Title: DISPLAY APPARATUS AND METHOD OF DISPLAYING USING OPTICAL COMBINERS AND CONTEXT AND FOCUS IMAGE RENDERERS
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 5 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 the projection of rendered context image passes through first semi-10 transparent reflective element towards exit optical element. The focus image renderer is arranged in a manner that projection of the rendered focus image passes through the first semi-transparent reflective element towards the second semi-transparent reflective element, and reflected therefrom towards the first semi-transparent reflective element, and is 15 then reflected from the first semi-transparent reflective element towards the exit optical element.
