Abstract: The present application discloses a display panel and a display device. The display panel includes a fingerprint recognition area. The display panel includes a cover plate and an optically transparent layer. The optically transparent layer at least covers a portion of the cover plate located in the fingerprint recognition area. A refractive index of the optically transparent layer is greater than a refractive index of air and less than a refractive index of a finger. A thickness of the optically transparent layer is an even multiple of a half-wavelength of a fingerprint recognition light ray. Half-wave loss and interference of light are used to improve fingerprint recognition performance.

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.
