Abstract
Disclosed are near-eye displaying methods and systems capable of multiple depths of field imaging. The method comprises two steps. At a first step, one or more pixels of a self-emissive display emit a light to a collimator such that the light passing through the collimator is collimated to form a collimated light. At a second step, the self-emissive display provides at least one collimated light direction altering unit on a path of the light from the collimator to change direction of the collimated light to enable the collimated light from at least two pixels to intersect and focus at a different location so as to vary a depth of field.
