INTEGRATED DISPLAY AND PHOTOSENSOR
First Claim
1. An apparatus for simultaneously imaging a subject and displaying computer generated image (“
- CGI”
) light to the subject, the apparatus comprising;
a display array disposed on a semiconductor die, wherein the display array includes display pixels configured to selectively generate the CGI light to be sent along a forward optical path;
a photodetector array disposed on the semiconductor die and positioned to receive non-visible image light directed along a reverse optical path, wherein the nonvisible image light is reflected by the subject and travels along the reverse optical path in a substantially opposite direction as the CGI light to be sent along the forward optical path; and
a filter element disposed in the reverse optical path for substantially filtering out visible light and substantially passing the non-visible image light to the photodetector array.

Abstract
An apparatus for simultaneously imaging a subject and displaying computer generated image (“CGI”) light to the subject includes a display array and a photodetector array. The display array and the photodetector array are disposed on a same semiconductor die. The display array includes display pixels configured to selectively generate the CGI light to be sent along a forward optical path. The photodetector array is positioned to receive non-visible image light that is reflected by the subject and directed along a reverse optical path. The CGI light to be sent along the forward optical path travels in a substantially opposite direction as the non-visible image light directed along the reverse optical path.

11. An apparatus for a head mounted display (“
- HMD”
), the apparatus comprising;a first light source for providing illumination light; a Liquid Crystal on Silicon (“
LCOS”
) array disposed on a semiconductor die, wherein LCOS pixels of the LCOS array are configured to selectively reflect the illumination light provided by the first light source to generate computer generated image (“
CGI”
) light to be sent along a forward optical path within an eyepiece;a second light source oriented to emit non-visible light in an eyeward direction of the HMD; and a photodetector array disposed on the semiconductor die and positioned to receive a reflection of the non-visible light emitted in the eyeward direction, the reflection directed along a reverse optical path in the eyepiece in a substantially opposite direction as the CGI light along the forward optical path. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of operating a head mounted display (“
- HMD”
), the method comprising;acquiring view data corresponding to a field of view of a user of the HMD; receiving non-visible light reflected off of an eye of the user of the HMD to generate eye image data; determining a visual point of interest of the user based on the view data and the eye image data; and projecting refreshed computer generated image (“
CGI”
) light from a Liquid Crystal on Silicon (“
LCOS”
) array onto the eye of the user based on the visual point of interest, wherein a photodetector array receives the non-visible light and the photodetector array and the LCOS array are both disposed on a same semiconductor die. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
