## Abstract

Various embodiments of the present invention provide for systems and apparatuses directed toward using a display panel to processes display information and non-display information. Further embodiments, utilize a display panel in conjunction with a contact lens assembly configured to process the display information. In one embodiment of the invention, a display system is provided, comprising: a display panel disposed on a head-borne apparatus such that when a viewer is wearing the head-borne apparatus, the display panel is positioned in close proximity to an eye of the viewer such that the eye is unable to focus on the display panel unassisted; and a contact lens having focusing optics that assists the eye in focusing on the display panel. Within the display system, the display panel has pixels and is configured without focusing optics, thereby allowing light emitted by the pixels to diverge in an unfocused manner.
