摘要： A display panel (100, 200, 901), a display device (900) and a display method. The display panel (100, 200, 901) includes a first microlens array (10, 20), a pixel island array (11, 21) and a second lens (12, 22). The pixel island array (11, 21) is configured to display a plurality of sub-original images (32a, 32b, 32c, 32d). The first microlens array (10, 20) is configured to converge light emitted from the plurality of sub-original images (32a, 32b, 32c, 32d) so as to obtain imaging light (36, 38), and the imaging light (36, 38) is capable of forming a first virtual image (30). The second lens (12, 22) is on a user viewing side (A) of the display panel (100, 200, 901) relative to the first microlens array, and the second lens (12, 22) is configured to converge the imaging light (36, 38) so as to obtain a second virtual image (31). The first virtual image (30) is a virtual image in which the plurality of sub-original images (32a, 32b, 32c, 32d) are stitched and enlarged, and the second virtual image (31) is an enlarged virtual image of the first virtual image (30).

摘要： 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.
