Head mounted viewer for AR and VR scenes

1. An optical device comprising:

a viewing region including an image display layer and a variable lens layer,

wherein the image display layer includes:

a plurality of variable transparency pixels that are disposed in a two-dimensional arrangement and that are individually selectably operable to vary transparency to passage of ambient light therethrough, and

a plurality of display pixels that are disposed in a two-dimensional arrangement and that are individually selectably operable to emit light, and

wherein the variable lens layer includes

a plurality of variable lens pixels that are disposed in a two-dimensional arrangement and that are individually operable to impart a variable index of refraction to light incident thereupon; and

wherein the image display layer and the variable lens layer are disposed such that ambient light may pass between the variable transparency pixels and the variable lens pixels and such that light may pass between the display pixels and variable lens pixels.

2. The optical device of claim 1 further including:

a control circuit and a non-transitory computer readable medium operably coupled thereto, the non-transitory computer readable medium comprising a plurality of instructions stored in association therewith that are accessible to, and executable by, the control circuit, where the plurality of instructions comprises:

display instructions that, when executed, cause a plurality of display pixels within a local display region within the image display layer to emit light representing an image; and

index of refraction instructions that, when executed, select individual indexes of refraction for individual lens pixels of a plurality of lens pixels within a local lens region, to impart to light incident thereupon, emitted by one or more of the display pixels within the local display region.

3. The optical device of claim 2 further including:

a sensor to select the focal plane for the light representing the image.

4. The optical device of claim 2 ,

wherein the display instructions, when executed, cause a plurality of display pixels within a local display region within the image display layer to emit light representing a three-dimensional image; and

wherein the index of refraction instructions, when executed, select individual indexes of refraction for the individual lens pixels of the plurality of pixels within the local lens region, to impart to light incident thereupon, emitted by one or more of the display pixels within the local display region to cause the image to have a three-dimensional appearance at the focal plane.

5. The optical device of claim 2 further including:

transparency instructions that, when executed, cause a plurality of variable transparency pixels inside the local display region to operate at a partially transparent level.

6. The optical device of claim 5 ,

wherein the transparency instructions, when executed, cause a plurality of variable transparency pixels inside and outside the local display region to operate at a partially transparent level.

7. The optical device of claim 2 further including:

transparency instructions that, when executed, cause a plurality of variable transparency pixels inside the local display region to operate at a transparency level different from variable transparency pixels outside the local display region.

8. The optical device of claim 2 further including:

non-transparency instructions that, when executed, cause a plurality of variable transparency pixels inside the local display region to operate at a non-transparent level.

9. The optical device of claim 8 ,

wherein the non-transparency instructions, when executed, cause a plurality of variable transparency pixels inside and outside the local display region to operate at a non-transparent level.

10. The optical device of claim 1 ,

wherein the index of refraction instructions, when executed, can select individual indices of refraction for first and second lens pixels within the variable lens layer such that the index of refraction selected for the first lens pixel is at least five percent greater than the index of refraction selected for the second lens pixels.

11. The optical device of claim 1 ,

wherein the transparency instructions, when executed, can select individual partial transparency levels for first and second variable transparency pixels within the variable lens layer such that the transparency level selected for the first variable transparency pixel is at least five percent greater than the transparency level selected for the second variable transparency pixels.

12. The optical device of claim 1 further including:

a control circuit and a non-transitory computer readable medium operably coupled thereto, the non-transitory computer readable medium comprising a plurality of instructions stored in association therewith that are accessible to, and executable by, the control circuit, where the plurality of instructions comprises:

display instructions that, when executed, cause a plurality of display pixels within a local display region within the image display layer to emit light representing an image;

index of refraction instructions that, when executed, select individual indexes of refraction for individual lens pixels of a plurality of lens pixels within a local lens region, to impart to light incident thereupon, emitted by one or more of the display pixels within the local display region, to focus the image at a focal plane; and

transparency instructions that, when executed, cause a plurality of variable transparency pixels inside the local display region to operate at a transparency level different from variable transparency pixels outside the local display region.

13. The optical device of claim 1 ,

wherein the plurality of variable transparency pixels includes at least one of variable transparency liquid crystal display (LCD) devices or organic light-emitting diode (OLED) devices.

14. The optical device of claim 1 ,

wherein the plurality of display pixels includes at least one of electroluminescent (EL) devices, vacuum fluorescent devices, plasma display panel devices, LCD devices, thin film transistor (TFT) LCD devices, OLED devices and Liquid Crystal on Silicon (LCoS) devices.
