Document Type and Number:
WIPO Patent Application WO/2016/141721
Kind Code:
A1
Abstract:
An optical amplification combined lens, head-mounted display optical system and virtual reality display device. The optical amplification combined lens (2) is used in a head-mounted virtual reality display device and comprises a main lens (21) and a secondary lens (22), the main lens (21) comprising a central region (A) and an edge region (B), wherein the central region (A) comprises a convex lens or a combined convex lens, and the edge region (B) is a focusing thin optical element. The secondary lens (22) is a focusing thin optical element formed with a hollowed-out region. The main lens (21) and the secondary lens (22) are stacked together, and the hollowed-out region of the secondary lens (22) closely fits with a convex portion of the central region (A) of the main lens (21). The display device using the optical amplification combined lens (2) ensures central image quality, and expands a peripheral field of view of a human eye, thus increasing user immersion.
