Abstract: A display driver includes a symbology generator having an electronic architecture optimized for symbology display, along with an interface to a microdisplay. The interface is configured to operatively couple the symbology generator to the microdisplay, to support a display of symbol objects on the microdisplay. The symbology generator may be a one-bit symbology generator configured to provide bi-level pixel data representing symbology to the microdisplay. The symbology generator may be configured to provide video information to the microdisplay in addition to the bi-level pixel data. The symbology generator may be further configured to coordinate the bi-level pixel data with the video information. The coordination may include various types of blending of the symbology data and the video data, or a hybrid mode where symbology data is applied to one set of pixels of the microdisplay, and video data is applied to another set of pixels of the microdisplay.

Abstract: A real-world viewer can include viewing optics positioned along a viewing optical axis for viewing a field of view of the real-world. An active display overlay unit can be optically coupled to the viewing optical axis of the viewing optics, for generating images and directing the images along the viewing optical axis of the viewing optics for simultaneous overlaid viewing of the images in the real-world scene as viewed in the field of view through the viewing optics. The active display overlay unit can be capable of providing full-color luminance of at least t 1200 fL to the ocular of the host system with a luminance to power fL:mW ratio of at least 6:1 or greater or providing monochrome luminance from the active display overlay unit of at least 5000 fL to the ocular of the host system with a luminance to power fL:mW ratio of at least 15:1 or greater.
