1. A head mounted display system configured to project light to an eye of a user to display augmented reality image content in a vision field of said user, said head-mounted display system comprising:
a frame configured to be supported on a head of the user;
an eyepiece disposed on the frame, at least a portion of said eyepiece being transparent and disposed at a location in front of the user's eye when the user wears said head-mounted display such that said transparent portion transmits light from the environment in front of the user to the user's eye to provide a view of the environment in front of the user, the eyepiece including:
a transparent emissive display comprising a plurality of emitters, said transparent emissive display further comprising electrodes comprising transparent conductive material, said transparent emissive display configured to emit light into said user's eye to display augmented reality image content to the user's vision field, said transparent emissive display being transparent and emissive over an area, said transparent emissive display disposed at a location in front of the user's eye when the user wears said head-mounted display such that said transparent emissive display transmits light from the environment in front of the user through said transparent emissive area to the user's eye to provide a view of the environment in front of the user; and
at least one occluder comprising a spatial light modulator configured to receive electrical input to cause one or more pixels of the spatial light modulator to be transmissive while other pixels of the spatial light modulator are opaque,
wherein the at least one occluder comprises a distal occluder disposed in an optical path between the transparent emissive display and the environment;
a first distal lens disposed in an optical path between the transparent emissive display and the environment and a second distal lens disposed in an optical path between the transparent emissive display and the environment, wherein the distal occluder is between the first lens and the second lens; and
electronics coupled to the transparent emissive display and to the at least one occluder, wherein the electronics are configured to coordinate operation of the transparent emissive display and the at least one occluder to control an opacity of the one or more pixels of the spatial light modulator, at a frequency greater than that which can be detected by human eyes, while simultaneously controlling a light emission of at least one of the emitters that is aligned with the one or more pixels.
