Abstract
A compact display module, such as can be used in wearable computing headset applications, includes a microdisplay with a display surface that is virtually imaged by a lens. The lens is positioned to receive light from the display surface of the microdisplay. The lens defines an angled fold, whereby light from a display generated at the display surface is reflected within the lens to thereby form a virtual image of the display in a virtual image plane that is angled non-perpendicularly relative to the display surface of the microdisplay.
