Abstract: 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.

Abstract: A full-screen optical component, applied to an electronic device comprising a display screen, comprising a backlight module, an active light sensor including a sensor and a light emitter, and a dimmer. The display screen and the active light sensor are located on two opposite sides of the backlight module. The backlight module includes a first prism film and a second prism film stacked on the first prism film. The first prism film includes several first prisms. The second prism film includes several second prisms. The first prism includes a first in-light surface, and the second prism includes a second in-light surface. A display surface of the display screen, the first in-light surface, and the second in-light surface are disposed in parallel. The dimmer is configured to direct light emitted by the light emitter to the first in-light surface at an incident angle that is inclined relative to a vertical direction.

Abstract: An ECG detection method includes in a wearable device, a first electrode detects a first electrical signal and a second electrode detects a second electrical signal, a processor determines a frequency bandwidth based on a current status of the wearable device and/or a status of a user in contact with the first electrode and the second electrode, and the processor determines an electrocardiogram ECG based on an electrical signal that is in the first electrical signal and the second electrical signal and for which a frequency falls within the frequency bandwidth. The wearable device selects an appropriate frequency bandwidth based on the status of the wearable device and/or the status of the user in contact with the first electrode and the second electrode, and then obtains the ECG based on the frequency bandwidth.
