VISION CORRECTION SYSTEM AND METHOD, LIGHT FIELD DISPLAY AND LIGHT FIELD SHAPING LAYER THEREFOR USING SUBPIXEL RENDERING

摘要

Described are various embodiments of a digital display device for use by a user having reduced visual acuity. In one embodiment, the device comprises: a digital display medium comprising an array of pixels and operable to render a pixelated image accordingly; a light field shaping layer defined by an array of light field shaping elements and disposed relative to said digital display so to align each of said light field shaping elements with a corresponding set of said pixels to shape a light field emanating therefrom and thereby at least partially govern a projection thereof from said display medium toward the user; and a hardware processor operable on pixel data for the image such that said processed image is rendered to at least partially compensate for the user's reduced visual acuity.
