Abstract: An image capture device including an image capture module and a display panel is provided. The display panel is disposed on the image capture module and includes multiple pixels. Each of the pixels includes a first light-emitting region and a second light-emitting region. The first light-emitting region emits a first light beam. The first light beam is transmitted to the image capture module through a region outside the first light-emitting region. In each of the pixels, a total area of the first light-emitting region is smaller than a total area of the second light-emitting region.

Abstract: A prism of an approximately quadrangle-frustum shape is arranged so that a bottom side, out of two parallel surfaces of the prism, is a placing surface side for a finger. A first imaging unit arranged below a top surface parallel to the bottom surface images an image of the finger transmitted through the top surface. A light source radiates light to at least one side surface of a first set of side surfaces, out of two sets of side surfaces of the approximately quadrangle-frustum shape that face each other. A second imaging unit images the image of the finger transmitted through a second set of side surfaces, out of the two sets of side surfaces. An infrared ray light source radiates infrared ray light into the finger so that the infrared ray light is scattered inside the finger and is received by the imaging unit.

Abstract: Provided are a display panel and a display device, relating to the field of display technologies. The display panel includes a display substrate, a diffusion sheet, a transflective film, and a fingerprint identification circuit. Light of a target wavelength emitted by the fingerprint identification circuit may be reflected by an obstacle, and the light of the target wavelength reflected by the obstacle may be irradiated to the fingerprint identification circuit through at least one through hole in the diffusion sheet. The fingerprint identification circuit performs fingerprint identification according to the received light of the target wavelength reflected by the obstacle. Since an orthographic projection of the fingerprint identification circuit onto the display substrate is within a display area of the display substrate, the fingerprint identification circuit can be prevented from occupying a non-display area of the display substrate. Therefore, the non-display area can be small, and thus, the display device has a relatively high screen-to-body ratio.
