A smart wearable device includes a detection apparatus and a case, the detection apparatus specifically includes one set of measuring parts and a plurality of sets of light emitting parts; the one set of measuring parts and the plurality of sets of light emitting parts are inlaid into the case and arranged into a polygon, where each of the plurality of sets of light emitting parts and the one set of measuring parts each occupies one of a plurality of angles of the polygon, and a central position of the polygon is at a specified distance to each angle of the polygon. A specific embodiment of the present invention provides a smart wearable device. One set of measuring parts and a plurality of sets of light emitting parts are disposed into a case and arranged into a polygon.

Smart wearable device

An electronic device includes a light guide plate including three grating parts. A first grating part is configured to receive the emitted light through a light incident surface of the first grating part, diffract the emitted light to form a first light, and enable the first light to enter a second grating part. The second grating part is configured to form, based on the first light, a second light propagated in the second grating part, and form, based on the second light, a third light entering a third grating part. The third grating part is configured to form, based on the third light, a fourth light propagated in the third grating part, form an emergent light based on the fourth light, and enable the emergent light to be emitted through a light emergent surface of the third grating part and enter a cover plate.

Electronic device with pattern detection function

A screen module includes an external screen, a first light blocking layer, a substrate, and a reflection layer that are disposed from outside to inside. An imaging unit array is disposed on the substrate, the imaging unit array includes a plurality of imaging units), and a photosensitive surface of the imaging unit is opposite to the reflection layer. A first aperture array is disposed on the first light blocking layer, the first aperture array includes a plurality of first apertures, and the first aperture is used to allow light reflected by an object outside the screen to the reflection layer to pass through. The reflection layer is configured to reflect, to the imaging unit, the light passing through the first aperture. Thus, user convenience can be improved.
