Abstract
A head-mounted display (HMD) presents viewable media to a user. The HMD includes a light source and an optical block. The light source includes a first sub-pixel mounted on a first set of microbumps at a first height from a substrate and emits light within a first optical band, and a second sub-pixel mounted on a second set of microbumps at a second height from the substrate that is different from the first height, and emits light over a second optical band that is different than the first optical band. The optical block receives the image light from the light source, and directs the image light to an eyebox, wherein the first height and the second height mitigates longitudinal chromatic aberration and field curvature in the optical block.
