Display device and method of detecting heart rate information

Abstract

A display device is provided. The display device includes a base substrate; an encapsulation layer, on the base substrate; an organic light-emitting display element between the base substrate and the encapsulation layer configured to emit a first light passing though the base substrate and a second light passing through the encapsulation layer to display image; a photosensitive layer between the base substrate and the encapsulation layer configured to detect a light reflected from a skin of a user and generate a photocurrent signal; and a photosensitive detection circuit coupled to the photosensitive layer configured to determine heart rate information according to the photocurrent signal generated by the photosensitive layer and output the heart rate information.

Dependencies are inferred from the claim text.
