US Patent 9993335 Variable resolution eye mounted displays

A display device (e.g., in a contact lens) is mounted on 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. Additionally, a “locally uniform resolution” mapping may be used to model the variable resolution of the eye. Accordingly, various aspects of the display device may be based on the locally uniform resolution mapping. For example, the light emitted from the sub-displays may be based on the locally uniform resolution mapping.
