The ideal head-ported display for virtual reality requires features not yet simultaneously achievable. We have attempted to satisfy the need for wide field of view, low weight, balance, color range, brightness, binocular vision, etc. With knowledge of their relationships one can not only prevent over-design, but partially sacrifice some less-important capabilities. Conceptual and experimental studies have been performed towards realizing and improving on such a display system.
