A display device is mounted on and/or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

Embodiments of the present disclosure relate to a method for analyzing an imaging quality of an imaging system. The imaging system comprises a spatial light modulator. The spatial light modulator comprises pixel units arranged in an array. The method comprises obtaining a transmittance distribution function of the spatial light modulator based on a structural parameter of the pixel unit, wherein the structural parameter is an aperture ratio.
