device, and a model of the mobile computing device; and an optical arrangement having a predefined arrangement relative to a predefined position of the display and defining a field of view, the optical arrangement comprising: a mirror element having a first surface and opposite second surface, the mirror element disposed within the field of view and being at least partially transmissive of ambient light incident on the first surface and at least partially reflective of light incident on the second surface; a polarized beam splitter element disposed within the field of view and closer to the second surface of the mirror element than the first surface; a half-wave plate element disposed between the polarized beam splitter element and the display and outside the field of view; and a quarter-wave plate element disposed between the polarized beam splitter element and the mirror element, wherein the optical arrangement defines a first optical path from the display, through the half-wave plate element, to the polarized beam splitter element, through the quarter-wave plate element, to the second surface of the mirror element, through the quarter-wave plate element and through the polarized beam splitter element, and wherein the optical arrangement further defines a second optical path from the first surface of the mirror element through the quarter-wave plate element and through the polarized beam splitter element. 15. An augmented reality (AR)-capable display device comprising: a display configured to generate polarized light with a polarization axis; one or more computer processors configured to: receive display data; and generate compensated display data for the display based on identification information indicating one or both of a brand and a model of the display; and an optical arrangement having a predefined arrangement relative to a predefined position of the display and defining a field of view, the optical arrangement comprising: a polarized beam splitter element disposed within the field of view and having the polarization axis, the polarized beam splitter configured to reflect a first portion of the polarized light; a polarized reflector disposed within the field of view; and a quarter-wave plate element disposed between the polarized beam splitter element and the polarized reflector, the quarter-wave plate element configured to transmit a second portion of the reflected first portion, wherein the polarized reflector is configured to reflect a third portion of the transmitted second portion, wherein the quarter-wave plate element is further configured to transmit a fourth portion of the reflected third portion, and wherein the polarized beam splitter element is further configured to transmit a fifth portion of the transmitted fourth portion.
