Abstract

A display device is mounted on and/or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

First claim

What is claimed is:

1. An eye mounted display system comprising:
an intraocular display capsule configured to be placed inside a user's eye; and
a femto projector contained in the intraocular display capsule, the femto projector projecting a plurality of pixels onto a retina of the user's eye, thereby forming a visual sensation of an image comprising the pixels, the femto projector comprising:
an array of addressable display pixels, and
display optics projecting light from the display pixels to a portion of the retina corresponding to the image displayed by the femto projector, where the portion of the retina is fixed as the user's eye rotates in its socket and thereby forming the visual sensation of the image comprising the pixels.

2. The eye mounted display system of claim 1 where the intraocular display capsule is configured to be placed within an anterior chamber of the user's eye between a cornea and a lens of the user's eye.

3. The eye mounted display system of claim 1 where the intraocular display capsule is configured to be placed on a front surface of a lens of the user's eye.

4. The eye mounted display system of claim 1 where the intraocular display capsule is configured to be placed inside a lens of the user's eye.

5. The eye mounted display system of claim 1 where the intraocular display capsule is configured to replace a lens of the user's eye.

6. The eye mounted display system of claim 1 where the intraocular display capsule is configured to be placed on a rear surface of a lens of the user's eye.

7. The eye mounted display system of claim 1 where the projected pixels having different sizes at the retina.

8. The eye mounted display system of claim 7 where the sizes of the projected pixels at the retina vary in part as a function of a size of retinal receptive fields at the retina.

9. The eye mounted display system of claim 7 where the pixels projected to a center of a fovea of the eye have a smallest size among all the projected pixels.

10. The eye mounted display system of claim 1 where the sizes of the projected pixels at the retina have a resolution that is at least as high as a native resolution of the eye.

11. The eye mounted display system of claim 1 where the array of addressable display pixels include display pixels of different colors, whereby the femto projector projects a color image onto the retina.

12. The eye mounted display system of claim 1 where the femto projector comprises a plurality of sub-displays, each sub-display comprising:
a plurality of display pixels displaying a different portion of the image for each sub-display, and
display optics projecting light from the display pixels to a portion of the retina corresponding to the portion of the image displayed by that sub-display, different sub-displays projecting light to different portions of the retina, and the sub-displays in aggregate projecting light to portions of the retina that in aggregate form the image displayed by the femto projector.

13. The eye mounted display system of claim 1 where the array of addressable display pixels is a hexagonal array.

14. The eye mounted display system of claim 1 further comprising:
a logic chip coupled to an LED chip, the LED chip containing the array of addressable display pixels, the logic chip receiving data specifying the pixels projected by the femto projector and producing analog drive signals for the LED chip.

15. The eye mounted display system of claim 1 further comprising:
a data receiver device contained in the intraocular display capsule for wirelessly receiving data that specifies the pixels projected by the femto projector.

16. The eye mounted display system of claim 1 further comprising:
a power receiver device contained in the intraocular display capsule that wirelessly receives power for the femto projector.

17. The eye mounted display system of claim 1 further comprising:
an accelerometer contained in the intraocular display capsule for measuring movement of the eye.

18. The eye mounted display system of claim 1 further comprising:
a device contained in the intraocular display capsule for wirelessly receiving data and/or power for the femto projector using a water penetrating, mid-infrared frequency.

19. The eye mounted display system of claim 1 further comprising an eye tracker that tracks an orientation and/or position of the eye, where the image projected by the femto projector is a function of the orientation and/or position of the eye.

20. The eye mounted display system of claim 1 further comprising a controller chip that transmits to the femto projector data specifying the pixels projected by the femto projector.
