SPLIT EXIT PUPIL HEADS-UP DISPLAY SYSTEMS AND METHODS

摘要

Split exit pupil (or split eye-box) heads-up display (HUD) systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate a HUD virtual image with a given viewing eye-box segment size. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager. Furthermore, the integrated HUD system can be comprised of a multiplicity of HUD modules to scale the eye-box size to match the intended application while maintaining a given desired overall HUD system brightness.
