Abstract
An electronic device includes a body and a PPG sensor. The PPG sensor includes: a substrate, a first electrode, a light emitting layer, a light receiving layer, a second transparent electrode, and a transparent panel that are integrally packaged. The substrate and the first electrode are both located on one side of the light emitting layer, and the second transparent electrode and the transparent panel are both located on the other side of the light emitting layer. The light receiving layer, the first electrode, and the second transparent electrode are all located between the substrate and the transparent panel, and a polarity of the first electrode and a polarity of the second transparent electrode are opposite. The light emitting layer includes a light emitting pixel for emitting an optical signal, and the light receiving layer includes a light receiving pixel for detecting the optical signal.
