Stacked display panels for image enhancement
First Claim
1. An electronic display comprising:
- a plurality of display panels that output image light, the plurality of display panels including a first display panel and a second display panel, wherein a first plurality of sub-pixels of the first display panel are configured to operate over a first range of luminosities, and a second plurality of sub-pixels of the second display panel are configured to operate over a second range of luminosities that is higher than the first range of luminosities;
wherein the electronic display is configured to;
divide a dynamic range of an image into multiple reduced dynamic ranges, wherein each reduced dynamic range corresponds to a different range of luminosities over which different display panels are configured to operate;
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 of the multiple reduced dynamic ranges; and
display, by the second display panel, a second portion of the image in accordance with the second range of luminosities and a second reduced dynamic range of the multiple reduced dynamic ranges.

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.
