Abstract
The present disclosure provides a display panel and an electronic device. A pixel definition layer of the display panel is provided with multiple second openings corresponding to multiple light-sensing sensors, a metal inhibition layer of the display panel is laid in the multiple second openings, and a encapsulation layer of the display panel is disposed to cover the metal inhibition layer and fill into the multiple second openings. By providing the multiple second openings on the pixel definition layer, lights are capable of passing through the pixel definition layer to reach the multiple light-sensing sensors, thereby solving a problem that an existing under-screen optical fingerprint is difficult to be directly applied in OLED products.
