  • See-through head or helmet mounted display device
    Patent number: 9703101
    Abstract: A see-through head or helmet mounted display device (10) comprises a see-through member (18) having a see-through area (22). The see-through member (18) includes a plurality of display segments (20; 20a, 20b) for emitting visible light. The plurality of display segments (20; 20a, 20b) is provided within the see-through area (22) in a mutually spaced manner such that the see-through area (22) includes a see-through zone (24) between each pair of adjacent display segments (20; 20a, 20b). The see-through zone (24) allows visible light to pass through the see-through member (18). The see-through member (18) further includes a plurality of holographic optical elements (26; 26a, 26b) provided within the see-through area (22). Each holographic optical element (26; 26a, 26b) is associated with a respective display segment (20; 20a, 20b).
