Abstract

A head-mounted display (HMD) includes an electronic display element and an optics block. The electronic display element includes a plurality of display panels that together output image light. The plurality of panels including a first display panel and a second display panel. The first display panel includes a first plurality of sub-pixels that are separated from each other by a non-emission area. The second panel includes a second plurality of sub-pixels. The second display panel is positioned offset from the first display panel such that the second plurality of sub-pixels emit light through the non-emission area of the first display panel. The optics block configured to direct the image light to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.

Claims

4-1. The HMD of claim 1, wherein the first display panel and the second display panel are partially transparent to visible light.

13. A head-mounted display (HMD) comprising:

an electronic display element comprising a plurality of display panels that together output image light, the plurality of panels including a first display panel and a second display panel, the first display panel including a first plurality of sub-pixels, the first plurality of sub-pixels separated from each other by a non-emission area, the second panel including a second plurality of sub-pixels, the second display panel positioned offset from the first display panel such that the second plurality of sub-pixels emit light through the non-emission area of the first display panel; and

an optics block configured to;

magnify the image light; and

direct the image light to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.

14. The HMD of claim 13, wherein the first plurality of sub-pixels are configured to operate over a first range of luminosities, and the second plurality of sub-pixels are configured to operate over a second range of luminosities that is higher than the first range of luminosities, and the electronic display element is configured to:

receive an image having a dynamic range;

divide the dynamic range into ‘

n’

number of reduced dynamic ranges, wherein ‘

n’

is a number of display panels;

provide each display panel a respective reduced dynamic range;

display, by the first display panel, a first portion of the image in accordance with the first range of luminosities and a first reduced dynamic range; and

display, by the second display panel, a second portion of image in accordance with the second range of luminosities and a second reduced dynamic range.

15. The HMD of claim 14, wherein the electronic display panel further comprises a third display panel, the third panel including a third plurality of sub-pixels, the third display panel positioned offset from the first display panel and the second display panel such that the third plurality of sub-pixels emit light through the non-emission area of the first display panel and the non-emission area of the second display panel, and the third plurality of sub-pixels operate over a third range of luminosities that is higher than the second range of luminosities, and the electronic display element is configured to:

display, by the third display panel, a third portion of the image in accordance with the third range of luminosities and the third reduced dynamic range.

18. The HMD of claim 13, wherein the second plurality of sub-pixels are configured to emit light at a higher brightness than the first plurality of sub-pixels, and a difference in the brightness between the second plurality of sub-pixels and the first plurality of sub-pixels offsets attenuation of the light emitted from the second plurality of sub-pixels resulting from passing through the first display element.

19. The HMD of claim 13, wherein the electronic display panel further comprises an intermediate component, the intermediate component positioned between the first display panel and the second display panel such that light emitted from the second display panel passes through the intermediate component before passing through the first display panel.

20. A head-mounted display (HMD) comprising:

an electronic display element comprising a plurality of display panels that together output image light, the plurality of panels including a first display panel and a second display panel, the first display panel including a first plurality of sub-pixels, the first plurality of sub-pixels separated from each other by a non-emission area, the second panel including a second plurality of sub-pixels, the second display panel positioned offset from the first display panel such that the second plurality of sub-pixels emit light through the non-emission area of the first display panel; and

an optics block configured to;

correct one or more optical aberrations in the image light;

magnify the image light; and

direct the image light to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.
