Curved narrowband illuminant display for head mounted display

1. A head mounted display, comprising:

a first lens having a first curvature;

a curved display upon which the first lens is focused, the display having a curvature such that the field curvature of the first lens is corrected by the curvature of the display;

a processor operable with the first lens to:

receive a planar image from an image generation device;

determine an red undistorted image, from the planar image, for the color red;

determine an green undistorted image, from the planar image, for the color green;

determine an blue undistorted image, from the planar image, for the color blue; and

generate an undistorted image from the red undistorted image, the green undistorted image, and the blue undistorted image to correct chromatic aberration associated with the first lens, wherein the processor generates the undistorted image for projection on the curved display to correct chromatic aberration.

2. The head mounted display of claim 1 , wherein the curved display further comprises:

a flat display; and

a fiber optic bundle placed on the flat display on a first surface and a curved profile ground into a second surface opposite the first surface.

3. The head mounted display of claim 2 , wherein the curved display is a transmissive display having a backlight mounted behind the curved display.

4. The head mounted display of claim 3 , wherein the backlight only puts out a narrow band of the light in each of red, green, and blue lights mounted within the backlight.

5. The head mounted display of claim 4 , wherein the narrow band of light is less than or equal to five nm of bandwidth for each of the red, green, and blue lights.

6. The head mounted display of claim 2 wherein the curved display is an emissive display.

7. The head mounted display of claim 6 , further comprising a color filter mounted on the emissive display so as to limit the band of the wavelengths of the red, green, and blue light.

8. The head mounted display of claim 6 , further comprising quantum dots on the emissive display so as to limit the band of the wavelengths of the red, green, and blue light.

9. A head mounted display, comprising:

a first lens having a first curvature;

a display upon which the first lens is focused; and

a coherent fiber optic bundle sheet mounted on the display, wherein the coherent fiber optic bundle sheet has a curvature such that the field curvature of the first lens is corrected by the curvature of the coherent fiber optic bundle sheet; and

a processor operable, with the first lens, to correct chromatic aberration associated with the first lens, wherein the display has a backlight mounted behind the display, wherein the backlight only puts out a narrow band of the light in each of red, green, and blue lights mounted within the backlight, and wherein the narrow band of light is less than or equal to five nm of bandwidth for each of the red, green, and blue lights, wherein the processor is operable to:

receive a planar image from an image generation device;

determine an red undistorted image, from the planar image, for the color red;

determine an green undistorted image, from the planar image, for the color green;

determine an blue undistorted image, from the planar image, for the color blue; and

generate a total image from the red undistorted image, the green undistorted image, and the blue undistorted image to correct the chromatic aberration associated with the first lens.

10. The head mounted display of claim 9 , wherein the coherent fiber optic bundle sheet is affixed to the display.

11. The head mounted display of claim 10 , wherein the display is a flat display.

12. The head mounted display of claim 11 , wherein the display is transmissive or emissive.

13. The head mounted display of claim 12 , wherein the red, green, and blue undistorted images are generated for display and combined into the total image for display.

14. The head mounted display of claim 10 , wherein the display is an emissive display.

15. The head mounted display of claim 14 , further comprising a color filter mounted on the emissive display so as to limit the band of the wavelengths of the red, green, and blue light.

16. The head mounted display of claim 14 , further comprising quantum dots on the emissive display so as to limit the band of the wavelengths of the red, green, and blue light.

17. A method of correcting chromatic aberration in a display, comprising:

receiving a planar image;

computing a red undistorted image, from the planar image, for the color red;

computing a green undistorted image, from the planar image, for the color green;

computing a blue undistorted image, from the planar image, for the color blue;

combining the undistorted red, green, and blue undistorted images into a total image; and

displaying the total image on a display of a head-mounted display (HMD) to correct chromatic aberration between the display and a lens of the HMD.

18. The method of claim 17 , further comprising providing a display with narrowband red, green, and blue light sources to illuminate the undistorted red, green, and blue images.

19. The method of claim 17 wherein generating undistorted red, green, and blue images comprises:

generating and displaying a red, green, and blue test pattern;

measuring the pixel shift of each pixel of the red, green, and blue test pattern; and

shifting the red, green, and blue images based on the measured pixel shift.

20. The method of claim 17 further comprising providing a display with narrowband red, green, and blue emissive light that projects the undistorted red, green, and blue images.
