Abstract: The present disclosure provides a display panel and a display apparatus. The display panel includes a pixel array layer and a lens array layer. The lens array layer includes micro-lenses arranged along a first direction. The pixel array layer includes pixel islands, each of the pixel islands includes sub-pixel islands arranged along a second direction; each of the sub-pixel islands is divided into sub-pixel groups arranged in the first direction. For two adjacent pixel islands in the first direction, an opaque region is provided in at least one sub-pixel group in an adjacent region of the two adjacent pixel islands, a width of the opaque region is greater than a width of a gap between two adjacent sub-pixels in other sub-pixel groups in a same pixel island. In a same sub-pixel island, gaps between sub-pixels in a sub-pixel group are correspondingly complemented by sub-pixels in other sub-pixel groups.

Abstract: A wearable display device (10), including a display panel (101) and a slit grating (102) disposed on a light-emitting side of the display panel (101). Rays emitted by sub-pixels (101111) in the display panel (101) may be exited from slits (102a) in the slit grating (102). In addition, as the rays emitted by the sub-pixels (101111) may be intersected after passing through the slits (102a), the wearable display device (10) may include at least two imaging faces (K, C). In this way, focus points of two eyes of a user are a same point on the at least two imaging faces (K, C) when the two eyes of the user focus on one of the at least two imaging faces (K, C) by a lens focusing function of the two eyes, so as to avoid visual fatigue of the user. Thus, the wearable display device (10) has a better display effect.

Abstract: The present disclosure provides an optical device, a module, an apparatus and a system for fingerprint identification. The optical device includes: a first lens array including a plurality of first lenses; a second lens array opposite to the first lens array, including a plurality of second lenses; and a light shielding element between the first lens array and the second lens array, the light shielding element including a plurality of light-transmitting apertures. Image focal planes of the plurality of second lenses, object focal planes of the plurality of first lenses, and the light shielding element are coplanar. The plurality of first lenses are in one-to-one correspondence with the plurality of second lenses and the plurality of light-transmitting apertures, respectively.
