Flexible displays for VR/AR headsets

1. A headset for virtual reality imaging, comprising:

a first display configured to generate multiple light beams from a central portion of a field of view in an image provided to a user;

a first optical element configured to provide the light beams forming a central portion of the field of view through an eyebox of the headset that limits a volume including a pupil of the user; and

a second display configured to provide a peripheral portion of the field of view for the image through the eyebox, wherein the second display includes multiple light emitting pixels arranged in a two-dimensional surface, wherein the central portion and the peripheral portion of the field of view comprise at least one half steradian of a field of view of a user of the headset.

2. The headset of claim 1 , wherein the peripheral portion of the field of view has a higher angular resolution of fifteen arcminutes in an area adjacent to the central portion of the field of view.

3. The headset of claim 1 , wherein the second display provides an angular resolution that is axially decaying in the peripheral portion of the field of view.

4. The headset of claim 1 , wherein the two-dimensional surface is a conical surface that wraps around the first optical element.

5. The headset of claim 1 , further comprising a multi-lenslet array that conforms to the two-dimensional surface and is configured to provide multiple light beams from the second display through the eyebox.

6. The headset of claim 1 , wherein the two-dimensional surface follows a one-dimensional curvature that conforms to a temple of a user of the headset.

7. The headset of claim 1 , wherein the second display includes one of a flexible organic light emitting diode array, a flexible liquid crystal display, or a light emitting diode array.

8. The headset of claim 1 , wherein the second display includes multiple portions of active pixels that provide a reduced angular resolution along a direction in the two- dimensional surface away from the first optical element.

9. The headset of claim 1 , wherein the two-dimensional surface of the second display is oriented to avoid a reflected light ray from the second display to pass through the eyebox.

10. A display for a headset, comprising:

a pixel array configured in a two-dimensional surface wherein a first dimension is substantially perpendicular to a central display providing a central portion of a field of view of an image to a user of the headset;

a memory that stores multiple instructions; and

one or more processors configured to execute the instructions to activate each of multiple segments in the pixel array to emit light beams forming a peripheral field of view of the image, each segment providing a diminishing angular resolution of the image along the first dimension, wherein the image is projected on a retina of a user of a headset through an eyebox delimiting a position of a pupil of the user, wherein the central portion of the field of view and the peripheral field of view comprises at least one steradian of a user's field of view at a resolution of at least fifteen arcminutes.

11. The display of claim 10 , wherein the instructions further cause the one or more processors to select a portion of the peripheral field of view to each of two adjacent segments to form a continuous image in the retina of the user, through the eyebox.

12. The display of claim 10 , wherein a gap of inactive pixels between two adjacent segments is selected so that the light beams provided by each of two adjacent segments in the pixel array forms a continuous, no-crosstalk image in the retina of the user, through the eyebox.

13. The display of claim 10 , wherein the instructions further include an instruction indicative of a position of the pupil of the user within the eyebox.

14. The display of claim 10 , further comprising a sensor configured to provide a location information for the pupil of the user within the eyebox.

15. The display of claim 10 , wherein the memory includes calibration instructions to select the peripheral field of view of the image and to modify an angular mapping of the pixel array into a retina of the user, based on a gaze direction of the user and the position of the pupil.

16. A method, comprising:

capturing, with a camera, an image of a two-dimensional display for a headset, the image associated with a peripheral field of view of a user of the headset, and the two- dimensional display including a first dimension substantially perpendicular to a central display that provides a central portion of a field of view to the user of the headset;

obtaining an angular resolution map from the image of the two-dimensional display, wherein the angular resolution map includes an angular distance in the image between two adjacent points in the two-dimensional display; and

verifying that the angular resolution map includes a curve above a pre-selected threshold along the first dimension.

17. The method of claim 16 , further comprising activating a segment of the two-dimensional display to improve the angular resolution map.

18. The method of claim 16 , further comprising determining a correction factor to improve the angular resolution map based on a pixel resolution of the two-dimensional display and a pupil position of the user of the headset, and storing the correction factor in a memory of the headset.
