Title: DISPLAY APPARATUS IMAGE RENDERERS AND OPTICAL COMBINERS
Abstract:
Disclosed is a display apparatus and method of displaying, via the display apparatus. The display apparatus comprises context image renderer for rendering context image; focus image renderer for rendering focus image; exit optical element; and optical combiner for optically combining projection of the rendered context image with projection of the rendered focus image to create visual scene. The optical combiner comprises first semi-transparent reflective element; and a second semi-transparent reflective element. The context image renderer is arranged in a manner that projection of rendered context image is incident upon first semi- transparent reflective element and reflected towards exit optical element therefrom. The focus image renderer is arranged in a manner that projection of rendered focus image is incident upon first semi-transparent reflective element and reflected towards second semi-transparent reflective element, and then reflected towards first semi-transparent reflective element, from where projection thereof is allowed to pass through towards exit optical element.
