Abstract: A direct view display system (DVDS) and a method to operate it are provided herein. The DVDS may include: a variable optical power element (VOPE); a transparent active image source located with the VOPE on a common optical axis going from an outside scene to an eye position of a viewer; and a time division multiplexer (TDM) configured to control the VOPE and the transparent active image source, wherein the TDM is configured in a certain time period to cause the transparent active image source to be in a transparent state and the VOPE to exhibit no optical power, and wherein the TDM is configured in another time period to cause said transparent active image source to exhibit an image and said VOPE to apply non-zero optical power, for projecting the image onto the eye position at a desirable distance therefrom.

Abstract: An optical system that reduces reflections from an electronic display is provided herein. The optical system may include an electronic display; and a light directing medium configured to steer a plurality of viewing cones into an eye motion box facing said display so that said viewing cones overlap at least partially at the eye motion box plane, wherein a viewing cone is a geometric location only within which a viewer can see light coming from said electronic display.
