Abstract: A display panel and a display device are provided. The display panel includes a display area including a transparent display area and an opaque display area surrounding the transparent display area. The display panel further includes a first substrate layer, a luminous layer, a liquid crystal layer, a first driving layer, and a second driving layer. The display panel is divided into the transparent display area and the opaque display area by combining an organic light-emitting diode technology and a liquid crystal display technology, such that the transparent display area can provide a light channel for a camera and can also display an image, thereby improving a screen-to-body ratio and realizing a real full-screen display.

Abstract: The present application provides a display panel and an electronic device. A first sub-backlight module is arranged in a display area of the display panel, and a second sub-backlight module is arranged in an electronic component area. A light guide plate of the second sub-backlight module can be switched between a light-scattering state and a transparent state, so that the electronic component area can display images and take photos. The first light-shielding member is arranged in an accommodating space defined by the display panel body and the backlight module to avoid light leakage during shooting, so that full-screen display can be realized without light leakage.
