Document Type and Number:
WIPO Patent Application WO/2020/228634
Kind Code:
A1
Abstract:
A curved-surface lens (130, 230, 330) and a display device (100, 200, 300). The curved-surface lens (130, 230, 330) comprises a plurality of sub-lenses (131, 231, 331) which are arranged around an optical center (182, 382) of the curved-surface lens (130, 230, 330) and are connected to one another; each of the plurality of sub-lenses (131, 231, 331) comprises a first curved surface (141, 241, 341) and a second curved surface (142, 242, 342) which face each other; a plurality of first curved surfaces (141, 241, 341) are mutually connected to form a light exiting surface of the curved-surface lens (130, 230, 330); a plurality of second curved surfaces (142, 242, 342) are mutually connected to form a light incident surface of the curved-surface lens (130, 230, 330); the light exiting surface is closer to the optical center (182, 382) of the curved-surface lens (130, 230, 330) than the light incident surface; the light incident surface is a convex curved surface on the whole and the light exiting surface is a concave curved surface on the whole; the plurality of first curved surfaces (141, 241, 341) and the plurality of second curved surfaces (142, 242, 342) are all free curved surfaces.
