Abstract
A head worn display device is disclosed. Each of two display assemblies includes a first waveguide with a field of view and a second waveguide with a field of view, where the fields of view are overlapped to generate a combined field of view for each of the display assemblies. Each of the display assemblies further includes a first collimator and a second collimator, where each collimator is configured to direct illumination through the waveguide stack along a single axis, and where each collimator is rotated a select angle to offset the combined field of view to merge collimator pupils and generate a seamless total field of view for each of the display assemblies. Each of the display assemblies are rotated a select angle to offset the respective total fields of view along the single axis and generate a seamless wide field of view for the head worn display device.
