Abstract
A head mounted display (HMD) includes an electronic display, a microlens array, and an optics block. The electronic display is composed of a plurality of sub-pixels, and each sub-pixel is configured to emit image light according to respective emission distribution. The microlens array is coupled to the electronic display and includes a plurality of microlenses. The microlens array concentrates the emission distributions of the sub-pixels to form concentrated image light and directs the concentrated image light towards a target region. The optics block is positioned in the target region. The optics block is configured to direct the concentrated image light from the microlens array to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.
