Abstract: A display panel and an electronic device are provided. The display panel includes: an array substrate; a plurality of organic light emitting units disposed on the array substrate; at least one fingerprint identification unit located in a display region at a side close to the array substrate of the organic light emitting units. The fingerprint identification unit performs fingerprint identification according to light rays reflected on the fingerprint identification unit by a touch body. Each organic light emitting unit includes a red organic light emitting unit, a green organic light emitting unit and a blue organic light emitting unit. In a fingerprint identification phase, the red/green organic light emitting unit emits light to be a light source for the fingerprint identification unit.
