摘要： A head-mounted display system for the viewing of video or other sources of imagery which comprises a mechanism allowing for a wide range of adjustments for presenting the display to the wearer. The head mounted display device is supported by a headband or other support structure with three independent adjustments giving the wearer a wide range of adjustment capability. One pivot adjustment is in a location in proximity with the ear, the other pivot adjustment is located in close proximity with the pupil of the eye, and a third adjustment allows for the display unit to be adjusted in or out from the wearers head so as to permit convenient use with glasses. The mechanism allows the display to be located within or outside the wearer's primary field of view by utilizing these multiple adjustment locations for the system. The display unit consists of viewing optics, fold mirrors, liquid crystal display devices, and a backlight unit. By folding the light inward to nearly co-located display devices, a single backlight unit can be used.
